Introduction 

Purpose of the model courses

The purpose of the IMO model course is to assist maritime training institutes and their teaching staff in organizing and introducing new training courses or in enhancing, updating or supplementing existing training material where the quality and effectiveness of the training courses may thereby be improved. The purpose is also to enhance the capabilities of shipboard personnel who sail on specialized carriers such as a chemical tanker. It is not the intention of the course to compartmentalize the trainee's way of thinking in terms of tanker operation. The idea is to make him/her aware of the specialization of operations specific to a chemical tanker and, sensitize him/her towards the responsibilities that he/she will have to assume on such a vessel. It is not the intention of the model course programme to present instructors with a rigid "teaching package" which they are expected to "follow blindly". Nor is it the intention to substitute the instructor's presence by audio-visual or "programmed" material. As in all training endeavours, the knowledge, skills and dedication of the instructors are the key components in the transfer of knowledge and skills to those being trained through IMO model course material. For those following planned training schemes approved by the administration, it is intended that this training may form an integral part of the overall training plan and be complementary to other studies. The training may be undertaken in progressive stages; for such candidates, it is not appropriate to specify the duration of the learning, provided achievement of the specified learning outcomes is properly assessed and recorded. Because educational systems and cultural backgrounds of trainees in maritime subjects vary considerably from country to country, the model course material has been designed to identify the basic entry requirements and trainee target group for each course in universally applicable terms, and to specify clearly the technical content and levels of knowledge and skills necessary to meet the technical intent of IMO conventions and related recommendations. By successfully completing this course the masters, officers and others on board chemical tankers who are intending to have immediate responsibilities for the cargo handling in port and care in transit will fulfil one of the mandatory minimum requirements of regulation V/1-1, paragraph 5 of the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers, 1978, as amended (STCW Convention). The coverage of the model course is wide in scope and includes chemical tanker safety, fire safety measures and systems, prevention and control of pollution, operational practice and obligations under applicable laws and regulations, thereby covering all training necessary to apply the provisions of Annex II of MARPOL, as amended. In addition, the course covers the managerial aspects on board including a section on risk assessment and safety management, as well as contingency planning in line with the ISM Code. In order to keep the training programme up to date in future, it is essential that users provide feedback. New information to be provided should include amended ISM Code requirements in order to provide better training in safety at sea and protection of the marine environment. Information, comments and suggestions should be sent to the Head of Maritime Training and Human Element at IMO, London.

HTW 3/3/1 Annex, page 5

Use of the model course The instructor should review the course plan and detailed syllabus, taking into account the information provided under the entry standards specified in the course framework. The actual level of knowledge and skills and the prior technical education of the trainees should be kept in mind during the review, and any areas within the detailed syllabus which may cause difficulties because of differences between the actual trainee entry level and that assumed by the course designers should be identified. To compensate for such differences, the instructor is expected to delete from the course, or to reduce the emphasis on, items concerning knowledge or skills already attained by the trainees. They should also identify any academic knowledge, skills or technical training which they may not have acquired. Though lecture and demonstration time may be adjusted to better suit class and student needs based on previous experience, care should be taken not to alter or abbreviate practical assessments. As an advanced level course, these assessments establish trainee baseline competency and represent the minimum knowledge required for the subject. The instructor, using his/her professional judgment, can analyse the detailed syllabus and the academic knowledge required to allow training in the technical area to proceed. The instructor can then design the appropriate pre-entry course or, alternatively, insert the elements of academic knowledge required to support the technical training elements concerned at appropriate times during the technical course. This course is designed to strictly adhere to the requirements of the STCW Convention and related Code, including the 2010 Manila amendments, and builds upon the knowledge and skills included in the IMO Model Course 1.01 on "Basic training for oil and chemical tanker cargo operations". The diagrams and learning objectives included in the basic course may also be used to assist in the development of training material for the "Advanced training for chemical tanker operations" course. Adjustment of the course objective, scope and content may also be necessary if in a country's maritime industry the trainees completing the course are to undertake duties which differ from the course objective specified in this model course. Within the course plan, the course designers have indicated assessment of the time that should be allotted to each area of learning. However, it must be appreciated that these allocations assume that the trainees have fully met all entry requirements of the course. The instructor should therefore review these assessments and may need to reallocate the time required to achieve each specific learning objective or training outcome.



Aims

This course provides training to candidates to be duly qualified in accordance with section A-V/1-1, paragraph 3 of the STCW Code and with specific duties for loading, unloading and care in transit of chemical tanker cargoes. It comprises an advanced training programme appropriate to their duties, including chemical tanker safety, fire safety measures, pollution prevention, safe operational practices and obligations under applicable rules and regulations. The course covers the competence requirements as given in table A-V/1-1-3 of the STCW Code. This course addresses:

-

Advanced level of familiarization with the equipment, instrumentation and controls used for cargo handling on a chemical tanker;

https://edocs.imo.org/Final%20Documents/English/HTW%203-3-1%20%28E%29.docx

HTW 3/3/1 Annex, page 6

-



A greater awareness of the need of proper planning, use of checklists for various cargo handling operations; An enhanced awareness to apply safe procedures at all times when carrying out the various operations on board a chemical tanker; An acquisition of experience in identifying operational problems and solving them; An improvement in the ability to promote safety culture and protection of the marine environment; and An increased ability to assist and coordinate response measures during emergencies.

Lesson plans

After adjusting the course content, if so required, to suit the trainee intake and any revision of the course objectives, the instructor can then draw up lesson plans based on the detailed syllabus. The detailed syllabus contains specific references to the textbooks or teaching material proposed to be used in the course. Where no adjustment has been found necessary in the acquisition of knowledge and proficiency of the detailed syllabus, the lesson plans may simply consist of the detailed syllabus with keywords or other reminders added to assist the instructor in making his/her presentation of the material.



Presentation

The presentation of concepts and methodologies must be repeated in various ways until testing and evaluating the trainee's performance and achievements satisfy the instructor that the trainee has attained the required proficiency under each specific learning or training objective. The syllabus is laid out in the form of acquiring knowledge, understanding and proficiency (KUP) format and each objective specifies what the trainee must be able to demonstrate to meet the learning or training objective. Holistically, these objectives aim to meet the knowledge, understanding and proficiency specified in the appropriate tables of the STCW Code.



Implementation

For the course to be effective considerable attention must be paid to the availability of: -

Properly qualified instructors; Support staff; Rooms and other spaces; Simulators and other equipment; Textbooks, technical papers, and Other reference materials.

Thorough preparation on part of the instructor is the key to successful implementation of the course. IMO has published "Guidance on the Implementation of IMO Model Courses" which can be considered for the development of course material. In certain cases, the requirements for some or all of the training in a subject are covered by another IMO model course. In these cases, the specific part of the STCW Code which applies is given and the user is referred to the other model course.

HTW 3/3/1 Annex, page 7

Part A: Course Framework 

Scope

This course provides training for masters, chief engineer officers, chief mates, second engineer officers and any person with immediate responsibility for loading, unloading, care in transit, handling of cargo, tank cleaning or other cargo-related operations on chemical tankers. It comprises an advanced training programme appropriate to their duties on chemical tankers for their ability to imbibe a safety culture to perform and monitor all cargo operations, familiarity with properties of chemical cargoes, take precautions to prevent hazards, apply health and safety precautions, respond to emergencies, fire safety measures, take precautions to prevent pollution of the environment, and monitor and control compliance with legislative requirements. The course takes full account of section A-V/1-1, paragraph 3 of the STCW Code. This training may be given on board or ashore. It can be supplemented by practical training on board or wherever possible on simulators in training institutions or in a suitable shore-based installation.



Objective

Those successfully completing the Advanced training in chemical tanker cargo operations course should therefore meet the training requirements in accordance with regulation V/1-1 of the STCW Convention, paragraph 6.3.



Entry standards

This course is open to any person who intends to have immediate responsibility for loading, unloading, care in transit, handling of cargo, tank cleaning or other cargo-related operations on chemical tankers. It comprises of seafarers who have qualified in accordance with regulation V/1-1, paragraph 6.1 of the STCW Convention.



Course certificate

Upon successful completion of the course, the trainee should be issued a course completion document for "Advanced training for chemical tanker cargo operations".



Course intake limitations

The number of trainees should not exceed 20 and practical training should be undertaken in small groups of not more than eight.



Staff requirements

The instructor shall have appropriate training in instructional techniques and training methods (section A-I/6 STCW Code).

HTW 3/3/1 Annex, page 8



Teaching facilities and equipment

Ordinary classroom facilities and the ability to project visual aids are sufficient for most of the course content. However, dedicated computer-based training (CBT) modules to be run on an ordinary PC as well as exercises on an operational, hands-on liquid cargo handling simulator, will greatly enhance the quality and result of the course. In such cases sufficient PCs for use by one or two trainees will be required. In addition, appropriate audio-visual equipment will be required if using audio-visual aids in the teaching program. The following equipment should be available: 1. 2. 3. 4. 5. 6. 7. 8. 9.

Resuscitator; Breathing apparatus; Portable oxygen meter; Portable combustible-gas detector; Portable tank scope / multi-point flammable gas (infrared gas analyser); Portable toxic-gas detector and chemical absorption tubes; Portable multi-gas detector; Personal multi-gas detector; and Tank evacuation equipment.

Due to the relatively high cost of obtaining and maintaining items 3 to 8 respective Administrations may approve the use of simulator-based equipment to replace some or all of the gas measuring equipment, provided that the training and competency assessments can be thoroughly and accurately completed.



Use of Simulators

The STCW Convention and related Code set standards regarding the performance and use of simulators for mandatory training, assessment or demonstration of competence. The general performance standards for simulators used in training and for simulators used in assessment of competence are given in section A-l/12 of the STCW Code. Simulator-based training and assessment is not a mandatory requirement for this "Advanced training for chemical tanker cargo operations" course. However, it is widely recognized that well-designed lessons and exercises can improve the effectiveness of training. If using simulator-based training, instructors should ensure that the aims and objective of these sessions are defined within the overall training programme and that tasks are selected so as to relate, as closely as possible, to shipboard tasks and practices. Instructors should refer to section A-I/12, Parts 1 and 2. Note: Some administrations may require additional training at sea or ashore to meet national regulations.



Design

The core technical and academic knowledge, understanding and proficiency are set out in table A-V/1-1-3 of the STCW Code, as shown below. The content of the model course is designed to suit the instructors teaching this course to facilitate optimum delivery and ensuring a high degree of consistency and adherence to the STCW Convention and its related Code leading to certification in advanced training for chemical tanker cargo operations.

Part B: Course Outline 

Lectures

As far as possible, lectures should be presented within a familiar context and should make use of practical examples. They should be well-illustrated with diagrams, photographs, charts where appropriate, and be related to the matter trainees may have learned during seagoing time. An effective manner of presentation is to develop a technique of giving information and then consolidating it. For example, first trainees should be briefed what will be presented to them; then the topic is covered in detail; and finally, a summary of what was presented should follow. The use of audio-visual equipment and the distribution of copies of the presentation as trainees' handouts contribute to the learning process.



Course Outline

The tables that follow list the competencies and areas of knowledge, understanding and proficiency, together with the estimated total hours required for lectures and practical exercises. There are seven competencies which are subdivided into 21 areas of knowledge, understanding and proficiency. Teaching staff should note that timings are suggestions only and should be adapted to suit individual groups of trainees depending on their experience, ability, equipment and staff available for training.

Note: Trainees should have knowledge and understanding of the topics covered in IMO Model Course 1.01 on "Basic Training for Oil and Chemical Tanker Operations" before completing these performance requirements. This knowledge is considered so fundamental for much of the advanced level content within this course that there is merit in reviewing the basic level content quickly before covering the additional elements required at the advanced level. The learning time has been reduced for many elements on the basis that trainees will be reviewing rather than learning much of this content at this level. It may be necessary for some trainees to refresh their knowledge of basic elements before undertaking this advanced level content.

Part D: Instructor's Manual 

Introduction

This manual reflects the views of the course designer on methodology and organization considered relevant and important in the light of his/her experience as an instructor. Although the guidance given here would be of value initially, the course instructors are advised to work out their own methods and ideas, refining and developing it further, and discarding ideas and methods which are not found effective. The course instructors should also bear in mind that preparation and planning constitute a major contribution to effective presentation of the course. The instructor's manual provides guidance on the material that is to be presented during the course. The course material reflects the mandatory minimum requirements for the training and qualifications of masters, chief engineer officers, chief mates, second engineer officers and any person with immediate responsibility for loading, unloading and care during transit and handling, or other cargo-related operations on chemical tankers as specified in regulation V/1- 1, paragraph 5 of the STCW Convention. To show consistency and adherence to table A-V/1-1-3 STCW Code, a mapping is provided for easy reference in Part A of this model course showing STCW's competencies and training outcomes compared to the topics covered in this IMO model course The references used throughout the course are mentioned in Part A "Course Framework" and comprise Teaching Aids (A), IMO Reference Books (R), Text books (T), Bibliography (B) and Videos (V). The course outline, timetable and lesson plan provide guidance on the time allocations for the course material, but the instructor is free to make adjustments as deemed necessary. The detailed teaching syllabus should be studied carefully. Lesson plans or lecture notes may be compiled where appropriate. It is necessary to prepare material for use with audio-visual equipment or for distribution to trainees as handouts. Throughout the course, it is important to stress that rules and regulations must be strictly observed and all precautions taken to minimize risk to safety to an acceptable level and minimize harmful effects to the environment. Topics marked with an asterisk (*) could be taught better using a simulator as provided for in the IMO model course Chemical Tanker Cargo and Ballast Handling Simulator course, which provides a detailed training programme for chemical tanker operations using specially created cargo handling exercises. Separate exercises will have to be made with a brief on how to conduct table-top exercises if simulators are unavailable.



Guidance Notes

While the topics in this course may look very similar to those found in IMO Model Course 1.01, Basic Training for Oil and Chemical Tanker Cargo Operations, it should be noted that the objective of this advanced level course is to equip a person with the necessary knowledge and skills to plan, direct, and carry out safe and environmentally-friendly cargo operations. This person may well be called upon to supervise others as they perform the various cargo-related https://edocs.imo.org/Final%20Documents/English/HTW%203-3-1%20%28E%29.docx

HTW 3/3/1 Annex, page 77 duties. Hence this advanced level course should be presented by the instructional staff very differently from the way they might present the basic level IMO Model Course 1.01. It may be useful to review certain aspects of the learning objectives covered in Model Course 1.01, but the major emphasis here is on a deeper understanding of why chemical tankers are constructed as they are and how the ship design is aimed at creating safer and more environmentally-friendly ships than those of years gone by. One of the objectives of this course is to enable trainees to have a better understanding of various ship designs and characteristics used in modern tanker construction, the practical implications posed by the designs they face and accounting for these factors as they plan, direct and/or carry out cargo operations. Upon completion of this course trainees should be assessed using the criteria in column 4 of the table A-V/1-1-3 STCW Code. Specific training guidance is presented below TOPIC 1

1.1

KNOWLEDGE EQUIPMENT

OF

CHEMICAL

TANKER

DESIGNS,

SYSTEMS

AND

General arrangement and construction

Instructors should note that the students in this advanced level course are required to show a deep knowledge and understanding of the topics covered. They should make every effort to present the material in this light. Rather than reciting facts about the construction and general arrangement of chemical tankers, instructors should endeavour to fully explain the reasons as well as the operational advantages and disadvantages of construction technique of chemical tankers. Trainees should not be asked to memorize all the facts related to construction requirements. Instead, they should be encouraged to know where to look for design standard/requirement as they would need to do on board a chemical tanker. 1.2

Pumping arrangement and equipment

Trainees should understand why a specific cargo pumping equipment is chosen for use and what the practical operational implications these entail including the advantage and disadvantage of each arrangement. On board, the trainee will have to oversee the safe operation of these pumps. They will also need to ensure the safety of those spaces that house the equipment. It is suggested that instructors should not only dwell on facts regarding the pumping equipment and instead approach the subject matter from the "why" and "how" point of view. TOPIC 2

KNOWLEDGE OF PUMP THEORY AND CHARACTERISTICS

The use of diagrams and screenshots to illustrate this section has always proven beneficial for the trainees' understanding. TOPIC 3

PROFICIENCY IN TANKER SAFETY CULTURE AND IMPLEMENTATION OF SAFETY-MANAGEMENT SYSTEM

It is important for the instructor to stress that any effort made toward the creation and maintenance of a successful tanker safety culture cannot be just an intellectual undertaking and another paper exercise. Instead, the instructor should encourage the trainee with the notion that the various instruments and industry guidelines and best practices being discussed are living systems and are heavily interrelated. Their development by the IMO and other entities was carried out for good reasons and their successful implementation requires a

https://edocs.imo.org/Final%20Documents/English/HTW%203-3-1%20%28E%29.docx

HTW 3/3/1 Annex, page 78 genuine and sincere effort by those in charge. Quite simply, the safer the chemical tanker is, the less likely it is to be involved in a safety or environmentally related incident. The instructor should be completely familiar with the relevant instruments and industry guidelines and best practices including the ISM Code, COSWP, and Tanker Management Self-Assessment (TMSA) and should emphasize those provisions that are unique to chemical tankers. Explaining relevant provisions from the instruments and industry guidelines and best practices can be very helpful. Similarly, every effort should be made to highlight how the provisions of these instruments might be implemented differently on a chemical tanker than on other ship types. Where possible, case studies or other real life examples might be very useful in maximizing the results of such efforts. TOPIC 4

KNOWLEDGE AND UNDERSTANDING OF MONITORING AND SAFETY SYSTEMS, INCLUDING THE EMERGENCY SHUTDOWN SYSTEM

There are various guidelines, codes, rules and regulations covering safety and the monitoring of atmosphere in gas-dangerous and gas-safe zones on a chemical tanker which must be understood and always followed. It is important that the instructor emphasizes that it is the combination of technical equipment and the positive attitude of the operator towards implementing safety which relates to assessing risks, and monitoring that the ship's crew complies with procedures and manages safety on board chemical tankers. TOPIC 5

ABILITY TO PERFORM CARGO MEASUREMENTS AND CALCULATIONS

The trainee should understand the filling limits requirements of the IBC Code. The trainees should be able to perform cargo measurements and calculations as specified in Part C of this model course, either on a simulator or by an explanation with the aid of a sketch and the appended diagrams of various gauges used on board chemical tankers. It is important that all relevant information required at management level is readily available. Such information can be ship's ullage tables, ASTM tables, vessel specifications, etc. The instructor needs to be familiar with cargo calculations and measurements at management level, and a demonstration using a loading computer is recommended. TOPIC 6

KNOWLEDGE OF THE EFFECT OF BULK LIQUID CARGOES ON TRIM AND STABILITY AND STRUCTURAL INTEGRITY

Instructors should note that Part C of this course requires that the trainee should be able to use the approved trim and stability manual, perform stability calculations and state various facts about the effect of bulk liquid cargoes on trim, stability and structural integrity. The trainee is not required to describe or explain concepts in any depth, nor is the trainee learning the whole subject of stability and trim as might be found in Model Course 7.01 or 7.03. The focus here should be on the unique properties of bulk liquids and how they will affect the chemical tanker while underway including "sloshing effect" in tanks with large free surface as well as while loading and discharging cargo.

HTW 3/3/1 Annex, page 79 TOPIC 7

7.1

KNOWLEDGE AND UNDERSTANDING OF CHEMICAL CARGO-RELATED OPERATIONS

Loading and unloading plans

The trainee must be able to demonstrate the ability to plan all stages of the loading and unloading operations to include ballasting and deballasting so as to avoid exceeding specified draught, trim or list requirements, while at the same time keeping shear force, bending moments and metacentric height within prescribed limits. Practical demonstration should include preparing a written plan as well as on a vessel loading calculator. i.e. loading computer software programme or on a simulator. The trainee would have to be provided with copies of appropriate ship's capacity, pumping, tank cleaning, ballasting, and ventilation plans along with calibration tables (suggested exercises appended in appendix 2).

ABILITY TO MANAGE AND SUPERVISE CARGO-RELATED RESPONSIBILITIES

PERSONNEL

WITH

It must be understood that it is the supervising officer's responsibility to ensure safe and efficient transfer and retention of chemical cargoes. Delegation of duties to other personnel to assist in that responsibility is required, but does not relieve the supervising officer of his/her responsibility. Therefore, great care and attentiveness must be made to have properly trained crew to assist in any transfer or carriage of chemical cargoes and the crew must be supplied with the proper tools, environment, and a plan which they can easily understand. The instructor is guided to impress on use of relevant publications including the ship's SMS as required by the ISM Code. The instructor should emphasize that once the plan has been created, it is the supervising officer's duty to check that it is being implemented correctly, and to address any changes that may be required TOPIC 11

KNOWLEDGE AND UNDERSTANDING OF THE PHYSICAL AND CHEMICAL PROPERTIES OF CHEMICAL CARGOES

The instructor needs to explain the general properties of chemicals carried by sea and the range of hazards normally associated with them.

11.3

Reactivity of cargoes

The instructor needs to explain that some chemicals require special care to ensure that they remain in a stable condition. Reactive chemicals may be inherently unstable or, when in contact with air, water or other materials may react in a dangerous and violent manner. TOPIC 12

UNDERSTANDING THE INFORMATION IN A MATERIAL SAFETY DATA SHEET (MSDS)

The goal of this general learning objective would be to understand the hazard information of the MSDS and take the necessary precautions to safely handle and store the product. It is recommended that the instructor should conduct an exercise for the trainees to use an MSDS. The instructor should emphasize that MSDS are provided by the manufacturer or supplier of a product and therefore differ and not uniform. 12.1 Explains and demonstrates the operational use of the MSDS Use a sample MSDS sheet and explain each section. It is important to state here that the specific names and content of these sections can vary from one supplier's MSDS to another, but are often similar to the 16 sections of the ANSI Standard for MSDS preparation. If a 9-section MSDS is used then the set of information may be in a different order and with slightly different headings.

APPENDIX 3 CASE STUDIES In this appendix, a few sample case studies on chemical tanker accidents have been presented. The objective is to sensitize the trainees regarding the huge fallout of accidents on board a chemical tanker. The instructor could also use other case studies of chemical tanker related incidents. When discussing the causes, trainees should be actively involved in order to facilitate a better understanding of the causes which led to the incident and to devise preventive actions to avoid similar incidents. . CASE STUDY 1 Tank explosion on board a chemical tanker The incident: Prior to loading cargo the vessel was required to be gas-free and clean cargo tanks. To accomplish this, the dehumidifier system was used to gas-free the tanks. The system consisted of a blower within the forward store, a main line along the deck and branch lines to each cargo tank. Recognizing the risk of cargo vapours passing along the line to the forward store, the system was fitted with individual tank valves, a main line isolation valve, a non-return valve and a spool piece, which the company required to be removed when the system was not in operation to isolate the forward store from the cargo side of the system. One day after loading cargo of naptha, and three days prior to the incident, five crew members entered the forward store as part of a familiarization tour conducted by a junior deck officer. They were met by a strong smell of cargo; however, this was not reported to a senior officer.

Figure: Exploded forward store

https://edocs.imo.org/Final%20Documents/English/HTW%203-3-1%20%28E%29.docx

HTW 3/3/1 Annex, page 139 Two days later and with the vessel being at sea, the ventilation flaps, hatch and door of the forward store were secured. The following day the bosun opened the door of the forward store and turned the ventilation fan on. An explosion occurred and the bosun was killed. Observations: Several valves in the dehumidifier system were passing and the spool piece was not removed after the tank cleaning operation. It was therefore possible for cargo vapours to enter the forward store and with the store room secured for sea, an explosive atmosphere was created. The ventilation fan provided the ignition source. Five crew members smelt cargo vapour in the forward store but did not report this to a senior officer. Some of them were new to the vessel and junior in rank. The spool piece was not removed as required by the company. It was found that the position and design of the spool piece made it difficult to handle. The spool piece is 2 metres above deck height and 50kg in weight. Immediate Cause: Irregularities not reported to senior officers. Root Cause Procedures not followed. Discuss best practices to preventive such incidents: Do not hesitate to report any unusual findings to senior officers. Follow prescribed procedures. On completion of operations spool pieces must be removed and the blanks properly fitted. In order to make them standing out, all portable bends, and spool pieces are clearly marked and labelled. Vessels with awkward and heavy spool pieces, as in this case of the dehumidifier system, should consider alternative arrangements and, if possible, replace the spool pieces with a flexible hose, in consultation with the classification society.

HTW 3/3/1 Annex, page 140 CASE STUDY 2 Over Pressure / Under pressurization of tanks There have been numerous cases of serious tank structural failure as a result of over / under pressure conditions created in cargo tanks due to blocked pressure / vacuum (PV) valves and vent lines leading to them. Incident: A partly loaded vessel arrived and anchored while awaiting the pilot. She was loaded with high melting point cargo (Phenol). While anchored, the crew felt a sudden strong vibration and noticed deformation of deck plating and transverse frame above the cargo tank holding Phenol. The cargo was later observed to have flowed into the adjacent empty cargo tank and into two ballast tanks below the Phenol cargo tank. There was no injury or pollution due to the incident and no breach of integrity to outer hull. Observations: The vessel experienced very rough sea, swell, cold climate, rolling and pitching during the voyage. With the cargo tank fully loaded, cargo sloshed and entered into the mouth of the vent line. Due to the high melting point of Phenol and the low ambient temperature, Phenol solidified at the mouth of the vent line which gradually blocked the vent line completely. With rise in ambient temperature, the tank pressure raised resulting in damage to the deck plating and tank sides.

Immediate cause: Clogging of vent line with high melting point cargo. Root cause: Not applying adequate control measures to take care of cargo property (high melting point). Discuss best practices to prevent such incidents: Always be aware of cargo properties and hazards they present.

https://edocs.imo.org/Final%20Documents/English/HTW%203-3-1%20%28E%29.docx

HTW 3/3/1 Annex, page 141 Pressure/vacuum (P/V) valves and other relief devices should be well maintained and tested to ensure they function as designed for the cargo carried. Such valves and vent lines leading to them can become blocked by cargoes, especially if they have high wax content, high melting points or are polymerizing cargoes. Even when the P/V valves appear to operate freely, flow through vent lines must be confirmed. Always monitor cargo tank pressures to avoid over / under pressurization of cargo tanks Never load cargo more than the allowable limit.

HTW 3/3/1 Annex, page 142

Part E: Evaluation The effectiveness of any evaluation depends to a great extent on the precision of the description of what is to be evaluated. The detailed teaching syllabus is thus designed to assist the Instructors with descriptive verbs, mostly taken from the widely used Bloom's taxonomy. Evaluation/Assessment is a way of finding out if learning has taken place. It enables the assessor (Instructor), to ascertain if the learner has gained the required skills and knowledge needed at a given point towards a course or qualification. The purpose of evaluation/assessment is to:  assist student learning;  identify students' strengths and weaknesses;  assess the effectiveness of a particular instructional strategy;  assess and improve the effectiveness of curriculum programs; and  assess and improve teaching effectiveness.

The different types of evaluation/assessment can be classified as: Initial / Diagnostic assessment This should take place before the trainee commences a course/qualification to ensure they are on the right path. Diagnostic assessment is an evaluation of a trainee's skills, knowledge, strength and areas for development. This can be carried out during an individual or group setting by the use of relevant tests. Formative assessment Is an integral part of the teaching/learning process and is hence is a "Continuous" assessment. It provides information on trainee's progress and may also be used to encourage and motivate them. Purpose of formative assessment  To provide feedback to students;  To motivate students;  To diagnose students' strengths and weaknesses; and  To help students to develop self-awareness.

Summative assessment It is designed to measure trainee's achievement against defined objectives and targets. It may take the form of an exam or an assignment. In Advanced Level Courses, individual summative assessments are assigned and can be interspersed as appropriate throughout the course. As an integral part of the process, ALL have to be INDIVIDUALLY passed. Other exams, including a "Final Exam" may be added at the discretion of the instructor, but they cannot replace or offset any required assessment not passed by the Trainee.

https://edocs.imo.org/Final%20Documents/English/HTW%203-3-1%20%28E%29.docx

HTW 3/3/1 Annex, page 143 Purpose of summative assessment  To pass or fail a trainee; and  To grade a trainee.

Evaluation for Quality assurance Evaluation can also be required for quality assurance purposes. Purpose of assessment with respect to quality assurance  To provide feedback to Instructors on trainee's learning;  To evaluate a module's strengths and weaknesses; and  To improve teaching.

Assessment Planning Assessment planning should be specific, measurable, achievable, realistic and time-bound (SMART). Some methods of assessment that could be used depending upon the course/qualification are as follows and should all be adapted to suit individual needs:  Observation (In Oral examination, Simulation exercises, Practical demonstration);  Questions (written or oral);  Tests;  Assignments, activities, projects, tasks and/or case studies;  Simulations (also refer to section A-I/12 of the STCW code 2010); and  CBT.

Validity The evaluation methods must be based on clearly defined objectives, and it must truly represent what is meant to be assessed; for example, only the relevant criteria and the syllabus or course guide. There must be a reasonable balance between the subject topics involved and also in the testing of trainees' KNOWLEDGE, UNDERSTANDING AND PROFICIENCY of the concepts. Reliability Assessment should also be reliable (if the assessment was done again with a similar group/learner, would you receive similar results). We may have to deliver the same subject to different group of learners at different times. If other assessors are also assessing the same course/qualification as us, we need to ensure we are all making the same decisions. To be reliable an evaluation procedure should produce reasonably consistent results no matter which set of papers or version of the test is used. If the Instructors are going to assess their own trainees, they need to know what they are to assess and then decide how to do this. The what will come from the standards/learning

https://edocs.imo.org/Final%20Documents/English/HTW%203-3-1%20%28E%29.docx

HTW 3/3/1 Annex, page 144 outcomes of the course/qualification they are delivering. The how may already be decided for them if it is an assignment, test or examination. The instructors need to consider the best way to assess the skills, knowledge and attitudes of our learners, whether this will be formative and/or summative and how the assessment will be valid and reliable. All work assessed should be valid, authentic, current, sufficient and reliable; this is often known as VACSR – "valid assessments create standard results".  Valid – the work is relevant to the standards/criteria being assessed:  Authentic – the work has been produced solely by the learner;  Current – the work is still relevant at the time of assessment;  Sufficient – the work covers all the standards/criteria:  Reliable – the work is consistent across all learners, over time and at the required

level. It is important to note that no single method can satisfactorily measure knowledge and skills over the entire spectrum of matters to be tested for the assessment of competence. Care should therefore be taken to select the method most appropriate to the particular aspect of competence to be tested, bearing in mind the need to frame questions which relate as realistically as possible to the requirements of the officer's job at sea. STCW Code as amended in 2010 The training and assessment of seafarers, as required under the Convention, are administered, supervised and monitored in accordance with the provisions of section A-I/6 of the STCW Code. Column 3 – Methods for demonstrating competence and Column 4 - Criteria for evaluating competence in Table A-V/1-1-3 (Specification of minimum standard of competence in basic training for Chemical tanker cargo operations) of STCW Code 2010 sets out the methods and criteria for evaluation. Instructors should refer to this table when designing the assessment. Instructors should also refer to the guidance as given in Part B-II/1 of STCW code, as given below. Evaluation of competence The arrangements for evaluating competence should be designed to take account of different methods of assessment which can provide different types of evidence about candidates' competence, e.g.: 1. 2. 3. 4. 5.

direct observation of work activities (including seagoing service); skills/proficiency/competency tests; projects and assignments; evidence from previous experience; and written, oral and computer-based questioning techniques.

https://edocs.imo.org/Final%20Documents/English/HTW%203-3-1%20%28E%29.docx

HTW 3/3/1 Annex, page 145 One or more of the first four methods listed should almost invariably be used to provide evidence of ability, in addition to appropriate questioning techniques to provide evidence of supporting knowledge and understanding. Assessment is also covered in detail in another IMO Model Course; however, to assist and aid the Instructors, some extracts from the Model course is used to explain in depth. Multiple choice questions Marking or scoring is easier if multiple-choice test items are used, but in some cases difficulties may arise in creating plausible distracters. Detailed sampling allows immediate identification of errors of principle and those of a clerical nature. It must be emphasized that this holds true, in general, only if the test item is based on a single step in the overall calculation. Multiple-choice items involving more than one step may, in some cases, have to be resorted to in order to allow the creation of a sufficient number of plausible distracters, but care must be exercised to ensure that distracters are not plausible for more than one reason if the nature of the error made (and hence the distracter chosen) is to affect the scoring of the test item. Compiling tests Whilst each examining authority establishes its own rules, the length of time which can be devoted to assessing the competence of candidates for certificates of competency is limited by practical, economic and sociological restraints. Therefore, a prime objective of those responsible for the organization and administration of the examination system is to find the most efficient, effective and economical method of assessing the competency of candidates. An examination system should effectively test the breadth of a candidate's knowledge of the subject areas pertinent to the tasks he is expected to undertake. It is not possible to examine candidates fully in all areas, so in effect the examination samples a candidate's knowledge by covering as wide a scope as is possible within the time constraints and testing his depth of knowledge in selected areas. The examination as a whole should assess each candidate's comprehension of principles, concepts and methodology; his ability to apply principles, concepts and methodology; his ability to organize facts, ideas and arguments and his abilities and skills in carrying out those tasks he will be called upon to perform in the duties he is to be certificated to undertake. All evaluation and testing techniques have their advantages and disadvantages. An examining authority should carefully analyse precisely what it should be testing and can test. A careful selection of test and evaluation methods should then be made to ensure that the best of the variety of techniques available today is used. Each test shall be that best suited to the learning outcome or ability to be tested. Quality of test items No matter which type of test is used, it is essential that all questions or test items used should be as brief as possible, since the time taken to read the questions themselves lengthens the examination. Questions must also be clear and complete. To ensure this, it is necessary that they be reviewed by a person other than the originator. No extraneous information should be incorporated into questions; such inclusions can waste the time of knowledgeable candidates and tend to be regarded as 'trick questions'. In all cases, the questions should be checked to ensure that they measure an objective which is essential to the job concerned.

https://edocs.imo.org/Final%20Documents/English/HTW%203-3-1%20%28E%29.docx

HTW 3/3/1 Annex, page 146 Advantages and disadvantages of oral and practical tests It is generally considered advisable that candidates for certificates of competency should be examined orally. Some aspects of competency can only be properly judged by having the candidate demonstrate his ability to perform specific tasks in a safe and efficient manner. The safety of the ship and the protection of the marine environment are heavily dependent on the human element. The ability of candidates to react in an organized, systematic and prudent way can be more easily and reliably judged through an oral/practical test incorporating the use of models or simulators than by any other form of test. One disadvantage of oral/practical tests is that they can be time-consuming. Each test may take up about 1 to 2 hours if it is to comprehensively cover the topics concerned. Equipment must also be available in accordance with the abilities that are to be tested. Some items of equipment can economically be dedicated solely for use in examinations. In general, written exams are excellent forms to evaluate trainees' Knowledge, Understanding and Proficiency of the concepts. However, if the goal is to evaluate a broad spectrum of material using only a sample of questions, care must be taken to protect the security of the exam from the trainees prior to the exam period. It is only natural for the trainees to focus on just the sample questions and not the broad spectrum of the material if the trainees have access to an exam prior to the exam period. It must also be noted that when training facilities use the same exams over multiple sessions of the same course, that it is nearly impossible to protect the security of the exam over an extended period of time; and therefore, training facilities/Instructors should adjust the questions and format of their exams at reasonable periods of time.
