CPDEP & VIPs - VIP Definitions Decision Analysis - DA and D&RA are processes to compare and decide among various alternatives by quantifying the risks and uncertainties inherent in the financial outcomes (i.e., NPV, ROR) of the alternatives. Project Execution Planning - A tool for strategic planning whose purpose is to maximize the probability of project success. It facilitates alignment and decision-making, promotes team building, addresses who, what, why, when, where and how, identifies issues and action items, assures communications, consistency, coordination and control, and has a high impact on project outcome. Technology Selection - Starting with the business driver, this process is used to select and evaluate alternative technologies. Technologies may range from new processing types to equipment selection. Using a selection panel and evaluation criteria aligned with the business driver, the various technologies are researched, developed and evaluated . Project Facilities Objectives - This tool is used to determine the type of facility that is to be designed and constructed. There are nine evaluation characteristics. These characteristics range from capacity to expandability, and maintainability to plant life. Each characteristic is placed into one of four categories ranging from category 1 (low cost) to category 4 (high cost). Value Engineering - Using a structured creative process, this tool uses functional analysis of the project components to identify potential areas for improvements and suggests recommended improvement options. Design to Capacity - This tool optimizes the capacity needed to meet the design conditions stated in the business objectives. Equipment is identified as one of three levels ranging from level one (low cost) to level three (high cost). Equipment & Material Alliances - Long-term and mutually beneficial relationship between owner and one supplier / contractor based on performanc, trust, respect, and commitment. There is no competitive bidding. 6-Oct-97

CPDEP & VIPs - VIP Definitions Project Standards - Industry standards are used as the starting point for standards. Then limited Chevron incremental specifications are added as a supplement. HES Optimization - The HES Risk Management process is used to identify, assess, and develop plans to maximize value by managing significant risks. Four risk areas are included: personnel & public health/safety, environmental, financial (due to HSE incidents), and public concern. Risk reduction measures (prevention or mitigation) are evaluated on a cost benefit basis to ensure efficient resource allocation. Energy Optimization - A methodology for optimizing capital cost, operating cost and operability of process unit, utility system or manufacturing site by identifying the most economical levels of heat recovery and power generation by integrating thermodynamic analysis, economics data, and conceptual design. Constructability Review - This tool uses construction knowledge in the planning, design and construction of facilities. Several formal reviews and checklists are used to ensure issues are identified early. Process Hazards Analysis - Process Hazards Analysis addresses the various design and safety reviews performed by a project team. These include the normal design/safety reviews and the design/safety reviews required by regulation. The process defines a roadmap for performing the various analyses at the appropriate time. Zero Injury Techniques - Techniques that produce excellent safety performance on construction projects: safety preproject / pre-task planning, safety training orientation, safety incentives, alcohol / substance abuse program, accident and incident investigation. Predictive Maintenance - Using advances in instrumentation and sensor technology to monitor machinery performance and make repairs prior to failure. The characteristics monitored include: heat, lubrication, vibration, noise.

CPDEP & VIPs - VIP Definitions Reliability Modeling - This tool uses computer modeling to simulate the reliability of a facility. The model required data for mean failure times and repair times for equipment. Use of model canhelp predict operating factors and is used in the selection of key equipment. IPA Pre-A/R Assessment - An assessment of project progress and quality, performed in CPDEP Phase 3. Rates project against IPA database of similar projects. The assessment establishes the FEL Index, recommends project contingency based on known information, rates project cost estimates, and recommends schedule. The FEL Index is required for GO-36 on projects over $25MM. Post Project Assessment (IPA) - A collection of end-of-job data. It is conducted at the end of Phase 4 and i s performed by IPA. The Downstream assessment uses the IBC data collection form while the Upstream assessment uses the new IPA data collection form. Assessments help to improve estimates for future projects, and the cost ratios developed help with Class 0 and 1 cost estimates for future projects. Business Evaluation (GO-36) - An evaluation of achieved project success, measured against: original project objectives, economic measures, realized economics, plant performance, and product/price forecasts vs. actual. The GO-36 form defines the timing and objectives. Normally the first evaluation is in two years or at full production.

Decision Analysis - Abstract DESCRIPTION: DA and D&RA are processes to compare and decide among various alternatives by quantifying the risks and uncertainties inherent in the financial outcomes (i.e., NPV, ROR) of the alternatives. APPLICATION: DA can be applied during any phase of CPDEP when a decision among one or more alternatives is required. DA is often used during Phase 1 to study viability and identify economic drivers of a concept. Also, DA is often used during Phase 2 to quantify the risks and select among the various alternatives. DETAILS: A DA study involves a multi-discipline work team to analyze the problem and recommend a decision. A decision review board periodically reviews the work team output and provides guidance. The DA process consists of four key steps which include:
Framing the problem to assess the initial situation. Sensitivity analysis to determine ranges of outcome for the alternatives. • Probabilistic analysis to determine ranges of outcome for alternatives. • Appraisal to evaluate the quality of the decision and the value of gathering additional information. • A DA study is typically led by an experienced facilitator. COST & BENEFITS: Numerous DA studies have been conducted by all of the major Chevron opcos. The scope of the decisions has ranged from small projects costing less than $1 MM, to large capital projects costing several hundred million dollars overall. Typical duration and cost of DA range from less than one day and a few thousand dollars to several months duration and exceeding $1 MM. CONTACT: •

Project Execution Planning -
Abstract
DESCRIPTION: PEP is a tool for strategic planning - a means to get all project stakeholders to work as a team in order to plan and make decisions that will determine the project's path and success. It facilitates communication and decision-making, defines issues and risks, and defines answers to the classic questions of Who, What, Why, Where, and How. APPLICATION: The process creates active involvement of the key stakeholders and the pr oject team in project planning and alignment. PEP focuses on developing the project strategies that support the Company's strategic, business, and project execution objectives. DETAILS: A plan is first produced in the earliest stages of a project and then kept up-to-date, always reflecting the latest developments and business conditions. It is a guide for everyone involved with the project. PEP is done with input from everyone involved in the project. The PEP Workbook makes it easy for a project team to implement a structured process to identify unresolved issues and develop strategies to address these issues. The strategies then form the basis for the plan details. COST & BENEFITS: For large projects, the process requires a series of three facilitated workshops. Experience confirms that the time spent in strategic planning is well spent. Most of the causes of cost overruns and schedule delays have their roots in issues that can be and should have been addressed early.
This structured planning process enables the project team to capture these issues early in the planning process and develop strategies to mitigate the consequences. CONTACTS: R. K. (Bob) Fujimoto, (CTN) 842-9298, (email: BFUJ) N. J. Lavingia, (CTN) 842-9868, (email: NJLA) PRODUCTS AND SERVICES:

Technology Selection - Abstract DESCRIPTION: This is a formal, systematic process by which a project searches for technology which may be superior to that currently employed and improves our competitive advantage. APPLICATION: Ideally, Technology Selection is started very early in Front-End Loading for process selection. Technology selection selection can also be used for equipment equipment and materials materials selection. DETAILS: The 1994 Corporate Strategic Plan reinforces the importance of technology by stating that the Corporation needs to "ensure that technology is used to our competitive advantage".
In Front-End Loading, decisions made can have a major impact on the financial success of the project. Technology chosen without a well thought-out plan can lead to cost overruns, longer schedules (especially start-up), and lost opportunities in the marketplace. The basic process involves commissioning a technology selection team which goes through several basic steps of information gathering, speculation, analysis, development, and presentation. COST & BENEFITS: Technology selection is developed from discussions with benchmark companies and internal teams that have used a technology selection process. Some projects have already used a systematic selection process like the El Segundo Acid Plant or incorporated innovative outside technology such as Tengizchevroil Demercaptanization. CONTACTS:

Project Facility Objectives -
Abstract
DESCRIPTION: PFOs establish the characteristics of the facility needed to meet business goals. It sets criteria for facility reliability, expandability, automation, life, expected s tream factor, likelihood of expansion, production rate changes with time, product quality, and product flexibility. PFO can be used to set a project philosophy for marginal investment decision-making, design allowances, redundancy, sparing philosophy, and room for expansion. APPLICATION: PFOs should be used on projects of any size and initiated prior to "manning-up" the project. DETAILS: Overall objectives are set early based on information provided by the SBU funding the work. Included in these can be conceptualized descriptions of the expected stream factor, facility life, likelihood of expansion, projected production rate changes with time, product quality, product demand, feedstock availability, feedstock type, degree of commercialization of the technology, etc. These determine the redundancy/sparing philosophy, allowances for future expansion or changes, etc., of facilities necessary to meet the business goals. This process establishes the Project Facility Objectives. PFOs should be revisited during the latter stages of project development. They should also be used to orient new members of the project team. COST & BENEFITS: Initial use of this tool requires only a few hours. PFO help bring all members of the project team into alignment through discussion and consensus. This helps keep the cost of the project down by eliminating needless extra conservatism often designed into a project at lower levels. CONTACTS:

Value Engineering - Definition A multi-discipline, systematic, and proactive process that is targeted at the design itself. The objective is to use VE to develop an item or facility which will yield the least life-cycle cost or provide the greatest value, while also meeting all functional, safety, quality, operability, maintainability, durability, and other criteria established for it.
Value Engineering - Abstract DESCRIPTION: VE is a creative, organized approach to optimizing cost and/or performance of a facility or system. A study team identifies items which may not add value or are not aligned with the basic project objectives. VE is conducted during Front-End Loading, CPDEP – Phase 3. APPLICATION: VE, for maximum benefit, should be conducted during process development as process simplification and later on in FEL for facility optimization. VE studies have been conducted on projects as small as $100,000. VE has been used on refinery, chemical plant, environmental, and upstream projects, both domestically and internationally. DETAILS: A Value Engineering Study brings together a multi-discipline team in which most of the members are not directly associated with the project at hand. This brings a fresh perspective with no preconceived paradigms. The study team works under the direction of an experienced facilitator. It follows an established set of procedures to completely review the project in an orderly manner, making sure customer requirements are fully understood and reflected in a cost-effective solution. COST & BENEFITS : For very small projects, VE studies can be conducted in as little as four hours; for medium-sized projects, two to three days; for large projects, one week. Cumulative benefit to cost is on the order of 90:1. CONTACT:

Design-to-Capacity
Design-to-Capacity
Design-to-Capacity - Definition A systematic process to evaluate the maximum capacity of each major piece of equipment. Helps prevent the compounding of “safety factors”. • Eliminates Excess Capacity (Fat) • Specifies Design Factor • Reduces Equipment Cost
Design-to-Capacity - Abstract DESCRIPTION: Often, equipment is specified with a "design factor". These factors can result in oversized equipment or systems and can be compounded as the design passes from engineering discipline to discipline and on to suppliers. These factors add investment cost but may not provide a return if this "extra capacity" is not fully utilized. This Value-Improving Practice (VIP) reduces the "excess fat" that does not meet project objectives. APPLICATION: Design-to-Capacity can be applied to grass root and retrofit projects, process plants, off plot facilities, and production facilities. DETAILS: Design-to-Capacity is a two-step process. The first step is to determine the overall facility design factors early. The second step is to choose how much design flexibility is required for each major piece of equipment or system. Different equipment types or parts of the plant may be built to different levels of conservatism. This step is done after the preliminary process flow diagrams are developed. COST & BENEFITS: Design-to-Capacity can save up to 15% of the capital cost. In the past, this costly over capacity was automatically built in without any discussion or input from the business side. The over capacity adds investment cost but may not provide a return if this "extra capacity" is not fu lly utilized. CONTACTS:

Design-to-Capacity LEVEL OBJECTIVES/CHARACTERISTICS LEVEL 1
6-Oct-97
LEVEL 2
LEVEL 3
Build a facility that only needs to operate at well defined, unchanging conditions over its total life. This tighter, but less capital expensive design might take longer to start-up or could require minor debottlenecking to reach nameplate capacity. This facility could have trouble handling unforeseen operating conditions not considered in the original design.
Build a facility with just enough flexibility to operate easily at nameplate capacity for most design cases. It may require minor debottlenecking to handle unforeseen variations in operating conditions or to operate above nameplate.
Build a facility with additional flexibility to operate at the limiting design case, or handle future unknown operating requirements. There is high assurance that the facility with meet and exceed the nameplate requirements. The facility will be easier to start-up, but will have a higher capital cost.
The incentive to build this type of facility is the lower capital cost. It is ideal for situations where the operating conditions are well defined and not likely to change.
The incentive to spend the extra capital cost is to provide additional flexibility for future overcapacity or changing conditions.
The incentive is that the excess capacity will allow for quickly adapting to changing operating conditions. Excess capacity is planned for.

Abstract
DESCRIPTION: "Equipment Supplier Alliances" (ESA) is defined as Chevron's project-specific, long-term,
mutually beneficial relationship with one qualified supplier of highly engineered equipment. With this process the supplier is involved "up front," developing a long-term association based on performance, trust, respect, and commitment. APPLICATION: Can be used for highly engineered equipment, larger orders of "like" equipment/materials, and
critical path equipment/material. DETAILS: Most equipment is purchased by traditional methods, i.e., competitive bid. ESA is a relatively new way of
acquiring engineered equipment for a specific project. An expert team of Chevron perso nnel, suppliers, and contractors produces a well-designed, well-scoped, and cost-effective specification. Working with suppliers during the project's early planning stages translates into: a) acquiring better equipment and systems design, b) meeting critical path equipment deliveries, and c) ensuring quality fabrication and installation of equipment. An innovative approach to the purchase of highly engineered equipment, ESA's roots lie in the common goal of Chevron: continuous improvement. COST & BENEFITS: There is some up-front effort to identify the equipment or materials where this process is
effective and the apply the ESA process. In all cases where this process has been used, there have been significant savings that far outweigh the cost of implementation. CONTACT:

A process to acquire and use project standards that minimize project cost and improve communications between project engineers and pre-qualified vendors.
DESCRIPTION: Engineering standards and specifications can affect manufacturing efficiency, product quality, operating costs, and employee safety. The cost of a facility is increased by the application of traditional Chevron specifications that exceed the actual needs of the specific facility to be designed. APPLICATION: These standards are applicable to all projects and locations. DETAILS: The Minimum Project Standards are comprised of three types of documents: Supplemental Information for API specifications, Chevron Specifications, and Data Sheets.
•
Where an industry standard exists, Chevron presents requirements as a supplement, including a recommendation for Chevron's selected owner preference.
•
Where no industry standard exists, Chevron creates stand-alone documents.
Minimum Project Standards are different from the "gray" manuals. They were developed for technical personnel who have a working knowledge of the subject to help minimize vendor inspection and testing requirements. As such, it is assumed that vendors are pre-qualified and that their quality assurance programs have been endorsed by Chevron. COST & BENEFITS: The development of these standards were to eliminate over- and under- designed equipment and facilities, optimize Life Cycle Costs, and prevent incidents. Equipment purchased using Minimum Project Standards costs 3-5% less than traditional Chevron standards. CONTACT: F. M.

Energy Optimization - Definition A methodology for optimizing capital cost, operating cost and operability of process unit, utility system or manufacturing site by identifying the most economical levels of heat recovery and power generation by integrating: • Thermodynamic Analysis • Economics Data • Conceptual Design
Energy Optimization - Abstract DESCRIPTION: Energy Optimization is a way to identify, understand, and optimize energy use for the operating lifetime of a project. APPLICATION: Energy often represents the largest element of the ongoing operating costs once a project is completed. With project lives at 30 years or beyond, energy operating costs must be an important project consideration, starting at the early stages of project development. Energy Optimization provides a methodology for understanding and then optimizing energy use. DETAILS: Projects afford a unique opportunity to address and improve energy performance of the site and facility. Energy considerations appear throughout CPDEP. Unlike some of the other VIPs, Energy Optimization can not be conducted and completed in a three day workshop. Energy Optimization is not a stand alone process, instead it must be woven into normal project activities such as objective setting, process design, equipment specification and selection, detailed design, and operating philosophies and practices. Energy measurement and management systems must be installed to track project performance against pre-established metrics. Tools such as Steam System Models, Fuel System Models, Pinch Analysis, FEL Energy Checklist, etc. are utilized to properly size utility systems and optimize process design . Early involvement of specialists (CXTC, local, contractors) can quickly lead to a cost effective and reliable design. Specialists should also be used to assist in the development of specifications and the purchase of large equipment such as gas turbines, boilers, compressors, pumps and furnaces. COST & BENEFITS: Integrating Energy Optimization into the process design, selecting the best alternatives, and using proven tools will optimize the capital and energy costs over the entire operating life of the project.

Constructability Review -
Abstract
DESCRIPTION: Construction Industry Institute (CII) defines "constructability" as "the optimum use of construction knowledge and experience in planning, design, procurement, and field operations to achieve overall project objectives". APPLICATION: The concept of "constructability" should be implemented on all projects. DETAILS: "Constructability" drives the project to excellence in design and execution. Critical to project success, implementation begins in Front-End Loading with a focus on assessing construction viability, cost variance from the ideal and identification of costly or fatal fl aws due to regulatory, environment, site, or infrastructure restrictions.
Prior to funding, the Construction Manager is brought on the project team to champion constructability and to participate in final scope development. A project-specific constructability process is developed and integrated into the Project Execution Plan. COST & BENEFITS: The cost for implementing a constructability process on a large project will vary. The cost could range between $50,000-$150,000 depending on the resources available and the uniqueness of the project. Constructability can be implemented in a small projects group similarly.
The return on the time spent ranges from 5-20% of total project cost. A major benefit is elimination of rework and delay in the construction and start-up schedules. CONTACTS:

Process Hazards Analysis - Abstract DESCRIPTION: PHA serves as a roadmap to plan appropriate hazards reviews at a time that optimizes contribution and impact to the project. By coupling the normal design reviews with mandated reviews, the projects are able to avoid unnecessary duplication and comply with regulations (OSHA 1910). APPLICATION: PHA is intended to provide sufficient background information to permit a project team to identify, assess, and plan activities related to a Process Hazard Analysis. DETAILS: OSHA's Process Safety Management Rule (29 CFR 1910.119) mandates minimum criteria for review of a project during project development and for the review of changes to the design that might affect the safe operation of a facility. The rule is performance-based and charges the owner and designer with the responsibility of performing the quality and quantity of reviews appropriate to determine and evaluate the hazards of the process being reviewed. PHA provides a roadmap that assists the project team in planning PHA-related reviews, the purpose of each review, the data required to perform the review, the resources required, the expected results, and a suggested timing for the reviews. COST & BENEFITS: By coupling the normal design reviews with mandated reviews, projects are able to avoid unnecessary duplication and comply with the regulations. CONTACT:

This tool can help determine the value of sparing, bypass, and alternative operating modes contemplated in the design and factor it into the Life Cycle Cost. APPLICATION: Most applications will be FEL. It can also be used during operations to evaluate and influence maintenance practices on production availability. It is often done by a third party, such as IPA, and may employ the MAROS software. DETAILS: The Reliability Modeling Process has five distinct steps:
1. Understand the facility under consideration. 2. Data collection on facility, equipment, and failure rates. 3. Data analysis and computer modeling. 4. Case runs and review. 5. Discussion of results. The information needed includes: Process description • PFDs with major equipment identified • Equipment list with sizes, capacities, and vendor/ supplier information including the make and model numbers • COST & BENEFITS: The cost of a reliability modeling study will range from $25-50M depending on the complexity of the facility/process being reviewed. Cost is a function of data collection efficiency and the number of cases or alternatives to review. A 10:1 return on investment is not uncommon. CONTACTS: G.W.

Primary Objectives
The primary objectives of the Project Business Evaluation Review are to: •
Improve the decision-making process used within Chevron for investing capital
•
Identify possible insights that will benefit development of business plans
•
Provide an opportunity to assess future plans for the facilities
•
Provide feedback to those experts who provided assessments in the initial Decision & Risk Analysis
The Project Business Evaluation Review is conducted after one or two years of operating data are available, or as soon as appropriate production and market response are realized. A multifunctional team with third party participation is recommended to conduct the review and enhance learning and sharing. Subsequent reviews should become part of the normal business planning process.

CPDEP and VIPs/BPs - Exercise Exercise 1: The scope of work on a project was divided into two contracts - an onplot contract and an offplot contract. The onplot contractor designed the facility, which included storage tanks for the products. The offplot contractor transported the products from these tanks into another set of tanks 2 miles away at a marine terminal. The products were then loaded to a tanker for shipment. Also, each tank was equipped with three 50% pumps.
