INTRODUCTION
Offshore Construction Specialists (OCS) was formed in 2007 from a core group of marine construction engineers to provide construction management, engineering and strategic support equipment services primarily to the offshore oil and gas sector. Our key personnel come from previous careers at J.Ray McDermott in the marine operations department. Our managing and technical director Mr Keith Jackson worked for 17 years in the group the last 5 years as the marine division manager. As a matter of policy under Mr Jackson J.Ray McDermott would execute work peripheral to that being undertaken by the major work vessel (normally executed using third party subcontractors) using in-house resources. Pipeline pre-commissioning, pre and post trenching, flexible flowline / umbilical lay are examples of work that was routinely carried out in-house and not subcontracted. One of the main reasons for doing this was that it prevented the activities of the subcontractor impinging on the work of the high cost marine spread. The work was always planned with maximum operational synergy in mind In JRM large pipeline pre-commissioning projects such as the 650 km West Natuna gas gathering pipeline network and many other major projects were planned and executed in-house. OCS has taken the model developed in JRM and applied it to our own activities. Our equipment is managed and operated by people who come from the same background as the main marine contractor. We help the marine contractor plan the work such that the pre-commissioning has the least impact on operations. We are proactive in highlighting potential issues and ensuring both parties win. Our engineering capabilities are very sophisticated and significantly more advanced than our competitors. OCS has now completed a range of pre-commissioning projects for many different customers with great success. OCS is certified by Nata for pipeline hydrotesting which is the preeminent qualification for pre-commissioning contractors. The OCS organisation has also been qualified to IS0 9001 since 2009. Our in-house equipment spread has grown significantly and is described in detail in this document. OCS is equipped to handle the full range of pre-commissioning activities including flooding, cleaning, gauging, hydrotesting, dewatering, drying and nitrogen packing. We work with established intelligent and caliper pig suppliers to complement our service. We have established long term relationships with key Singapore and overseas vendors. OCS is equipped to handle large projects or discrete project elements depending on the specific needs of the customer. The company has grown steadily since incorporation and now employs 60 personnel of whom 30 are civil/structural and mechanical engineers working with our pre-commissioning technicians. The company office in Toh Guan Rd, Singapore has been leased until 2014 and has room for additional expansion. The office can accommodate customer representatives for liaison as necessary.

SAFETY AND SAFE WORKING PRACTICES
OCS is acutely aware of the dangers involved in the marine construction industry in general and in
pipeline pre-commissioning particularly where high pressure water and air and heavy equipment, chemicals etc combine to create a range of potential hazards if not managed properly. All OCS activities on specific projects are the subject of hazids and risk assessments to ensure levels of risk are reduced to as low as reasonably practical. These risk assessments are ideally attended by the main contractor and the ultimate client. Other specific safety and operational measures that are taken: i) ii) iii) iv) v) vi)
All OCS personnel have appropriate Bosiet offshore sea survival training OCS technicians are Nata qualified and well trained for their specific duties All OCS equipment is provided with a specific safety passport. Offshore hazardous areas are barricaded as required and unauthorized personnel are excluded. All installation aids are properly engineered and subject to structural checks by the OCS CSE group. Appropriate Hazchem sheets are posted in areas where chemicals are in use.
