OFFSHORE CONSTRUCTION SPECIALISTS (OCS)INTRODUCTION
Offshore Construction Specialists (OCS) was formed in 2007 to provide construction management, engineering and consulting services primarily to the offshore oil and gas sector. Changing industry dynamics has resulted in a continued shortage of properly qualified and motivated engineers with the right experience to deal with the range of complex issues faced by offshore operators and contractors. OCS employs a base load of personnel with extensive experience in all facets of marine construction. OCS uses this depth of experience to mentor and train new personnel and has built an organisation capable of taking on the most difficult projects. To complement our Operational and Field Engineering staff, we have developed a Construction Support Engineering group equipped with the latest industry software to provide engineering analysis required for transportation studies, pipeline and cable lay, pile drivability, mooring analyses, engineered lifts, jacket launch, float and upend, and a range of other applications.
OCS fills the gap that often exists between design engineering and operational constructability.
To make further use of its intellectual capital, OCS has developed a suite of strategic portable equipment which can be leveraged using our engineering expertise. The equipment is used in peripheral marine construction areas where support engineering expertise is essential and includes equipment to perform pipeline pre-commissioning, pipeline pre and post-trenching, cable & umbilical lay, pile remediation, jacket launching and mooring pile installation. OCS employs a small equipment group to ensure these equipment assets are maintained to the highest standards and uses in-house engineering to make best use of the assets thereby creating a win-win situation for OCS and the customer.
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 over 50 permanent staff personnel of whom 30 are civil/structural engineers specialising in marine construction engineering. 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.
OCS Clients have come from both the oil company and marine contracting side and include: ConocoPhillips, Star Petroleum, Hess Indonesia, Asia Petroleum Developments (Salamander), EMAS, Larsen & Toubro, SapuraAcergy, TLO SapuraCrest, Heerema, NorCe, Offshore Marine Contractors, Vietsovpetro (VSP), Timas Suplindo, Kangean Energy, Nippon Steel, Newfield Peninsula Malaysia, Franklin Offshore, M3 Energy, Sarku, Hako Offshore, Global Industries, Sea Drill, Origin Energy, McConnell Dowell, MRTS, Allseas and Leighton Australia.
In the 12 months to end of February 2013 OCS added some significant projects to the company resume :
Umbilical engineering and Lay supervision for MRTS in East Russia.
Complete engineering and Project Management for the PTTEP Zawtika Wellhead platform and infield pipeline project for PTTEP in Burma subcontracting to Larson and Toubro. Project has involved 3 wellhead platforms with launch jackets from 7000 to 9000 tonnes, single piece 84” piles 143.5 metres in length weighing over 450 tonnes and two 18” infield pipelines in water depths from 130 to 160 metres. The DLB LTS 3000 was the major work barge employed on the project.
Pipeline Post Burial for the Chevron Domestic Gas Pipeline from Barrow Island to the Australian mainland subcontracting to Clough Sea Trucks JV. OCS provided the jet sled, pumps, operating crew and the full suite of support equipment to operate the equipment operating off the Java Constructor and the Kalinda pipelay vessels.
Complete engineering and project supervision for a twin 42” pipeline pull from the Queensland mainland in Australia to Curtis Island for QCLNG and APLNG. The dual pipe string 3.9 km in length and weighing approximately 15,000 tonnes was laid out on rails. 3,500 tonnes of buoyancy along with a 450 ton linear pull winch and 3,300 metres of 3.5” wire rope were employed on the Pipepull. OCS was subcontracted by the main Contractor MCJV.
Lift Engineering and mooring studies for the DLB Norce Endeavour for heavy lifts associated with the installation of the Gorgon LNG jetty on Barrow Island off Western Australia. OCS was subcontracted by Solstad Offshore.

SPECIALIST SERVICES FOROPERATORS
OCS provides operators the ability to review and assess their installation options, marine construction budgets and negotiate technical details with potential contractors.
OCS has experienced personnel who can develop project contracting strategies, prepare marine construction RFQs, ITBs, perform vessel inspections and conduct detailed technical discussions with contractors based on a given scope of work. OCS can both plan the execution and supervise the implementation of a project.
Engaging OCS at the early stages of a project allows operators to minimize costly scope of work errors, adopt the contracting strategy most suited to the work at hand, identify contractors with the equipment and expertise required for their project, avoid delays due to poor planning or timing and provide operators the resources to manage interfaces in any offshore project.
Utilizing OCS allows operators to perform owner managed installations using drilling rigs or other equipment taking maximum advantage of field development equipment synergies. OCS can provide the construction experience and know-how for different methodologies and manage the work on behalf of the operator as required.
OCS provides marine contractors with key offshore construction management and execution expertise during the project tendering, planning and execution phases of a project.
OCS has experienced personnel who can assist with tender preparation and technical contract reviews and/or negotiations.
During the planning and execution phases OCS specialist personnel can perform the detailed planning including preparation of installation procedures and subcontract packages. OCS can also assist with vessel and equipment mobilization and supervision of offshore installation activities.
OCS has the personnel to relieve contractors of the high cost of increasing their baseline, permanent employee levels in order to deal with one off projects. With the high cost of construction spreads and a competitive contracting environment, good planning and well thought out execution strategies can make the difference between success and failure. OCS helps contractors make that difference.
OCS maintains a pool of portable marine construction support equipment. This equipment is controlled by OCS field engineering staff and marine construction team. The equipment can be contracted separately or as part of a larger marine construction package. For details and specifications of OCS equipment see MARINE CONSTRUCTION SUPPORT EQUIPMENT.
OCS is made up of an experienced team of marine construction specialists. All OCS personnel have direct experience at the "coal face" of hard money offshore oil and gas related marine construction. Further details can be provided on request. Refer to OCS PERSONNEL.
