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.
