Company details

Offshore Construction Specialists (OCS) first established an office in the United Kingdom in the year 2000 and expanded operations to Singapore in 2007. Company focus is the provision of 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.----In 2013 the company assisted the Indonesian EPIC Contractor PT Timas Suplindo to acquire the Derrick Pipelay Barge DLB 01 from McDermott and OCS now operates the vessel on behalf of Timas executing a wide range of marine projects. The vessel is equipped with a 12 point mooring, 900 ton revolving Derrick tub crane and full pipelay capability.----OCS has also recently been awarded an engineering contract with Krisenergy for the design of a small platform in Thailand with future prospects to perform fabrication and installation work on the same platform.----Key points related to OCS--Starting with a small core group of key personnel in the company's earlier years, OCS has now expanded its dedicated staff with support operations in the United Kingdom, Australia, India (Bangalore) and Indonesia.--Experienced in all the marine, structural and operational aspects related to the design, fabrication and installation of offshore platforms, pipelines, subsea structures, moorings and all related facilities--Services for OCS clients include Marine Facilities Engineering and Design, Construction Management including related Engineering and Field Support, Marine Equipment Upgrades, Rig up of Specialist Equipment Spreads, Stinger Design, "Build to Operations" Manuals for Marine equipment etc.--OCS operates a jacket Launch Management services and has launched a total of 6 jackets with Jackets up to 8500 metric tonnes in 158 metre water depth.--OCS Operates a suite of Strategic Equipment together with Support Technicians in the marine construction support areas of Pipeline Pre-commissioning, Pipeline Pre and Post Trenching, Free Span Corrections, Pile remediation Flexible Flowline / Cable / Umbilical installations etc. We are continually adding to our equipment inventory.--OCS was certified to ISO 9001 in 2008 and accredited by Nata for pipeline hydrotesting in 2013.----OCS has purchased a facility in the Pioneer district of Singapore to accommodate the Company's management, engineering, equipment groups and a work shop to accommodate our equipment and carry out the maintenance. We intend to develop the facility to a best in class status in our field of operatons to the mutual benefit of OCS and our clients.----2. Onshore and Marine Construction Management.----The onshore and marine construction management capability is what sets OCS apart from other independent engineering companies servicing the industry. All OCS key personnel joined the company after long careers with McDermott during a period where that company was the leading playing in the industry in Asia Pacific. The execution of hard money projects involving every facet of marine construction on a continual basis over many years has given our personnel experience that in the current market is very difficult to replicate. The training regime this provides to OCS younger personnel is invaluable and has led to a company culture where delivery of our service in accordance with customer requirements is of critical importance and where the OCS knowledge base enables new projects to be executed while keeping unnecessary mistakes to a minimum.----This construction management experience has underpinned both our engineering group who provide a solid analysis base to our project teams and our strategic equipment group who execute niche subcontract work associated both with OCS marine construction projects and with stand alone projects managed by third parties.----OCS always aims to fill the gaps that often exist between design engineering and operational constructability.----3. Design and Construction Support Engineering----OCS conducts all design and construction support engineering analyses in-house. Our engineering group has branch offices in both Singapore and Bangalore in India. The group is equipped with all the latest analysis software including Moses, Offpipe (static and dynamic), Orcaflex, Staad Pro, SACS and GRL WEAP. Typical analysis and design work performed by OCS :--Onshore Pipelines, Tank farms, receiving and exporting facilities.--Pipeline and riser design.--Transportation Analyses.--Engineered Lifts.--Jacket Launch Analyses--Pile Launch Analyses--Flexible flowline, Cable and Umbilical installation analyses.--Pipe pull analyses.--Pipelay analyses, Pipeline Davit and Single point lifts.--Pile Drivability analyses.--Heavy Lift and general rigging designs.--Pipe ramp and stinger designs--Jackets, Topsides, Subsea Template and Manifold designs--4. Strategic Equipment Subcontracting.----OCS maintains a suite of portable equipment together with a group of qualified technicians in the following peripheral service / subcontract areas of the marine construction sector which can be leveraged using our engineering expertise. OCS ensures all equipment assets are maintained to the highest standards and uses in-house construction management and engineering skill sets to make best use of the assets thereby creating a win-win situation for OCS and the customer.----The equipment group is controlled by our construction management group.--Pipeline Pre-commissioning (Flooding, Cleaning, Gauging, Hydrotesting, Dewatering, Drying and Nitrogen Packing)--Pipeline Pre and Post Trenching.--Flexible Flowline, Umbilical and Cable Lay and Burial.--Pile Remediation ( Jetting, Airlifting and Remedial Drilling)--Pipeline Free span Corrections.--Jacket Launching.--Mooring Installations.--OCS has built up a considerable resume of completed projects in all the above discipline areas and can provide details on request.----5.
