OFFSHORE CONSTRUCTION SPECIALISTS (OCS) INTRODUCTION

1. Overview.

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.

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.

The company office in Toh Guan Rd, Singapore has been leased until 2016 and has room for additional expansion. The office can accommodate customer representatives for liaison as necessary.

2. Marine Construction Management.

The 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
