Introduction to OCS

OFFSHORE CONSTRUCTION SPECIALISTS (OCS) INTRODUCTION

OCS commenced operations in Singapore in 2007. The Company focus is the provision of construction management, engineering, strategic equipment 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 OCS has built up a mature Design and Construction Support Engineering group equipped with the latest industry software to provide engineering analysis required for marine structure and pipeline design, transportation studies, pipeline and cable lay, pile drivability, mooring analyses, engineered lifts, jacket launch, float and upend, topside floatover installation 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.
