Oil & Gas

Cable, pipeline and umbilical installation and trenching solutions to the oil & gas sector.

With an extraordinary history in delivering subsea projects Global Marine is in a prime position to offer a wide variety of innovative cabling and trenching solutions to the oil & gas sector.

Global Marine has the staff skill set, vessel capability and the subsea equipment available to provide installation and engineering services that deliver; pipeline, cable and umbilical installation and trenching, Permanent Reservoir Monitoring systems (PRM), platform-to-platform connectivity and complete platform to shore installation services.

As a total subsea solution provider, Global Marine offers a proven step-by-step approach for the life of a subsea system.

Installation vessel the Symphony and two Q1400 jet trenchers, soon to join the Global Marine Group fleet, have a track record of successful projects for customers in the oil & gas sector, for cable, pipeline and umbilical installation and trenching. The assets will join the Global Marine Group fleet once the acquisition of Fugro’s trenching and cable laying business is complete.

Broadband data networks are rapidly emerging as the most effective technology to support diverse advances in oil field management, and are installed to manage risk, supervise remote drilling operations and using real-time information to drive field economies.

The announcement of the acquisition of Fugro’s trenching and cable laying business in Q4 2017, now launched under new brand Global Offshore, adds further assets and experience to Global Marine, bringing an extensive track record having worked for oil & gas majors including Shell and BP.

Power cable installation, repair and trenching services to the offshore renewables, utilities and oil & gas markets are delivered by Global Offshore.
