Global Marine Systems Wins Offshore Tampnet Contract

Global Marine Systems Limited, a UK-based specialist in subsea cable engineering projects, has announced that it has secured a contract from Tampnet. The contract, with work being undertaken in 2018 by one of the Company’s key installation vessels, is designed to further enhance inter oil-field communication networks in the North Sea. 

The project, which is the sixth contract award to Global Marine from Tampnet, focuses on the installation of a platform to platform fiber optic cable.  It will incorporate the laying and burial of approximately 75km of fiber optic cable from an existing Branching Unit (BU) to the platform.  In addition, a Cable End Module (CEM) and a further three BUs will be installed at selected locations along the route.  Prior to the installation, Global Marine will conduct a detailed marine route survey and burial assessment report providing comprehensive data that will deliver fundamental information, crucial to ensuring the successful installation of this project.

Subsea assets will be utilized to conduct cable burial to 1m below the seabed in a water depth of 75m.  A CEM will be installed within the platform 500m zone.  The installation of a CEM is not new to Global Marine, as the company is well versed with the rigorous requirements in terms of seabed positioning as well as the lay tolerances required for precise deployment. Laying and burial of the fiber optic cable will commence upon successful installation of the CEM, towards an existing BU where a previously installed cable end will be recovered and the fibre optic cables jointed.  The scope of this project, including the buoying of cable ends, allows for future development of the system to other platforms in the North Sea if required.
