Global Marine Systems Limited, a specialist in subsea cabling and engineering projects, has announced details of a significant submarine fibre optic cable installation project in the Sea of Okhotsk, Russia. This sizeable telecommunications project for customer Huawei Marine Networks (HMN), a Global Marine joint venture partner, will demand 200 days of in-situ vessel time to lay 1,844 km of repeatered cable between strategic locations.

HMN’s customer, Rostelcom, is Russia’s leading long-distance communications provider, and requires a fibre optic telecommunications link from Magadan, the gateway to the Kolymer region at the northern end of the Okhotsk Sea, running south to Ohka at the northern point of Sakhalin Island, then east to the Kamkatcha Peninsula.

Global Marine’s Cable Innovator vessel will be deployed on the project for nearly six months, the project commenced in May 2015 with the cable load. Cable Innovator is a multi-role vessel with DPS-2 capability. She is capable of handling a wide range of subsea tasks required not only by the telecommunications industries, but also by the oil and gas, and deep sea research sectors. The vessel holds an impressive track record of completing major underwater cabling projects.

The Rostelcom project requires some 1,844km of repeatered cable, with the entire system to be ploughburied, in places to a water depth of 1,760m. The systems utilises HMN’s R1 proven repeater technology and NSW’s submarine fibre optic cable.

“We are extremely pleased that our services have been selected for this prestigious project, which requires significant skill in terms of the cable protection requirements, and we very much look forward to working with our joint venture partner, HMN,” says Andy Lloyd, Director, Installation at Global Marine. “Based on Global Marine’s renowned expertise in the installation and maintenance of subsea systems and HMN’s optical network leadership, the project is assured of success.”
