Global Marine installing telecoms cables in Sea of OkhotskProjects and Operations // September 24, 2015
Global Marine Systems Limited says it is approaching completion of a fibre optic cable installation project it is undertaking in the Sea of Okhotsk.
The telecommunications project - for customer Huawei Marine Networks (HMN), a Global Marine joint venture partner - demanded 200 days of in-situ vessel time to lay 2,000km of repeatered cable between strategic locations.
HMN’s customer, Rostelcom, is Russia's leading long-distance telephony 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 has been deployed on the project which commenced in May 2015. Cable Innovator is a multi-role vessel with DP2 capability.
The Rostelcom project requires some 2,000km of repeatered cable, with the entire system to be plough buried to a water depth of 1,700m. The system utilises HMN’s R1 proven repeater technology and will be the first significant use by HMN of NSW submarine fibre optic cable.
