UK-based First Subsea has delivered cable connectors for the second phase of the Fukushima floating offshore wind demonstration project in Japan.


Two of First Subsea’s connectors have been utilized to link 22kV lines to the facility’s floating 66kV substation ahead of the arrival of the 7MW turbine for phase three.

The new connections will also support phase four of the project, in which a second 7MW machine will be added.

The first phase saw the utilization of two First Subsea cable connectors to link a 22kV cable to a 2MW turbine and the substation.

A third cable connector was also used for a 66kV connection to the floating substation.

First Subsea managing director John Shaw said: "We are delighted that our cable connectors have been chosen for this landmark offshore wind project.

"In Phase 2 we’ve once again demonstrated the ease of installation of the cable connectors offshore."

The project is being developed by a consortium comprising Marubeni, the University of Tokyo, Mitsubishi, Mitsubishi Heavy Industries, Japan Marine United, Mitsui Engineering & Shipbuilding, Nippon Steel & Sumitomo Metal Corporation, Hitachi, Furukawa Electric, Shimizu, and Mizuho Information & Research.

The Japanese Ministry of Economy, Trade and Industry is sponsoring the Fukushima floating pilot wind farm project, which intends to lay the foundation for the world’s largest offshore wind development off the coast of the Fukushima Prefecture.

In October 2014, the consortium revealed that preparatory works for the installation of the 7MW oil pressure drive-type wind turbine on the three-column semi-sub floater at Onahama port, Fukushima, are almost completed.

Delivery of the floater from Nagasaki to Onahama has been started as part of the second term.
