ABB Tech for Japanese Wind Turbine Installation Vessel

ABB has won a contract to provide the power systems for Shimizu Corporation’s wind turbine installation vessel (WTIV).

The self-elevating platform is designed to handle turbines with an individual capacity of 8MW or more, and is said to be the first such vessel to be built in Japan for the local offshore wind market.


ABB will deliver a closed ring configuration for the vessel’s DP operations, which is said to offer increased resilience to network disturbances, as well as timely and precise protection against power loss.

The company’s scope of supply also covers the delivery and system integration of generators, high voltage switchboard system, the variable speed drives and motors for main propulsion and bow thrusters, and the Power and Energy Management System (PEMS).

The 142m long vessel is being built by Japan Marine United Corp. and is due to be delivered to Shimizu Corp. in 2022.

According to ABB, using a 2500t crane capable of a maximum lift height of 158m, the vessel will be able to transport and install seven 8MW turbines in a single voyage and operate in waters ranging between 10 and 65m deep.

“We are honored to work with Shimizu Corp. and Japan Marine United Corporation in delivering this landmark vessel to the Japanese market at this important stage of the country’s renewable energy strategy,” said Juha Koskela, Managing Director, ABB Marine & Ports.

“Sustainability is a core commitment for ABB Marine & Ports deliveries, and we are thrilled to secure this benchmark order that will be key in supporting offshore wind energy developments in Japan.”
