ABBís power systems have been chosen for the first self-elevating wind turbine installation vessel built in Japan, which will support the nationís expanding offshore wind sector

The 28,000gt jack-up ship – a purpose-built, self-elevating wind turbine installation vessel (WTIV) delivered from a Japanese yard – will feature ABB's power and control technologies. The vessel, on order from Japan Marine United, is due delivery to Shimizu in 2022.

Shimizu’s 142m newbuild will feature the greatest lifting and carrying capacity available on a wind turbine installation vessel. Using a 2500t crane capable of a maximum lift height of 158m, the ship will be able to transport and install seven 8MW wind turbines in a single voyage and operate in waters ranging between 10m and 65m deep.

ABB will deliver a closed ring configuration for the vessel’s dynamic positioning (DP) operations, enabling safe and predictable performance with high tolerance in the event of the power plant fault. Whether applied to newbuilds or retrofits, these solutions are claimed to offer increased resilience to network disturbances, as well as timely and precise protection against power loss.

“ABB’s extensive experience with closed-bus systems for dynamically positioned vessels and wind turbine installation vessels in particular had been a decisive factor for this project,” said a Japan Marine United Corporation spokesperson. “We recognise that closed ring solutions improve operational flexibility and engine running efficiency, while increased protection against power loss is a vital safety advantage. ABB’s vast experience with these technologies has been a decisive factor for us.”

ABB’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).

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

In line with ABB’s 'Electric. Digital. Connected.' vision, this vessel will have the capability to leverage the ABB Ability Remote Diagnostic Services for Marine.
