ABB has been commissioned to deliver an advanced power system for a purpose-built wind turbine installation vessel, (WTIV) being built in Japan to support the installation offshore wind components.

The 28,000-GT jack-up will be delivered from builder Japan Marine United Corp. in 2022. It will be operated by Shimizu Corp. and feature a 2500-ton crane capable of a maximum lift height of 158 meters. The 142 metre ship will be able to transport and install seven 8MW wind turbines in a single voyage and operate in waters ranging between 10 and 65 meters deep.

ABB will deliver a closed ring configuration for the vessel’s dynamic positioning (DP) operations. It stated that this will enable safe and predictable performance with high tolerance in the event of the power plant fault. ABB claims these solutions offer increased resilience to network disturbances, as well as timely and precise protection against power loss.

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).

The vessel will have the capability to use ABB Ability Remote Diagnostic Services for Marine. The network uses remote equipment monitoring and data analytics to enable predictive maintenance, planned interventions or even remote technical assistance, supported from seven existing shore-based ABB Marine & Ports’ Collaborative Operations Centres staffed by ABB.

“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 the Japan Marine United Corporation spokesperson. “We recognize 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.”

“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.”
