Wartsila has received an order to deliver its solutions for a new wind turbine installation vessel (WTIV) that is being built at the China Merchants Heavy Industry (Jiangsu) yard.

As part of the order, the company will supply four Wartsila 32 and two Wartsila 20 engines, the Wartsila NOx Reducer (NOR) system, five steerable thrusters and one Wartsila tunnel thruster.

Wartsila stated that the GustoMSC NG-14000XL-G design jack-up vessel is being constructed for Norway-based wind turbine generator (WTG) installation contractor OHT.

This vessel is the first among the two modernised WTIVs to be included in the OHT fleet.

It will be designed to carry out offshore wind turbine deployment as well as XL monopile foundations.

With a maximum lifting height of approximately 165m, this ship will be equipped with a telescopic crane, which will have a maximum capacity of 2,500t.

OHT newbuild project manager Torben Mikkelsen said: “There is rapid growth in demand for the installation of offshore wind turbines, and the vessels designed to carry out this construction work need to be state-of-the-art.

“The same applies to the propulsion solutions because reliable and efficient dynamic positioning is essential in all sea conditions. The full scope of Wartsila solutions will provide the operational and environmental performance demanded for the next-generation market.”

Wartsila stated that the compact design and lightweight feature of its thrusters are key benefits, as the weight of all on-board equipment can be important for a jack-up vessel.

In a statement, Wartsila said: “Effective station-keeping is enhanced by the thrusters’ proven retractable system, which has an energy-efficient 8-degree tilting feature. This reduces the power need and, therefore, also fuel consumption.

“The thrusters also deliver thrust that can be up to 23% more effective than non-tilted units. The Wartsila steerable thrusters feature a modern electric steering system to provide higher redundancy, reliability and a lower lifecycle cost.”

The solutions are slated to be delivered to the yard during the first half of next year, while the vessel is expected to be delivered during Q2 2023.

Last week, Wartsila secured orders to deliver steerable and tunnel thrusters for two new WTIV that are under construction for China Three Gorges Corporation, a China state-owned power firm.
