SEVEN-THRUSTER ORDER FOR EFFICIENT WTIV PROPULSION

SEVEN-THRUSTER ORDER FOR EFFICIENT WTIV PROPULSION

Wednesday, December 8, 2021 

Wärtsilä is to supply seven thrusters for a new Wind Turbine Installation Vessel (WTIV) being built at the Daewoo Shipbuilding & Marine yard in South Korea for Eneti Inc.

Wärtsilä says the thrusters will enable optimal propulsion performance for the vessel. There is an option for a second vessel.

The order includes six Wärtsilä WST-32 thrusters fitted with electric steering system for a lower lifecycle cost, reliability, and reduced energy consumption, and one Wärtsilä WTT-36 thruster All seven comply with applicable environmental regulations with the use of Environmentally Acceptable Lubricants (EAL), and are scheduled for delivery to the yard during the first quarter of 2023. The vessel is expected to be delivered to the owner in the latter part of 2024.

The next-generation vessel features a Gusto 16000X design and will have advanced lifting capabilities and high energy efficiency. Wärtsilä’s advanced lightweight thruster configuration meets the design parameters’ performance standards.  Wärtsilä’s retraction system combined with an energy efficient 8-degree tilt are key factors in the thrusters’ station-keeping performance. The tilt is believed to deliver up to 23% percent higher effective thrust than non-tilted thrusters, while reducing the power requirement and fuel consumption. The retractable thrusters have a combined electric steering and retraction system which saves space and weight, and which has fewer components for greater reliability.

Min Yun, head of DSME Offshore Machinery Procurement, said: "We are very familiar with the quality and efficiency of Wärtsilä’s thrusters. They can be trusted to ensure performance in all sea conditions, which is essential in a vessel of this type.”

Eneti Chairman and CEO, Emanuele A. Lauro, said: “In line with our commitment to environmental sustainability, our focus today is on highly efficient technologies capable of delivering excellent performance. We are assured that the Wärtsilä solutions meet this requirement.”

Roger Holm, President Marine Power and EVP Wärtsilä Corporation, added: “Safety and reliability are central needs for modern jack-up WTIVs, and our thruster package is optimised to deliver them. Furthermore, by ensuring efficient free sailing and outstanding dynamic positioning, regardless of the sea conditions, we are contributing to the decarbonisation of the maritime sector.”

This is the fourth WTIV with Wärtsilä thrusters contracted during 2021.
