Friede & Goldman and OIM Wind Launch Innovative FO-146 Wind Turbine Installation Vessel for US and Global Market

Veteran engineering and naval architecture firm Friede & Goldman (F&G) and OIM Wind Ltd are proud to announce the FO-146 Wind Turbine Installation Vessel (WTIV). The FO-146 is based on F&G’s WindSetter Class WTIVs.  It combines the industry’s latest technology and innovative solutions to meet the evolving needs of the global offshore wind market.

The FO-146 WTIV is the result of a collaboration between Friede & Goldman and OIM Wind, leveraging their expertise and decades of experience in the offshore industry. With a shared commitment to delivering superior value for money and addressing the challenges of the wind market, the companies have developed a vessel that offers unparalleled performance, efficiency, and versatility.



The efficient-sized hull can accommodate up to five x 18MW or four x 20MW WTG sets, including their Full Height Towers on its main deck. It has an impressive water depth capacity of 80m and with a state-of-the-art 3200t SWL leg encircling crane, has the reach and capacity to install XXL foundations exceeding 3000t.

“We are thrilled to introduce the FO-146 WTIV, a game-changing and “Green” solution that addresses the evolving demands of the offshore wind industry,” said Robert Clague, P.E., VP -Engineering of Friede & Goldman. “Our collaboration with OIM Wind has been instrumental in bringing this innovative design to fruition, combining our expertise and shared vision to deliver a vessel that sets new standards in performance and efficiency.”

Through our partnership with Friede & Goldman, we have created a vessel that not only meets the needs of the “future” global offshore wind market but also offers superior value for money to our clients. We are proud to be part of this remarkable achievement.”

The FO-146 WTIV design has already generated significant industry interest with many offshore ongoing tender solicitations, and plans are underway for the construction of at least two units to meet growing demand in both the United States and Global offshore markets.
