Seatrium has announced the successful delivery of the next-generation Wind Turbine Installation Vessel (“WTIV”), which was handed over to its customer, Maersk Offshore Wind (“MOW”), on 26 February 2026. This milestone follows the successful completion of sea trial activities and final readiness evaluations at the Group’s flagship Tuas Boulevard Yard. This also marks a significant achievement for Seatrium and underscores the Group’s growing contribution to advancing the global offshore wind industry. 

Mr William Gu, Executive Vice President, Seatrium Energy (Marketing), said, 
“This state-of-the-art WTIV represents a major step forward in pushing the possibilities for global offshore wind. We are proud to deliver this unique vessel to our partner, Maersk Offshore Wind, to advance the progress of the end customer’s wind farm development. This achievement not only underscores Seatrium’s engineering capabilities, it also reinforces the critical role we play in building the backbone to global offshore wind systems. As the world scales renewable energy at unprecedented speed, we remain dedicated to delivering innovative, future-ready solutions that drive the next generation of offshore wind development.” 

Custom-engineered and built by Seatrium to install some of the world’s largest offshore wind turbines, this first-of-its-kind WTIV sets a new benchmark for global offshore wind installation capability. The milestone marks the completion of an extensive construction programme involving the installation of a 1,900-tonne main crane, precision heavy-lift operations, full system integration, and rigorous validation by leading international classification societies. With a 180-metre hook height, the crane supports the installation of 15+MW-class turbines.  

The vessel’s feeder-based installation design enhances operational efficiency, enabled by a stabilising system to hold feeder vessels for the transfer of offshore wind components, even in high sea states. This improves installation efficiency by extending the operational weather window, ensuring the WTIV can carry out uninterrupted installations, improving operational efficiency and reducing total cost and time of installation. This feeder-based installation solution is US Jones Act compliant and can also be deployed in other geographies. The WTIV is due to sail in March 2026 for its first assignment at the Empire Wind project offshore New York, where it will play a pivotal role in advancing the wind farm’s mission to deliver clean and reliable energy to 500,000 homes(1). 

Throughout the project, Seatrium upheld its steadfast commitment to safety, achieving zero Lost Time Injuries (LTIs) - a testament to the Group’s strong safety culture and disciplined project execution. 

As Seatrium continues to expand its offshore wind portfolio – ranging from offshore substations and floating foundations to zero-emission vessels and specialised installation assets such as WTIVs – each achievement represents another step forward in supporting the industry’s rapid growth, solidifying Seatrium’s role as a key enabler of global net-zero ambitions and a trusted partner in driving the future of offshore wind.
