Surface Effect Ship Designed for Crew Transfer Vessels

ESNA and Strategic Marine have entered into an agreement to develop a Surface Effect Ship Crew Transfer Vessel (SES CTV) for offshore wind applications. This vessel type combines the benefits of higher speed, increased operational wave height, and reduced fuel oil consumption. The plan is to begin construction of the first offshore windfarm SES CTV in the fourth quarter of 2024, building on the parties’ previous experience in collaborating on SES crew boats for oil and gas projects.

The agreement also includes plans for increased collaboration between ESNA and Strategic Marine to promote SES technology in various markets, such as offshore wind, oil and gas, and security and defense applications. Strategic Marine has a strong track record in building CTVs for offshore wind, with 36 vessels delivered since 2012, while ESNA brings over 40 years of experience in designing, building, and operating SES vessels.

The SES concept offers competitive advantages such as high speed for shorter transit times, improved seakeeping and passenger comfort, and fuel savings with reduced emissions. ESNA will provide the vessel design package and equipment package for the main SES systems, simplifying construction with modular electrical systems and enhancing energy efficiency and operational performance with a modern control system. This collaboration aims to advance SES technology in the offshore wind industry and beyond.
