Østensjø Unveils Innovative Ocean Energy Support Vessel for Offshore Operations

Norwegian offshore support company Østensjø has commissioned the construction of a new concept offshore support vessel, known as an Ocean Energy Support Vessel (OESV), at the Astilleros Gondan shipyard in Spain. This innovative design aims to enhance versatility for a wide range of offshore support tasks, marking a significant advancement in Østensjø’s ongoing efforts to modernize and improve its fleet. CEO Kristian Helland Vea emphasizes the vessel’s adaptability to meet current and future market needs, ensuring relevance in various ocean activities for years to come.

The OESV will be equipped to conduct diverse operations within the offshore energy sector, including inspection, maintenance, repair, construction, walk-to-work/flotel services, and cable laying. Designed by Salt Ship Design in Norway, the vessel will be 120 meters long with a beam of 23 meters, offering accommodation for up to 180 individuals in high-standard cabins. The focus on operational efficiency and flexibility across different ocean segments underscores the vessel’s versatility and adaptability for various tasks.

One of the key features of the new OESV is its commitment to environmentally friendly operations without compromising performance. The vessel will utilize a battery power hybrid propulsion system and other energy-saving technologies like heat recovery systems to significantly reduce greenhouse gas emissions. Additionally, the design is prepared to incorporate low-carbon technology in the future, highlighting Østensjø’s commitment to sustainable practices. The vessel is expected to be delivered in the second half of 2027, adding to Østensjø’s fleet of 29 vessels that cater to offshore wind, towage, offshore oil and gas, and offshore accommodation services for the global offshore energy markets.
