The HOS#317, an 82-meter LOA Offshore Construction, Diving Support, and Accommodation Vessel, is a versatile and multi-purpose asset built in 1983 and later converted in 2000 by the renowned Ulstein Verft in Norway. It has a rich operational history across various offshore sectors, including Walk-to-Work, ROV support, and both saturation and air diving operations. Additionally, the vessel has been deployed in multiple global survey and subsea projects, making it a proven and reliable platform for complex offshore undertakings.
This vessel is classified as a DP2 Offshore Support Vessel, equipped with the Kongsberg SDP 21 Dynamic Positioning System**, allowing for precise station-keeping even in challenging sea conditions. The DP2 system is backed by advanced reference systems, including three DGPS, a Taut Wire, and a Kongsberg HiPAP system, ensuring reliability during offshore operations.
At 80.77 meters in length with a breadth moulded of 18 meters and a summer draft of 4.97 meters, the vessel is robust and designed for versatility. It boasts a deadweight of 2,490 tons and a gross tonnage of 3,349 tons, providing significant deck space and stability for multiple offshore applications. The cargo deck area spans 550 square meters, with a deck strength of 5 tons per square meter, enabling it to support heavy equipment and cargo with ease.
The vessel’s power is driven by two MAK 8M 453 main engines, each generating 3,000 BHP, for a combined output of 6,000 BHP. These engines drive twin controllable pitch propellers (CPP), providing enhanced maneuverability, while the vessel is further stabilized by two Ulstein bow thrusters and two stern thrusters, each rated at 800 BHP. In addition, the vessel is equipped with two main alternators of 1,140 kW each, and two shaft generators also providing 1,140 kW of electrical power, with an emergency generator rated at 89 kW to ensure continuous operations in case of power failure.
Designed for heavy lifting and subsea tasks, the vessel features a 50-ton active heave compensated (AHC) crane from TTS Nordlift, fitted with a 54mm wire, suitable for offshore wind turbine operations and other subsea interventions. The vessel is also equipped with standard loading gear, including an anchor windlass and two capstans, enhancing its versatility during mooring and anchor handling operations.
The accommodation capacity includes 68 berths, with an option to expand to 80 berths and a hospital facility. There are 34 cabins designated for up to 50 clients, while 12 cabins are allocated for 16-18 marine crew. The accommodation facilities are well-appointed with two lounges, a cinema, client offices, a conference room, and a sauna, ensuring comfort during long offshore projects.
Additional features include a moon pool, ROV hanger, and a Walk-to-Work system, making the vessel ideal for a wide range of subsea and offshore construction operations. The vessel also has a reverse osmosis fresh water generation system, enabling it to support extended offshore missions without relying on external fresh water supplies.
