HVAC&R | Arendal Spirit

Our subsidiary Heinen & Hopman China has completed a remarkable project. Arendal Spirit is the world’s first semi-submersible cylindrical floating accommodation unit. Constructed in COSCO Nantong shipyard, the design of Arendal Spirit is based on Sevan Marine’s unique cylindrical hull. This provides several advantages compared with traditional accommodation vessels, including high uptime, excellent motion characteristics (less seasickness), more deck space, better stabilities and more storage spaces. Arendal Spirit was delivered to the owner Teekay in February 2015, now it is chartered to Petrobras, operating in the sea outside Campos Basin, Brazil.



Arendal Spirit’ main hull has a diameter of 60 meters, the main deck’s diameter is 66meters, the hull depth is 27 meters and the operating draft is 14 meters. It is equipped with DP3 Dynamic positioning system, 6 units of 5700kW full rotary propeller, and a 9 point anchor mooring positioning system.

A marine five star hotel

Arendal Spirit  features 500 beds in 248 cabins with en-suite bathrooms, windows, television, internet and telephone connections, lounge areas, coffee shop, public entertainment rooms, fitness rooms, dining rooms, office areas, meeting/conference room and cinema.
