Penta-Ocean Construction Co Ltd, Kajima Corp and Yorigami Maritime Construction Co Ltd (Kobe City) announced Nov 20, 2019, that they will jointly build an SEP (self-elevating platform)-type multi-purpose crane ship for construction of wind farms.
The ship is equipped with a fully-turning crane with a maximum load of 1,600t for large-scale wind farms. It can be used for efficiently constructing the foundations and wind turbines of 10-12MW offshore wind power plants anchored to the seabed.
By jacking up the hull of the ship, it becomes possible to carry out crane operation with a high safety, workability and accuracy even in sea areas with severe meteorological and hydrographic conditions. It also supports operation in deep water (water depth: 50m).
The crane ship has a large deck space and enough jack-up capability and can be mounted with and carry several wind turbines with a capacity of 10-12MW each. With a dynamic positioning system (DPS) that keeps the position of the hull of the ship, it becomes possible to shorten positioning time at the time of jacking up the hull.
The Netherlands-based GustoMSC, which deals with more than 70% of SEP ships in the world, made the basic design of the ship. Also, Singapore-based PaxOcean Engineering, which is affiliated with Kuok Family (Malaysia's largest international conglomerate), is responsible for the construction of the ship. The main crane of the ship is a product of the Netherlands-based Huisman, a leading manufacturer of offshore cranes.
