World's Largest Class, Jack-Up Vessel for a Renewable Future

Offshore wind farms are a highly promising form of renewable energy from the viewpoint of power generation capacity and stability. Shimizu Corporation is building a Jack-Up Vessel to help Japan expand its wind energy sector. The vessel will have one of the largest loading capacity in the world. It will be capable of installing mega-turbines with a 14–15MW capacity. To strengthen the company's position in offshore wind energy, Shimizu Corporation has teamed up with industry leaders Fred. Olsen and Heerema Marine Contractors.

1.World’s Largest Class Loading Capacity

The vessel will be 50m wide and 142m long, with a gross tonnage of 28,000. With its large loading capacity, the vessel will be able to load and install a large quantity of components in one trip, thereby streamlining the installation process. Specifically, it will be able to load all the components for seven 8MW turbines or three 12MW turbines.*
*Calculated on a per-project basis, using seismic assessment and other metrics

2.World Class Performance

The crane will have a maximum lifting capacity of 2,500 tons and a maximum lifting height of 158m, enabling installation of the foundation, blade-nacelle assembly, and other components for 14–15MW turbines. The jack-up vessel is designed to withstand rough sea conditions, ensuring stable performance regardless of weather.
*It will be able to operate in depths of 10 to 50m.

3.Speedy Installation Process

Like many European-built Jack-Up Vessel, Shimizu's vessel is self-propelled, which eliminates the need for towing and thus speeds up the installation process.
