Offshore Wind Power Foundation Structures

We will leverage the engineering and
welding techniques developed through our shipbuilding business,
as well as our vast factory space and well-equipped facilities,
to manufacture the foundation structures for offshore wind power generation.

Surrounded by the sea on all sides, Japan has the world's sixth largest EEZ, and floating offshore wind power generation is attracting attention as a measure for achieving a decarbonised society.
We will contribute to the development of offshore wind power generation by applying the technology and knowledge we have cultivated over many years in the shipbuilding business to the manufacture of the foundation structures of floating offshore wind power generation.

In recent years, there has been a trend towards larger wind turbines, and it is expected that the size of the foundation structures will also increase accordingly.
We are able to manufacture both floating and fixed foundation structures using our large dock and Goliath crane.

Engineering

There are several different types of structure and mooring system for the foundation structure of floating offshore wind power generation, and the most suitable one will differ depending on the power generation project envisaged.
We will contribute to the verification of the feasibility of the project by considering the optimisation of production design and manufacturing according to the type of floating structure chosen by the customer.
We will also help to improve the feasibility of the project by considering shipping and transport.

Manufacturing

The welding and canning technologies developed in the shipbuilding industry can be applied to the manufacture of the foundation structures of floating offshore wind power generation.
In addition, the manufacturing of cylindrical structures, which are not often used in the shipbuilding industry, will be strengthened through collaboration with Sumitomo Heavy Industries Process Equipment Co., Ltd.
Furthermore, the entire Sumitomo Heavy Industries Group will work together to establish a high-speed mass production system, combining the Toyota Production System and large-scale coating facilities.

Utilisation of large dock

The Yokosuka Shipyard is strategically located in Tokyo Bay, boasting one of the largest docks in eastern Japan.
The dock spans 560 metres in length and 80 metres in width, equipped with two Goliath cranes, enabling the shipyard to undertake the production of large-scale foundation structures.
The completed foundation structures are shipped out by being floated out and launched from the dock, or by being lifted out by a floating crane barge.
