With an increasing interest in renewable energy around the world, Japan is willing to contribute to progressive countries which promote the offshore wind power electricity generation. Japan's Shimizu Corporation seeks to increase offshore wind power construction capacity by building an offshore wind farm construction vessel. Shimizu Corporation's announcement of the construction comes after Japan passed a law earlier this year to increase offshore wind power development. The sea vessel will have four legs that can be lowered to the ocean floor, lifting the rig above the water surface. The elevated platform will allow a stable work area so that cranes can operate without interruption from the surrounding water conditions. The construction vessel will be capable of building the extra-large 8 and 12-megawatt wind turbines. Japan and many countries are expected to rapidly grow offshore wind power over the next decade. Shimizu Corporation expects business opportunity all over the world.
