Recently delivered by the Japan Marine United (JMU) shipyard to Shimizu Corp., the GustoMSC designed and geared up offshore wind turbine set up vessel Blue Wind is Japan’s largest WTIV so far, and can allow Shimizu Corp. to effectively set up foundations and wind generators, helped by an progressive telescoping crane.
Shimizu Corp. chosen GustoMSC , a subsidiary of Houston-headquartered NOV Inc., to develop the large-capacity WTIV following a aggressive bidding course of in 2019. After intensive evaluations of the set up challenges offshore Japan, which embrace seasonal typhoons, earthquakes, and tsunamis, NOV proposed the GustoMSC SC-14000XL tailor-made jack-up design.
The WTIV design is particularly tailor-made to Shimizu’s necessities. The vessel is 142 meters lengthy, 50 meters broad, and might accommodate as much as 130 personnel. It can also be geared up with the well-proven GustoMSC variable pace rack and pinion jacking system.
NOV additionally delivered the world’s first totally built-in offshore telescoping leg encircling crane for the vessel. This permits the vessel to put in foundations and generators. When deployed in a retracted mode, the crane has a protected working load of two,500 tons with a lifting peak of 118 meters above the deck. Keeping the crane increase within the retracted mode with out an extension over the bow avoids crusing and maneuvering restrictions throughout transit and in port areas.
The telescoping crane can then simply transition to an prolonged mode to put in generators at a peak of as much as 158 meters above the deck and with a most protected working load of 1,250 tons. This innovation leads to a state-of-the-art, aggressive product for Shimizu’s massive offshore wind turbine initiatives.
