Early August Japanese construction conglomerate Shimizu Corporation ordered the construction of the GustoMSC SC-14000XL jack-up with an integrated Telescopic Leg Crane with the shipyard Japan Marine United. This unit will be the largest self-elevating platform for offshore wind installation to date in Japan and capable of installing wind turbines up to 12 MW.

This positions Shimizu Corporation as one of the key players in offshore wind installation in this region, as there is no vessel available that can cope with the installation of the larger turbines.

GustoMSC has worked with Shimizu Corporation on the design of the vessel, while Shimizu will work in cooperation with Fukada Salvage Construction on the operations management of the vessel. The JMU shipyard will carry out the construction of the unit with an expected delivery late 2022.

After the successful delivery of a GustoMSC-designed SEP by JMU earlier this year, we are very pleased to continue our business with JMU on this prominent new project for Shimizu Co. This SEP will be ready for installing the next generation wind turbines in the important and growing Japanese market as well as adjacent markets.

The telescopic leg crane

Key equipment on board is the GustoMSC Telescopic Leg Crane, offering an innovative combination of high hoisting capability for turbine installation and heavy load capability for foundation installation. The telescopic boom avoids protrusion of a very long crane boom outside the hull dimensions during transit, increasing transit conditions and manoeuvrability in ports.

The crane capacity for foundations sums up to 2,500 t at a height of 121 m, and wind turbine components can be installed at a staggering height of 161 m, with a maximum load of 1,250 t. With the right capacity at the right height this tool is future proof for the maintenance and installation of the new generation offshore WTG’s.

The SC-14000XL jack-up design

The GustoMSC SC-14000XL jack-up design is specifically tailored to Shimizu’s requirements. The vessel will be 142 m long, 50 m wide, and will have a total tonnage of 28,000 t and accommodate 130 persons. Besides the Telescopic Leg Crane, the unit will be equipped with the GustoMSC Rack & Pinion jacking system with a variable speed drive, a uniquely integrated piece of equipment, offering high performance, reliability, and safety.
