Bosch Rexroth to Give Japanese Jack-Up a Lift

Bosch Rexroth has received an order from GustoMSC to engineer, manufacture and commission a drive and control system for GustoMSC's continuous jacking system (CJS) to be installed on a Japanese wind turbine installation vessel (WTIV).  

The CJS lifts the vessel out of the water in one motion, turning it into a stable offshore construction platform, Bosch Rexroth said.

The system will supposedly be installed on the first WTIV to be built in Japan. The vessel was ordered by Penta-Ocean Construction and is currently being constructed by Japan Marine United Corporation (JMU).

In addition to designing and supplying the complete jacking system, GustoMSC is also responsible for the basic design of the jack-up vessel which will reportedly be able to install wind turbines on the seabed in a single day under normal weather and sea conditions.

The vessel is designed based on jack-ups used in Europe for installation of oil rigs or offshore wind turbines, but with a jack-up system that matches Japanese natural conditions and on-site characteristics.

It will be equipped with a fully-revolving Huisman crane with an 800-ton lifting capacity, as well as a dynamic positioning system, enabling the vessel to perform installation of large-scale marine structures such as offshore wind turbines with a capacity of up to 6MW and foundations in the water depths of up to 50 metres.

The jack-up is also designed for operations in Japan’s Greater Coasting Area and for becoming a shallower draft vessel. It will come equipped with accommodation units and a helicopter deck for emergency transfers.

The vessel is expected to be delivered in September 2018.
