Siemens Collaborates On Jacking System For Offshore Applications

Posted on January 14, 2010

Siemens Netherlands and GustoMSC, a subsidiary of the Dutch company SBM Offshore, have signed a strategic partnership for the use of electrically powered rack and pinion systems for jack-up units in the offshore industry. The variable-speed-driven systems, developed jointly by GustoMSC and Siemens Netherlands, are used to lift drilling vessels and platforms above sea level at their work location, making them impervious to waves.

According to the company, these frequency-controlled electrical drives can position the legs of the drilling vessel or platform on the sea bed faster and more accurately, than conventional systems. This also renders faster commissioning, easier operation and service with remote control access and condition monitoring.

The Siemens scope of supply is the electrical system, including Sinamics S120 drives, Simantic S7 control, PCS7 and motors. These electrical jacking systems are already in use on two platforms in the North Sea. The company reports they have received 13 follow-up orders.

GustoMSC and Siemens foresee opportunities to utilize this system on wind turbine installation vessels for installing offshore wind farms.
