GE Technology powers largest crane vessel

At 220m long and 102m wide, Sleipnir is the world’s largest crane vessel, with two 10,000 tonne revolving cranes. To enable smooth operations GE was chosen to provide the electrical aspect of the power and propulsion system including 12 sets of 8MW generators, eight units of 5.5MW propulsion motors, medium-voltage switchboards, transformers, MV7000 drives and the Visor remote monitoring and diagnostics system.

“In addition to the long-term electrical expertise we have in the offshore industry, one of our key strengths lies in our capability of system integration which allows us to create more efficient systems, deliver additional value to our customers and help them maintain fleets with long-term technological advantage and competitiveness in the industry,” said Andy Cooper, managing director, GE’s power conversion business UK.

Sleipnir is the world’s first crane vessel with dual-fuel engines running on either marine gas oil or LNG. The entire power system is designed for fault tolerance in accordance with Lloyd’s Register’s Rules and Regulations (DP AAA).

More compact than standard solutions, GE’s solution has advanced sensors built in to help operators monitor the health of each piece of equipment in real time and signal possible malfunctions.
