A recent partnership between Sembcorp Marine and GE aims realize one of the most challenging offshore projects in recent times for Heerema’s new Semi-Submersible Crane Vessel (SSCV) Sleipnir, which at 220 meters long and 102 meters wide, will be the world’s largest crane vessel.

 
Equipped with two cranes, each boasting a lifting capacity of 10,000 tons, Sleipnir will be used for offshore construction and heavy lifting.
 
A recent deal signed between GE’s Marine Solutions business and Sembcorp Marine will see GE provide technology that will be at the heart of the operations of the new SSCV Sleipnir, including the electrical part of the power and propulsion system which includes 12 sets of 8-megawatt (MW) generators, eight units of 5.5-MW propulsion motors, medium-voltage switchboards, transformers and MV7000 drives. The power generated from the system will position and propel the vessel and provide electricity to the vessel’s onboard systems. 
 
GE said its solution for the SSCV Sleipnir has been conceived from the ground up in order to overcome various technical challenges and meet requirements specific to this project. The entire power system is designed for fault tolerance in accordance with Lloyds Register’s Rules (DP AAA). While being 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. According to GE, together, these measures result in a compact, yet highly sophisticated solution, which facilitates operations while helping to minimize downtime and increase availability.
 
GE leveraged its widespread diverse supply chain to source its scope of supply for this project, with the generators, switchboards, motors and variable frequency drives being sourced from various countries in Europe. The delivery plan of GE’s scope of supply is spread between September 2016 and May 2017, with the vessel scheduled to be commissioned by December 2018.
