JULY 13, 2016 —   GE's Marine Solutions business is to provide a high-voltage system to power and propel the world's largest semi-submersible crane vessel (SSCV), Sleipnir, currently under construction at the Sembcorp Marine Tuas Boulevard Shipyard in Singapore,

The 220 m long and 102 m wide Sleipnir]will be equipped with two cranes, each with a lifting capacity of 10,000 tons, and will be used for offshore construction and heavy lifting.

GE is to provide the electrical part of the power and propulsion system including twelve 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.

The solution provided by GE has been conceived from the ground up to meet requirements specific to this project. As a result, the entire power system is designed for fault tolerance in accordance with Lloyds Register Rules (DP AAA).  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. Together, says GE, these measures result in a compact, yet highly sophisticated solution that facilitates operations while helping to minimize downtime and increase availability.

"To power our newest SSCV, we wanted to collaborate with some of the best in business," said Martijn Wijdeveld, senior project manager, Heerema Offshore Services. "In GE, we have found a partner that brings considerable experience and know-how into the project. We're confident that their technology onboard our vessel will facilitate reliable operations."

William Gu Wei Guang, head of Sembcorp Marine Rigs & Floaters, said, "To build this mammoth vessel for Heerema, we're happy to be partnering with GE. We look forward to working with GE in installing high-quality and best-in-class solutions onboard the vessel."

"We're excited to be working on this project with Heerema," said Tim Schweikert, president & CEO, GE's Marine Solutions business. "Building a SSCV of such proportions comes with its own set of challenges. With our deep technical expertise, we're confident of tackling these challenges and delivering a high-quality solution to enable flawless operations of the vessel. We also believe that this project will strengthen the relationship between GE, Heerema and Sembcorp Marine."
