GE's Power Conversion business is to supply of dynamic positioning (DP) for a floating accommodation unit being built by Cosco (Nantong) Shipyard in Nantong City, China.
The vessel is being built for Logitel Offshore, the Singapore-based floating logistics and accommodation rig owner, which has a license agreement to use the proprietary Sevan Marine cylindrical design in the accomodation vessel market.
The complete project includes a C-Series Class 3 DP system and manual thruster control system.
Sevan Marine specializes in units with cylindrical hulls, but until now it has used the design only for floating production, storage and offloading (FPSO) units and deep water mobile offshore drilling units (MODU).
This is the first time that the Sevan design is used as a cylindrical accommodation vessel. Sevan hulls are suitable for operation in water depths of more than 3000m, and the units are designed to operate in extreme conditions.
The DP system for the new accommodation vessel complies with DNV’s DYNPOS-AUTRO notation, which means it has a very high level of design redundancy featuring, for example, an alternate backup control position in addition to the primary control position.
GE units in China, Norway and the UK are working on the project.
The control systems will be delivered and integrated into the accommodation vessel in time for its delivery around the middle of 2014.
