Caley Ocean Systems Supplies Two 2,500Te Turntables for Global Marine Systems

Caley Ocean Systems has supplied two, large capacity, 2,500 tonne turntables to Global Marine Systems Ltd (GMSL) to handle deployment of non-coilable cables from their vessel CS Sovereign.

Caley has worked closely with GMSL, and their naval architects, to design the two turntables such that they can be built within the CS Sovereign’s existing cable tanks. CS Sovereign is a multi-role vessel capable of undertaking cable maintenance and installation projects for all types of submarine cable systems, principally in the Telecommunications & Energy industries.

The two, ‘basket’, turntables have open lattice outer walls, a closed hub and post positions for installing partitions, and are designed to operate at a maximum product linear speed of 1,000m/hr (at core). Caley has also supplied the loading arms and cable tracks required to control the cables required 4m minimum bend radius, along with all the system controls. To save time and cost, the turntables systems have been adapted by Caley to accommodate the vessel’s existing hydraulic power units (HPUs).

“CS Sovereign has an excellent reputation and a well earned track record on cable installation projects. The addition of these turntables further adds to the capability and flexibility of this vessel.” says Martin Hutchings, Special Projects, Global Marine Systems Ltd. “By adapting the turntable design for non-coilable cable, and where possible re-using existing control equipment, Caley Ocean Systems’, because of their experience with the design and build of large capacity turntables, has been an excellent partner in the development and successful installation of this equipment.”
