C.S. Sovereign is a multi-role DPS-2 vessel capable of undertaking both cable maintenance and installation projects. Her open deck enables her to deploy a variety of subsea vehicles and her powered turntables make her the ideal solution for a diverse range of offshore engineering activities. C.S. Sovereign is primarily committed to serving ACMA, the Atlantic Cable Maintenance Agreement, and is based in Portland, UK.
C.S. Sovereign has been involved in many projects as well as being used as a charter vessel. Her accomplishments include: installation and burial of 30km of inter platform cable on the Fibre to Judy project in 2010 and completing the main lay installation operation, utilising the Atlas ROV and Cable Plough on the ValHall Clyde project.
