Offshore support vessels

Offshore support vessels

Certified multi-hazard protection for offshore support vessels. Offshore support vessels are the backbone of offshore energy operations, transporting crews, equipment and supplies to platforms in some of the harshest marine environments. These vessels face constant vibration, saltwater exposure, heavy loads and extreme weather, all of which place high demands on safety-critical penetrations throughout the ship.

Designed for offshore support vessels

CSD’s certified sealing systems are trusted across global offshore support fleets to deliver long-term protection against fire, water, gas, smoke and electromagnetic pulse (EMP). Our solutions help operators maintain vessel integrity, protect crew and equipment, and meet stringent offshore regulatory standards, whether for new builds, conversions or life-extension programmes.

“CSD Technical Services delivered the water, and gastight sealing works to a high standard across our control room and DNO substation. Their support contributed effectively to our wider climate action plan, including the installation of a new solar farm and battery storage system. We were very satisfied with the work and will be considering CSD for future projects.”
