CSD’s marine transit frames are designed to integrate seamlessly with NOFIRNO®, RISE® and SLIPSIL® systems, ensuring reliable fire, water and gas protection for grouped cable penetrations. Manufactured from high-grade materials and certified to international standards, they are trusted across naval fleets, commercial shipping and offshore platforms.

Multi-cable Transit Frames – Marine
Engineered frames for harsh marine environments. In marine and offshore environments, sealing systems face some of the toughest conditions – constant vibration, pressure fluctuations, saltwater exposure, and strict safety requirements. Multi-Cable Transit (MCT) frames provide the robust structural support needed to house sealing systems in bulkheads, decks, and other critical areas.

“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.”
