Multi-cable transits
Modern marine and offshore environments rely on large volumes of power, data and communication cabling. Without proper sealing, multi-cable penetrations can become weak points, allowing fire, water or gas to spread and threatening both safety and operational continuity.
CSD’s sealing solutions are designed to handle complex, mixed-diameter cable bundles with ease. Our systems provide a re-enterable, maintenance-free barrier that ensures long-term safety and compliance, even under the toughest marine conditions.
Your Challenges
- Multiple cable types and sizes routed through a single opening
- Risk of fire spread through penetrations
- Exposure to saltwater, vibration and corrosive environments
- Requirement for re-entry to add, remove or upgrade services
Our Solutions
“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.”
