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’s team are very focused in their approach to provide a high-quality product and service. We are looking forward to working with them in the future.”
