Submarines

Sealing systems engineered for extreme pressure and precision. Submarines demand the highest level of engineering integrity, where every seal contributes directly to vessel safety, performance and mission success. CSD’s sealing systems are trusted across naval fleets to deliver certified protection against fire, water, gas, smoke and electromagnetic pulse (EMP), ensuring complete compartment integrity at depth.

Designed for submarine demands

Built to perform under immense pressure and constant vibration, our systems are corrosion-resistant, maintenance-free and fully compliant with the rigorous standards of submarine construction. Designed for long service life and operational reliability, CSD solutions help protect critical systems and crew in the most unforgiving environments on earth.
Our Case Studies

High-pressure watertight and gastight integrity – tested up to 10 bar and beyond

Certified fire resistance (A-0 to A-60 rated) for compartment safety

EMP and EMC shielding for control, communication and navigation systems

Corrosion- and vibration-resistant materials for submerged operation

Maintenance-free and re-enterable systems with proven 50+ year service life

“The service provided by CSD was excellent in all aspects. The installation crew were skilled, hard-working and resourceful and also integrated well with our own men who supported then with the external duct sealing.”
