Flexibility for naval supply ships

Flexibility for naval supply ships

Roxtec seals for cables, metal pipes and plastic pipes were beneficial in the retrofit of the Danish military support ships in the Absalon class.

Saving time and money

Significant savings were achieved thanks to the flexible modular-based seals. They can be opened, resealed, and are easy to adapt to cables of different sizes. Unused modules in a Roxtec seal still serve as spare capacity. This built-in feature also saves time and money for the naval bases and the Royal Danish Navy. There are 2,400 openings for cables and 1,200 openings for pipes onboard, and the cables and pipes to the equipment are routed through EMC zones and hazardous areas. 

Reasons for choosing Roxtec

  • Adaptable and reusable sealing modules with Multidiameter™, the Roxtec solution based on modules with removable layers, that save up to 70,000 euros per ship
  • Future included capacity for retrofit additions
  • Significant time-savings of up to 1 hour per individual installation
  • Local support
  • Certified protection: fire protection A-60, water pressure 4 bar, ABC warfare
