Published on

CSD Sealing Systems provide the most advanced and reliable solutions to firetight, gastight and watertight sealing of cable and pipe entries in offshore applications. CSD Sealing systems meet the European Council Directive 96/98 EC on marine equipment and are covered by EC (MED) certificates issued by DNV.

Typical Offshore Cable & Pipe Sealing Applications
*Penetrating fire boundaries
*Penetrating water-tight and gas-tight boundaries
*Penetrating A0/H0 bulkheads
*Penetrating smoke-tight boundaries
*Adding new water-tight and fire-tight boundaries
*Running new cables/pipes during service life
*Pipes corroding within penetrations
*Penetrating external hull

CSD Sealing Systems are tested by Lloyds Register and DNV - providing effective performance against the spread of fire, gases or water in offshore environments.

  2. 2. INTRODUCTION The RISE Multi-Cable and Pipe Transit Sealing System provides an effective and simple solution to all fire, gas and watertight duct sealing requirements. It consists of only 2 components: rubber insert sleeves and FIWA (or NOFIRNO) sealant; a silicone based, fire-resistant, water-repellent sealant. This makes the system quick and easy to install. BENEFITS • Cost effective • Few components • Up to 4 hours fire protection • No frame required • High levels of gas and watertightness • Suitable for trefoil cables • Ensures DSEAR compliance • WIMES compliant • Ease of re-entry for adding cables • Resistant to submersion in petrol, diesel and transformer oils • Quick and easy to install • Resistant to methane, hydrogen sulphide and chlorine • Complies with ATEX regulations • Age tested to 50 years
  3. 3. TECHNICAL DATA Water and Gas-Tight Flexible and Versatile The elasticity and high bonding strength of the FIWA or NOFIRNO sealant offers a flexible seal, which resists movement, shock and vibration, as well as high pressure. The RISE rubber insert sleeves are applied to ensure long-term cable separation and a backing for the application of the sealant. For water and gas-tight applications our standard 60mm RISE sleeve is sufficient. The RISE system can be used in vertical as well as horizontal ducts. The insert sleeves cling to the cables without sliding down and falling out of the penetration. The high adhesion and viscosity of the sealant means it will not run or drip when applied overhead. Fire, Water and Gas-Tight Installing additional cables is very straightforward. It is a simple matter of coring into the soft rubber layer of the sealant to a depth of 20mm and passing the additional cables through the opening created. The sealant is then applied around the new cable to re-seal. No need to disassemble the whole transit. Using the type FRR/LEHF RISE insert sleeves at a length of 160mm and applying sealant to both faces of the opening provides a firetight seal. When exposed to heat or flame, the system expands around 10 times its original volume, creating a rubber mass surrounding the cables within the penetration. This assures total conduit sealing protection against fire, heat, toxic and corrosive gases.

  4. 4. INSTALLATION INSTRUCTIONS 1. Thoroughly clean the inside of the duct and cables, use an appropriate degreaser to remove the dirt, dust or oil to allow the sealant to bond. Apply a RISE insert sleeve of the relevant diameter around each cable. 4. Using a damp cloth, press the sealant down and between the cables. Ensure a sufficient amount of sealant is applied and it makes good contact with all surfaces. TOOLS REQUIRED: (INSTALLATION KITS AVAILABLE) • High ratio sealant gun • Tape measure • Disposable nitrile gloves 2. Fill the remaining free space with spare RISE insert sleeves, usually of sizes 27/19 and 18/12. Pack sleeves tightly then adjust to allow a 20mm gap from the front of the transit. 3. Apply a 20mm layer of sealant to the face of the transit. Begin in the most difficult area and work outwards. A slight overfill is recommended. 5. Using your hand (nitrile gloves are recommended), make sure enough sealant is between the cables and has been applied to the required depth and then smooth to finish. Wet the hands to prevent the sealant sticking. 6. Take a final check with a torch to ensure sufficient sealant has been applied between the cables. Sealant layer cures on average at a rate of 2mm per day. • Cloths • Long nose pliers • Water spray • Wooden depth gauge • Wire brush • Degreasing agent
