Is your passive fire/flood protection system too passive? Cable & Pipe penetration sealing systems are designed to keep fire, toxic gasses, and flooding in the space they originated in, allowing the vessels crew the time to safely extinguish, de-gas or dewater that space. These systems are all required to meet maritime rules and standards under the jurisdiction set forth by IMO and SOLAS. Meeting these requirements is mandatory, but many of the systems out there meet only the very basic requirements. Because of the lifesaving/ship saving importance of penetration sealing systems, just meeting the minimum requirements is not enough; consideration should also be given to the following:

  • Does the system have proof (tests) of longevity (performance should last the lifetime of the vessel)?

  • Does the system mechanically support the cables or pipe within the transit (sagging occurs over time without mechanical support causing failure of the seal)?

  • Can the system corrode the interior of the conduit attract & hold moisture)?

  • Can the system crush fiber optics cables over time, causing other important system failures?

  • Is the system "active" under fire – will it compensate for missing cables, gaps in the seal, or cable jackets that have burned away?

The main point is, will the passive fire/flood protection system you decided to install on your vessel work 5, 10, 22 years from now at 3:15 AM when a fire or flooding breaks out? The ship's crews' lives depend on it.
