VULCAN

Emergency tow-off pendants (ETOPs), commonly referred to as “fire wires,” provide a means of towing the ship away from the dock in the event of a fire. Samson developed Vulcan, a synthetic alternative to traditional wire ropes (fire wires). Vulcan is significantly lighter and eliminates “fish hooks,” which are broken wires that protrude from the wire and result in hand injuries. Maintenance costs are also reduced when using synthetic ropes in comparison with wire ropes. The patented synthetic ETOP Vulcan is made of Technora® fiber in conjunction with a proprietary fire-resistant coating the meets the OCIMF-required breaking strength after exposure to flames and a high-temperature environment.
