Emergency Vessel Attachment & Towing System (EVATS)

Samson’s EVATS provide a significantly safer, rapidly deployed, more efficient method of connection for towing disabled ships. EVATS is designed to have near-universal compatibility with ships mooring gear arrangements with multiple attachment points on the disabled ship. In addition, it enables the rescue vessel to maintain safer distances from the disabled ship. EVATS can be deployed from the ship’s deck, helicopter or rescue vessel.

300MT EVATS Components:

  • The Towing Bridle, constructed of Samson Quantum-X™, leads through the centerline chock on the disabled ship and attaches to multiple deck fittings. Engineered for improved snag resistance and high coefficient of friction, Quantum-X offers enhanced grip on bitts and chocks. Chafe protection provides increased security on key contact points.
  • The Hawser bushing is sized to fit through most chocks and provides a secure, non-abrasive connection between the bridle to the towing hawser. Made of marine-grade aluminum, it is easy to handle and incorporates optimized line bend ratios. The bushing allows the bridle legs to share towing loads equally, even when rigged asymmetrically.
  • The Towing Hawser constructed of AmSteel®-Blue combines the extreme strength with ease of handling and positive buoyancy. Tubular line floats are added to ensure the composite thimble remains readily recoverable at the water’s surface
  • The retrieving line incorporates a pilot anchor to stream the hawser to windward when deployed from the disabled ship. This allows the rescue vessel to stand off while retrieving the tow system rather than attempting close maneuvers. Additional floats and a strobing beacon make it visible in darkness or periods of low visibility.

Vulcan: Emergency Tow-off Pendant (ETOPS)

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. Wire rope is often used in this application; however, the handling of these heavy wire ropes has resulted in many injuries to deckhands. Samson’s synthetic alternative called Vulcan, is significantly lighter and eliminates “fishhooks,” broken wires that protrude from the wire rope that result in hand injuries. Maintenance costs are also reduced when using synthetic ropes in comparison with wire ropes.

Vulcan ETOPS

Since no testing standards or high heat performance requirements exist, Samson has developed a set of testing parameters by which to compare Vulcan to wire. Table 1 provides a comparison between wire and Vulcan with regard to the OCIMF minimum breaking strength requirements. The patented synthetic ETOP Vulcan is made of Technora® fiber in conjunction with a proprietary fire-resistant coating that meets the OCIMF required breaking strength after exposure to flames and a high-temperature environment.


Vulcan


Because some strength is lost when Vulcan is exposed to high temperatures, the user may choose to use a larger diameter so that its retained strength still meets the required break strengths even when operating under severe heat or flame conditions. Table 2 represents the rope sizes that meet the OCIMF strength requirements. Ropes at these sizes were tested at 575°F (300°C) after being held at 20% of their break strengths for 30 minutes at the same temperature. Note that the wire sizes are larger here than in Table 1. This is due to the strength loss that is also observed in wire when exposed to the same high-temperature testing parameters as the synthetic rope.
