DEFENDER FUSE^TMSNAP-BACK SOLUTIONS

ADVANCED WARNING SYSTEMS

FORTIFY YOUR MOORING WITH DEFENDER FUSE™ FROM SAMSON ROPE - TRUSTED SOLUTIONS FOR UNYIELDING SAFETY & RELIABLE LOAD MANAGEMENT.

&amp;amp;nbsp;

Defender Fuse™ and Defender Fuse with Surge Arrestor™ are critical mooring safety devices designed to complement standard mooring systems. These devices are easily positioned between the mainline and tail or between the tail and on-shore connection. These systems are crucial for ensuring the integrity of mooring lines under high tension, significantly reducing the risk of serious safety concerns such as line failure and recoil. By offering a dependable early warning, Samson Rope’s Defender Fuse™ and Surge Arrestor technologies enhance overall mooring safety and protect your operations from line failure.

Defender Fuse consists of multiple types of rope, and once triggered, the load is transferred from the HMPE strength component to loops of a specially designed high-elongating material or “catch.” Developed to mitigate recoil situations before they occur, the catch material will continue to elongate until it reaches its final length, up to 150% more than its original, before complete rupture. In this way, the elongating material acts as an early warning system allowing the crew to take immediate action to reduce and manage your load effectively. When the Surge Arrestor option is included it will engage before full initial elongation and establish an additional ≥ 75% MBLsd connection.

THE ANATOMY OF DEFENDER FUSE SNAP BACK SOLUTIONS: CUSTOMIZABLE INTEGRATION FOR MOORING LINE SAFETY

Defender Fuses can be added to new or existing mooring systems. Designed to be positioned between the mooring line and tail or between the tail and on-shore mooring point and can accommodate common 11-meter and 22-meter tail configurations with mooring deployment lengths up to 100 meters. Custom units can be designed to your specific arrangement, ensuring seamless integration within your mooring line setup AmSteel-Blue is the HMPE strength component trigger. Designed to catch the mooring line and tail in an overload situation, the trigger deploys when a high load is applied.

The catch component is made of multiple loops of a high-elongation material that will continue to elongate up to 150% until complete rupture.

The eyes are protected by high-performance chafe protection with hook & loop closure.

Durable chafe protection protects the body of each.

INTELLITAG™ with RFID "tap to read" technology comes standard with each unit.

Samson's Defender Fuse with Surge Arrestor will include an additional key component:

Once Defender Fuse is triggered, the internal rope structure is exposed as a visual advance warning of the overload. The ultra-high elongation rope will continue to elongate, up to 150% more than its original length, before complete rupture. In this way, the pink elongating material acts as an early warning system, allowing the crew to take immediate action and manage the load effectively.

When the Surge Arrestor option is included it will engage before full initial elongation and establish an additional ≥ 75% MBLsd connection, providing an additional critical layer of support.

Both products, Defender Fuse and Defender Fuse with Surge Arrestor, are available in two configurations, standard and high recoil control (HRC) ensuring comprehensive mooring safety for various deployments.
