LANKHORST’S ANTI-SNAPBACK SOLUTION THE DEVELOPMENT, TESTING AND SAFE USE RECOMMENDATIONS
€0.00
Summary
In recent years, the maritime industry has placed increasing emphasis on safety during mooring, tugging, and towing operations. Safer ropes are no longer considered an added benefit but a critical requirement, as rope failure in these contexts can lead to severe accidents, as evidenced by past incidents.
In response to this need, rope manufacturers have developed reduced-recoil-risk ropes that provide visual or physical warnings prior to failure and are designed to break in a controlled, sequential manner. However, not all anti-snapback solutions are created equal, as their effectiveness largely depends on the rope’s construction and materials. Lankhorst has addressed these challenges with a reduced-recoil-risk design that incorporates stronger strands within the rope’s construction. These strands temporarily maintain the rope’s integrity after initial failure, reducing the original stored energy to a much lower level, thus reducing the risk of sudden recoil and potential injury.
This paper explores Lankhorst’s development of anti-snapback technologies, examining key aspects such as test specimens, standardized testing methods, performance parameters, and recommendations. It also discusses the limitations encountered during development and the strategies used to overcome them.
