Catalog excerpts

Trelleborg Marine Systems | Performance People Quick Release Hook Compact Series Description The Quick Release Hook units are available with single or multiple hooks in capacities up to 50T. Each hook cantilevers from the mounting base and the design ensures the hook cannot impact the deck under any loading configuration. The Quick Release Hook is designed to be released by an operator when a mooring line is attached, even under full load. The capability to include remote release enables controlled releases of mooring lines from a central location, efficiently and safely. This keeps mooring crews clear of lines during departure and provides a method of quickly releasing the vessel in the case of an emergency, or where access to moorings is restricted. When fitted with Trelleborg’s load monitoring system, mooring line tension can be monitored to provide real time information and alarm conditions fundamental to safe mooring. In addition to increased safety and asset protection, the ability to provide feedback to the ships mooring crew, allows mooring lines to be tensioned with the ships winches to provide a balanced mooring pattern which ensures the vessels stability at berth. This maximizes the ability to efficiently load / unload the vessel. Note: remote release and load monitoring details are covered in separate datasheets.

Key Features & Benefits Trelleborg QRH’s are field proven since 1972 and installed in over 500 mooring facilities worldwide. The Small Scale QRH combines the knowledge of Trelleborg’s experienced engineering team with the benefits of FEA analysis software, to develop an optimized solution for small scale mooring applications. A hook side plate design which: Accommodates load monitoring at zero degree line angles, without having to hang the hook downward. Reduces the overturning moment on the hook base and subsequently the stresses on the hook base and the hook base foundations. Some of the...
