Quick Release Hooks (QRH)

Your Modern Mooring Systems Partner

Quick Release Hooks (QRH) by Glen Engineering

Quick Release Hooks (QRH) are a vital necessity for safe and efficient jetty mooring operations, particularly at terminals handling and transporting Liquified Natural Gas (LNG), Liquified Petroleum Gas (LPG), chemicals, oil and coal.

Quick Release Hooks (QRH) are a necessity for today’s mooring systems. Glen’s QRHs enable mooring lines to be secured quickly and safely. OUR QRH’s are easily released even when loaded to their safe max working limit. 

Failing mooring lines, failing hooks or structural failure are all too common hazards which can create considerable damage to ships and berths, and disrupt operations – so too great and too expensive a risk to be ignored.

FAQ

The correct SWL selection should follow the dynamic mooring analysis done by the consulting company to obtain the value.
Please also note that according to the OCIMF Meg3 guidelines, it is recommended that the SWL of each hook is larger than the MBL of the mooring.
For example, for LNG carriers using 140T MBL ropes, SWL150T quick release hooks are usually designated

A. The capacity of a capstan is usually specified by its line pull. This is sized according to the weight of mooring line
expected to be hauled in from the vessel to the mooring point. This will be greater for mooring dolphins than berthing dolphins; however, capstans are specified by maximum line pull to provide standardised equipment across the berth.

A. Each hook can accommodate two mooring lines up o a diameter noted in the datasheet. However, most
modern berths utilise load monitoring, and for this to be effective as a management data tool, each hook should
be dedicated to a single mooring line.

A.single or inherited detection system, such as: stress monitoring, environmental monitoring, laser berthing, including remote fault diagnosis and monitoring, can prevent faults, easy maintenance, and speed up turnover. It is the standard configuration of most modern terminals .

A.According to OCIMF/SIGTTO guidelines for jetty equipment, Hooks require regular greasing and basic inspection,
Instrumentation requires routine inspection inspection every year.
load cells requires calibrated annually.
