Our GMH-type quick release mooring hooks are routinely deployed on mooring buoys. By default, they feature a rope keeper to prevent inadvertent detachment of mooring lines, notably during pronounced wave movements. These hooks are commonly provided as individual units, crafted for seamless integration into the buoy's infrastructure. Nonetheless, they can also be obtained in multi-hook configurations. 

Quick release buoy hooks

The GMH standard mooring hook is engineered for straightforward operation, even at its peak Safe Working Load (SWL). It encompasses a two-step release mechanism to deter unintentional disconnections. All our quick-release mooring hooks can be readjusted effortlessly through a rotational action. When released, rubber blocks are incorporated to mitigate the energy impact. 

Our quick-release buoy hooks cater to a diverse range of capacities, from 40 to 200 tonnes (SWL per hook).

Wide range of options

The operation of a mooring hook on a buoy carries inherent risks, particularly during adverse weather or when the quick release is engaged under stress. With the safety of mooring operators as a primary concern, our products are devised, integrating features such as the two-step release mechanism and energy-absorbing rubber blocks. 

All our mooring buoy hooks can be outfitted with: 

  • Options for both automatic and remote-controlled release; 
  • A unified hydraulic power pack facilitating automatic release; 
  • An accurately calibrated load pin; 
  • A solar energy system; 
  • Components that are explosion-resistant, adhering to ATEX/IECex regulations.

Telemetry system

We've innovated a telemetry system that empowers port operators to supervise their mooring buoys from a distance, thus elevating safety standards. 

The Straatman Telemetry system offers: 

  • An inbuilt load-monitoring application; 
  • Automated release software integration; 
  • An expansive logging capability that chronicles all alarms, data entries, and vessel-related activities; 
  • A mobile apparatus showcasing the entirety of the integrated software, safe for use even in hazard-prone zones (ATEX certified). 

Adopting the Straatman Telemetry System for mooring buoys ensures: 

  • Enhanced safety protocols for operators, equipment, and the surrounding environment; 
  • A heightened ability to act promptly in the face of hazardous scenarios; 
  • Comprehensive mooring data insights that drive procedural enhancements.
