A quick release mooring hook secures and releases a mooring line on a jetty, berth or offshore structure. Unlike conventional bollards, the hook releases the line under load and improves safety during normal and emergency operations.

A quick release mooring hook system provides controlled, safe, and efficient mooring for vessels in ports and terminals.
You mainly see these systems in . Oil and gas terminals, Chemical and liquid bulk terminals, Liquefied natural gas terminals, Dry bulk terminals (coal, ore, grain), Container and general cargo terminals amd Offshore jetties and single-point mooring locations. Typical reasons to use quick release hooks include improved safety, better operational control, faster mooring and unmooring, and the ability to release a vessel quickly in emergencies.

Yes. A quick release mooring hook releases a mooring line while it is still under tension, up to the hook’s rated capacity.
This capability is critical during emergency situations. In such cases, operators cannot gradually reduce line loads and must release the vessel quickly. Unlike manual release from a bollard, a quick release mooring hook enables controlled release from a safe distance and improves safety for quay personnel.

The safe working load (SWL) defines the maximum line load that a quick release mooring hook can safely hold and release.

Straatman supplies each hook with a defined rating, such as 100, 150 or 200 metric tonnes. The required capacity depends on vessel size, environmental conditions, mooring line layout and the results of the berth mooring analysis. When a unit includes multiple hooks, the total capacity equals the combined capacity of the individual hooks.

Quick release mooring hooks support configuration for each terminal or offshore facility. Common options include:
– Single, double, triple or quadruple hook units
– Manual, electric or electro-hydraulic release
– Local or remote release from a control panel
– Integrated capstans for line handling
– Load monitoring and system integration
– Custom foundations, coatings and explosion-safe versions

Yes. Straatman supplies quick release mooring hooks with certified components suitable for hazardous environments.
Where required, electrical and control components can be provided in compliance with applicable standards such as ATEX and IECEx. The final hazardous area classification and certification depend on the project-specific requirements and installation environment.

Straatman designs and tests quick release mooring hooks in line with the OCIMF Mooring Equipment Guidelines, 4th Edition (MEG4). These guidelines describe industry best practices for the safe design, testing and use of mooring equipment at tanker and gas terminals.

Final compliance always depends on the complete mooring arrangement and the project-specific requirements.

Straatman manufactures quick release mooring hooks from high-quality steel components and produces them in the Netherlands.
By controlling the process in-house, we ensure consistent quality, reliable performance and compliance with applicable international guidelines. Material selection and final specifications depend on the project requirements and operating environment

Straatman applies strict surface preparation and coating standards to ensure long-term corrosion protection.
As standard, surface preparation complies with ISO 12944, corrosion category C5M. We use coating systems supplied by Hempel, with RAL 9005 (black) as the standard finish. Alternative RAL colours or coating systems from approved suppliers such as International, Jotun or Sigma can be provided upon request.

In addition to quick release mooring hooks, Straatman supplies a complete range of mooring and berthing solutions, including:
– Berthing Aid Systems (Docking Aid Systems)
– Control panels
– Software solutions
– Environmental Monitoring Systems (EMS)
– Portable devices
– Smart bollards

Straatman integrates these systems to support safe, efficient and well-controlled terminal mooring operations.
