Quick Release Hook (QRH)

1. Introduction

Quick Release Hooks (QRH) are specialized mooring devices designed to secure vessels at ports, jetties, or offshore platforms, while allowing instant release of mooring lines when necessary. QRH enhances operational efficiency, ensures safety, and reduces handling time compared to traditional methods.

2. Structure

Hook body: Withstands mooring line tension, usually made of high-strength steel.
Base foundation: Fixed on the quay or jetty to ensure stability during mooring.
Quick release mechanism: Can be activated manually, electrically, or hydraulically for instant release.
Drive unit (optional): Assists in smooth hook release operation.
Load monitoring sensor (optional): Measures mooring line tension for safe mooring management.

3. Working Principle

When a vessel berths, mooring lines are secured onto the Quick Release Hook and locked.
The QRH system stabilizes the vessel, minimizing movement caused by waves or currents.
In case of emergency, the release mechanism can be triggered manually, electrically, or hydraulically to instantly free the lines.

4. Applications

Ports and harbors: Improves cargo handling efficiency and reduces mooring time.
Oil & gas platforms: Secures supply vessels, ensuring safety during emergency release.
Emergency situations: Allows vessels to depart quickly during storms, fires, or collisions.

5. Benefits

Enhances safety during mooring and release operations.
Saves operational time and increases port productivity.
Reduces manual labor with automated release options.
Protects mooring lines, hooks, and vessels from excessive loads.
Supports safe monitoring with load sensor integration.

6. Types of Quick Release Hooks

Single hook: Suitable for small vessels or simple mooring systems.
Double hook: Ideal for large ports requiring multiple mooring lines.
Triple & quadruple hook units: Designed for industrial terminals, oil tankers, and large cargo ships.
QRH with load monitoring: Integrated with advanced tension measurement technology.

7. Conclusion

Quick Release Hooks (QRH) are a modern solution to optimize mooring operations and enhance maritime safety. With rapid release capabilities, QRH systems are widely applied in ports, offshore platforms, and emergency conditions, improving operational efficiency and vessel protection.

Mooring Bollard Accessories

Installation

Easy installation process.
Anchor bolts (connecting bollards to quay surface) can be embedded during concrete casting or installed later using chemical anchors or Sika compounds.
Bolt positioning is supported by templates, ensuring accuracy and compliance with port engineering standards.
Mooring bollards are installed using cranes, support vessels, and basic construction equipment.

Quick Release Hook Quality

Quality certified by international standards: PIANC, BV, or independent third-party organizations such as TT3 (Quartest 3) Vietnam, SGS, etc.
Durability up to 10–15 years (depending on port operation conditions), ensuring long-term performance.
Warranty from 1–2 years (based on port design requirements).
