Benefits of Load Monitoring in Quick Release Hooks

Quick release hooks (QRHs) are essential for advanced maritimeenergy, and lifting mooring systems. These specialized hooks ensure safe and efficient mooring operations by securing lines quickly and, most importantly, releasing rapidly, even under heavy loads. This capability significantly enhances safety and efficiency in demanding environments requiring rapid response.

QRHs are more than simple connectors. Advanced models integrate load measuring pins that monitor the forces acting on mooring lines. This data lets operators respond immediately to dangerous situations like slack or overloaded lines. Integrated alarms can trigger when loads exceed safe working limits, adding another layer of safety.

Types of Quick Release Hooks Using Load Pins

  • Quick Release Mooring Hooks
  • Quick Release Towing Hooks
  • Quick Release Hooks for Offshore Operations
  • Quick Release Hooks for Airlifts
  • Quick Release Hooks for Lifting, Rigging and Hoisting
  • Quick Release Buoy Hooks
  • Quick Release Hooks for Aquaculture

Traditional mooring systems can pose significant risks. Failing lines, hooks, or even structural failures can lead to substantial damage, operational disruptions, and personnel endangerment. QRHs address these challenges by enabling rapid release and minimizing the potential consequences of such incidents.

Defining Requirements for Load Measuring Quick Release Hooks

To design an effective Quick Release Monitoring System using force measurement solutions, consider the following key factors:

  • Maximum Angle of Movement – Determine each hook’s maximum range of vertical and horizontal motion. Excessive movement can impact measurement accuracy and potentially damage components. This information is crucial for selecting suitable load pins and mounting arrangements.
  • Operating Height – The hook’s height influences communication and display options. Consider whether local or remote monitoring and wireless communication are necessary.
  • IP Rating – Define the equipment’s required Ingress Protection (IP) rating. This rating indicates protection against dust and water ingress, ensuring reliable operation in harsh environments. Will you need a subsea, submersible, or splash zone design?
  • Monitoring Frequency – Determine the necessary frequency of load monitoring. Continuous monitoring may be essential for critical applications, while periodic monitoring may suffice for others. This decision impacts data acquisition and processing requirements.
  • Real-time Data Display – Specify whether real-time load information needs to be displayed. If so, consider the type of display (local or remote) and the required data visualization format.
  • Data Logging and Analysis – Define requirements for data storage and analysis. How will the collected data be used for performance monitoring, maintenance planning, or process optimization?
  • System Integration – Explore potential integration with other systems, such as alarm systems, control systems, or data visualization platforms, to enhance overall functionality and efficiency.

By carefully defining these requirements, you can ensure that your quick release monitoring system meets your specific operational needs and provides valuable insights into mooring line forces.

Interface Measurement Load Pins Ideal for Quick Release Hooks

Interface provides standard and custom solutions for load pin integration into quick release hooks. Our load pins and load shackles are commonly used for QRH applications. Engineers select Interface for our durability, quality and accuracy of measurement. We have supplied hundreds of load pins to quick release hook OEMs and end users to facilitate the retrofitting of a mooring load monitoring system or simply replace damaged or older load pins.

We can supply them with amplified outputs, external grease ways, and cable glands and cables that meet individual customers’ specifications. We have also designed and supplied many ATEX and IECEx options for use in hazardous areas.

All our load pins are internally gauged to protect the strain gages and maximize design life. When a force is applied, the resulting deformation is produced. Superior linearity over other designs. High levels of environmental sealing can also be achieved (IP68/69).

Quick Release Hook (QRH) system

Quick Release Hook System

A customer wants to test the strength of the cable line used in the hoist of their vessel. They need to test their advanced Quick Release Hook (QRH) System when their vessels are docked to ensure the mooring lines are secured and the hooks can be easily and safely released. Interface’s WTSLP Stainless Steel Load Pin can be installed into the quick release hook, where forces from the mooring lines can be measured and displayed when paired with the WTS-BS-4 USB Industrial Base Station. The WTS-RM1 Wireless Relay Output Receiver Module alarm can also be triggered for the customer when maximum safety workload capacities are reached or overloaded.
