Quick Release Offshore Hooks

  • Stand large tonnage pull
  • Remote or emergency release from the control room panel
  • Customize product for different demands


Floating Production Storage and Offloading (FPSO) units are commonly used in offshore oil and gas production for hydrocarbon processing, oil storage and more recently facilitating the production and transportation of liquified natural gas (LNG). Safety is paramount for the side-by-side mooring of ships, shuttle tankers, and other vessels to an FPSO, especially in the open sea. Managing a safe working load (SWL) ranging between 60 and 600 tons in weight, hooks are usually deployed for tandem or side by side mooring.

Developed specifically to meet the demanding requirements of FSO, FPSO, FLNG moorings, Glen’s high-quality Quick Release Hooks provide resilient and safe mooring for all situations.

Advanced Offshore Hook Design

Glen Quick Release Offshore Hook is designed in accordance with Oil Companies International Marine Forum (OCIMF) recommendations, as described in:

Recommendations for Equipment Employed in the Bow Mooring of Conventional Tankers at Single Point Moorings (4th Edition)
OCIMF Tandem Mooring and Offloading Guidelines for Conventional Tankers at F(P)SO Facilities (1st Edition).
Glen’s Quick Release Hooks have Marine type approval to LR, DNVGL, ABS, BV and RINA, as applicable.

The most common safe working load (SWL) for standard Quick release offshore hooks is 200/250 tons. Glen’s advanced manufacturing facility can design and produce hooks for higher capacities if required.


  • Stand large tonnage pull
  • Remote or emergency release from the control room panel
  • Customize product for different demands
  • Optional load monitoring with calibration services
  • Preventing accidental or inadvertent release


For safer tandem mooring of shuttle tankers to FSO, FPSO, FLNG and Buoys etc.

GLEN provides a wide range of configurations for Quick Release Mooring Hook,

Making it suitable for a the wide majority of mooring applications.


Control system

To achieve the highest possible levels of operational performance safety, Glen’s Quick Release Offshore Hooks can be fitted with several control system types:

  • Manual Control: Operation by Means of a Release Lever
  • Hydraulic Control: Operation via a Locally Situated Control Panel
  • Remote Control: Operation From either a Control Room or the Vessel’s Bridge

Load monitoring

Real-time hook loads data can be relayed via a local panel and/or on a bridge panel, with the option available to show loads data as a trend on a chart recorder. In the event of the hook load exceeding a predetermined limit, audible and visual alarms are generated.

Calibration Services

All Glen Load Cells are calibrated during the load test and – during an Overall System Test – on a specially calibrated test bench. Calibration service is also available. All Glen-issued calibration certificates correspond to widely accepted Marine type approvals, including LR, DNV, RINA, and ABB.

Special Variations

Glen is able to customize systems to accommodate:

  • Break Odd Bolt Constructions
  • Side-by-Side Mooring Units With Different Hook Configurations
  • Chain Stoppers
  • Buoy Hook Systems
