Overview
Straatman Quick Release Mooring Hooks are engineered and manufactured in the Netherlands for ports, terminals, LNG jetties, offshore facilities and mooring buoys worldwide. They allow operators to release mooring lines safely and in a controlled way, even under load. Systems are available with manual, electric or electro-hydraulic release, optional load monitoring, remote release and integration with berth and environmental monitoring systems.

Applications

• Oil, gas and chemical terminals
• Bulk terminals (coal, ore, grain)
• Container and general cargo terminals
• LNG terminals
• Offshore jetties, FPSO and FSRU vessels
• Mooring buoys and single-point moorings

Key features and configurable options

• Single, double, triple or quadruple hook assemblies
• Manual, electric, hydraulic or electro-hydraulic release mechanisms
• Local and remote release (control panel / remote operation)
• Integrated vertical capstan for hauling in mooring lines
• Optional Mooring Load Monitoring System (MLMS) with in-hook load cells
• Integration with MoorControl software and berth/environmental monitoring systems
• Self-supporting hooks with limited movement to prevent contact with structure
• Forged steel hook parts and counterbalanced design
• Rope keepers to prevent rope slipping where required
• Explosion-proof / hazardous-area components available (ATEX / IECEx / Class 1 Division 2)
• Manual release lever operable at full load with an effort of approximately +/- 20 kg
• Custom base plates and foundations to fit existing bolt patterns
• Surface preparation and coatings to ISO 12944 (C5M) standard; standard finish RAL 9005 (black); alternative coating suppliers available

Quick release with load capability
Hooks are designed to release a mooring line while under tension up to the unit's rated capacity. Safe Working Load (SWL) ratings are supplied per hook (examples: 100, 150, 200 metric tonnes); multi-hook assemblies combine individual hook capacities to reach the required total capacity depending on vessel and berth analysis.

Mooring Load Monitoring System (MLMS)
The MLMS uses a dedicated load cell fitted in each hook to measure the force on the mooring line. Load data is displayed to the operator (local and remote) to provide insight into mooring situations during operations and to trigger warnings when loads exceed thresholds.

Safety, testing and compliance
Straatman tests all hooks on calibrated in-house testing machines and supplies standard test certificates with each delivery. Testing can be witnessed by classification authorities where required. Hooks can be supplied with certified electrical and control components for hazardous areas in accordance with project-specific requirements. Designs are made in line with industry guidance including OCIMF Mooring Equipment Guidelines (MEG4) where applicable.

What you receive

• Fully assembled and tested hook system
