Harbor hook

type Cquick-releasedouble

Overview
Straatman designs and manufactures quick release mooring hooks for ports, terminals and offshore facilities worldwide. These systems enable safe, controlled release under load and support efficient mooring operations in demanding maritime environments. Quick release mooring hooks can be configured with manual, electric or electro-hydraulic release, mooring load monitoring, and remote control functionality.

Configurations and Release Mechanisms

• Manual release
• Electric release
• Electro-hydraulic release
• Local or remote release from a control panel
• Single, double, triple or quadruple hook units

Product features (example options)

• Integrated vertical capstan — allows hauling in of the mooring line in a safe and efficient way.
• Remote release — hooks can be equipped with an electric or electro-hydraulic release mechanism.
• Mooring load monitoring system — inhook load cell calibration facility; locally and remote controlled by MoorControl software.
• Self supporting — limited movements to prevent contact with the structure; hook parts made of forged steel and counterbalanced.
• Rope keepers — prevent the mooring rope from slipping off the hook in specific situations.
• Explosion-proof version components — for hazardous zones, in conformance with ATEX, IECEx and Class 1 Division 2.
• Manual release lever — can be released manually with an effort of approximately +/- 20 kg at full load.
• Base plate — high quality steel; custom-made base plates to fit existing bolt patterns are available.

Key features

• Mooring load monitoring with integrated load cells to measure mooring line loads; operators view load data locally or remotely.
• Remote control operation enabling release from a safe location to reduce personnel exposure.
• Additional options: rope keepers, integrated vertical capstans, custom foundations, explosion-proof components for hazardous areas.
• Full in-house design, manufacture and testing to control quality, tolerances and performance.

What you receive

• A fully assembled and tested hook system.
• Control panels and electrical components (as applicable).
• User manuals and technical documentation.
• Test certificates and quality records.

Safety, testing and compliance

• All hooks are tested on calibrated in-house testing machines to verify performance under load; standard test certificates are supplied with each delivery.
• Material traceability is maintained from purchase to final production; materials are uniquely identified and supplied with required material certificates.
• Hazardous area solutions: certified electrical and control components available to meet project-specific requirements and standards (e.g. ATEX, IECEx).
• Design and testing aligned with OCIMF Mooring Equipment Guidelines (MEG4) where applicable; final compliance depends on complete mooring arrangement and project requirements.
