Overview
ISO 21132:2019 establishes comprehensive operation and maintenance requirements for marine cranes used in harbour or sheltered water conditions. This international standard specifically covers various types of marine cranes, including electro-hydraulic cylinder and wire rope luffing cranes, as well as electric wire rope luffing cranes. It applies to deck cranes mounted on ships, floating cranes on barges or pontoons, grab cranes, and engine room or stores cranes used for handling equipment, cargo, containers, and stores in protected waters.
The standard aims to ensure safe, reliable, and efficient operation of marine cranes by defining essential documentation, pre-operation inspections, operational protocols, maintenance plans, and troubleshooting procedures.
Key Topics
-
Scope & Applicability
ISO 21132:2019 is relevant for marine cranes operating specifically in harbour or sheltered water environments with wave heights not exceeding 0.6 meters. It encompasses multiple crane types mounted on various marine vessels and platforms.
-
Documentation Requirements
Essential documents must be maintained throughout the crane's lifetime, including:
- Manufacturer certificates verifying design, manufacture, and testing
- Instructions for use covering installation, operation, inspection, maintenance, and troubleshooting
- Maintenance and repair records
- Regulatory certificates such as those required by ILO C152
-
Pre-Use Inspection & Operation
Operators are required to perform detailed inspections before use, verifying:
- Structural integrity and condition of all crane components and loose gear
- Correct function of safety, control, and limiting devices
- Visibility and clearance of operation area
- Environmental conditions within operational limits (e.g., wind, waves, temperature)
During operation, continuous monitoring of load conditions, crane movements, and environmental changes is mandated to avoid exceeding operational limits and to maintain safety.
-
Post-Operation Procedures
After use, cranes must be powered down, locked, and securely stowed according to manufacturer instructions. Damages found must be recorded and repaired promptly. Loose gear should also be safely secured.
-
Maintenance & Inspection
A detailed maintenance plan must be provided by the manufacturer, addressing:
- Structural, mechanical, electrical, hydraulic, and safety system components
- Identification of wear-prone parts like wire ropes, brakes, and bearings
- Maintenance intervals and documentation
In case of maintenance or inspection issues beyond standard procedures, the crane manufacturer or authorized personnel must be consulted.
- Troubleshooting
Common operational issues should be managed onboard by qualified personnel as guided by the manufacturer’s instructions. Any unresolved or safety-critical issues require intervention by the manufacturer or certified technicians. Defective cranes must be removed from service immediately.
Applications
-
Port and Harbour Operations
Ensures safe handling of cargo, equipment, containers, and stores on ships and floating platforms under sheltered water conditions where wave action is minimal.
-
Marine Cargo Handling
Enhances reliability and safety for various marine vessels’ crane operations, supporting efficient loading and unloading processes.
-
Shipboard Equipment Management
Facilitates the secure operation and maintenance of engine room cranes and store handling cranes, minimizing operational risks during harbour maneuvers.
-
Safety and Compliance Management
Supports vessel operators and maintenance crews in adhering to regulatory and safety standards for maritime crane operations per international best practices.
