Engine Room Overhead Crane: Maintenance and Operational Procedure

To the Chief Engineer, I propose the following procedure to ensure the engine room overhead crane is maintained and operated correctly, focusing on safety, compliance, and longevity.

Proposed Procedure for Crane Maintenance and Operation

1. Daily Pre-Use Checks:

• The duty engineer must perform a visual inspection before each use. This involves checking the wire rope condition (for kinks, corrosion, or broken strands), the hook integrity (for deformation or wear), the functionality of the brakes, and the correct operation of the limit switches. Any defects or abnormalities must be logged and reported to the Chief Engineer immediately, rendering the crane out of service until repaired.

2. Planned Maintenance System (PMS) Integration:

The crane must be fully integrated into the vessel’s Planned Maintenance System (PMS). Scheduled tasks should include:

• Regular lubrication of moving parts (bearings, sheaves).
• Electrical inspections of the motor, wiring, and control panel.
• Periodic testing of the load brake and hoist mechanism.
• Wire rope replacement based on manufacturer's specified running hours or condition.

3. Operational Training and Authorization:

Strict control over operation is essential. Only authorized personnel who have successfully completed formal operational training should use the crane. Training must cover:

• Proper use of the control system and pendant.
• Understanding and adherence to the crane's Safe Working Load (SWL).
• Safe rigging and signalling procedures.
• Emergency stop procedures.

4. Load Testing and Certification:

The crane's integrity must be periodically verified. A mandatory load test must be performed at intervals not exceeding 5 years, or after any major repair or modification, in accordance with flag state regulations.

Required Tests and Certificates

The following certifications are required to demonstrate the crane's fitness for service and compliance with international maritime standards:

Issuing Authority

The required certificates must be issued by a competent authority recognized by the vessel's Flag State Administration. This is typically:

• A Class-approved service provider.
• A Recognized Organization (RO) (e.g., Lloyd’s Register, DNV, ABS, RINA, NK, Bureau Veritas) authorized to conduct surveys on behalf of the Flag State.

All records and certificates must be properly filed and kept ready for inspection by authorities and auditors.
