Pre-operational inspection of shipboard cranes

The planning of a cargo operation depends on equipment and information compatible with the intended work. TWS Maritime Service carries out pre-operational inspections of shipboard cranes to document their apparent condition and review the records presented. The service helps shipowners, charterers and operators identify matters requiring clarification before work begins.

When to engage

The service is recommended before operations that will use the vessel's cranes, especially when the client requires an independent record of the equipment made available. Early appointment allows arrangements for access, presentation of documents and any functional checks, without assuming that a visual visit covers all equipment safety requirements.

Scope of inspection

Depending on the type of crane, safe access and the instructions received, the survey may include:

• Identification of the equipment and stated working capacities.
• Review of the certificates and records of inspections, tests and maintenance presented.
• Observation of accessible wire ropes, hooks, blocks, sheaves and structural elements.
• Recording of apparent signs of wear, corrosion, deformation, damage or other conditions warranting assessment.
• Attendance at functional checks conducted by the vessel's authorized crew, where previously agreed and safe.

What the client receives

The report identifies the cranes examined, the documents considered and the checks actually performed. Photographs and descriptions of findings allow outstanding matters to be located; access restrictions and items requiring specialist examination are presented separately. This record facilitates discussion of actions with the vessel and other responsible parties.

Limitations and supplementary checks

The pre-operational survey is not equivalent to a load test, periodic thorough examination, class certification or formal authorization for use. SOLAS II-1/3-13, in force since 1 January 2026, establishes requirements for the equipment covered; its application must take account of the equipment, the vessel and flag State requirements. Specialist tests require separate engagement and appropriate resources.

Request this service

Provide the vessel's name and IMO number, port, operational window, number and characteristics of the cranes, intended cargo and available certificates. Clearly state the tests requested so that we can verify their feasibility and the means required.

Frequently asked questions

Does the inspection demonstrate lifting capacity by testing?

Not by itself. Checking the stated capacity and documentation differs from carrying out a load test. The report identifies exactly what was observed or attended.
