Cabin Alert: unnoticed damage or deficiency - Regular inspections matter

We address certain key topics that have been brought to our attention by our valued clients during their assessment of inspection reports.


Areas of risk identified

This year, Maersk faced two significant events involving crane cabin conditions which were missed during regular crane inspections. These cases highlight the need for better attention and careful evaluation of the crane cabins.

In one instance, a vessel's crane inspection indicated no structural concerns. However, subsequent reports and photographs from stevedores revealed cabin issues that had gone unnoticed during the survey. Reportedly, the damage didn't compromise the crane's operations, however it highlighted an essential omission during the evaluation process.

Near Accident Wake-Up

Another situation came very close to a serious accident. Despite the inspection did not find any issues, pictures taken afterward by the stevedores clearly showed the cabin’s side window frame and nearby floor was excessively corroded and holed.

These cases remind us to not underestimate checking the condition of crane cabins. Maersk now asks for extra scrutiny on ships older than 15 years.

Seaspan inspection program

For Seaspan inspections we would like to highlight questions 2.13 and 3.9 which in some cases have been overlooked. We would like to emphasize that we need clear photo evidence regarding these items.





Are cable bulkhead penetrations and cable supports in apparent good order? 


The inspector should randomly verify if cable bulkhead penetrations and cable supports are not displaying excessive corrosion or if sealing material of the cable penetrations is missing. 


Is the control panel for the watertight doors operational and are watertight doors in apparent good condition? 


This question requires randomly verify the condition of watertight doors and the remote opening/closing mechanism. Water tightness depends on the condition of the sealing rubbers, the compression bar (knife edge), dog spindles, and wedges.
