Inspection & Dimensional Reporting
The crankshaft and related parts go through visual, dimensional, hardness and crack checks on board; findings are delivered in a written condition report.
The checks are carried out without removing the crankshaft. The report is used to decide whether grinding or polishing is needed.

Process Steps
When It Is Needed
- After a bearing seizure, a bearing temperature alarm or rising bearing metal in oil analysis, to establish the extent of the damage
- Before deciding on grinding or polishing
- For a condition assessment ahead of drydock planning or a second-hand vessel purchase
Scope and Limits
- It does not replace a class survey and includes no repair.
- Hidden surfaces of parts that are not opened cannot be checked.
- The final decision rests with the owner and the engine maker.
Frequently Asked Questions
What if the inspection shows that grinding is necessary?
The inspection readings feed the grinding plan; the undersize required is worked out from the same measurements.
Can the report be used for class?
The report provides the measurement data; acceptance is the class surveyor’s decision.
