CRANKSHAFT FAILURE
& DAMAGE ASSESSMENTS

When a crankshaft is damaged, the most expensive mistakes are made before the damage is understood. We establish what happened, how severe it is, and whether it can be responsibly repaired — before critical work begins.

Where a crankshaft failure is won or lost — understood before it is touched.

//What the assessment covers

Evidence first, then a decision you can defend.

Emergency response

Rapid technical support when a crankshaft or bearing has failed and the engine is down.

Initial damage assessment

Establish what has happened and stabilize decision-making before anything irreversible is done.

Bearing-failure review

Examine bearing condition and wear patterns for what they reveal about the underlying cause.

Crankpin & journal inspection

Surface-condition documentation, MT and PT NDT, and close examination of journals and crankpins.

Dimensional survey

Measured geometry — ovality, taper, alignment, and deflection — recorded against OEM limits.

Repairability evaluation

A technically grounded judgment on whether, and how, the component can be responsibly repaired.

Technical recommendations

Clear options with advantages, limitations, and risks — documented for every stakeholder.

//NDT & documentation

Inspection you can stand behind.

Inspection is performed by personnel qualified and certified in accordance with our employer ASNT SNT-TC-1A written practice for Magnetic Particle (MT) and Liquid Penetrant (PT) testing. We are candid about what each method can and cannot detect, and we combine NDT with dimensional measurement so findings are complete.

Every assessment produces documentation prepared to support technical review and discussions with owners, OEMs, class societies, insurers, and repair stakeholders. Where we may also perform the repair, our findings and measurements are fully documented so others can review them.
