Offshore Crane Overload Test

Alatas Americas was contracted to complete an offshore crane overload test for a MacGregor / Hydramaine HMC3568-LKO knuckle boom deck crane. The overload test was performed on the crane’s main hook and was part of a 5 Yearly Inspection at Port Fourchon, Louisiana. 

ABS states that all ABS classed cranes are to undergo load testing every 5 years. For cranes with a larger capacity than 50 metric tons, that means an excess of 10% of the maximum SWL.

All global Alatas service stations, including Alatas Americas, have water bags and water weight equipment to carry out load tests for offshore and marine vessels. If you require testing on any of your operational equipment, please Contact Us with your enquiry.
