Replacement of 100Te Crane Jib
The hydraulics failed on a 100Te crane in the Gulf of Mexico and the very long crane jib folded over the edge of the semi-sub.
We were asked to replace the jib as fast as possible which we did on shore in Mexico.
The steel tube was AISI 4130 which required post weld heat treatment, the heat treatment was successfully carried out while still maintaining the absolute straightness of the jib.
