Job Scope for Offshore CCE in the Gulf of Mexico
- A visual inspection of the BOP Gantry Crane was carried and found it to be well maintained. There were no issues identified structurally that would render the safe use of the crane. We also crossed reference our inspection with the previous annual inspection and confirmed that any issues had been rectified.
- The maintenance platform was in poor condition but after a discussion with the sub-sea tech, our team were made aware that cuts had to be made into the handrails to allow the top rack to be traversed fully across. This enables them to carry out maintenance on the top rack traverse gears and grease the hook blocks even poor weather. Safety procedures were in put in place so that a full body harness must be worn while working on top of the gantry.
- A visual inspection of mounted trolley equipment found it to be in a serviceable condition. The following components were also found to be in serviceable conditions:
Main winches (2x hydraulic cylinders)
Aux winches
Cross travel unit
Hydraulic motors
Gearboxes
Traverse gears
Hook blocks
Wire ropes and sheaves
Hard piping
Hydraulic hoses
The newly installed control blocks and cross travel rails - Inspected the HPU and found it to be in a serviceable condition.
- A function test to the BOP Gantry Crane was conducted when the crane was operating. The Alatas team listened out for odd noises and checking for a quick rise in temperature on the motor casing while it was operating. These two things are an early indication of a potential fault but this was no issues were found.
