Offshore

Location:

North Sea

SOW:

Refurbish back to OEM specification

Result:

Initially both cylinders were stripped down to their component parts and inspected to generate a detailed workshop appraisal report. Both cylinders required replacement 431 stainless steel cylinder rods and the cylinder tubes required honing to remove light scoring and glazing.

New OEM seal kits were installed to return cylinders to original specification and new replacement cylinder/rod mounting pins were manufactured from 316L stainless steel including new keeper plates.

The cylinders were function tested and pressure tested as per the original specification.

Both cylinders required a marine specific coating as provided by the client.
