Company Profile

OEG Offshore is a global supplier of Cargo Carrying Units and A60 Specialist Engineering Cabins.

OEG Offshore offers its wide range of services on a nationwide basis from depots located in Perth, Karratha, Broome, Darwin, Melbourne and Gippsland.  Those services include third party inspections, heli-deck audits (CAP 437), fluid handling, specialist design and fabrication and rigging solutions.

Objectives

CAPS was invited to inspect two Gardner Denver compressors for a possible overhaul. Upon completion of the site visit, CAPS provided a descriptive outline of what work was required to bring these compressors back into good reliable condition.

Solution

The two Gardner Denver units were delivered to CAPS’ Melbourne Branch workshop. The first job performed on both units was the removal of the heads and cylinders for an inspection. The sump covers were also removed so we could inspect the con-rod bearings end cap, plus the condition of the con-rods.

All valves from both units were removed and sent away for an overhaul, and all gaskets were sent away for manufacturing. Piston rings and oil scrappers were sent to a supplier so that new rings and scrappers could be made. The cooler from the water cooled unit was removed and sent away for testing—this test failed. 

CAPS recommended the unit be transformed into an air-cooled unit, in which OEG accepted. Therefore, the process of building new discharge pipe and blanking the water ports was completed.

During the stage where CAPS was waiting for the parts to return from the suppliers, the units were stripped completely and cleaned, ready for reassembly and sandblasting process. When all parts were returned from the external suppliers, assembly of the units was scheduled and completed. All clearances were checked on the piston rings to cylinders and bearings to the con-rods.

The units were then sent to be sandblasted and painted to the exact specification supplied by OEG for this project. The units were then returned to CAPS’ workshop, where we were able to complete the re-pluming of the control lines in the new copper tube. New control line fittings, new safety valves, control valves, pressure gauges and belt guards were also fitted.
