Case Studies

LOPSCO Brush Platers were onsite to repair corroded motion compensator hydraulic rods. Our process saved the customer's downtime, money and the logistic nightmare of removal and reassembly of all 12 affected damaged tensional rods. The team worked a total of 42 days to complete the entire repair.

This ship was scheduled for a deep sea diving operation. While enrouting to destination, the ship encountered a severe storm and the hydraulic shaft of the marine crane was damaged when the chain securing the hydraulic shaft broke and hit against it. The crane was a primary essential equipment for diving operation and replacement of this heavy crane spare-part takes several [...]

All 7 Main Bearing pockets were oversized by 0.25mm. Pockets 2-6 were resized first followed by 1 and 7 to allow for alignment. Copper build up on the Bearing Saddle. The copper plating line-boring back to original dimension and nickel plated for final finish. Repair plating completed and getting ready for re-assembly and return back to customer.

All 8 Bearing Housings were misaligned due to a grouting problem causing severe scoring on the bores. Resized Housings were build-up an average of 0.6mm on radius. Copper is evenly deposited on the Bearing Saddle.

Fretting on Main Bearing Cap caused by bearing vibration. Surrounding edge of Cap was still within tolerance. The bearing cap was hand finished using the surrounding area as the reference. No post machining was required for finish.

Cylinder Heads are exposed to extreme corrosive environment. Cylinder head repair by machining and welding is not the solution as corrosion occurs again in months. Sterling nickel brush plating on Cylinder Head for corrosion protection.  Cylinder Head after repair by LOPSCO Brush plating Process.
