Scope of Work
- Both forward and aft liners were machined and polished to remove the seal running grooves
- The seal box and spacer plate spigot were machined by 1 mm to achieve the correct wear downs
- The seals were reassembled with new sealing rings and bolted on with new washers
- Checking of the alignment
- The stern tube refilled, and the seals’ pressures were tested
- The seal cambers were filled, and new anodes fitted
After 36 years of service, some corrosion on the aft seal housing was noted, though the housing was still good enough to reuse. The housing will be re- checked at the next docking
