Our colleagues working at our reconditioning centre in Suzhou, China, have completed what most likely will be their single largest order of the year 2022.

The work came from an european-owned, 6600 TEU boxship docked in a shipyard in Zhoushan, China. Many components of the 19-year-old, 12 cylinder, 96 cm bore main engine were in need of reconditioning and/or overhauling. Of course our colleagues in Suzhou were more than happy to comply.

The components arrived at our workshop on 30 July 2022 and were returned to the vessel in two batches, on 28 August 2022 and 01 September 2022 respectively. Thus, the work took just took 32 days, from start to finish.

During this time, we reconditioned the following components:

  • 15 pistons: Full reconditioning including coating of the piston ring grooves with the QS50K material
  • 13 piston rods: Reconditioning of the running surface, skimming of the landing surfaces
  • 9 piston skirts: Renewal of the rubbing bandages and skimming of the landing surfaces
  • 12 stuffing boxes:  Overhaul and modification of the housings (upgrade)

The work included dismantling, reassembling and pressure testing where required

This case neatly demonstrates that our reconditioning centres have sufficiently many skilled workers and machining capacity at their disposal to handle even the largest reconditioning orders with ease.
