An Alatas Field Service team took on this Clarke Chapman ship unloader repairs project for a port in the UK. The client’s Clarke Chapman ship unloader (built in 1972), required structural work to the hanger stays.

Hanger stays support the horizontal boom structure during loading operations but had was no longer working to the standard required. 

Through our Engineering Services, Alatas provided an alternative solution to replacing the hanger stays, saving time and costs.

  3. Procurement manufacturing of the material including pins and bushes 
  4. Rope access used due to the flexible nature and to save time with scaffolding 
  5. Line boring and welding which was verified by the engineering team to restore the bores
