Cathodic Anode Replacement Completed on Shelf Fortress Jack-Up

June 2025, our multi-skilled welding, rigging and NDT rope access team successfully delivered works on the Fortress, a 400-foot jack-up drilling unit operated by Shelf Drilling.

The scope, carried out at the Service Base in Invergordon, involved the removal and installation of cathodic anodes across all three legs of the Shelf Fortress, with a total of 30 anodes replaced. The project was delivered concurrently alongside multiple other scopes, requiring meticulous coordination and detailed planning throughout.

Executed efficiently and safely, the works were completed ahead of schedule and below budget.
