Pipe cutting – Snorre A

Project: Removing old water injection pipes.
Installation: Snorre A, Norwegian Continental Shelf.
Scope: Dismantling water injection pipes in manageable chunks.

Challenges:

  • Thick-walled pipes (25 mm walls).
  • Work carried out in classified area where hot work is not permitted without shutting down production.
  • Erecting scaffolding is complex and time-consuming on the site in question. 
  • Complex rigging (long pipes and numerous obstacles).

Solution:

  • Job completed using RAT (rope access techniques).
  • Method/equipment: Pneumatic pipe cutting machines (Clamshell).
  • The operators are highly skilled multidisciplinary mechanics with expertise in fields such as RAT, rigging and cold cutting.

Benefits:

  • Cold work (cold cutting).
  • Small machines mean they are safe and effective when operated at height.
  • The operators are able to complete all the required tasks.
  • Time-efficient cutting method.
  • Good HSE factors and ergonomics.
