Offshore Decommissioning Services

With over 35 years’ experience, LOC has gained a long track record in offshore oil and gas decommissioning, dating back to Brent Spar and Maureen Alpha removal. We have built a reputation as a leading international consultancy company to the world’s offshore decommissioning industry and an active member of the SUT’s salvage and decommissioning committee.

Experts at Offshore Decommissioning

LOC has the market-leading technical expertise to support you in every decommissioning project you have – any size, any type, and anywhere in the world. Our first high profile decommissioning project was Brent Spar where we provided warranty and consultancy services to Shell for the disconnection, wet tow, deconstruction and eventual re-use in jetty construction of the spar structure.

We have worked on a wide range of different types of decommissioning projects and discrete operation types in the majority of the world’s major offshore oil and gas producing regions including:

  • Spar tow and deconstruction
  • Steel GBS platform removals and deconstruction
  • Topsides removals (piece small, modular lift, single lift and float-off)
  • Fixed jacket, piles and template removals (piece small, single lift and re-float)
  • FPSO disconnection and tow (Including yolk, external riser turret, internal turret and spread moored vessels)
  • FPSO mooring systems and riser removals
  • Articulated loading columns, CALM buoys and other loading systems
  • Flexible and umbilical recoveries (including associated riser bases and lay-over arches etc)
  • Manifolds, X-mas trees, well-head and other subsea structure removals
  • Pipeline abandonment including cleaning, flushing and rock-dumping
  • Semi-sub & drill rig tow and disposal

Leading the Industry

Our collaborative approach to each project allows us to work with all the relevant parties to consider, review and approve innovative removal methods and systems. Such as, Buoyancy Tank Units (BTU) used on Frigg jacket removal and weld-less sea-fastening.

LOC was involved in the first use of Pioneering Spirit on the decommissioning of the Yme platform. This project typifies our approach from early marine advisory through to final MWS approval.

Whatever your decommissioning project entails we have the skills and experience to assist.
