As part of its decommissioning offering,
The report spotlights the quantity of all materials yielded in decom work. For topsides that broke heavy lift records when they were installed, that's a lot of valuable raw materials recovered.
More sustainable economic activity means reusing as much steel and other materials as possible, as far less energy is used recovering recycled materials than in the production of, say, ingots of steel. Steel recovered offshore has unique qualities and uses.
But the work reducing towering oil platforms into, say, additives for 3D printing can be 'brutal'. The Valhall drilling platform's final journey - carried on the 'back' of the Pioneering Spirit heavy lift vessel - ended in
Explosives sped the demo along and made it safer by bringing heavy steel structures to ground level, making for less work at heights. Hydropower drove the stationary-scissor and water-grit cutting machines, ensuring lower emissions and noise pollution.
Decom and newbuilds
Decommissioning the original Valhall installations concludes a fascinating chapter in the Norwegian oil and gas story. A giant on the Norwegian continental shelf, Valhall has produced over a billion barrels of oil equivalent since the original field came entered production in 1982. Two of its platforms were recycled at
While the Valhall originals will live on as raw materials,
Recycled material and equipment from the old Valhall platforms could yet find its way onto the newbuild topside.
Growth market
About 10,000 platforms now in operation worldwide will one day have to be decommissioned - a giant salvage market. That means a corresponding trove of recovered raw materials are now also within the reach of
Much of that decommissioning stems from both the
