HMC hoisted the structures up offshore using its semisubmersable crane vessels (SSCV) Thialf and Hermod, and placed them on large North Sea barges. The barges were towed into AF Decom's decommissioning yard in Vats Rogaland.
Engineering, Preparation, Removal & Disposal (EPRD)
Using multi-wheel trailers, the structures were driven ashore for further dismantling using excavation machines with specially mounted tools.
Detailed engineering phase of 9 months with a great emphasis on safe execution
At Vats in Rogaland, AF has built Europe's most modern decommissioning yard for scrapped marine structures. Here, all the structures from Ekofisk category 1 were received for further processing, recycling and delivery to approved recipients.
Extremely good HSE results were obtained, including no serious incidents or accidents resulting in time off from work, plus there was a recycling degree of 99 percent by weight.
