Last week, the giant Heerema Marine Contractors (HMC) Thialf crane vessel installed the Johan Sverdrup’s 26,000-tonne riser platform, named Ægir.
The jacket which stretches140m from the seabed, covers an area measuring 94 times 64m, says Statoil. It is attached to the seabed by 24 poles weighing more than 9000-tonne in total.
“This is a special milestone for us, because it is the first visible sign of the Johan Sverdrup field. I am happy that the installation has been carried out safely and fully in line with the plan. We are now looking forward to the next steps of this industrial adventure and the long line of major operations awaiting us. We have already done a lot of work on and below the seabed, and in the time ahead we will gradually become more visible above the sea surface as well,” says Kjetel Digre, project director for Johan Sverdrup.
The topside is scheduled for installation next year, and production from the field is to start at the end of 2019.
Statoil says that Sverdrup’s plateau production is estimated at 40% of NCS oil production.
Johan Sverdrup’s expected field life is about 50 years, with a 70% world-class recovery rate. Recoverable resources are estimated to be between 2 and 3 billion boe.
Kvaerner completed the jacket in late-June. The company, along with KBR, has been awarded the contract for three jackets and the utility and living quarters (ULQ) topside for the Johan Sverdrup development.
Work on the remaining two jackets are progressing at Kvaerner’s yard at Verdal, the company said last month, and at Kvaerner’s yard at Stord, the Johan Sverdrup ULQ topside is on schedule.
