Spanish Dragados Offshore has delivered the final jacket for the Equinor-operated Johan Sverdrup Phase 1 project located in the North Sea off Norway.

Dragados said on Monday that the 7,600-tonne steel jacket for the living quarter platform sailed away on July 30 from the North Pier of the company’s yard in Puerto Real, Cádiz, in Spain.

The company’s scope of work under the contract, which was awarded in 2015, included engineering, procurement, and construction, preservation, loadout, transportation grillage, sea-fastening, and sail-away preparations for transport to the final offshore location of the Johan Sverdrup field.

The four-legged lifted jacket has a top-of-jacket geometry of 40 meters x 28 meters and bottom-of-jacket geometry of 45 meters x 45 meters, with a design life of 50 years.

Three Kvaerner jackets delivered

Dragados added that the project was completed before the scheduled date and with no incident or accident during the project duration.

The living quarter platform jacket is the only one of four Johan Sverdrup jackets not built by Norway’s Kvaerner.

Kvaerner has already delivered the three largest and most complex substructures out of four for the first phase of the Johan Sverdrup project.

The first delivery was the riser platform jacket in the summer of 2017 while the second and third were delivered in March 2018 and on July 28, respectively.

 

Topsides – Two installed, two to go

 

The giant Johan Sverdrup oil field in the North Sea offshore Norway will be developed in two phases.

The first phase involves the establishment of a field center consisting of four platforms, including a utility and living quarters platform, a processing platform, a drilling platform and a riser platform. The platforms will be interlinked by gangways.

Equinor installed the first of four topsides on the North Sea development – the riser platform topsides – in late April. In early June, Allseas’ Pioneering Spirit single-lift installation/decommissioning and pipelay vessel installed the 22,000 t drilling platform topsides for the Johan Sverdrup project.

The Pioneering Spirit will return to the field in the spring of 2019 to install the 26,000 t process platform topsides and the 18,000 t living quarters platform topsides.

Johan Sverdrup production start-up is scheduled for end 2019 with production capacity estimated at 440,000 barrels of oil per day.

As for the second phase of the development, the field development plan is expected to be submitted later this month. Read more on that HERE.
