Project Description
Johan Sverdrup is one of the five largest oilfields on the Norwegian continental shelf. The project has estimated resources of between 2.1-billion and 3.1-billion barrels of oil equivalents. The project will be developed in two phases.
Phase 1 includes the development of utility and living quarters, and processing, drilling and riser platforms; three subsea installations for water injection; power from shore; and an export pipeline for oil (Mongstad) and gas (Kårstø).
Phase 2 includes the development of another processing platform for the field centre and the Avaldsnes, Kvitsøy and Geitungen satellite areas, in addition to power from shore to the Utsira High by 2022.
An area-wide solution for power from shore to the Utsira High area is an integrated part of the Phase 2 development, where another power converter will be installed on the new processing platform.
Potential Job Creation
Not stated.
Value
Phase 1 is expected to start production in late 2019.
Phase 2 is expected to production in 2022.
Duration
Phase 1 will cost an estimated NKr88-billion and Phase 2 NKr45-billion.
Latest Developments
The cable-laying vessel NKT Victoria has started laying the cable that will supply Johan Sverdrup with power from shore. This helps make the North Sea giant one of the oil- and gasfields with the lowest carbon dioxide (CO2) emissions in the world.
Estimated at just 0.5 kg of CO2 a barrel, the emissions from Johan Sverdrup are about 20 times lower than the average on the Norwegian continental shelf, and 30 times lower than the international average.
The starting point is the Johan Sverdrup converter station at Haugsneset near Kårstø; the vessel will have laid nearly 200 km of power cables out to the field in the North Sea by the end of May.
Bundled with the power cables, a fibre-optic cable will, once installed, ensure good communication and allow for monitoring and, when required, remote control parts of the Johan Sverdrup field’s operations from shore.
Several additional measures have been implemented to further reduce emissions during the Johan Sverdrup development. The NKT Victoria has been designed to be supplied with power from shore while in harbour.
The mobile accommodation vessel Haven, which will be in use at the field from June onwards, has also been modified to use power from shore while in service at the Johan Sverdrup field.
Based on current plans, the field will be powered from shore from the second half of this year so that all the field’s power needs during the remaining hook-up and finalisation phase will be met with electricity supplied from shore.
After the start-up of the second phase of the development in 2022, the Johan Sverdrup field will also enable power from shore to reach the remaining fields – on the Utsira High – Edvard Grieg, Gina Krog and Ivar Aasen.
Key Contracts and Suppliers
Aibel (EPC of the topside for the second Johan Sverdrup processing platform) and Aker Solutions-Kværner JV (EPC of a utility module for the riser platform, field-centre modifications, and installation and hook-up activities related to the Phase 2 development).
