The Luva field, which is a deep-water pioneer in the Norwegian Sea, may be the first to have a Spar platform on the Norwegian continental shelf (NCS). The field is located outside of existing infrastructure and has a water depth of 1,300 metres.

“This development may represent the start of deep-water production in the Norwegian Sea, and it will enable the tie-in of other discoveries in the same area”, says Ivar Aasheim, senior vice president for NCS field development in Statoil.
Luva concept
The Luva field is planned for development with a Spar platform, which consists of a large-diameter, single vertical cylinder supporting a conventional deck with processing facility, accommodation quarters, etc. The installation is fixed to the seabed.
The choice of concept is in line with the study presented in March 2011. It will be the first Spar on the NCS, and one of the largest of its kind worldwide.
The concept includes two subsea templates with four wells on each and one satellite template with one well. The platform will house accommodation quarters for a permanent crew, a storage unit for condensate, and a gas processing facility with a capacity of 23 million standard cubic metres per day.
NSGI concept
Meanwhile, the Norwegian Sea Gas Infrastructure (NSGI) project has chosen a gas transport concept that includes a 480-km long, 30-36 inch pipeline from the Luva field to the onshore processing facility at Nyhamna.
The pipeline will also be connected on to the Linnorm field and tied in to the Zidane field. In addition, connection to Åsgard Transport via the Kristin platform will be possible, and there are plans for tying in other fields and discoveries.
The concept includes the expansion of the Ormen Lange field’s Nyhamna gas plant with the intention of converting it into a gas terminal.
“NSGI would not only provide gas export solutions for Luva, Linnorm and Zidane, but also contribute in opening up a new gas region on the NCS – making it possible to develop existing and potential future discoveries in the area,” says Statoil project director Håkon Ivarjord.
“NSGI will also take care of gas exports from the Haltenbanken area that exceed the available capacity in Åsgard Transport, thus improving the resource management of the existing fields there.  In this respect NSGI may play an important role in securing the NCS’s position as a long-term, reliable gas province.”
Industrial development
The substantial investments being made on Luva will drive the development of deep-water production in the Norwegian Sea.
The biggest and most long-term spin-off effects will arise during the operational phase, even given the magnitude of the investments during the construction period.
Collaboration with Petro Arctic has been established, as Luva will have a considerable impact on industrial development in northern Norway.
