Statoil, together with its Luva field partners, has selected a Spar platform to develop the field, which is located outside of existing infrastructure and has a water depth of 1,300 meters (4,265 feet). As a gas transport solution has also been decided, a major step has now been taken towards deep-water production in the Norwegian Sea.
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.—Ivar Aasheim, senior vice president for NCS field development in Statoil
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.
Meanwhile, the Norwegian Sea Gas Infrastructure (NSGI) project has chosen a gas transport concept that includes a 480-km long, 30-36" 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.
The substantial investments being made on Luva will drive the development of deepwater production in the Norwegian Sea, Statoil said. 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.
The Luva discovery was made in 1997, and Statoil has been operator since 2006. Luva is expected to come on stream in 2016; expected recoverable volume is 40–60 billion standard cubic meters of gas. Partners are Statoil (75%), ExxonMobil (15%) and ConocoPhillips (10%).
Statoil has assumed the responsibility for the NSGI development from Gassco and has been assigned operator for the construction phase, while Shell has been assigned responsibility for the modifications at Nyhamna.
Gassco is responsible for the commercial process between the NSGI partners and other infrastructure facility owners, as well as for all pre-operational activities.
Gassco will take over as operator when NSGI is incorporated into Gassled at start-up, which is expected to take place during 2016. The NSGI partners are Centrica, ConocoPhillips, Edison, E.ON Ruhrgas, ExxonMobil, GDF SUEZ, Maersk, OMW, Petoro, RWE Dea, Shell, Statoil and Total.
