Statoil, together with its Luva field partners, has selected a Spar platform to develop the field. As a gas transport solution has also been decided, a major step has now been taken towards deep-water production in the Norwegian Sea.
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.
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 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.
