Project Profile
Value: US$4,000 million
Location: Hammerfest, Norway
Start-up Year: 2018
LNG: 4.3 million tonne/year
Statoil\'s planning for a second LNG train has run parallel with work to complete Train 1. The Tornerose discovery has large volumes of natural gas; however the partners wanted to find more gas, before committing to a second train. Statoil has already started planning to expand the site at Melkoya. The Snøhvit LNG project was constructed to exploit the resources of three gas fields in the Barents Sea: Snøhvit, Albatross and Askeladd (250m to 345m deep), which lie about 140km northwest of Hammerfest in Norway. These fields, which were first discovered in the 1980s, have estimated reserves of 193 billion cubic metres of LNG and 17.9 million cubic metres of condensate and 5.1 million tonnes of natural gas liquids (NGL). The Snøhvit and Albatross fields came onstream in 2007, while the Askeladd is due to come onstream in 2014-15.
The gas production system is one of the first in Europe to use a subsea production platform, which feeds gas via 143km of pipeline with multiphase flow to a 4.2 million tonnes a year LNG processing plant on Melkøa Island near Hammerfest. The project also has a carbon dioxide capture and storage facility located 2.6km beneath the seabed of the Snøhvit field and a 153km pipeline for reinjection. The facility can store 700,000t of carbon dioxide annually. The project was led by Statoil as part of a consortium of eight companies. The consortium consists of Statoil (33.53%), Petoro (30%), TotalFinalElf (18.4%), Gaz de France (12%), Amerada Hess (3.26%) and RWE-DEA (2.81%). The management, engineering, procurement and construction contract (€380m) was awarded to Linde AG for the provision of key equipment for the LNG terminal. The instrumentation for the facility was supplied by Parker Instrumentation. Aker Kvaerner was awarded a contract in early 2005 (worth an estimated Nkr1bn) for important completion work at the LNG facility at Melkøya Island.
This contract involved Aker Kvaerner Elektro (for electrical and instrumentation installation), Kaefer IKM for scaffolding, insulation and surface treatment and Aker Stord for management of this section of the project which involved installation and integration of the liquefaction / process equipment into the island infrastructure. Aker Stord was awarded the main hook-up and installation contract on Melkøya Island in 2003 and was awarded the contract for preparing the infrastructure and equipment on the island. Aker Kvaerner employed over 800 personnel working on the island over the first half of 2006 so that the project could be completed on schedule. DYWIDAG Systems International (DSI) was responsible for the supply and installation with stressing and grouting of a total of 1,650t horizontal and vertical DSI post-tensioning tendons with accessories in the construction of the tanks to allow them to withstand the extreme conditions.
