The Snøhvit gas field in the Barents Sea has started production. The Snøhvit project is the first gas development in the Barents Sea and also involves the construction of the first LNG plant in Arctic conditions. Snøhvit also represents the first large-scale LNG project in Europe.

There are no above-surface platforms or floating production units for Snøhvit—all the field work and CO2 injection is done by subsea installations, remote-controlled from shore.

Statoil, which holds a 33.53% interest, operates the project. Other shareholders are Petoro (30%), Total (18.4%), Gaz de France (12%), Hess (3.26%) and RWE-DEA (2.81%).

Natural gas produced offshore in water 310-340 meters deep on the Snøhvit field is sent onshore through a 143 kilometer multiphase pipeline to a 4.2 million tonnes per year liquefied natural gas (LNG) plant at Melkøya, near Hammerfest, in northern Norway, where it is processed. The LNG will be shipped to European and US markets. Approximately 700,000 tonnes per year of CO2 will be captured from an estimated total 860,000 tonnes per year produced and be re-injected in a Snøhvit field reservoir.

Contractual LNG deliveries are scheduled to start in the fourth quarter of 2007. Gas production is expected to ramp up to a plateau in 2008 of nearly 5.7 billion cubic metres per year (550 million cubic feet per day). Nearly 23,000 barrels per day of condensate and liquefied petroleum gas (LPG) will also be produced at plateau in the Melkøya plant.

According to USGS estimates, some 25% of the remaining petroleum reserves are in the Arctic region. North Africa, the Caspian Sea and the Middle East account for another 50%, and the remaining 25% is scattered across the rest of the world.

This field is at the edge of the Norwegian Sea, not the Barents Sea. The Russians have just laid claim to oil & gas resources in the Arctic, let's not just roll over and hand them all to Vladimir Vladimirovich on a silver platter.

Guess why the Norwegians are expanding their Navy...

They don't like Vladimir Vladimirovich more than any of us do.

Deepwater Structures Inc (DSI) has developed an arctic class floating unit that can do round the year operation in the arctic deepwater with minimum risk. The vessel has exceelent naval architecture and vessel technology to break ice sheets of 2-4m thick and ridges of 25 m deep and could survive in severe winter and summer strom. It has heav natural period of 23 s and storage capacity of 1.4 million oil or equivalent LNG. It has top side load capacity of 25,ooo mt. The vessel technology is the state of the art in the industry and DSI is the leader in the floating technology in the world. DSI could be contacted by email NS@dsi-engr.com and or naganus@yahoo.com. DSI is located in Houston, Texas, USA.
