Ormen Lange (gas Field) - Technical Description

Technical Description

The Ormen Lange field has been developed without using conventional offshore platforms. Instead, 24 subsea wellheads in four seabed templates on the ocean floor are connected directly by two 30 inches (762 mm) pipelines to an onshore process terminal at Nyhamna. After processing, the gas is exported by the world's second longest subsea gas pipeline - Langeled pipeline - approximately 1,200 kilometres (750 mi) from Nyhamna to Easington in England. The northern section of the export pipeline has a diameter of 42 inches (1,067 mm), and the section from Sleipner to Easington has a diameter of 44 inches (1,118 mm). The field produces 70 million cubic meters of natural gas per day.

Total cost is estimated to reach 66 billion Norwegian kroner (around US$12 billion) by the time of completion.

Famous quotes containing the words technical and/or description:

    I rather think the cinema will die. Look at the energy being exerted to revive it—yesterday it was color, today three dimensions. I don’t give it forty years more. Witness the decline of conversation. Only the Irish have remained incomparable conversationalists, maybe because technical progress has passed them by.
    Orson Welles (1915–1984)

    Do not require a description of the countries towards which you sail. The description does not describe them to you, and to- morrow you arrive there, and know them by inhabiting them.
    Ralph Waldo Emerson (1803–1882)
