Ormen Lange is a natural gas field on the Norwegian continental shelf. It is situated 120 kilometres (75 mi) northwest of Kristiansund, where seabed depths vary between 800 and 1,100 metres (2,600 and 3,600 ft). The field is named after the famous longship Ormen Lange of Olaf Tryggvason, a 10th-century Viking king of Norway.
The field was discovered in 1997. Production began in September 2007. The King of Norway attended the official opening of this project, delivered on time and inside budget, on 6 October 2007, at the football stadium in Molde.
The reservoir is approximately 40 kilometres (25 mi) long and 8 kilometres (5 mi) wide, and lies about 3,000 metres (9,800 ft) below sea level. Recoverable gas reserves are estimated to be ~300 billion cubic meters.
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.
The onshore facility at Nyhamna was designed by Aker Solutions Engineering in 2003-2007.
