Aasta Hansteen, the world's largest spar platform started its journey from 21 April 2017 to make its way from South Korea to the Norwegian sea. Statoil, the Norwegian oil giant, is behind a huge transport project.
Luva gas field, located 300 km offshore in the Vøring area of the Norwegian sea at a depth of 1,300 meters, was first discovered in 1997. The field was later renamed after Norwegian women, a fighter for the rights of the Aasta Hansteen in March 2012. The nearest established infrastructure of the oil field being miles away makes it difficult to extract oil and gas from the area. Harsh weather conditions in deep waters the next challenge.
Luva gas field in combination with Haklang and Snefrid sør called Aasta Hansteen now. The calculations show that 47 billion cubic meters of gas can be extracted from the field as a whole. Gas available in the dry with a low content of carbon dioxide. Only Snefrid sør offers 31-57 million barrels of oil, according to the company.

Statoil has received approval for its plans for development and operation (pdo) by the Ministry of petroleum and energy in 2013. Platform Spar proposed in the PDO-the first installation of the gas infrastructure of its kind in the entire Norwegian continental shelf. The platform weighs in at 70,000 tons, making it the largest spar Platform in the world. "Hyundai heavy industries" (NN), South Korea made the basis of the platform size 200 x 50 metres in diameter and weighing 46,000 tons. According to the twenty-first the description, the spar Platform is “cylindrical, partially submerged offshore drilling and production platform, which is designed for deepwater operations.” Below is a picture of a giant structure that also has provision for storage of condensate, which will be loaded into Shuttle tankers on the field.

Heavy transport vessel Boskalis is called analysis at the forefront of the float of the substructure transport to Norway on a two-month journey around 14,500 nautical miles. A few months later, 25,000 tons of topsides will also reach Norway in combination with the frame. After the structure is assembled, it will be towed to the Norwegian sea, at a depth of 1300 meters in the field Aasta Hansteen. For the first time Norway uses steel catenary risers (SCR) and first used synthetic rope for mooring spread on the shelf. The country will become the first Scandinavian country to install mechanically lined pipe using the reel-lay. According to the plan, gas production should begin in the third quarter of 2017, which was postponed to 2018 due to delay in platform construction.
