Aaasta Hansten

South Korea-based shipbuilder and offshore facilities contractor Hyundai Heavy Industries (HHI) has received a $1.1bn order from Statoil to develop a topside facility for installation on the Aasta Hansteen spar hull in the Norwegian Sea.

As part of the contract HHI will develop the 21,000-tonne topside facility, which will have the capacity to produce 23 million cbm of oil and gas per day.

Upon its completion, which is likely to be in 2016, the facility will be installed at the Aasta Hansteen field, located 300km off the coast of Norway.

As a floating installation, the spar will include a vertical column tied to the seabed, plus conventional topsides with processing facilities. Statoil will use pure steel risers to supply gas from the seabed to the platform and further to Polarled.

"The facility will be installed at the Aasta Hansteen field, located 300km off the coast of Norway."

The platform’s hull will feature storage for condensate, which will be loaded to transport tankers at the field. Once it becomes operational, the cylindrical platform, measuring 195m in total hull height, will be able to store 160,000 barrels of condensate.

HHI will construct the offshore facility with support from CB&I in The Hague, Netherlands and European suppliers under the NORSOK standard.

In early January 2013, Statoil submitted a plan to the Ministry of Petroleum and Energy for the development and operation (PDO) of the Aasta Hansteen field.

The company is expected to invest a total of NOK32bn ($5.7bn) to develop the field, which is located outside established infrastructure at water depths of 1,300 metres.

Hyundai Heavy Offshore and Engineering Division chief operating officer Kim Jong-do said: "I believe our long experience in the offshore facility field will continue to give us an edge in winning orders from the Middle East, Australia, West Africa and the North Sea."
