Jul 11, 2012 – Noble Energy reported that appraisal drilling will not occur at its Deep Blue prospect at this time. Although hydrocarbons were found in both the initial exploration well and subsequent sidetrack, the company and its partners have decided not to proceed with additional appraisal activities right now. The Deep Blue well was originally spud late 2009 and sidetrack operations were underway when the moratorium was announced. Noble Energy was required to suspend operations and the rig working at that time was released. After the moratorium was lifted, another rig was certified under new regulatory requirements to finish the sidetrack.

Aker Solutions has been awarded a FEED (front-end engineering and design) contract from Statoil to design the world’s largest Spar platform for the Aasta Hansteen field development in the Norwegian Sea.
With a total hull length of 193 meters and a draught of 170 meters, the Aasta Hansteen (formerly named Luva) Spar platform will be the largest of its kind. A Spar platform is a cylinder shaped floating offshore installation. Aasta Hansteen will be the first Spar platform on the Norwegian continental shelf (NCS), and also the world’s first Spar platform with condensate storage capacity – a so called Belly-Spar.
The Belly-Spar concept is an exclusive Aker Solutions design. The ‘belly’ refers to the increased diameter on part of the circular shaped hull, where the condensate storage tanks are located. This gives the Aker Solutions’ Belly-Spar its characteristic shape.
Henning Østvig, head of Front-End & Technology in Aker Solutions says: “The Aasta Hansteen Spar will be the first production platform on the NCS with steel catenary risers. With a water depth of 1300 meters, this is probably the only riser technology that can meet the challenges on the Aasta Hansteen field”.
The steel catenary risers are made of self-supporting steel pipes in a bow shape between the platform and the seabed. The shape helps the risers compensate for the motions on the floating facility.
“The Belly-Spar concept is a result of the innovative spirit and culture among our engineers, who have come up with the right solutions for the challenging conditions on the Aasta Hansteen field,” says Valborg Lundegaard, head of Engineering business area in Aker Solutions.
The mooring system for Aasta Hansteen Spar platform consists of a set of polyester lines. “There are currently no installations on the NCS with polyester mooring. Aasta Hansteen may be the first, and it will definitely be operating in the deepest water,” says Henning Østvig.
The FEED study will be completed in the third quarter of 2012. The contract value is undisclosed.
Aker Solutions’ contract party is Aker Engineering & Technology AS.
