Kristin is a gas and condensate field located in the south-western part of the Halten Bank in the Norwegian Sea. Discovered in 1996, and located almost 5 000 metres below ground, the reservoir ranks as the highest pressure and highest temperature field ever tapped on the Norwegian continental shelf – at 13,195 psi (910 bar) and 338°F (170°C).
The first HPHT (high pressure, high temperature) gas floater, and delivered on time, in March 2005.
The field has been developed with 12 production wells in four subsea templates, tied back to a semi-submersible production platform.
On the production platform, Aker Solutions delivered the engineering, procurement, construction and hook-up (EPCH). This contract covered design and fabrication of the deck, process facilities and utilities – and all module hook up. This was the first HPHT (high pressure, high temperature) gas floater, and was delivered on time, in March 2005.
The Kristin semisubmersible is a proof of the strength of Aker Solutions’ project execution model and construction methods, together with planning, procurement and information management methods and system tools. Says Bård Heimset, who was Statoil’s project director for Kristin, “Aker Solutions have reason to be proud of their project execution model. We are generally satisfied with project execution. They have shown again that they are professional in handling these major tasks.”
For the subsea system, Aker Solutions delivered the engineering, procurement and construction (EPC) of the equipment, including four templates, wellheads with christmas trees and control systems, umbilical and associated installation equipment.
Kristin is operated by Statoil, and is currently producing 10 million cubic metres of gas per day. Daily production capacity from the field is 125 000 barrels of condensate and just over 18 million cubic metres of rich gas.
