  • Equipment

From 15 to 17 December 2014, the Petroleum Safety Authority (PSA) Norway carried out an audit of the jacket fabrication for Gina Krog. 

The Gina Krog jacket, destined for Statoil’s Gina Krog field development in the North Sea, is under construction at the Heerema yard in Vlissingen, The Netherlands.

According to the PSA, the objective of the audit was to verify that Statoil’s follow-up of fabrication of the jacket was being carried out in compliance with applicable regulations.

The PSA says that as a result of the audit no non-conformities were identified.

However, improvement points were identified in connection with: Post-weld heat treatment (PWHT); Design life; and Documentation.

Gina Krog field

Gina Krog field (previously known as Dagny) is located 30 kilometers northwest of the Sleipner field and approximately 250 km southwest of Stavanger, Norway. The development of Gina Krog will be among Statoil’s major new developments with an estimated 225 million barrels of oil and gas.

The Gina Krog partners submitted a Plan for Development and Operation (PDO) in December 2012. An impact assessment was submitted for consultation in October 2012.

The plan is to develop Gina Krog with a platform resting on the seabed, while the wells will be drilled with a mobile jack-up drilling rig. The liquid will be transported via a tanker, and the gas via the Sleipner field.
