The Petroleum Safety Authority Norway (PSA) has found no irregularities after an audit of the Deepsea Bergen drilling rig in respect of structural safety.
On September 21 and 22, 2015, the PSA carried out an audit of Odfjell Drilling’s ‘Deepsea Bergen’ while it was at the Aibel Haugesund yard.
According to the PSA, the audit was focused on Odfjell Drilling’s management of hull inspection, verification of the lifetime of structures and findings made during the layover.
The auditor said that this was in continuation of the audit’s first part carried out in June 2015, when the PSA had inspected the onshore organisation of Odfjell Drilling in the domain of structural safety. The objective of the audit in June was to verify that Odfjell Drilling has good systems for the verification of structural and maritime systems, especially focused on inspection findings and ageing.
The purpose of the audit conducted in September was to see how Odfjell Drilling, as the rig owner, was ensuring the safety of ageing facilities that have received an Acknowledgement of Compliance (AoC), in terms of ageing mechanisms and modifications, and how learning from identified ageing mechanisms and factors in previous incidents are used with respect to the structural safety of Deepsea Bergen, the PSA says.
No non-conformities or improvement points were identified during this audit.
Deepsea Bergen is a semi-submersible drilling rig built in 1983 and it is owned by Odfjell Drilling. The rig is on a long-term contract with Statoil and most recently it has been used for activities for Statoil at the fields Skuld, Åsgard and Heidrun.
