Audit of the drilling systems and maintenance management on Deepsea Atlantic

During the period 8 – 10 October 2008, the Petroleum Safety Authority Norway (PSA) conducted an audit of the drilling systems and maintenance management on the mobile facility Deepsea Atlantic at the DSME shipyard in Goeje, South Korea.


Background for the audit
The audit was related to Odfjell Drilling’s (Odfjell) application for an Acknowledgement of Compliance (AoC) for the mobile drilling facility Deepsea Atlantic (illustration).


Deepsea Atlantic is a mobile drilling facility under construction at the DSME shipyard in South Korea.

The drilling facility is planned to be used for activities on the Norwegian Shelf with StatoilHydro as operator.

The purpose of the audit
The purpose of the audit was to verify that the management and technical aspects of drilling, drilling systems and maintenance management systems on the facility comply with the regulatory requirements. The audit was conducted on the basis of information received from Odfjell Drilling in connection with the AoC application and meetings between the PSA and Odfjell.

The result of the audit
Major work was still ongoing on the facility during the audit. Several of the areas appeared unfinished and there were many items on Odfjell’s punch lists that had not yet been corrected/addressed.

New non-conformities and items of improvement were discovered. These had not been registered by Odfjell, nor had the company submitted an exemption application to the authorities. Moreover, we discovered that one of the submitted non-conformities and exemption applications no longer constituted a non-conformity and could thus be withdrawn. New exemption applications must be submitted in the usual manner for the new non-conformities with the regulatory requirements revealed by the audit.

We were informed of the company’s plan to familiarise and train the crew in the various systems and use of equipment. However, at the time of the audit, this work appeared unfinished and not very specific with regard to drilling and maintenance.

The maintenance management system Maisy was not operative, nor had all the necessary data been entered into the system. Consequently, we could not carry out the necessary verifications in the system with regard to traceability, maintenance programme, criticality, maintenance intervals, priority, etc. This will be done at a later stage, once the data have been entered into the system.
