Audit of marine systems on Bredford Dolphin

The Petroleum Safety Authority Norway (PSA) is currently processing Dolphin AS' application for an Acknowledgement of Compliance (AoC) for the Bredford Dolphin. As part of the consideration process, we conducted a verification on board the Bredford Dolphin at the Remontowa shipyard in Gdansk during the period 21-23 February 2007. We were assisted in this effort by the Norwegian Maritime Directorate. During this audit we identified two nonconformities in relation to the regulatory requirements.


The verification was aimed at load-bearing structures, stability, ballasting, weather and watertight integrity, as well as mooring.

Background for the audit

Bredford Dolphin (kilde: Dolphin)A consortium consisting of Drilling Production Technology AS, Det Norske Oljeselskap AS, Pertra AS, Revus Energy ASA (Norwegian Branch), BG Norge Ltd, Endeavour Norge AS, Lundin Norway AS and Marathon Petroleum Norge AS plan to use the Bredford Dolphin (pictured) for activities on the Norwegian continental shelf under a three-year contract.

During its stay at the shipyard, the Bredford Dolphin has undergone its five-year main classification as well as extensive upgrades including work on load-bearing structures, mooring, stability, ballasting and weather and watertight integrity.

Purpose of the audit

The purpose of the audit was to verify compliance with the prevailing regulations in connection with the ongoing processing for an (AoC).

Result of the audit

During the verification, two regulatory nonconformities were identified in connection with weather and watertight integrity.

There was a great deal of work underway during the verification, and some work was planned but not yet initiated. Little documentation was complete, e.g. analyses, drawings, manuals and procedures. Therefore, we had only a limited opportunity to evaluate the completed facility and the documentation in relation to the current regulations.

Some points regarding documentation are mentioned in comment form. These are issues we have raised with Dolphin in a separate e-mail. Access to relevant documentation is important in connection with our AoC process.
