Audit of logistics planning and implementation in the supply chain to and on Transocean Winner

During the period 16-20 October 2006, the Petroleum Safety Authority Norway (PSA) conducted an audit of how Transocean Offshore Ltd. (Transocean) manages technical, operational and administrative aspects of logistics planning and implementation in the supply chain to and on Transocean Winner.


Transocean WinnerThe focus of the audit was on lifting equipment and lifting operations. Among other things, verifications were performed on the Transocean Winner (see photo).

Background for the audit

The audit was a verification activity under the PSA's general project task for logistics and follow-up of lifting operations. The audit focused on the risk associated with materials handling, including lifting operations, as well as the problem areas that emerged in our report "Causal relations for incidents involving offshore cranes".

Purpose of the audit

The purpose of the audit was to verify that safety is ensured through Transocean's management of logistics planning and implementation. Another objective was to verify that technical condition is safeguarded through inspection and maintenance of lifting appliances and lifting gear, and that the follow-up of undesirable incidents involving lifting operations satisfies the relevant requirements.

Result of the audit

The PSA identified four nonconformities in relation to regulatory requirements, as well as some factors with potential for improvement. We would mention the following important findings:

  • Transocean Winner was put into operation without Transocean having a satisfactory overview of the technical condition, the status of maintenance and nonconformities involving the lifting equipment on board.

  • Access to the crane is via a vertical ladder.

  • The training system does not meet all regulatory requirements.

  • The clearance between the crane's fixed and rotating parts is less than the requirement of 600 millimeters.
