Audit of working environment follow-up on Alvheim FPSO

During the period 24-25 April 2007, the Petroleum Safety Authority Norway (PSA) conducted an audit of how the working environment is followed up on the Alvheim mobile production facility (FPSO). Our main impression regarding follow-up of the working environment on the facility is generally positive.

At the time of the audit, the Alvheim FPSO was under construction and commissioning at the Aibel shipyard in Haugesund. The audit was part of the process linked to Maersk Contractors Norge AS' (MCN's) application for an for the facility.

Background for the audit

The Alvheim FPSO is a former tanker (then called the MST ODIN), which the operating company, Marathon Petroleum Company Norway (MPC(N)), is rebuilding into an FPSO. MPC(N) has applied for consent to use the facility on the Alvheim field. MCN will operate the facility in the production phase, and has applied for an AoC for the facility.

The audit was a further follow-up of a previous working environment audit conducted at Keppel Shipyard Ltd in Singapore in connection with the rebuilding activities involving the Alvheim hull (link).

Purpose of the audit

The purpose of the audit was to verify compliance with current requirements regarding working environment conditions on the facility. Another objective was to follow up factors where MCN wanted to apply for exceptions from the prevailing regulations, and to verify the players' plans for implementing outstanding working environment activities.

Result of the audit

The main impression as regards follow-up of the working environment on the facility is generally positive. The project has good control over nonconformities and is making a serious effort to improve these conditions insofar as possible. Access to equipment for operations and maintenance purposes is largely well-arranged in most of the work areas.

Facilitation of future material transport within the individual modules was good. However, material transport with the aid of deck cranes was difficult in several locations due to extensive use of blind lifting and various obstructions on which the load can get caught around loading areas and when lifting through deck hatches.

The upper vessel deck represents an area where access conditions are particularly difficult. In this area, access factors did not receive adequate attention during the engineering phase. Work is underway in consultation with representatives of the various employee groups to install "temporary access solutions" which can partly compensate for some of the hazards.

Because of the project's commissioning status, it was not possible to verify working environment factors linked to chemical handling, lighting, noise, HVAC/indoor climate and safety signs.

We have requested that the project provide plans to verify these working environment factors, including an indication of the timing.
