The audit was carried out in the form of a meeting at MON and focused on MON’s planning of activities in connection with the upcoming drilling of exploration well 6406/3-9 ”T-Rex” with the Transocean Winner mobile facility. The audit was part of the PSA’s processing of the company’s application for consent to this activity.
The objective of the audit was to investigate the company’s compliance with requirements related to management of health, safety and the environment. The PSA based the audit on MON’s application for consent to carry out the drilling activity, and had requested supplementary presentations of some key elements from the company in connection with the application.
This audit focused on management-related elements at an aggregated level. MON’s presentations clarified our selected items in a good manner.
Based on the information uncovered in the audit, the PSA has not identified any nonconformities as regards the petroleum regulations.
MON has established a combined HSE and Audit plan for the upcoming drilling activity, so the connection with the company-established KPIs is clear.
The planned well is in a familiar area, and experience databases have been utilised for nearby wells and reservoirs. The company has used Maersk UK for peer review/QA for its pressure prognoses.
During the operation phase of the activity, MON will use both own employees and supplement with personnel from the company’s technical expertise in the parent company.
As a follow-up after the Macondo accident, Maersk has had internal processes to assess the need for changes to own procedures, and they have identified 24 items for further follow-up.
During the rig acceptance process they have cooperated with the other users of the rig, Lundin, Talisman and Marathon. MON has had access to Lundin’s report following rig acceptance, but will most likely conduct its own independent assessments and verifications. The company believes Transocean Winner has good safety statistics and performance. MON has its own rig acceptance process, and they will thus use a separate template for this, developed by the group. The company also has access to a report from offshore verification carried out by Marathon in October 2010.
The PSA called attention to recent incidents connected to lifting operations on the drill floor, particularly as regards the use of various types of lifting equipment, including bailers/elevators.
MON wants to assume the contractual liability vis-á-vis suppliers and sub-contractors, but they would like to use the same companies as the previous operators to ensure continuity. In the work to create a good understanding of HSE on board, the companies have been involved to arrive at a joint Risk Awareness, and they have positive experience with this.
As regards preparedness, MON would like to use OFFB as their second line preparedness. Based on their presentations, MON appears to have a good structure for defining responsibility and tasks. MON is planning three table-top exercises and two full-scale preparedness exercises before commencing drilling operations.
It is our impression that MON plays an active part in the multipartite cooperation and takes its supervisory duty vis-á-vis Transocean seriously.
No nonconformities were identified during this audit.
