Gullfaks B platform: Answers Wanted

Norway’s Petroleum Safety Authority Norway, PSA, platform  has identified serious deficiencies related to planning, approval and execution following a gas leak at Norway’s Gullfaks B platform on 4 December 2010. Based on this event and earlier incidents on Statoil-operated installations, the PSA has asked Øystein Michelsen, the company’s executive vice president for development and production Norway, to assess which measures he considers necessary in light of the identified deficiencies.

The gas escape on Gullfaks B occurred in connection with leak testing after maintenance work on a production well. The gas derived from a volume trapped between the downhole safety valve and the Xmas tree. It proved impossible to operate the emergency shutdown valves on the well. Continue reading »

Transocean's Deepwater Horizon - be prepared says the PSA

r a review of initial analyses and reports from the Deepwater Horizon incident. This work is being coordinated by the OLF at the request of the PSA.

The industry’s need to assess the validity of emergency response principles for halting a possible subsea blowout in Norway was stressed by the PSA on 15 June in a letter to the OLF.

In addition, the industry association was asked to evaluate existing strategies for limiting the volumes discharged from a blowout while it is under way.

That would also mean identifying possible improvements in the form of new practices, development of technology and/ or a revised understanding of preparedness requirements. Continue reading »

With 26 collisions in 10 years between offshore facilities and visiting vessels on the Norwegian shelf, six with very large hazard potentials, Norway’s Petroleum Safety Authority, has said enough is enough. The Petroleum Safety Authority Norway (PSA) believes training and organisational factors should receive more attention, while at the same time, the technical failure rate must be reduced.

The audit targeted the establishment of an emergency preparedness organisation and the facility’s technical emergency preparedness solutions.

The activities were carried out through interviews of relevant personnel and verifications on board the facility.

The audit was related to BP Norge’s (BPN’s) future application for consent to use Skarv FPSO. During the audit, the facility was undergoing commissioning at the shipyard in South Korea. The plan is to start activity on the Norwegian continental shelf in 2011 with this facility. Continue reading »

Transocean Leader, key personnel did not understand the risk management system used onboard.

Deepwater Horizon owner Transocean has come under pressure from Norway’s Petroleum Safety Authority following an audit covering the company’s management of major accident risk and handling of barriers. In addition to some 14 non-conformities ranging from inappropriate headoffice directives to firefighting and lifesaving equipment the PSA found that manager were not familiar with the risk management methodology it recently introduced.

Transocean is  implementing a Bow-tie methodology which illustrate hazardous situations and probability-reducing barriers on one side, and consequence-reducing barriers following incidents on the other side of a diagram that resembles a bow-tie.

On the Transocean Leader facility, the PSA verified Transocean’s management and knowledge of major accident risk by reviewing two major accident scenarios in the form of ”table-top” exercises related to the facility’s defined hazard and accident situations.

Says PSA: “The audit activity was well-organised by Transocean”

Transocean’s main management defined which defined situations of hazards and accidents, DFUs, can primarily trigger major accidents. Currently there is not a complete overview of the operational and organisational barrier systems, and the company lacks a systematic approach in the area..

Big Orange, big Crunch

Big Orange XVIII hit the water injection facility Ekofisk 2/4-W on 8 June 2009 with six times more energy than the facility was designed for, says a report from Norway’s Petroleum Safety Authority, PSA. The incident occurred because the autopilot on Big Orange had not been cancelled before it entered a 500 metre exclusion zone and so did not respond to course alterations input by the officer of the watch and Ekofisk Radar operators did not adequately monitor the vessel’s movements inside the exclusion zone and passed no warning to the vessel.

Freefall release fears shut platform

Problems with freefall lifeboat releases have led to the shutdown of the StatoilHydro-operated Kristin platform off Norway. Investigations are underway both by Statoil and Norway’s Petroleum Safety Authority, PSA..

In December last year a freefall lifeboat on the Veslefrikk B platform failed to launch as part of an operation to replace the lifeboat. The release hook required lubrication and several movements before it would function.

Further hook release problems arose with the new freefall lifeboat when fully laden.

The same type of Umoe-Schatt Harding FF1000S had been installed on the Kristin platform. Staffing on the platform has now been cut from 90 to 16 following similar hook release problems in mid-December.

Last year, a freefall lifeboat of similar design on Veslefrikk B suffered damage when launched during a test, again leading to a platform shutdown, revealing design flaws. Three freefall lifeboats were taken out of service. In a meeting with the PSA, Statoil expressed doubt “concerning the quality of these lifeboats as a means of evacuation during all types of weather conditions.”.
