320px-Melkøya-2006Norway’s Petroleum Safety Authority Norway (PSA) has ordered Statoil Petroleum AS to why the company ignored a decision by the PSA that its camp at Melkøya, Finnmark, Norway, should not be used during planned shutdowns at Hammerfest LNG. The order is legally binding.

On 20 February 2013, Statoil received consent to use the accommodation camp in connection with planned shutdowns at Hammerfest LNG at Melkøya, once the facility had been shut down and depressurised. The consent applies up to 31 December 2017. In December 2013, Statoil applied for consent to also use the accommodation camp during the decommissioning and recommissioning period in connection with the planned shutdown in May/June 2014, when the facility was not depressurised. The application was rejected by the Petroleum Safety Authority Norway in a decision of 6 February 2014. Continue reading »

Norway’s Petroleum Safety Authority Norway, PSA, has notified Statoil of an order after its investigation of a hydrocarbon leak on Heimdal on 26 May 2012. The leak is described as among the most serious for several years on the Norwegian Continental Shelf.

The report identifies serious non-conformities from the regulations which are significant for safety. PSA wants Statoil to confirm that “a lack of effect” is not present on other Statoil platforms.

The hydrocarbon leak occurred in connection with the testing of two emergency shutdown valves (ESDVs) on Heimdal’s HMP1 production, drilling and quarters platform.

To prepare for the test, a pipeline was to be depressurised to the flare. This contained a ball valve with a 16-bar pressure class as the final barrier against the flare. Because it was closed, the valve experienced a pressure of 129 bar.

Gas leak
The pressure caused the seal in the valve flange to fail, resulting in a gas leak estimated at 3 500 kilograms. The initial leak rate was 16.9 kilograms per second (k/s). Gas was detected across a large area of the installation.

This leak ranks among the most serious gas emissions on the Norwegian continental shelf (NCS) for several years. See the RNNP reports on trends in risk level in the petroleum activity for 2001-11. Continue reading »

Norway’s Petroleum Safety Authority, PSA, is hauling Statoil over the coals regarding the safety of lifting operations following investigation of a potenially lethal incident involving a ‘dropped object’ weighing 23 tonnes.

The lifting incident on Njord A on 18 December 2010 could,  says the PSA, “under insignificantly altered circumstances, have resulted in loss of life and significant material damage.”

PSA Demands Answers On Gullfaks B Gas Leak

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 »

Only Chance Prevented North Sea Blowout Amid 2009 Spill Worries

Only chance averted a sub-surface blowout or explosion, and prevented an incident from developing into a major accident says Norway’s Petroleum Safety Authority. The comment, following an audit of a loss-of-control incident in May, 2010, comes at a time of increasing concern over hydrocarbon leaks and well control incidents during 2009.

The PSA calls the incident, which involved the lengthy loss of a barrier  at Statoil’s Gullfaks C platform, “very serious” and says planning for the drilling and completion operation on well C-06A featured serious and general deficiencies.

Earlier in November the authority presented a report showing that both acute crude oil spills from petroleum operations on the Norwegian continental shelf and near misses for such incidents have fallen sharply since 2001.

But the RNNP report from the Petroleum Safety Authority Norway (PSA) on acute discharges in 2001-2009 expresses concern at the rise in hydrocarbon leaks and well control incidents during 2009.

The results of the study, which builds on the PSA’s on-going survey of trends in risk level in Norway’s petroleum activity (RNNP), were presented to the Safety Forum on 18 November.

Coinciding with the PSA report the Australian government has released its investigation into the PTTEP Montara disaster in August last year.

Says Matin Ferguson, minister for resources and energy: “The fact is that we were lucky with Montara – no lives were lost, there were no serious injuries and the quick, coordinated response from governments, regulators and industry meant that the impact on the marine environment was minimal… Montara was the first major loss of well control in 25 years of safe offshore petroleum operations”.

The Montara report contains 100 findings and 105 recommendations, which have implications for governments, regulators, and the offshore petroleum industry. The Australian government proposes accepting 92, noting 10, and not accepting three of the Report’s recommendations.

Rogaland county public prosecutor has notified Statoil has fined Statoil NOK 25 million ($4.2) following the oil leak from the Statfjord A loading buoy on 12 December 2007.

“We have noted the public prosecutor’s decision,” says Thorstein Hole, vice president for the operations west cluster in Statoil. “We’ll be taking time to study the grounds for the fine.”

Extensive improvements have been implemented after the accident on the North Sea field, he reports. Continue reading »
