Gas Leak News

Gas Leak Closes Visund Platform

A major natural gas leak shut down the Norwegian Visund offshore oil and natural gas platform, AP reported. No one was injured in the incident, but 17 of 91 crew members aboard were flown to a nearby North Sea platform by helicopter as a precaution when gas and fire alarms sounded. It was a major leak, but that strong winds kept the gas away from the platform itself. Gas leaks on offshore platforms can cause catastrophic explosions and fires, often far from shore, and the agency said it was investigating the incident. Visund was the sixth Statoil-operated field suffering problems this week. The total lost production is 250,000 barrels per day of oil and condensate, also called light oil, and about 50 million cubic meters of natural gas.

Platform Shut Down after Leak

A small natural gas leak on the Statfjord A offshore platform shut down 160,000 barrels per day of Norwegian oil production on Feb. 14. The leak was quickly traced to a small hole in a water pipe, and that production was expected to resume within 24 hours. Any gas leak on an offshore platform can lead to catastrophic explosions and fires if ignited. The leak shut down the 30,000 barrel per day Statfjord A platform as well as the linked 130,000 barrels per day Snorre A platform. The majority of the 244 crew aboard Statfjord A took to their lifeboats as a precaution, and remained there for about two hours until the situation was clarified. There was no need to evacuate.

Sonardyne Launches Leak Detection Sonar

Sonardyne International has announced the launch of an Automatic Leak Detection Sonar (ALDS) at the Oceanology International Exhibition and Conference in London. The Sonardyne product is an active sonar capable of detecting and localizing deep water hydrocarbon leaks around offshore installations and pipelines soon after they develop, allowing operators to respond immediately and accurately in the case of a leak.ALDS is designed to detect oil and gas leaks at significant ranges, allowing coverage of wide areas from a single sensor. Typically, in deep water, the system will detect gas leaks of 1bpd (barrel per day) at a range of 500m and live oil leaks of 10bpd at the same range.

Offshore Rig Gas Leak Kills Two

Two Brazilian maintenance workers died as a result of a toxic gas leak at an offshore oil rig operated by the state oil firm Petrobras. "The workers died when doing maintenance work on a drainage tank at the B-37 platform on the Marlim block in the Campos basin on Wednesday evening," said a Petrobras spokesman, adding that the workers were employees of Ultratec engineering firm. He said it was yet unclear how the leak had occurred and what gas caused the deaths. There were no other casualties and there was no damage to the platform. "The leak was stopped at the same moment on Wednesday. A Petrobras commission is investigating the case." Campos Basin accounts for nearly 80 percent of Brazil's overall crude oil output.

Offshore Gas Leak – Union Calls for Evacuation of More Platforms

High pressure gas leak from North Sea oil rig off coast of Scotland – union expresses safety concerns about gas cloud Oil and gas union leaders have called for all platforms within a five-mile radius to be evacuated after fears the gas cloud may be travelling in their direction, according to a report in Scottish local newspaper 'The Press and Journal' As a direct result of the risk the gas leak poses to its staff on nearby platforms, Shell has also suspended production on the Shearwater and Noble Hans Deul drilling rig. Unite union regional officer for offshore workers, Wullie Wallace, said other platforms should follow suit for a greater focus on health and safety offshore.  

Safety Officials to Investigate Gas Leak at North Sea Platform

The PSA has decided to conduct an investigation due to, among other factors, the significant potential of the incident. The leak occurred in connection with valve testing on the drilling, production and accommodation facility HMP1 on the Heimdal field. It has not yet been determined how much gas leaked out, but the gas leak was substantial and resulted in a serious situation on the facility. There were 98 people on the facility when the leak was discovered. No one was injured in the incident. The purpose of the investigation is to ascertain the course of events and identify trigger factors and underlying causes. The investigation will result in a report which will be published at www.ptil.no.

Hammerfest LNG Production Resumes After Leak

Snøhvit

Production at Hammerfest LNG Production from the Hammerfest LNG plant has been resumed after a gas leak Sunday night. "We started run-up of the Hammerfest LNG plant Tuesday night, and the plant has now reached stable operation. All necessary repairs on the plant have been completed to ensure a safe and efficient start-up," says Knut Gjertsen, head of Snøhvit operations. The Hammerfest LNG plant was shut down Sunday night due to a gas leak in the processing facility. In connection with the plant run-up a condensate leak occurred which required extra time for the start-up preparations.

Offshore Oil Drill Platforms Evacuated After Gas Leak

High-pressure gas leak from North Sea oil rig leads to evacuation, maritime exclusion zone BBC News reports that gas leaking from Total's Elgin PUQ platform, about 150 miles off the coast of Scotland has led to the evacuation of workers and a  2-mile exclusion zone has been set up around it. Two more nearby platforns have also been evacuated. Total E&P UK (TEP UK), which operates the platform, said it was taking "all possible measures" to try to identify the source and cause of the leak and to bring it under control. It has been confirmed that there is a sheen on the water near the platform.  

North Sea Platform Gas Leak – Source Identified

The leaking hydrocarbons are believed to be coming in the well from a rock å which is above the producing reservoir of the Elgin field. The volume of this gas ingress is therefore difficult to estimate. Reports from Oil Spill Response (OSRL) surveillance flight indicate that the gas cloud is still stable and is heading away from Elgin facilities. Total confirms that the gas leak remains ongoing although the situation is currently stable. The precise cause of the gas leak is still being investigated and efforts continue to focus on bringing it under control.

Autronica Highlights Gas Detection for Dual Fuel LNG Vessels

With the number of vessels using dual fuel/LNG propulsion systems growing steadily, Autronica Fire and Security is focusing on the importance of gas detection in this sector during Nor-Shipping 2013. LNG as a fuel can provide lower bunkering costs and emissions, in addition to less wear on engines, however, LNG propulsion systems must be monitored by reliable gas detection technology to ensure safety of crew and vessel should a failure occur. Autronica offers a dedicated Direct Gas Sampling system for LNG powered vessels, which can be specified in parallel to its fire safety systems, such as AutroSafe 4 and Autroprime. This approach ensures that owners and yards have a single source for all fire and gas detection systems for LNG powered vessels.
