Natural Gas Leak on Supply Vessel in Gulf
Houma Incident Command received a report of an incident that occurred at about 9:25 a.m. Friday, June 11, involving a supply vessel that was mooring to a natural gas riser platform and pipeline in waters near Cocodrie, resulting in a release of natural gas. Of the 41 people on board, 36 were transported to shore, treated by emergency medical services and taken to five local hospitals. Symptoms ranged from scratchy throats to coughs and nausea. Of those 36 people, two were characterized as more serious, complaining of shortness of breath, disorientation and chest pains. One of those two was airlifted to a local hospital for emergency care. Five crew members are still on the vessel and moving it to a safe mooring, where they will be evaluated by local emergency medical services.
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.
BOEMRE Responds to Report of Natural Gas Leak
The Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) is responding to a report that Apache Corp. has experienced a potential natural gas leak at East Cameron Block 278 Platform B, a natural gas production platform approximately 93 miles offshore Louisiana, south of Lake Charles, in about 173 feet of water. The platform, which has not been in production for nearly a decade, is currently used to process natural gas and condensate from other facilities. According to its report, at approximately 10 a.m., January 16, Apache was in the process of permanently plugging its associated non-producing natural gas wells when workers spotted what appeared to be natural gas bubbling to the surface near the platform.

Shell: Gas Leak Impacts Supplies to NLNG
Shell Petroleum Development Company Limited (SPDC) has declared force majeure on gas supplies to Nigeria LNG, effective 09:00 hrs (Nigerian time) on Wednesday, May 15 2013. This action is due to production deferment following a reported leak along the Eastern Gas Gathering System (EGGS-1) right-of-way (RoW) near Awoba in Rivers State. In line with safety precautions, we have shut down our Soku and Gbaran Ubie gas export via the EGGS1 pipeline. Some 1.5 billion standard cubic feet of gas per day is currently impacted. For a limited time and subject to capacity limitations, SPDC are able to export about 100-200MMscf/d from Soku via the GTS1.
Delayed Production Start at Njord after Gas Leak
Production on the Njord platform was shut down on April 24 as a result of operational problems with gaskets in a gas export compressor. Later the same day, during work to resume production, a gas leak was discovered in one of the risers. All production on Njord was immediately shut down and will remain shut down until the cause of the leak has been determined. Production at the Njord field has been shut down since April 1 as a safety measure, while inspection of risers is carried out after earlier discoveries of internal damage to a particular type of flexible pipe.

Petrobras Stops Platform Output After Gas Leak
Brazil state-run oil company Petroleo Brasileiro SA stopped production on Sunday from its P-40 platform in the offshore Marlim Sul field after a gas leak on the vessel, an oil workers' union said on its website on Monday, citing worker reports. The P-40, a semi-submersible production platform, was producing about 45,915 barrels (7,300 cubic meters) of oil and 800,000 cubic meters of natural gas a day when it was shut down, the union said. The P-40 is at the hub of a network of five platforms in Marlim Sul and at the center of oil and gas pipelines that interlink undersea natural gas pipelines into a single export line to the coast. It is also interlinked to a pipeline system that exports oil from the neighboring Marlim field.
Marad: All Safe After Gas Leak Evacuation
On Sunday evening, a gas leak was discovered in a hot water system servicing Barry and Jones Halls at the U.S. Merchant Marine Academy in Kings Point, New York. Midshipmen and staff on duty immediately evacuated Barry and Jones Halls, which share mechanical systems, and two adjacent barracks. Emergency responders transported thirty-nine midshipmen to local hospitals for evaluation, however no one was admitted. The barracks buildings were ventilated, and a hazardous materials team from the Nassau County Police Department tested the air in the barracks to ensure it was free of carbon monoxide, and that the buildings were safe to reoccupy. Midshipmen were permitted to return to their rooms by approximately 10:30 p.m. Sunday evening.
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.
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.
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.
Offshore Gas Leak in North Sea – Texans on the Way
A team of Texan troubleshooters head for Scotland to prevent a major gas blast in the North Sea, according to a report in the 'Daily Record' newspaper. The giant oil installation was completely sealed off and abandoned after being evacuated following the leak. The shutdown and evacuation is unprecedented in the history of oil and gas exploration off Scotland. The firm running the operation have drafted in a team of Texan “Hellfighters” in a bid to prevent a disaster akin to the Deepwater Horizon catastrophe in the US. Nineteen oil workers who stayed on the Total-owned Elgin platform were airlifted off yesterday. A two-mile air and sea exclusion zone was imposed around the Elgin and the connected Rowan Viking drilling rig 150 miles off Aberdeen.
Offshore Gas Leak – Mobil Explains Reason for the Flare
Flare still burning on the abandonned North Sea Elgin platform – Total Corp. addresses safety question. The flare is an integral part of the platform's safety system. In an emergency it is used to safely evacuate all the gas from the platform. During the incident it performed this task perfectly, allowing everyone to evacuate safely. When the emergency de-pressurisation is initiated, all hydrocarbons feeds are closed and valves are opened on installations vessels to de-pressurise gas to the flare. These valves remain open as they are designed to in such circumstances. The flare is still lit because when the platform is shut down and de-pressurised in an emergency, it cannot be fully purged as done in a controlled shutdown. This is perfectly normal.
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.
Offshore Gas Leak – Experts Board to Evaluate Situation
Total announces that its experts and specialist contractors boarded the Elgin complex and successfully carried out their objective. In an important milestone toward bringing the situation under control, the team spent nearly four hours on the Elgin complex to gather preliminary information that will be used to assist in preparation for deploying the necessary equipment to perform a well control operation. The aim of the reconnaissance mission was to carry out a preliminary survey of the leak area, establish zones which can be safely accessed and gather data on the G4 well.
Elgin Platform Gas Leak – Financial Implications
"From an environmental standpoint, it is important to understand that Elgin is a natural gas and condensate field. It is not an oil field. While we understand the comparisons to Macondo are inevitable, we would like to state clearly that the situations are very different. There is no crude oil involved here, and therefore the current impact on and risks for the environment are relatively low. Let me now give you our current best estimate of the financial implication of the Elgin situation.
North Sea Gas Leak – Total Oil's Update
The 'West Phoenix' drilling rig has positioned itself about 30 metres away from the Elgin complex ready to support the operation to quell the gas leak, which should start very soon. Before moving alongside Elgin, the 'West Phoenix' had been on standby getting ready. Activities on board the rig this week have included: major welding of some key components; deployment of communication transponders; and final testing of essential equipment, such as the dynamic positioning and mist water systems.
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.
