The U.S. Department of the Interior’s Bureau of Safety and Environmental Enforcement (BSEE), Noble Energy, Inc. and the Helix Well Containment Group (HWCG) announced Tuesday the successful completion of a full-scale deployment of critical well control equipment to assess Noble Energy’s ability to respond to a potential subsea blowout in the deepwater Gulf of Mexico.
BSEE Director James Watson confirmed that the HWCG capping stack deployed for the exercise met the pressurization requirements of the drill scenario, marking successful completion of the exercise.
The unannounced deployment drill, undertaken at the direction of BSEE, began April 30 to test the HWCG capping stack system – a 20-feet tall, 146,000-pound piece of equipment similar to the one that stopped the flow of oil from the Macondo well following the Deepwater Horizon explosion and oil spill in 2010. During this exercise, the capping stack was deployed in more than 5,000 feet of water in the Gulf of Mexico. Once on site, the system was lowered to a simulated well head (a pre-set parking pile) on the ocean floor, connected to the well head, and pressurized to 8,400 pounds per square inch.
“Deployment drill exercises like this one are essential to supporting President Obama’s commitment to the safe and responsible development of offshore resources,” said Director Watson. “BSEE continually works to ensure that the oil and natural gas industry is prepared and ready to respond with the most effective equipment and response systems.”
BSEE engineers, inspectors and oil spill response specialists are evaluating the deployment operations and identifying lessons learned as the bureau continues efforts to improve safety and environmental protection across the offshore oil and natural gas industry.
“The quick and effective response to a deepwater well containment incident, demonstrated during the drill, was enabled by collaborative communication and planning between the industry and regulatory agencies with a focus on solutions-based outcomes,” said John Lewis, senior vice president of Noble Energy. “BSEE, the U.S. Coast Guard, Louisiana Offshore Coordinator’s Office and Noble Energy brought unique perspectives together in a Unified Command structure to achieve a shared goal. Through excellent coordination within the Incident Command System structure that included elevating the Source Control Chief to report directly to Unified Command, the dedication of hundreds of people and activation of the HWCG rapid response system, all objectives were met.”
“HWCG’s ability to quickly and effectively respond to a call from Noble Energy and every operator in our consortium is made possible by a combination of the mutual aid agreement committed to by each consortium member and the contracts we have in place for equipment that is staffed and working in the Gulf each day,” said Roger Scheuermann, HWCG Commercial Director. “Mutual aid enables members to draw upon the collective technical expertise, assets and resources of the group in the event of an incident. Utilizing staffed and working vessels, drilling and production equipment helps ensure there is no down time for staffing or testing equipment readiness in a crisis situation.”
In accordance with the plan, all 15 member companies were activated for this incident through the HWCG notification system.
For the safety of personnel and equipment, a Unified Command comprised of BSEE, the US Coast Guard, Louisiana Oil Spill Coordinators Office and Noble Energy decided to temporarily hold operations May 2 and 3 due to rough weather over the Gulf of Mexico. The safety of personnel remained a top priority throughout the exercise.
Since the Deepwater Horizon tragedy in 2010, BSEE has worked to implement the most aggressive and comprehensive offshore oil and gas regulatory reforms in the nation’s history. This deepwater containment drill tested one critical component of enhanced drilling safety requirements.
Press Release, May 8, 2013: Source
Offshore oil and gas operators in the Gulf of Mexico continue to restore production following Tropical Storm Isaac. The Bureau of Safety and Environmental Enforcement (BSEE) Hurricane Response Team will continue to work with offshore operators and other state and federal agencies until operations return to normal.
Personnel remain evacuated on a total of 10 production platforms, equivalent to 1.68 percent of the 596 manned platforms in the Gulf of Mexico. Production platforms are the structures located offshore from which oil and natural gas are produced.
Personnel remain evacuated from one rig, equivalent to 1.32 percent of the 76 rigs currently operating in the Gulf. Rigs can include several types of self-contained offshore drilling facilities including jackup rigs, submersibles and semisubmersibles.

On February 17, 2012, the Department of Interior’s Bureau of Safety and Environmental Enforcement (BSEE) approved Shell’s Oil Spill Response Plan (OSRP) for the Chukchi Sea.
Approval of the Plan is another major milestone on the path to drilling in the Alaska offshore this summer and further validates the huge amount of time, technology, and resources Shell says it “has dedicated to assembling an Arctic oil spill response fleet second to none in the world.”
Specifically, Shell’s OSRP includes the assembly of a 24/7 on-site, nearshore and onshore Arctic-class oil spill response fleet, collaboration with the U.S. Coast Guard on both assets and response planning, and newly engineered Arctic capping and containment systems that will be tested before drilling commences.
“We recognize that industry’s license to operate in the offshore is predicated on being able to operate in a safe, environmentally sound manner. Shell’s commitment to those basic principals is unwavering. Our Alaska Exploration Plans and Oil Spill Response Plans will continually be guided by our extensive Arctic expertise, solid scientific understanding of the environment and world-class capabilities,” said Pete Slaiby, VP Alaska.
Consistent with new regulatory requirements implemented in the wake of the Deepwater Horizon oil spill, Shell was required to prepare for a worst case discharge nearly five times that of their previous plan, to include planning for adverse weather conditions, and to develop special equipment and strategies that could respond to a loss of well control and a spill.
Shell has committed to provide for the following emergency contingencies: (1) the availability of a capping stack to shut off any flow of oil if other shut-off systems fail; (2) the capability to capture and collect oil from that stack; and (3) access to a rig capable of drilling a relief well that could kill the well, if necessary. The ready availability of a capping stack and an oil collection system are new commitments that apply lessons learned from the Deepwater Horizon tragedy to offshore oil and gas production activities.
Shell has proposed drilling up to six wells in the Chukchi Sea during the next two summer open water seasons within the Burger Prospect, located about 70 miles off the coast in approximately 140 feet of water.
“After an exhaustive review, we have confidence that Shell’s plan includes the necessary equipment and personnel pre-staging, training, logistics and communications to act quickly and mount an effective response should a spill occur,” said BSEE Director James A. Watson. “Our staff will maintain vigilant oversight over Shell to ensure that they adhere to this plan, and that all future drilling operations are conducted safely with a focus toward spill prevention.”
The approval issued Friday does not authorize Shell to begin drilling; Shell must still seek and obtain approval from BSEE for well-specific drilling permits prior to commencing operations, and BSEE would inspect and approve equipment that has been designed and deployed for the effort, including Shell’s capping stack, before activities could go forward.
Shell has also filed a OSRP for operations in the Beaufort sea. “The Beaufort Oil Spill Response Plan has been filed and is still being reviewed. It’s our understanding that review will be complete in the near future.” said Shell in a statement.

The Bureau of Safety and Environmental Enforcement gave the permit to Murphy Exploration & Production Co., allowing the firm to drill a sidetrack well at its Thunder Hawk field about 150 miles southeast of New Orleans.
Other companies have successfully submitted oil spill response plans that would rely on the capping stack developed by Helix Well Containment Group or a separate system devised by the Marine Well Containment Co. But Murphy is the first firm to win regulators’ sign off for an emergency response plan involving Helix’s full flowback system.
The cap-and-flow system caps the well and contains any additional flowing oil in case it is out of control. The entire system involves a capping stack installed on the well head and a flowback system designed to direct the crude to vessels floating overhead.
Although some wells require only the containment system, the cap-and-flow equipment is geared toward operations with higher pressure. Regulators say the cap-and-flow program can help maintain the integrity of an underwater well in cases where the capping stack alone might not do the trick.
The Helix cap-and-flow system is capable of sending 55,000 barrels of oil and 95 million cubic feet of gas per day to the floating ships.
Separately, Helix is asking the Obama administration for a license to provide its containment equipment in case of a spill from offshore drilling in Cuban waters. The Spanish company Repsol is set to begin drilling a deep-water exploratory well north of the island nation — just 50 miles from south Florida — in December or January.
Helix spokesman Cameron Wallace said the ultimate scope of services that would be offered is still under consideration “and no firm commitments have yet been made.”
“We believe that it is important to make proven solutions, similar to our Helix Fast Response System, available for any drilling project that could potentially impact the nation’s coastlines,” Wallace said. “Helix’s goal is to make some of these spill containment technologies available while fully complying with federal trade regulations.”
