NEW ORLEANS – Bureau of Safety and Environmental Enforcement (BSEE) preparedness analysts and engineers recently conducted a virtual government initiated unannounced exercise (GIUE) in the Gulf of Mexico.

GIUEs test an operator’s ability to timely employ its incident management team and execute its oil spill response plan.

Eric Miller, chief of the BSEE Oil Spill Preparedness Division, said: “BSEE plans and executes these no-notice exercises to witness and evaluate an oil spill response plan holder’s ability to employ public and private equipment, resources, and staff to respond to a hypothetical oil spill. GIUEs are a critical tool for BSEE to gauge current response plans and capabilities.”

The exercise required the operator, Empire Midstream LLC, to respond to a simulated oil spill from one of its pipelines traversing through Grand Isle block 110, about 60 mi (97 km) offshore Louisiana. The drill simulated that a helicopter pilot reported a sheen from an unknown source, described as 1.5 mi (2.4 km) long by 0.5 mi (0.8 km) wide, with a 70% silvery and 30% rainbow coloration.

All response actions other than the regulatory notifications were simulated, and the exercise evaluated the ability of the company to quickly mobilize a staff and effectively coordinate a response. According to BSEE, the goal was to effectively identify and protect shoreline and sensitive resources, create a spill trajectory forecast, and develop a plan for securing the source.

John Calvin, BSEE senior preparedness analyst in the Gulf of Mexico Region, said: “Though it might seem counterintuitive, the success of a drill is not necessarily determined by whether shortfalls were exhibited during the exercise or not. The success is in the team’s capacity to learn from any mistakes which may have occurred. After all, the best time to become aware of areas for improvement is before an actual emergency response situation arises.”

Representatives from BSEE and the Louisiana Oil Spill Coordinator’s Office participated in the coordination and execution of the exercise, which took about six weeks to plan.

GIUEs are designed to give BSEE the opportunity to evaluate an operator’s access to necessary resources and test the effectiveness, performance, and viability of oil spill response plans, oil spill equipment, and spill management recovery vessels.

This was BSEE’s third deployment exercise in the Gulf of Mexico conducted this fiscal year.
