New Oil Spill Response Calculators

The Bureau of Safety and Environmental Enforcement (BSEE) announced the release of four new oil spill response calculators today as part of an ongoing effort to improve future clean-up efforts. According to John Caplis, an oil spill response coordinator for the bureau, the use of the calculators is viewed by BSEE as a “best practice” and their use will be strongly encouraged when operators prepare oil spill response plans for offshore facilities.

The four calculators are:

Estimated Recovery System Potential (ERSP) Calculator – Provides a systems-based approach that is a significant improvement over the existing Effective Daily Recovery Capacity (EDRC) planning standard.  While EDRC focused only on the capacity of the skimming device and removal pump, ERSP addresses the entire system’s ability to encounter, collect, contain, remove, store and offload recovered oil and water.  The improvements address concerns expressed by the Deepwater Horizon Commission that the EDRC standard does not accurately estimate the removal capacity of mechanical recovery equipment.

Recovery System Evaluation Tool (ReSET) – Allows plan holders and Oil Spill Removal Organizations to explore changes to their mechanical recovery systems and consider options to improve the system’s oil removal potential.  ReSET allows users to vary individual components in the Estimated Recovery System Potential Calculator and determine how they can best invest in mechanical recovery equipment.

Estimated Dispersant System Potential (EDSP) Calculator – Provides a technology update to the Dispersant Mission Planner 2 used by the U.S. Coast Guard to estimate the ability of different aircraft to spray dispersants and treat oil on the water’s surface. The EDSP Calculator features an improved user interface, added spray application platforms, and a more visual and intuitive set of graphical outputs.

The Estimated Burn System Potential (EBSP) Calculator – This new oil spill countermeasure planning tool provides a way to estimate the potential for a towed fire boom system to encounter, contain, and burn oil.
