SSM Oil Spill Transport: Pt. Wells Oil Spill Model

Pt. Wells Oil Spill Model Comparison: BLOSOM and GNOME

Map showing oil spill location.

As part of a larger project led by the Department of Energy’s National Energy Technology Laboratory (NETL) regarding research on oil spill prediction, prevention, and preparation, PNNL generated hydrodynamic model outputs that were used in a model comparison effort between two oil spill models. The oil spill transport models compared were NOAA’s GNOME (General NOAA Operational Modeling Environment) and NETL’s BLOSOM (Blowout and Spill Occurrence Model). In addition, PNNL created Python scripts that convert outputs from the Salish Sea Model to be directly readable by both oil spill transport models.
PNNL’s Salish Sea Model outputs were used to simulate the historic Pt. Wells oil spill from December 30, 2003, chosen because past attempts to recreate the spill from start to finish were unsuccessful. During a late-night refueling, the Foss tank barge 248-P2 was overfilled and over 4,600 gallons of Bunker Fuel #6 was released into the Puget Sound near Seattle. During a short 30 hour spill, the oil crossed the channel and landed within Port Madison. During this relatively short timeframe, small inaccuracies can have a significant impact on the trajectory, highlighting the importance of validated hydrodynamics in recreating the oil pathway.
