Predictions from a subsea release of Oda crude oil related to oil spill response - Evaluation of response options

Abstract

Oil weathering predictions have been performed using the Subsea module integrated in the SINTEF Oil Weathering Model (OWM) of a relevant subsea release from a pipeline rupture (batch release) at the Oda oil field. The OSCAR plume model was run to simulate the buoyancy of the rising plume and initial spreading of the surfaced oil. Response options were evaluated for this oil spill scenario at the Oda field. Due to the predicted film thickness, the surfacing oil from the batch release (total 433 m3) is expecting to emulsify at sea and use of mechanical recovery and dispersant application are therefore considered as relevant oil spill strategies for such a spill.
