Oil pollution risks on coastlines in the Eastern China Seas.

As maritime transportation experiences continuous development, the escalating potential risk of oil spills necessitates thorough and detailed risk assessments. Realizing the inherent contingency and unpredictability of oil spill incidents, this study employs a 3D oil spill model combining with long-term hydro-meteorological data to evaluate the oil pollution risk (OPR) along the coastlines of the Eastern China Seas. Through simulations spanning four seasons over 21 years (2001-2021), diverse scenarios are captured.

Mesoscale evaluation of oil submerging and floating processes during marine oil spill response: Effects of dispersant on submerging stability and the associated mechanism.

The migration of oil spills in marine environment is still not clear, especially the key processes of submerging and floating, which is an important concern for effective disposal of oil spills. In mesoscale wave tank (32 m × 0.8 m × 2 m), this study has evaluated the characteristics of oil submergence based on oil concentration and oil droplet size.

Impact of ocean waves on transport of underwater spilled oil in the Bohai Sea.

To investigate the impact of ocean waves on transport of underwater spilled oil, a wave action module is developed and embedded into an underwater oil spill model. Combined with a validated hydrodynamic background data, the model is applied to a short-term numerical simulation of the 2011 Penglai 19-3 oil spill event in the Bohai Sea. Numerical result shows that the model result is rationally consistent with the field observation.
