Simulation of Bohai sea tidal during Penglai 19-3 oil spill accident based on Mike21 model

Abstract

The calculation and prediction the tide are now available for a variety purposes. In order to improve the accuracy of forecasting and prevention of oil spill pollution at sea, it is very important to forecast the direction and velocity of the current in the incident area. In this article, the author used Mike21 model, an application included in the Mike Zero software, to calculate the tide in the Bohai Sea and a part of the Yellow Sea. Through the construction of the triangle mesh, topographical data, water level data of the simulation’s time, we has already simulated accurately result of the tide information, especially the tidal data at Penglai 19-3 oil-rig position. This result was compared with the actual measured data and showed a high degree of coincidence, it completely can be used in the oil spill simulation model in the Bohai Sea.
