Abstract
Merchant Vessel Princess Piral was anchored at position 74°50.47' E, 12°45.21'N due to damaged hull, which had 160 T Diesel oil on board, which posed the risk of oil spillage. Initially hypothetical oil drift patterns were generated and sent to Indian Coast Guard (ICG) from the INCOIS during 22 June to 27 June 2022 at regular intervals. As per the simulation, the pollutant moves northward along the shore towards river Netravathi on 23 June 2022. Considering INCOIS oil spill advisories, booms were deployed at the mouth of River Netravathi. For 26 -27 June 2022 also, the pollutant continues to move southward. Synthetic Aperture Radar (SAR) data was acquired on 30.06.2022 from the European Space Agency. Oil slick signatures noticed in the SAR data agreed with the simulation, as the oil drift was found southwards from the spill location. The oil slick co-ordinates from SAR data were fed into the oil spill trajectory model using spray tool. The initial conditions were updated, and oil drift patterns were generated accordingly after seeding process, until 04 July 2022. This paper explains the process involved in generating the trajectories, validating the simulations, and updating the initial conditions. It also emphasizes the need for field information and satellite datasets in converting the hypothetical advisories to a real one, as there are high chances of oil leak after shipwrecks.
