Detection of oil spots

Good evening, I have a problem and I would like to get your help and in case someone has already been through it and overcame the difficulties, in processing the image, to be able to stop the oil stains using the Oil Spill Detection tool, the problem is that the process is stopped at 19 %

The Oil Spill Detection uses a digital elevation model to mask out the land. I think it is related to this error: A process related to digital elevation models is taking forever to finish

Please carefully read and check all options. In case it doesn’t solve the problem, please report which of them you tried.
