On the oil lubricated stern tube seals, the lubricating oil in stern tube leaks into sea when sealing rings are damaged by accident and the oil leakage causes the sea water pollution. It is necessary to remove the leaking oil to prevent the sea water pollution and experimental studies have been carried out to remove the leaking oil.<BR>The flow of leaking oil at the outside of stern tube was observed on a test stand to find out the effective removal method. Then various experiments were carried out to remove the leaking oil from the outside of stern tube seal and also from the inside of stern tube seal respectively.<BR>It was found from the experiments that the leaking oil could be well removed from the oil chamber between No. 2 and No. 3 sealing rings on the aft seal. Then an oil removal equipment was designed to remove the leaking oil efficiently and it was confirmed through the test that the equipment had sufficient performance.
