In case sealing rings and shaft liners are injured on the oil lubricated stern tube seal, the liners cannot be replaced without withdrawing the tail shaft, while sealing rings can be. There are strong demands to make it possible to replace both the sealing rings and liners without withdrawing the tail shaft, especially, for vessels equipped with controllable pitch propeller. To meet with these demands, the split seal which consists of split liners and split housings has been developed.<BR>The mechanism of the oil oozing out of the joint of split liner on the running test has been studied and the manufacturing technique of split liner to prevent the oil oozing has been developed. The most important problem of split seal has been found to be the displacement at the joint of split liner which affects the oil leakage and wear of sealing rings. These problems were thoroughly investigated through the tests and the allowable displacement at the joint has been determined.
