Identification of leakage tendency and optimum operating parameters on a newly fitted stern tube seal

Stern tube seal is widely used in marine transportation to provide improved sealing for watertight integrity at higher shaft revolution. If the operating parameters exceed the optimum operating cooling water pressure with reference to variable initial operating and boundary conditions, deformation w...
