Recently, many studies have been conducted for stern tube seals, though which their performance has been considerably improved.<BR>In this course, number of troubles on stern tube seals caused by the damage of sealing rings or liners have been reduced compared with those by other causes such as the catch of fishing nets and ropes. The aft stern tube seal is usually covered with a propeller rope guard to protect the seals from fishing nets and ropes. The fishing nets and ropes caught by the propeller blade, however, would easily coil around the liner through the gap between the propeller boss and rope guard.<BR>Some improved rope guards were designed to prevent the coiling of fishing nets and ropes around the liner and then the performances were examined. It was found from the examination that a new idea “Net Protector” is very effective to protect the stern tube seals from fishing nets and ropes.
