SeaThigor Shaft Seals - Default
The faces that we use for this seal are silicon carbide. If the silicon carbide faces ever get damaged, the safe return to port seal means that the shaft can still turn with the seal in place. It works by activating an inflatable seal and the vessel can proceed to a repair facility on its own power, at reduced speeds.
