  • Engine exhaust bypass system for ocean vessel
    Patent number: 8070542
    Abstract: A primary exhaust bypass for a water-borne vessel having a seat member and a closure member coupled to the seat member, wherein the seat and closure members are configured to seal against exhaust leakage in the closed position and to allow exhaust leakage in the opened condition, and a locking mechanism, wherein the bypass is configured to open when the vessel lists a predetermined amount. A method of bypassing a blocked primary exhaust system may include establishing a bypass exhaust route, providing a normally-closed bypass mechanism at a distal portion of the bypass exhaust route, and changing the orientation of the bypass mechanism with respect to gravity, which may allow the bypass mechanism to open.
