1. An exhaust pipe coupling configured to temporarily couple to an exhaust pipe of an oceangoing vessel, the exhaust pipe coupling comprising:
a container with an inlet chamber and an outlet chamber, with said inlet and outlet chambers separated by a permeable partition configured to allow exhaust gas flow from the inlet chamber into the outlet chamber;
wherein said inlet chamber is wedge-shaped, oriented with a wide aspect extending in a downward direction, with an inlet opening at a bottom of the container sufficiently large to fit over a top aspect of the exhaust pipe and configured to receive the top aspect of the exhaust pipe within the inlet chamber through the inlet opening to temporarily couple to the exhaust pipe;
wherein said permeable partition constrains the exhaust pipe within said inlet chamber while also providing a path for exhaust gas flow emitted from the exhaust pipe to pass from said inlet chamber to said outlet chamber;
wherein said outlet chamber is wedge-shaped, with a wide aspect extending upwardly, with an outlet at a top of the outlet chamber for providing an exit for said exhaust gas flow.
