Abstract
An oceangoing vessel exhaust pipe coupling used to temporarily couple to an oceangoing vessel exhaust pipe. Installation and removal of the coupling only requires a simple mechanism with three translational degrees of freedom and one rotational degree of freedom, thereby enabling remote coupling. The coupling adapts to a wide array of exhaust pipe shapes and sizes. This is accomplished by a unique shape that allows stable and balanced resting position on top of an exhaust pipe as well as a two-chamber configuration, wherein the two chambers are separated by a permeable partition. Furthermore, the unique shapes of the chambers deflect the exhaust gas stream towards the outlet of the coupling, regardless of exhaust pipe style, thereby increasing capture efficiency and extending the life of an attached fabric flexible hose.
