STAXLINK™ is a duct system and method for conveying exhaust gas from an exhaust pipe of an emissions source to a purification unit during an Emissions Reduction as a Service (ERaaS) operation. Example emissions sources include oceangoing vessels and buildings structures. The duct is temporarily installed onto the emissions source without a crane. The duct is supported by the emissions source itself for the duration of the ERaaS operation.

An improvement for inboard motor boats has a rigid exhaust conduit, a miniature rudder, and a rudder control system. The rigid conduit is provided for conduction of combustion gases exhaust outside the hull and has an aft facing outlet. The miniature rudder is pivotably mounted on the rigid conduit relative the aft facing outlet whereby combustion gases exhaust past the rudder. The rudder control system has a user interface inside the boat and has a control mechanism pivoting the rudder in response to inputs to the user interface.

Constraints on arrangement of catalysts are reduced, and early activation and long-term performance maintenance of the catalysts are both achieved. An exhaust pipe includes a first catalyst provided in a first exhaust pipe extending upward on the side of an exhaust manifold, and a second catalyst provided in a second exhaust pipe that extends downward from a bent pipe extending from the first exhaust pipe and that is adjacent to the first exhaust pipe. The second catalyst is disposed at a position offset to a higher location from an up-down middle position of the first exhaust pipe.

Disclosed is a scrubber outlet assembly, the scrubber outlet assembly comprising a pipe having an inner surface, wherein the inner surface has a first portion made from a first electrically conductive material, a second portion made from a second electrically conductive material dissimilar to the first electrically conductive material, and a region comprising at least a part of the first portion and at least a part of the second portion. The scrubber outlet assembly comprises a barrier located inwardly of the inner surface of the pipe. The scrubber outlet assembly defines a flow path through the pipe along which washwater is flowable from a scrubber in use, and the barrier fluidically isolates the region from the flow path.

A multi-circuit system for temporarily connecting to a plurality of exhaust pipes of an oceangoing vessel at berth or at anchor and treating captured exhaust gas. Each circuit includes an exhaust gas processing system, a duct system to reach from the processing system to an exhaust pipe; a duct inlet port for attachment to a connector receiving exhaust gas from an exhaust pipe. A positioning system supports the duct systems and connectors in a ganged relationship and positions the duct systems and connectors in a temporary operational position and in a non-operational position. In another embodiment, blower controller is responsive to a pressure measurement at the duct inlet port or the connector to control a blower speed to set or maintain the pressure to a desired pressure.

The present disclosure relates to an exhaust pipe apparatus. The exhaust pipe apparatus includes a first exhaust pipe provided to directly discharge exhaust gas discharged from a combustion engine to the outside, a second exhaust pipe connected in parallel with the first exhaust pipe and having a branch pipe connected to one side thereof such that the exhaust gas is directly discharged to the outside or discharged through the branch pipe, and a first damper installed in the second exhaust pipe to control a flow of the exhaust gas to be directly discharged to the outside or discharged through the branch pipe.

Disclosed is a power controller for controlling power to be supplied to at least one reefer container on a container vessel. The power controller is configured to obtain a set temperature for at least one reefer container to be transported by the container vessel. The power controller is also configured to obtain data that indicates an amount of energy available to the container vessel and determine, based on the amount of energy available to the container vessel, whether to cool the at least one reefer container below the set temperature.
