Abstract: The invention relates to a machinery arrangement for a marine vessel (1), which machinery arrangement (2) comprises a combustion unit (3), an exhaust gas duct assembly (4), which includes a first branch pipe (41) and a second branch pipe (42) and is connected to the combustion unit for receiving an exhaust gas flow and for leading the exhaust gas flow to the atmosphere, and an exhaust gas cleaning system (5) arranged in a flow direction of exhaust gas. In order to achieve an improved cleaning of the exhaust gas, a fan unit (6) and a first valve means (7) is provided in flow connection with the first branch pipe (41), which is connect to the exhaust gas cleaning system (5).

Abstract: The invention relates to a machinery arrangement, which comprises a combus-tion unit (3) arranged in an engine room (11), and an exhaust gas duct assem-bly (4) connected to the combustion unit (3) for receiving an exhaust gas flow and for leading the exhaust gas flow to the atmosphere through an exhaust gas cleaning system (5) provided with an exhaust gas pipe (52). In order to condi-tion the exhaust plume, the exhaust gas pipe (52) is arranged in an enclosure (114), whereby the enclosure (114) is arranged in flow connection with the en-gine room (11) in order to provide heat for the exhaust gas pipe (52) by means of a heated air flow from the engine room.

Abstract: The invention relates to a machinery arrangement of a marine vessel, which machinery arrangement comprises an internal combustion engine (1), a heat recovery device (2) for recovering waste heat from the exhaust gas of the internal combustion engine (1), a scrubber unit (3) for scrubbing the exhaust gas, and a separate heating system (4) for producing heat. The machinery arrangement further includes a reheating device (30) in flow connection with the heat recovery device (2) for reheating the exhaust gas from the scrubber unit (3) or for dumping excess heat.

Abstract: Apparatus for sealing a cylindrical roll with respect to a trough in which the roll is disposed is disclosed, the apparatus comprising an end seal applied to the end surface of the cylindrical roll, a longitudinally extending seal applied to the barrel-shaped outer surface of the cylindrical roll, and a spring for dynamically urging the end seal against the end surface of the cylindrical roll and against the longitudinally extending seal.

Abstract: The invention relates to a method for preventing leaks in a propeller shaft bearing arrangement including a plain bearing (2), which is lubricated with oil or water and which supports the propeller shaft (1) extending through an opening in the body (4) of a hull, and packing members (6,7) for keeping the lubricant in the lubrication space and for preventing water from entering the bearing arrangement. According to the invention, the pressure vibrations occuring in the lubricant are equalized arranging, in the lubrication space, a medium possessing a high compressibility, which medium by means of changes in volume receives and equalizes said pressure vibrations.
