    摘要： A keel cooler assembly comprising a coolant tube including a plurality of turbulence enhancers for improving the heat transfer of the coolant without substantially increasing pressure drop of the coolant. In one embodiment, the turbulence enhancers provide a means for generating turbulent wakes in the coolant for disrupting laminar boundary layers for improving heat transfer. In another embodiment, the turbulence enhancers provide a means for generating and propagating turbulent vortexes in the coolant to enhance mixing of the bulk coolant for improving heat transfer. In other embodiments, turbulators, including inserts or impediments, are provided having various configurations and being arranged in predetermined patterns for enhancing turbulence of the coolant for improving keel cooler heat transfer efficiency without substantially increasing pressure drop.

    摘要： The invention relates to a ship's propulsion unit comprising a closed liquid cooling system (9) having an inner space (10) containing liquid. The inner space (10) is partly limited by a cylindrical outer surface (8) of a cylindrical section (7) of a motor housing section (6) of the propulsion unit for exchanging thermal energy between an electric motor (3) arranged in the cylindrical section (7) of the motor housing section (6) and liquid in the inner space (10). The inner space (10) of the closed liquid cooling system (9) is partly limited by the shell structure (1) of the propulsion unit so that liquid in the inner space (10) is in direct contact with the shell structure (1) of the propulsion unit for exchanging thermal energy between liquid in the inner space (10) and water surrounding the propulsion unit via the shell structure (1) of the propulsion unit.

    摘要： Provided is a system for monitoring temperature and pressure of an enclosed derrick structure, which senses abnormal internal temperature and pressure of the enclosed derrick structure by monitoring the temperature and pressure of the enclosed derrick structure, thereby effectively coping with dangers. A system for monitoring temperature and pressure of an enclosed derrick structure communicating with a moonpool includes: one or more temperature sensors installed in the inside of the enclosed derrick to monitor an internal temperature of the enclosed derrick; one or more pressure sensors installed in the inside of the moonpool to monitor an internal pressure difference of the moonpool; and one or more damping units installed in a side of the enclosed derrick to supply air to the inside of the enclosed derrick or exhaust air to the outside of the enclosed derrick in order to cope with an abnormal internal temperature of the enclosed derrick and an abnormal internal pressure variation of the moonpool. Accordingly, when the abnormal internal temperature of the enclosed derrick and the abnormal internal pressure of the moonpool are sensed by the monitoring of the temperature sensors and the pressure sensors, the damping units are selectively controlled according to the sensing results.

    摘要： The invention relates to a ship propulsion system that comprises at least one marine propeller (7), at least one electric motor (6) which drives the at least one marine propeller (7), and an inverter-fed power supply system which supplies the at least one electric motor (6) with electric power. Said power supply system comprises at least one drive machine and at least one generator driven thereby. The at least one electric motor and the at least one generator are configured as three-phase synchronous machines. In order to reduce losses per kW installed power and thus to allow for a stronger energizing field in the stator winding, the at least one electric motor configured as a three-phase synchronous machine and/or the at least one generator configured as a three-phase synchronous machine of the power supply system is/are provided with an air-gap three-phase winding (10) devoid of iron grooves as the power supply system. The bundle conductors of said winding are made from insulated thin copper wires that are disposed in an annular gap (11) between a rotor (8) and a laminated iron yoke (12) that is reinforced by a plastic structure (14) and/or embedded in or impregnated with resin and to which a pertaining cooling device (13) is connected by which the heat produced in the cooling device is dissipated.
