  • Publication number: 20200280192
    Abstract: An electric power plant includes at least one electric machine operable as a generator when rotated by a piston engine. The electric power plant includes a control system for interrupting the fuel supply of the piston engine in response to a need to interrupt power supply from the electric machine, and for reactivating the fuel supply in response to a need to reactivate the power supply. The control system is configured to keep the electric machine connected to voltage when the fuel supply of the piston engine is interrupted so as to operate the electric machine as an electric motor for rotating the piston engine. As the electric machine and the piston engine are rotating when the power supply from the electric machine is interrupted, the reactivation of the power supply can be fast.

  • Patent number: 10759510
    Abstract: The present disclosure discusses a method of and an arrangement for the lubrication of a controllable pitch propeller of a marine vessel. The lubrication is based on continuous lubricant circulation from the hydraulic powerpack to the hub and back to the oil tank, when the marine vessel is sailing ahead with propeller blades locked in a desired position. The lubrication is performed by maintaining, at least when the propeller blades are locked in a desired position, a pressure difference between the astern oil chamber and the lubricant chamber for circulating lubricant from the astern oil chamber via the lubricant chamber to the oil tank.
