摘要： Disclosed herein is a micro-leak detection system of a reliquefaction system for ships. The micro-leak detection system includes: a reliquefaction system reliquefying boil-off gas generated from a liquefied gas stored in a storage tank in a ship by recovering cold heat from the boil-off gas in a heat exchanger, compressing the boil-off gas, and cooling the compressed boil-gas in the heat exchanger through heat exchange with refrigerant circulated along a refrigerant circulation line; a heater heating the boil-off gas to be supplied from the storage tank to the heat exchanger through heat exchange with an antifreeze liquid; and a micro-leak detection device connected to a drain port through which a remaining liquid is drained from the heater and detecting small leaks in the heater.

摘要： A safety system according to the present invention comprises an on-ship system which is provided on a ship and a land system which is provided on land. The on-ship system and the land system each obtain, from a safety detection device and a safety maintenance device which are provided on a ship, data which has been detected by the safety detection device and a signal which indicates a state of the safety maintenance device, and, on the basis of the obtained data and signal, transmit to the safety maintenance device a control signal for controlling the safety maintenance device.

摘要： An optimum engine configuration is determined, based on a predicted required power, for a seafaring vessel having a plurality of thrust engines. The predicted required power is determined by inputting environmental data, and voyage data to a required power model. At least some of the environmental data is received from a plurality of sensors. The optimum engine configuration is selected from a plurality of candidate engine configurations. Each candidate engine configuration includes a specified number of thrust engines running and a specified power output level of each thrust engine. The optimum engine configuration is selected based on a candidate total predicted fuel consumption of each candidate engine configuration. The candidate total predicted fuel consumption amount is determined as a sum of the engine-specific predicted fuel consumptions determined for each running thrust engine of that candidate engine configuration.

摘要： The purpose of the present disclosure is to suppress an error which occurs in movement, such as in anchoring a ship. A ship navigation assistance device includes a measurement module and a characteristic information updating module. The measurement module acquires measurement information on an object using a ranging result of an area including the object that is an anchorage target of a ship. The characteristic information updating module updates characteristic information on the object using initial characteristic information on the object or characteristic information before updating on the object, and the measurement information.

摘要： Example systems and methods are provided herein for stabilizing a watercraft during a turn of the watercraft. Such systems include a navigation assembly and a stabilization mechanism configured to apply forces to maintain the watercraft within a relative orientation with a body of water. The systems also include a memory and a processor, and the processor is configured to receive data from the navigation assembly to determine when a turn is being made or will be made, determine and apply an adjustment to the stabilization mechanism, and cause the adjustment to be applied to the stabilization mechanism.

摘要： A marine contra-rotating propeller apparatus (100) comprises: an outer shaft (12) to which the front propeller (1) is attached, an inner shaft (14) to which a rear propeller (2) is attached, a contra-rotating thrust bearing (40) configured to transmit a thrust force acting on the front propeller to the inner shaft, and a contra-rotating gear device (20) configured to rotate the outer shaft and the inner shaft in directions opposite to each other. The contra-rotating gear device (20) has an inner shaft thrust bearing (50) configured to support a thrust force of the inner shaft and hold an axial position of the inner shaft. The thrust clearance measuring device (60) has: an inner shaft position sensor (62) configured to measure a forward-traveling-time inner-shaft position F1 and a backward-traveling-time inner-shaft position R1 in an axial direction during an operation of a marine vessel; and a thrust clearance calculation device (66) configured to calculate a first thrust clearance(C1) of the inner shaft thrust bearing.

摘要： It is intended to provide a marine propulsion device information transmitting and receiving system, whereby data related to an engine of a watercraft can be inhibited from being falsified. The marine propulsion device information transmitting and receiving system includes a watercraft and a server. The watercraft includes a propulsion device that includes an engine and a controller that controls the engine and is connected to a communication device. The controller encrypts an operating time of the engine and data related to the engine with an encryption key associated with information unique to the engine. The watercraft further includes a communication device that transmits the information unique to the engine, the encrypted operating time of the engine, and the encrypted data related to the engine to the server. The server receives the information unique to the engine, the encrypted operating time of the engine, and the encrypted data related to the engine, decrypts the encrypted operating time of the engine and the encrypted data related to the engine with the encryption key associated with the information unique to the engine, and determines whether or not the decrypted data related to the engine are genuine based on the decrypted operating time of the engine.
