Publication number: 20240116619Abstract: A digital twin computation section collects a speed of an own ship, a position of the own ship, and a heading of the own ship in real time, and reproduces an actual hull motion of the own ship realized at a current steering angle on a navigational electronic marine chart. A simulation computation section displays, on the navigational electronic marine chart, an assumed hull motion of the own ship determined by calculation that assumes that a force acting on the hull is a driving force at the current steering angle. A resultant force of external forces computation section calculates an acting direction and a magnitude of a resultant force of external forces acting on the hull based on a ship speed difference, ship position difference, and heading difference between the actual hull motion and the assumed hull motion.Type: ApplicationFiled: August 9, 2022Publication date: April 11, 2024Applicant: JAPAN HAMWORTHY & CO., LTD.Inventors: Kazushi TOMITA, Hirotaka YAMAMOTO

Patent number: 11915595Abstract: In collision-avoidance maneuvering in congested waters, an own ship is decelerated by astern power. The own ship is continuously navigated on a current target course with a propulsion propeller always rotated forward at the stern of the own ship. The astern power is generated as the propulsion of a propeller slipstream with rudder angles formed at a pair of right and left high-lift rudders disposed behind the propulsion propeller. In the decelerating maneuvering, the rudder angles formed at the high-lift rudders are controlled within a range from a rudder angle for applying a maximum propeller slipstream as the astern power to a rudder angle for eliminating the ahead power of the propeller slipstream, and the deceleration of the own ship is controlled by changing the astern power according to the rudder angles.Type: GrantFiled: November 21, 2019Date of Patent: February 27, 2024Assignee: JAPAN HAMWORTHY & CO., LTD.Inventors: Kazushi Tomita, Hirotaka Yamamoto

Patent number: 8396644Abstract: A control device for an internal combustion engine employing PCCI combustion, capable of realizing high-stability operation of the engine throughout a large operation area, is provided. The engine control device comprises a fuel supply system which supplies light oil or mixed fuel containing light oil to the engine, a gas supply system which supplies hydrogen to the engine, and a required premixed gas calculating unit which previously stores and uses multiple combustion waveforms (changing depending on hydrogen addition concentration) as data. The required premixed gas calculating unit selects one of the combustion waveforms so as to achieve high thermal efficiency depending on the status of the engine and determines the hydrogen addition concentration (addition concentration of the hydrogen to be supplied to the engine) corresponding to the selected combustion waveform, by which the generation of PM and NOx can be reduced while also improving the thermal efficiency of the engine.Type: GrantFiled: April 21, 2010Date of Patent: March 12, 2013Assignee: Honda Motor Co., Ltd.Inventors: Hajime Kabashima, Yasuhiro Urata, Kazushi Yamamoto
