Abstract:
(EN) Disclosed is a ship engine operating method. The ship engine operating method comprises: the first step for varying the gas ratio from 0 to 100% for a first engine at the current load, and determining the gas consumption for each gas ratio; the second step for varying the gas ratio from 0 to 100% for the first engine at the current load, and determining fuel oil consumption for each gas ratio; the third step for varying the gas ratio from 0 to 100% for the first engine at the current load, and calculating the amount of combustible gas in the second engine for each gas ratio; the fourth step for determining the gas ratio of the second engine for each amount of combustible gas in the second engine calculated in the third step; the fifth step for calculating the fuel oil consumption at the current load in the second engine for each gas ratio thereof determined in the fourth step; the sixth step for calculating the total fuel oil consumption by adding the fuel oil consumption of the first engine calculated in the second step and the fuel oil consumption of the second engine calculated in the fifth step; and the seventh step for transmitting commands to the first engine and second engine so that same operate at the gas ratios of the first and second engines as in the case of the lowest total fuel oil consumption as calculated in the sixth step. The first engine and second engine are operated in a fuel sharing mode.
(FR) La présente invention concerne un procédé de fonctionnement d'un moteur de navire. Le procédé de fonctionnement de moteur de navire comprend : la première étape consistant à faire varier le rapport de gaz de 0 à 100 % pour un premier moteur à la charge actuelle, et à déterminer la consommation de gaz pour chaque rapport de gaz ; la deuxième étape consistant à faire varier le rapport de gaz de 0 à 100 % pour le premier moteur à la charge actuelle, et à déterminer la consommation de fioul pour chaque rapport de gaz ; la troisième étape consistant à faire varier le rapport de gaz de 0 à 100 % pour le premier moteur à la charge actuelle, et à calculer la quantité de gaz combustible dans le second moteur pour chaque rapport de gaz ; la quatrième étape consistant à déterminer le rapport de gaz du second moteur pour chaque quantité de gaz combustible dans le second moteur calculée à la troisième étape ; la cinquième étape consistant à calculer la consommation de fioul à la charge actuelle dans le second moteur pour chaque rapport de gaz de ce dernier déterminé à la quatrième étape ; la sixième étape consistant à calculer la consommation totale de fioul en additionnant la consommation de fioul du premier moteur calculée à la deuxième étape et la consommation de fioul du second moteur calculée à la cinquième étape ; et la septième étape consistant à transmettre des commandes au premier moteur et au second moteur de telle sorte que ces derniers fonctionnent aux rapports de gaz des premier et second moteurs comme dans le cas de la consommation totale de fioul la plus faible telle que calculée à la sixième étape. Le premier moteur et le second moteur sont amenés à fonctionner dans un mode de partage de carburant.
