Abstract
(EN)
This liquefied gas carrying vessel has a cargo tank for storing a liquefied gas and has a spray device for carrying out spray work for spraying the liquefied gas into the cargo tank, and uses gas generated by vaporizing the liquefied gas as propulsion fuel, wherein, when calculating, from the vapor quality in the cargo tank, a spray vaporization rate indicating the ratio of the flowrate of gas vaporized in the cargo tank with respect to a spray flowrate of the liquefied gas, a coefficient by which the vapor quality is multiplied is calculated in advance on the basis of actual measurement data in the liquefied gas carrying vessel, and the spray vaporization rate at an arbitrarily defined date during sailing is predicted on the basis of a value obtained by multiplying the vapor quality by the coefficient at the arbitrarily defined date.

Le récipient de transport de gaz liquéfié selon l'invention comprend une citerne à cargaison servant à stocker un gaz liquéfié et comprend un dispositif de pulvérisation servant à effectuer un travail de pulvérisation pour pulvériser le gaz liquéfié dans la citerne à cargaison, et utilise un gaz généré par la vaporisation du gaz liquéfié comme combustible de propulsion. Lors du calcul, à partir du titre en vapeur dans la citerne à cargaison, d'un taux de vaporisation lors de la pulvérisation indiquant le rapport entre le débit du gaz vaporisé dans la citerne à cargaison et un débit de pulvérisation du gaz liquéfié, un coefficient par lequel le titre en vapeur est multiplié est calculé à l'avance sur la base de données de mesure réelles dans le récipient de transport de gaz liquéfié, et le taux de vaporisation lors de la pulvérisation à une date définie arbitrairement pendant la navigation est prédit sur la base d'une valeur obtenue par multiplication du titre en vapeur par le coefficient à la date définie arbitrairement.

液化ガスを貯留するカーゴタンク、及び、液化ガスをカーゴタンク内に吹き付けるスプレー作業を行うスプレー装置を有し、液化ガスが気化して発生するガスを推進用の燃料とする液化ガス運搬船において、液化ガスのスプレー流量のうちカーゴタンク内で気化するガスの流量の割合を表すスプレー気化率をカーゴタンク内の蒸気クォリティから算出する際に蒸気クォリティに乗算する係数を液化ガス運搬船での実測データに基づいて予め求めておき、航海中の任意の日時のスプレー気化率を、任意の日時における蒸気クォリティに係数を乗じた値で予測する。
