PROBLEM TO BE SOLVED: To provide a sea water cooling system for vessel capable of cooling facilities related to EGR without increasing pump capacity in a vessel provided with EGR.SOLUTION: A main cooled seawater pump 14A for supplying seawater to a main machine, a cooling cooler related to main machine 18 and a cooled fresh water cooler for auxiliary machine 20 is provided. An auxiliary cooled seawater pump 16 is provided for supplying the seawater to the cooled fresh water cooler for auxiliary machine 20 or a main machine EGR central cooler 24. An operating mode is capable of being switched between: a first operating mode for driving the main cooled seawater pump 14A as well as stopping the auxiliary cooled seawater pump 16; a second operating mode for driving the main cooled seawater pump 14A as well as supplying the seawater to the main machine EGR central cooler 24 by driving the auxiliary cooled seawater pump 16; and a third operating mode for supplying the seawater to the cooled fresh water cooler for auxiliary machine 20 and the main machine EGR central cooler 24 by stopping the main cooled seawater pump 14A as well as driving the auxiliary cooled seawater pump 16.SELECTED DRAWING: Figure 1
【課題】EGRを備えた船舶において、ポンプ容量を大きくすることなくEGRに関連する設備の冷却が行える海水冷却システムを提供する。【解決手段】主機及び主機関連冷却クーラ18、補機用冷却清水クーラ20に海水を供給する主冷却海水ポンプ14Aを設ける。補機用冷却清水クーラ20または主機EGRセントラルクーラ24に海水を供給する補助冷却海水ポンプ16を設ける。主冷却海水ポンプ14Aを駆動するとともに補助冷却海水ポンプ16を停止する第1運転モードと、主冷却海水ポンプ14Aを駆動するとともに、補助冷却海水ポンプ16を駆動して主機EGRセントラルクーラ24に海水を供給する第2運転モードと、主冷却海水ポンプ14Aを停止するとともに、補助冷却海水ポンプ16を駆動して補機用冷却清水クーラ20および主機EGRセントラルクーラ24に海水を供給する第3運転モードとの間で運転モードを切り換え可能とする。【選択図】図1
