PROBLEM TO BE SOLVED: To provide a vessel provided with a ballast water treatment device capable of suppressing or preventing the generation of the inhibition factors of ballast water treatment using a water solution obtained by dissolving a chlorine-based chemical into water as a bactericidal agent.SOLUTION: Provided is a vessel VSL comprising: a ballast pump Pm including the first operation mode circulating ballast water Wo taken from the outside of the vessel toward a ballast tank T so as to be stored into the ballast tank and the second operation mode circulating the ballast water taken from the outside of the vessel through the inside of the vessel without passing through the ballast tank; and a ballast water treatment device including: a bactericide injection port Is of injecting a chlorine-based bactericide As to the ballast water circulating toward the ballast tank upon the first operation mode; and a residue injection port Id of injecting at least a part of the residue Re of the chlorine-based bactericide remaining without being injected into the ballast water upon the second operation mode and upon the first operation mode into the ballast water circulating inside the vessel.SELECTED DRAWING: Figure 16

    【課題】塩素系薬剤を水に溶解して得た水溶液を殺菌剤として使用するバラスト水処理の阻害要因の発生を抑制又は防止できるバラスト水処理装置を具備する船舶を提供することである。【解決手段】船舶VSLが:船外から取水したバラスト水WoをバラストタンクTに向かって流通させバラストタンクに収容する第1の運転モードと、船外から取水したバラスト水をバラストタンクを経由することなく船内を流通させる第2の運転モードを備えたバラストポンプPmと;第1の運転モードのときバラストタンクに向かって流通するバラスト水に塩素系殺菌剤Asを注入する殺菌剤注入口Isと、第2の運転モードのとき第1の運転モードのときにバラスト水に注入されず残った塩素系殺菌剤の残留物Reの少なくとも一部を船内に流通するバラスト水に注入する残留物注入口Idとを備えるバラスト水処理装置と、を備える。【選択図】 図16
