Summary:To provide a ship capable of holding at least a part of a deck in a target height position without using a friction force sensor.SOLUTION: A ship comprises a hull, a hydraulic cylinder, a deck connected via the hull and the hydraulic cylinder, a hydraulic pump constituting a closed circuit through connection to the hydraulic cylinder, a supporting capacity calculation unit to calculate the supporting capacity to support the deck using the hydraulic cylinder, and a flow control unit to adjust a flow rate of the hydraulic oil flowing in the circuit by controlling the hydraulic pump based on the supporting capacity. The flow control unit controls the flow rate so that the supporting capacity of the hydraulic cylinder approaches the preset standard weight as weight supported by the hydraulic cylinder.SELECTED DRAWING: Figure 9 【課題】摩擦力センサを用いることなく、デッキの少なくとも一部を目標高さ位置に保つことができる船舶を提供する。【解決手段】船舶は、ハルと、油圧シリンダと、ハルと油圧シリンダを介して連結されるデッキと、油圧シリンダと接続されて閉回路を構成する油圧ポンプと、油圧シリンダがデッキを支持する支持力を算出する支持力算出部と、支持力に基づいて油圧ポンプを制御して、回路を流れる作動油の流量を調整する流量制御部と、を備える。流量制御部は、油圧シリンダの支持力が、油圧シリンダが支持する重量として予め設定された基準重量に近づくように、流量を調整する。【選択図】図９
