Immersible length - Kashincho

…For this reason, the ratio of flooding to the volume of the compartment (flooding rate) is calculated for each type of compartment (engine room, living space, cargo hold, etc.), and the attitude of the ship in that flooded state is calculated to determine the length of the compartment at which the waterline reaches the limit line. This is called the floodable length, and is shown as a curve that changes along the length of the ship. This floodable length multiplied by the compartment coefficient is called the allowable length, and it is acceptable for the length of the compartment measured at any location to be less than this allowable length. …

*Some of the terminology that refers to "floodable length" is listed below.

…そのため，区画の種類(機関室，居室，貨物倉など)ごとに区画容積に対する浸水量の比(浸水率)を求め，その浸水状態の船の姿勢を計算して喫水線が限界線に達するような区画の長さを求める。これを可浸長と呼び，船の長さに沿って変化する曲線で示される。この可浸長にさらに区画係数を掛けたものを可許長と呼び，どの場所で測った区画の長さもこの可許長以下であればよいとする。…
