Ship
A ship ( 1 ) includes a hull ( 2 ) having side shells ( 3 A, 3 B) formed at both sides in athwart ship direction, a pair of watertight compartments ( 6 A, 6 B) installed along the side shells ( 3 A, 3 B) of both sides in the athwart ship direction in the hull ( 2 ) and portions of which are divided and formed by the side shells ( 3 A, 3 B), a connection section ( 7 ) configured to bring the pair of watertight compartments ( 6 A, 6 B) in connection with each other, an opening/closing valve ( 8 ) installed at the connection section ( 7 ), and a control device ( 9 ) configured to control the opening and closing of the opening/closing valve ( 8 ), wherein the control device ( 9 ) switches the opening/closing valve ( 8 ) in an open state into a closed state when a predetermined condition is satisfied after receiving a signal indicating damage to the side shell ( 3 A) has occurred.
1. A ship comprising:
a hull having side shells formed at both sides in an athwart ship direction;
a first watertight compartment formed at one side in the athwart ship direction in the hull and a portion of which is divided and formed by the side shell of the one side;
a second watertight compartment formed at the other side in the athwart ship direction in the hull and a portion of which is divided and formed by the side shell of the other side;
a connection section configured to bring the first watertight compartment and the second watertight compartment in connection with each other;
an opening/closing valve configured to open and close the connection section; and
a control device configured to control the opening and closing of the opening/closing valve,
wherein the control device switches the opening/closing valve in an open state into a closed state when a predetermined condition is satisfied upon receiving a signal indicating an occurrence of damage to the side shell, and
switches the opening/closing valve into the closed state when at least one of a condition that an elapsed time from reception of the signal indicating the occurrence of damage to the side shell reaches a predetermined setting time and a condition that the hull has a predetermined roll amplitude is satisfied as the predetermined condition.
2. A ship comprising:
a hull having side shells formed at both sides in an athwart ship direction;
a first watertight compartment formed at one side in the athwart ship direction in the hull and a portion of which is divided and formed by the side shell of the one side;
a second watertight compartment formed at the other side in the athwart ship direction in the hull and a portion of which is divided and formed by the side shell of the other side;
a connection section configured to bring the first watertight compartment and the second watertight compartment in connection with each other;
an opening/closing valve configured to open and close the connection section; and
a control device configured to control the opening and closing of the opening/closing valve,
wherein the control device switches the opening/closing valve in an open state into a closed state when a predetermined condition is satisfied upon receiving a signal indicating an occurrence of damage to the side shell, and
the control device switches the opening/closing valve into the closed state when a condition that the hull has a predetermined amplitude is satisfied as the predetermined condition.
3. The ship according to claim 1 , wherein the control device switches the opening/closing valve into the open state when the signal indicating the occurrence of damage to the side shell is received, and switches the opening/closing valve in the open state into the closed state when the predetermined condition is satisfied, where the opening/closing valve is normally in the closed state.
