1,063,410. Stabilizing ships. JOHN J. Mc- MULLEN ASSOCIATES Inc. Nov. 12, 1965 [Sept. 23, 1965], No. 48212/65. Heading B7M. A stabilization and heeling tank system (10), Fig. 1 (not shown), in a ship includes a rectangular tank (12) mounted transversely across the hull, a centre line bulkhead (14) dividing the tank (12) into two substantially equal volumed compartments and two spaced openings (70) in the bulkhead which extend through a major distance of the height of tank (12). The tank is filled to a predetermined level (90) with sea water, fuel or bunker oil and liquid transfer between the compartments is controlled by sliding doors (22) which are moved by cylinder-piston units (30). Pump means (52) communicating with the two compartments can also selectively move liquid from either one of the compartments to the other. One or more additional longitudinal bulkheads (42) having spaced cuts (44) and semicircular cuts (46) are provided in each compartment of tank (12). Sliding doors (22) may be replaced by doors rotatable about a vertical axis or about a horizontal axis. |
