A system includes a first jacket (202) that contains water and a first tank (206) storing a first fluid under pressure. A second jacket (204) contains water and a second tank (208) storing a second fluid under pressure. An actuator cylinder (214) defines a space that receives the fluids from the first and second tanks. The actuator cylinder includes an actuator piston (234) that divides the space into a first volume for the first fluid and a second volume for the second fluid. A hydraulic cylinder (216) includes a hydraulic piston (236) configured to move and change an amount of hydraulic fluid (218) in the hydraulic cylinder, where the hydraulic piston is fixedly coupled to the actuator piston. A buoyancy plug (108) changes a position in connection with the amount of the hydraulic fluid in the hydraulic cylinder, where the position of the buoyancy plug affects a buoyancy of a vehicle (100).
