A sectional barge assembly and a hydraulic thruster apparatus for maneuvering the sectional barge assembly. The hydraulic thruster apparatus includes a hydraulic power unit and a thruster unit to move the barge assembly. A hydraulic connection panel is mounted on the thruster unit and includes a plurality of hydraulic connectors which allow a plurality of hydraulic lines to be removably connectable thereto, respectively. By this arrangement, the hydraulic pump provides pressurized hydraulic fluid through the hydraulic lines thereto the hydraulic motor and other components of the thruster unit. Additionally, the thruster unit includes at least one hydraulic cylinder for controlling vertical rectilinear sliding of a thruster unit mast between a top position and a bottom position. The thruster unit also includes a rotating mechanism for rotating the mast and a propeller assembly of the thruster unit about a longitudinal axis of the mast.
