<p>A cargo-carrying articulated ship system having icebreaking capabilities is provided herein. It includes of a powered cargo-carrying vessel having an icebreaking hull from, a bow and a stern, and a powered locomotive vessel having an icebreaking hull form, a bow and a stern. In addition, a connection system is provided for connecting the cargo-carrying vessel and the powered locomotive vessel at concave and convex respective bow and stern confugurations to provide an articulated cargo-carrying locomotive vessel and vessel system. This connection system comprises winches secured to the powered locomotive vessel with lines therefrom tied to the cargocarrying vessel and is operable by interrelated winding-in and paying-out of the lines by operation of the winches. This controls lateral movement of the cargo-carrying vessel relative to the locomotive vessel. Not only does this system minimize longitudinal movement between the locomotive vessel and the cargo-carrying vessel, but it also positively provides independently operable cargo-carrying vessel control means which are operable independent of the control means for the locomotive vessel. Thus, the cargocarrying vessel is maneuverable in lateral directions independently of the direction of movement of the locomotive vessel. Thus a cargo-carrying ship used in ice infested waters is provided having optimal split between cargocarrying capability and propulsion capability.</p> |
