ABSTRACT:
Split hopper vessel comprising two half hulls which are pivotably connected to each other by a pivot shaft which extends at a high level parallel to the longitudinal axis of the ship. Both half hulls are furthermore connected to each other by means of cylinder pairs installed at an interval at a distance below the pivot shaft in a directiontransverse to the pivot shaft. The housings and the piston rods of each pair of cylinders are by cylindrical bearings connected to a respective axle, in common for both housings and for both piston rods, which axles themselves are, centrally between the housing bearings and the piston rod bearings connected to the respective part of the ship by a self adjusting bearing. The fluid lines between the rod sides on the one hand and the piston sides on the other hand of each pair of cylinders are embodied as rigid conduits, which are connected to both sides of one single remotely controllable locking- and safety valve for each pair of cylinders.
