摘要： An artificial island in the form of a mobile offshore platform comprises a pontoon and at least three columns that are movable vertically relative to the pontoon to support the pontoon in lowered position or to float with the pontoon in raised position. The pontoon is sectional and the sections are pivotally interconnected for horizontal swinging movement relative to each other so that the sections can occupy different positions relative to each other when the platform is being transported and when the platform is emptied. Each section carries at least one of the columns. A suction dredge is carried by the pivot between two adjacent sections.

摘要： A hopper barge with a plurality of discharge openings spaced apart longitudinally along its bottom has a valve for each opening, the valves being interconnected in a series for simultaneous movement lengthwise of the barge. The valves are actuated by wedges and abutments to move, when closing, first horizontally and then upwardly, and when opening, first downwardly and then horizontally. Hydraulic jacks at opposite ends of the series operate alternately so that the series is always in tension when moving. The discharge openings are bordered by resilient sealing strips that extend toward the valves and that are faced with a wear-resistant material.
