204 Used software: Scia Engineer CAE Special Projects 5 Introduction Iv-Consult and Bosch Rexroth Systems & Engineering are working together on the design of mechanical lift docks. Iv-Consult is responsible for the engineering of the entire steel and mechanical structures for the Mechanical Lift Dock projects. Bosch Rexroth as main contractor is responsible for the design of the hydraulic and electric installations and the control system. Mechanical Lift Dock versus Ship lift A Mechanical Lift Dock is often confused with a ship lift. It is therefore necessary to briefly explain the difference between the two systems. A Mechanical Lift Dock is used in a shipyard as an alternative to dry-docks, floating docks or slipways. A Mechanical Lift Dock consists of a platform suspended from a number of winch systems. The platform with trestles is lowered under water in the horizontal position, after which a ship takes up position above the platform and the platform is lifted up along with the ship. The ship can than be moved by means of a bogie system and parked on a specific area. Since ships docked on a Mechanical Lift Dock can be moved by a transport system to other specific locations within the shipyard, a Mechanical Lift Dock can service an large number of parking places. In such cases, the costs per repair location are reduced greatly. In The Netherlands, six Mechanical Lift Docks are in operation, namely in Sliedrecht, Alblasserdam, Rotterdam, Den Helder, Amsterdam and Harlingen. A ship lift is a mechanical structure that can move in a water enclosure, approximately the size of a lock chamber. A ship can thereby be raised or lowered Mechanical ships lift dock, Goa This project regards the design of a mechanical ship lift system located in Goa, India. Iv-Consult is the engineering company for the main steel and ship supporting structures. This kind of ‘Mechanical Lift Dock’ is used in a shipyard as an alternative to dry-docks, floating docks or slipways. Mainly it is a platform suspended by large number of winch systems. The ship is placed on movable trailers and transported over rails to a chosen maintenance area. The Goa lift system has a capacity of 6.000 tons and has a size of 120 by 27 meters, the size of a lock. Iv-Consult used Scia Engineer to design the main structure and the various substructures.
