Abstract

A method is provided for mounting a deck superstructure, comprising at least one concrete girder and/or beam, on a supporting structure intended to operate in marine surroundings. The supporting structure comprises at least one column which extends above sea level and the method comprises the steps of bringing the deck superstructure, either as a unit or in sections, in position relative to the column, hoisting the deck superstructure up to the final position thereof using cables and a jacking system, and tensioning the cables upon the arrival of the deck superstructure in its final position. The lower ends of the cables are permanently anchored to the deck superstructure while the upper ends of the cables are connected to hoisting and tensioning devices arranged on top of the column. The lower ends of the cables are arranged within the concrete girder and/or beam in such a way that the cables, upon tensioning, form an integral part of the static system of the deck superstructure, therby providing both vertical and shear reinforcement.
