Abstract
A device for transporting and placing a bridge (1) of an offshore oil rig onto a floating or stationary mounting structure (3). The device has two parallel floating barges (10) for mounting the bridge (1). Each barge has a set of vertical movement rams (11) that move the bridge between a position of bearing on the barges (10) and a position of bearing on the structure (3). Each barge (10) has at least one assembly (15) for controlling the roll of each barge (10) in relation to the bridge (1) during the placement of the bridge onto the mounting structure (3). The assembly includes at least two rams (16) that are carried by the barge (10) and are located on both sides of the longitudinal axis of the barge (10). Each ram (16) is connected to the bridge (1) by a connecting member (17) that has rigid pull and flexible compression.
