In one embodiment, a female wedge mount is attached to a first surface vehicle. The female wedge mount has a concave contact surface including three or more female contact surface segments an at least two female wedge slots. A male wedge mount is attached to the second surface vehicle. The male wedge mount has a convex contact surface including three or more male contact surface segments and at least two male wedge slots that are aligned with the at least two female wedge slots, respectively, when the convex contact surface of the male wedge mount and the concave contact surface of the female wedge mount are in aligned contact with one another to form an adjacent connection between the first and second surface vehicles. A mechanism includes at least two pins that are movable along the at least two male and female wedge slots, respectively, between unlocked and locked positions.

A fast installing self-propelled pontoon bridge consisting of the entrance vehicle (A-1), a vehicle-float which is connected with the entrance vehicle and an exit vehicle, an exit vehicle, and an anchoring vehicle to keep the bridge in one place, being equipped with an anchor to keep the pontoon bridge to resist the water flow.

A vessel including a boom construction, especially a gangway construction, for transferring persons and/or cargo from said vessel to an offshore object or vice versa. The boom construction includes an elongated mast structure extending in a direction substantially upwards from a deck of said vessel. Said mast structure is pivotally mounted with respect to a hull of the vessel in a manner such as to be pivotable with respect to said hull about a single pivot axis only. The boom construction further includes a boom, especially a gangway, which is connected to the mast structure and which extends from the mast structure in a substantially sideward direction. Furthermore, the boom construction includes at least one actuator for pivoting the mast structure such as to compensate for at least a part of a roll movement of the hull of the vessel.

The invention is about fast installing self-propelled pontoon bridge. The pontoon bridge consists of the entrance vehicle (A-1), vehicle-floats (A-2) connecting the entrance vehicle and the exit vehicle of the bridge (A-3). The anchoring vehicle (A-4) is to moor the bridge to the river bed when installing/uninstalling the bridge. The bodies of the portions are main floats; the vehicles are designed in a way that they can both move on the ground and in the water. For parts associated with moving on the ground, the conventional axles are replaced by the wheels directly driven by hydraulic motors (1). The vehicles' structures are modified to fit new operation methods. The vehicles act as joints. The vehicles are designed for straight line connection; and, the soft connecting is carried out before entering the water. Each vehicle can cross the river by itself. Once the exit vehicle of the bridge is approaching the opposite river bank, all the vehicles are connected. Due to the novelty design, the installing/uninstalling required a person, in the cab, for each vehicle; and much less time consumed.
