Abstract: A construction kit for a multispan military or army bridge, comprising a plurality of bridge elements (1) which carry track lanes (10, 11), and coupling devices (15, 16) for coupling a plurality of bridge elements together to form a row of such elements, and further comprising a plurality of ramp sections (2, 3) which form drive-on and drive-off ramps on the bridge construction. The construction kit is characterized in that it comprises a crane carriage (4) for lifting a bridge element into a position in which it can be coupled to another bridge element; locking devices for coaction with the locking devices (15, 16) when coupling to bridge elements together; and support-leg pairs (120, 121) which function to support the mutually coupled bridge elements. The whole of the construction kit can be accommodated on conventional trucks or lorries (8). The invention also relates to the actual bridge element, crane carriage, locking devices and support-leg pairs themselves.

Abstract: An anchorable, floating platform intended to be used for extraction of oil and gas from the bottom of the sea and comprising an upper portion over the water surface, a lower portion under the water surface, and a column which connects the upper portion with the lower portion and which is designed to allow transportation of persons between the two portions. The lower portion is surrounded by a ring of ballast tanks which extend below the lower portion, so that a bowlshaped space is formed between the ballast tanks and the lower portion, and anchor wires are arranged to pass the ring of ballast tanks for holding the platform.
