The invention relates to an oscillating installation installed at a fixed site in a body of water, comprising a shaft which rests on a heavy base, which itself bears on a bed, and which supports a platform at its upper part, the shaft is connected to the base by a ball-joint consisting of two hemispherical caps. The shaft is loaded in such manner that the joint is always under compression. Examples of forms of joint comprising packings between the two caps are described. The invention also relates to a method of laying such an installation, the latter being conveyed by flotation to the site, and the correction of listing by the use of caissons disposed along the shaft. |
