Abstract: An offshore construction arrangement in which a platform is provided with raisable and lowerable support legs which engage a substructure resting on the sea bed. The parts lie on one another in a solid support surface and engage over one another while maintaining a funnel-shaped gap. Spring elements are located between side walls of the substructure and end portions of the legs, and the spring elements are supported on one of the side walls. The spring elements are displaceable in horizontal and vertical directions, and they are constructed as leaf springs arranged in a funnel. The leaf springs protrude beyond the rim of the funnel and are pre-bent inwardly. The leaf springs, furthermore, may be supported by lateral springs, and an auxiliary funnel may be used to receive the spring elements while being exchangeably arranged in the first-mentioned funnel. The spring elements may be in the form of several blocks of elastic material and spaced from each other.
