Abstract
Floating apparatus for performing operations, such as dredging and drilling, on and in a bottom under water subject to violent motion. The apparatus comprises a working platform provided with legs vertically adjustable to the depth of the bottom by adjusting means. Each leg is flexibly connected at least at two vertically spaced places to parts of the apparatus formed integrally with the platform. The connection of a leg at the higher of the two places is effected by means for taking up rocking movements of the working platform, and at the lower of the two places by connecting members springing and/or dampening in two perpendicular horizontal directions, while the means adjustable in the vertical direction for connecting the leg to the working platform are also of resilient or dampening construction.
Claims7
Floating apparatus for performing operations such as drilling and dredging in the bed of a body of water subject to turbulent movement, the apparatus including a working platform, a plurality of legs for supporting said platform from the bed of the body of water, means for supporting each leg for vertical movement with respect to the platform, and means for vertically adjusting each leg according to the depth of the bed from the surface of the water, wherein the improvement comprises:
- means for pivotally connecting each leg support means to the platform at a first level of the platform and
- means extending between each leg support means of at least a pair of said legs and the platform in two mutually orthogonal directions at a second level of the platform, spaced vertically from the first level, for resiliently damping pivotal movement between said legs and the platform;
- and
- said means for vertically adjusting each leg comprises means for selectively resiliently damping vertical movement of the leg with respect to the platform.
