Abstract

The present invention relates to an underwater work assembly and a method for anchoring the underwater work assembly into the bedding of lake, sea or river. The work assembly comprises the following components: a service platform which can be laid down, and a plurality of supporting legs. The plurality of supporting legs are mounted so that the supporting legs can be adjusted on the service platform for being positioned on the bedding of the lake, sea or river, and furthermore can be moved in and out by means of an actuating cylinder relative to the service platform. For improving anchoring, the invention suggests that at least one supporting leg is rotatably mounted relative to the service platform; a rotation driver which faces the supporting leg is equipped; the rotation driver is used for performing rotation driving on the supporting legs for screwing into the bedding of the lake, sea or river.

Description

technical field [0001] The present invention relates to an underwater working assembly, in particular for creating holes in the bed of a body of water, having: a service platform that can be lowered; and a plurality of support feet mounted so as to be adjustable on the service platform They are intended to be positioned on the bed of the body of water and can be moved in and out relative to the service platform by means of jacks. [0002] The invention also relates to a method for anchoring a subsea working assembly with a service platform into a bed in a body of water, wherein the service platform is lowered into the water and positioned on the bed of the body of water with a plurality of support feet, In this case the support foot is adjusted by means of a jack. Background technique [0003] The general prior art is known, for example, from EP 2 322 724 A1 or GB 2 469 190 A. With this known underwater drilling arrangement, a service platform is provided which includes ad...
