FIELD: construction. ^ SUBSTANCE: method for assembly of support columns of self-lifting floating drilling vessel comprising water-displacement body with ballast cisterns, equipped with portals of lifting mechanisms, consists in subsequent assembly of support columns sections near construction fill by means of weight-lifting crane. Assembly of support columns sections is carried out when vessel body floats, at the same time weight-lifting crane is previously installed on construction fill, and technological stops are mounted on support columns of specified self-lifting drilling vessel, which interact with portals of lifting mechanisms in order to hold support columns in body without their resting on soil. Levelling of vessel body position in process of support columns assembly is carried out by reception of liquid ballast into body cisterns. ^ EFFECT: possibility of anticipatory assembly of support columns without preliminary assembly and adjustment of lifting devices. ^ 1 dwg |
