| 摘要 |
The invention relates to an anchor (1), comprising a cavity structure (10) with a top surface (2) and essentially vertical wall means (4) extending downwards from said top surface (2) to form a cavity (10). The anchor has at least one sealable opening (5) in its top surface, and it is provided with means (8) for allowing supply of low density fluid, e.g. gas, to the interior of said cavity structure. It further comprises a bottom surface (3) with an opening (6) or openings for enabling sea water to enter said cavity (10) when the anchor is immersed. The top surface (2) extends in the horizontal plane beyond the periphery of said wall means (4) to form a circumferential flange (11). There is provided a similar flange (12) at the lower end of said wall means (4), said wall means (4) and said flanges (11, 12) thereby forming a receiving portion (13) on said anchor for receiving a windable member (14) therein. It also relates to an electrode station comprising an anchor and electrodes wound onto said anchor. <IMAGE> |
