PCT No. PCT/AU92/00160 Sec. 371 Date Dec. 3, 1993 Sec. 102(e) Date Dec. 3, 1993 PCT Filed Apr. 10, 1992 PCT Pub. No. WO92/18379 PCT Pub. Date Oct. 29, 1992.An underwater servicing device includes a substantially hollow housing (30) having an open face (32) whereby the configuration of the open face (32) substantially conforms to the surface of an article to which the housing (30) is to be mounted. A seal (34) is provided about the peripheral edge of the open face (32), as is a pump (42) in fluid communication with the interior of the housing (30) that is capable of evacuating fluid from therewithin and removing such evacuated fluid externally of the device. A mechanism for moving the device from one location on the article to another is also provided, the mechanism being capable of raising the device away from the article. An adjustable air supplier is provided that is capable of allowing air to enter the interior of the housing (30). As water is evacuated from the interior of the housing (30) and air enters, the positive pressure of water external to the housing (30) urges the device against the article such that the seal (34) contacts the article, the further and continuing evacuation of water resulting in a substantially water tight sealing engagement between the seal (34) and the article. |
