CA 2107917
An underwater servicing device comprising 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. Sealing means (34) is provided about the peripheral edge of the open face (32), as is pumping means (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. Moving means for moving the device from one location on the article to another is also provided, said moving means being capable of raising the device away from the article. An adjustable air supply means 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 sealing means (34) contacts the article, the further and continuing evacuation of water resulting in a substantially water tight sealing engagement between the sealing means (34) and the article.
