UNDERWATER EXCAVATION APPARATUS
There is disclosed an improved underwater excavation apparatus. The apparatus comprises at least one means for moving the underwater excavation apparatus, the at least one moving means being provided on or adjacent to the apparatus. The at least one moving means comprise means for orienting, positioning, rotating (e.g. in use around at least one substantially vertical axis and/or at least one horizontal axis), counteracting reactive torque and/or steering the apparatus. The apparatus comprises at least one pair of impellers rotatably mounted in a hollow body and means for driving the impellers. The apparatus comprises a pair of horizontally opposed or symmetrically disposed inlets communicating with a single outlet the outlet, the outlet being disposed vertically downwards substantially midway between the two inlets, in use. The apparatus may therefore be substantially "T" or "Y" shaped in profile.
