<p>Apparatus (10) for deploying equipment (54) in a fluid container or fluid conduit (12), comprises a fluid housing (14) having an outlet aperture (48), the fluid housing (14) being adapted to be secured to the container or conduit (12) such that the outlet aperture (48) is in fluid communication with an aperture (36) in the container or conduit (12). The apparatus (10) further includes a piston (28) in the fluid housing (14) dividing the fluid housing (14) into first and second fluid chambers (38, 40), the second fluid chamber (40) being in fluid communication with the interior of the container or conduit (12) via the outlet aperture (48) when the fluid housing (14) is secured in fluid communication with the container or conduit (12). The piston (28) is movable within the fluid housing towards the outlet aperture (48) in response to increases of fluid pressure in the first fluid chamber (38). The apparatus further includes a guide means (16) for guiding deployment of the equipment (54) into the container or conduit (12). The guide means (16) is secured to the piston (28), whereby movement of the piston (28) within the fluid housing (14) can move the guide means (16) at least partially into the container or conduit (12) through said outlet aperture (48).</p> |
