Apparatus for deploying equipment in a fluid container or fluid conduit comprises a fluid housing having an outlet aperture, the fluid housing being adapted to be secured to the container or conduit such that the outlet aperture is in fluid communication with an aperture in the container or conduit. The apparatus further includes a piston in the fluid housing dividing the fluid housing into first and second fluid chambers, the second fluid chamber being in fluid communication with the interior of the container or conduit via the outlet aperture when the fluid housing is secured in fluid communication with the container or conduit. The piston is movable within the fluid housing toward the outlet aperture in response to increases of fluid pressure in the first fluid chamber. The apparatus further includes a guide means for guiding deployment of the equipment into the container or conduit. The guide means is secured to the piston, whereby movement of the piston within the fluid housing can move the guide means at least partially into the container or conduit through said outlet aperture. |
