Definitions

  • the present invention relates to an apparatus and method for retrieving components from fluid carrying pipelines, and in particular from pipelines carrying pressurised fluids.
  • the present invention relates to pipelines, and more particularly to an apparatus and method for extracting components of pipelines, such as stop valves for controlling fluid flow through pipelines, whilst the pipeline is under pressure.
  • pipelines such as subterranean or over ground pipes for fluid flow, e.g. water and gas pipes.
  • Valves are located at many points along these pipelines, to enable control of the flow of fluid through sections of the pipelines adjacent the valves.
  • many large diameter pipes are located deep underneath roadways, from which smaller diameter pipes branch off, each leading to separate industrial, commercial or residential properties to supply them with e.g. tap water or other non-treated forms of water. Should there be a water leak at one of these properties, a valve in the branch pipe to that property can be operated to stop the flow of water from the large diameter main pipe to the residence along the branch pipe.
  • valves can take one of many forms, but essentially each has some sort of internal barrier member, such as a gate, a ball, a plug, or a disc (in the case of a butterfly valve), which is moveable to allow, to restrain, or to stop the flow of fluid through the valve.
  • barrier members are usually moved by rotating a spindle which extends from the barrier member to the exterior of the valve, towards the ground level above the valve.

  • the spindle of the valve may extend the majority of the way up the open shaft from the valve to the ground surface, allowing the service engineer to use a short key on the end of the long spindle to operate the valve.
  • a cover plate is located in the roadway or footpath above the valve to cover the open shaft.
  • cover plates usually need to withstand the weight of traffic passing over them, including heavy goods vehicles, it is preferred to make the cover plates as small as possible. Small cover plates need not be made as robust as larger ones to withstand the same mass.
  • valves require maintenance, for example to replace a part of the closing mechanism of the valve after it becomes worn or damaged.
  • the valve can be serviced.
  • Conventional valves have a removable 'bonnet' on their upper side (the term 'upper' is used here with reference to the relative orientation of the valve to the road surface above) which is held onto the main casing of the valve by a number of bolts to cover an access chamber in the valve.
  • the closing mechanism of the valve can be accessed and removed for such servicing.
  • the closing mechanism is of a closed-type, such as a plug valve, but such a valve still requires the removal of the outer bonnet to access the plug.
  • valves in question are located deep underground, e.g. 2 to 15 feet (0.6m to 4.5m) below ground level, this is not possible from the road surface. Also, the cover plate in the road surface and the underlying open shaft are too narrow to allow a service engineer to climb down. Thus, maintenance on such subterranean valves can only be carried out after excavation of the earth, tarmac, etc. above the valve, which is of course time consuming, expensive and highly inconvenient to pedestrians and motorists who, as a result of such excavation, may find roads closed or partially blocked with temporary traffic control systems in operation.
