Definitions
- the line-up clamp 72 When the line-up clamp 72 is re-introduced into the new pipe length prior to welding, the line-up clamp 72 first 'docks' with the docking device 74, engages and locks to the plug and socket arrangement, releases docking clamps 76, and positions itself and the docking device 74 at the correct position for accurate welding to take place external to the pipe. [0043] On completion of welding of a new pipe length 78 onto the pipeline 80, the line-up clamp 72 and docking device 74 are retracted (i.e. displaced) to the open end 82 of the new pipe length 78. The docking device 74 is clamped at the open end 82 and un-docked from the line-up clamp 72, breaking the umbilical connection.
- the umbilical cable 70 is routed from gland 86 to a control room 90 and terminated in plant control box 92.
- the plant control box 92 distributes the signals received from umbilical cable 70 to an interpretation workstation 94, which includes an operator display 96 and a video monitoring station 98.
- Water 100 is fed to water storage tank 58 by a water replenishment system 102.
- a human operator in the control room 90 controls the complete inspection cycle by operating interpretation workstation 94.
