The inspection of the cooling water outlet from the plant under the access channel to the Waddenzee-side.

The goal of the inspection was:

  • To assess over which length the pipeline is not filled with sand or sediments;
  • To assess the marine growth on the surface;
  • To determine visually the condition of the pipeline;
  • To record the inspection real time and on USB;
  • To report the inspection.
  • To collect as much as possible information to estimate the costs for cleaning the pipe.
  • To collect samples of the mud for determining the quality for disposal.
  • Main safety issues in this project were:
  • The access on one side;
  • The length of 375 m of the pipeline;
  • The maximum depth of -/- 17 m datum NAP;
  • Confined space diving.
