The inspection of the cooling water outlet

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.
