A week of underwater inspection

Diving Professionals 24/7

At the request of our client, the Province of Groningen, DTS carried out an underwater inspection on the electrically powered inspection vessel PW18 last week. This ship is used for supervision, enforcement and guidance of shipping and events on the water.

The main purpose of the inspection was to visually assess the state of maintenance of essential parts of the ship. During the inspection we cut a considerable piece of construction cloth from the propeller and propeller shaft on the starboard side, preventing it from moving freely. There was also a piece of cloth on the port side.

And that is just one example of inspections we regularly carry out. For the rest of the week, our divers performed several underwater inspections:

  • The cargo ship Noveno was moored in Hillegom, in the province of Zuid-Holland. We carried out a screw inspection here and found that it was damaged.
  • In the northern main port ‘Eemshaven’ we inspected the bow thruster of container ship Polar Rock as the crew had heard something chattering. Our divers noticed that the bow thruster grilles were loose so they tightened them again.
  • In the port of Lauwersoog we cleared the propeller of a fishing cutter from Urk. As we often see, a piece of rope was tangled in it.
  • We also carried out an inspection in Lauwersoog at the threshold of the storm surge gates of the Robbengat lock and carried out some work on a fish migration gate.

Naturally, an extensive report has been drawn up of all these inspections, supplemented with images.
