VESSEL TRAFFIC SERVICE (VTS)
For procedures and working details of the Den Helder Vessel Traffic Service, 
see Netherlands Coast Pilot HP 1 or Admiralty List of Radio Signals.

CABLES AND PIPELINES
Mariners are advised not to anchor or trawl in the vicinity of
cables and pipelines. Pipelines are not always buried and their presence may
effectively reduce the charted depth by up to 2 metres. They may
also span seabed undulations and cause fishing gear to become
irrecoverably snagged, putting a vessel in severe danger. See the
Netherlands Coast Pilot (HP 1).

TIDAL STREAMS
Attention is drawn to the strong tidal streams in
these waters. For tidal streams and tidal information
see HP 33 Tidal heights and streams for coastal 
waters of the Netherlands and adjacent waters and
HP 33D-NLTides published by the Netherlands Hydrographer.
