VESSEL REPORTING
For details of the Maas Approach and Scheveningen Vessel Traffic Service, see the 
Netherlands Coast Pilot (HP1) or Admiralty List of Radio Signals.

TRAFFIC SEPARATION SCHEMES AND ROUTEING
For the latest information on individual schemes and IMO mandatory routes for 
certain tankers and other vessels, see the Netherlands Coast Pilot (HP1) or 
Admiralty Sailing Directions.

SUBMARINE CABLES AND PIPELINES
Mariners are advised not to anchor or trawl in the vicinity of submarine cables and 
pipelines. Pipelines are not always buried and their presence may significantly reduce 
the charted depth. They may also span seabed undulations and cause fishing gear to 
become irrecoverably snagged, putting a vessel in severe danger.

HELICOPTER OPERATIONS
Pilot transfers by means of helicopter may be expected in the MAAS CENTRE 
precautionary area. For further details see the Netherlands Coast Pilot (HP1) or 
Admiralty List of Radio Signals.

OBSTRUCTIONS (SCHEVENINGEN APPROACH)
(52°07’N 4°14’E)
Submarine pipelines, with vertical tubes projecting up to 3.5m from the seabed 
extend up to 2.5km from the shore.

DEPTHS AND AIDS TO NAVIGATION
The channels and depths shown on this chart are subject to frequent change. 
The buoyage and other aids to navigation are adjusted accordingly. For the 
latest information see Notices to Mariners or consult the pilotage authorities.
