PRECAUTIONARY AREAS
Vessels entering the IJMUIDEN precautionary areas should navigate with 
extreme caution as vessels on route to and from TSS off Texel, IJmuiden, the 
Westerschelde and Europoort may be merging or crossing.

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.

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.

VESSEL REPORTING
For details of the IJmuiden Vessel Traffic Service, see the Netherlands Coast 
Pilot (HP1) or ADMIRALTY List of Radio Signals.

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.

OIL AND GAS FIELDS
Production platforms and associated structures, including tanker moorings, 
storage tankers and platforms on pipelines, generally exhibit Mo(U) lights, 
aircraft obstruction lights, and audible fog signals. Unauthorized navigation is 
prohibited within 500 metres of all such structures, including storage tankers 
which can swing about their moorings. Tankers manoeuvring in the vicinity of 
platforms and moorings should be given a wide berth. For further information 
see the Netherlands Coast Pilot (HP1) or the Mariner's Handbook.

FIRING PRACTICE AREA
For information concerning Firing Practice Areas, see the Netherlands Coast 
Pilot (HP1) and ADMIRALTY Sailing Directions.
