VESSEL TRAFFIC SERVICE (VTS) Ch 1 Eemshaven Radar Ch 66 Harbour-services Delfzijl/Eemshaven For procedures and working details of Delfzijl/Eemshaven and Eems Vessel Traffic Service, see Netherlands Coast Pilot HP 1 or Admiralty List of Radio Signals. HIGH SPEED CRAFT Take into account the traffic of high speed craft between Emden and Borkum. 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).
