Offeshore Power installations
network allows the constructors and operators of Offshore Power
generation installations to protect the installations during the
construcvtion and operation phases.
Consider a vessel approaching an offshore wind farm at night. Having an AIS Aid to Navigation [AtoN] transponder on some of the wind turbines will make these visible to the vessel if the mariner is watching the AIS display.
system detects that the vessel is approaching the wind
farm and then sends an addressed message via the MariWeb™
AIS network to the vessel indicating that the vessel is approaching the
wind farm. With the same AIS network infrastructure, the MariWeb™
system is able to mark all offshore wind turbines with a virtual Aid to
On the shore side, the operator of the wind farm is able to see that the vessel is approaching the wind farm and could enter the protected area.
When the addressed AIS warning message is sent to the vessel, the operator sees that it has been sent and also sees that a copy of the message is recorded in the audit trail. The audit message is received from a separate AIS receiver and is used to make sure that the warning message was actually transmitted to air.
All the while, the wind farm operator is collecting the AIS data that will show the actual path taken by the vessel and is able to display this over the latest navigational charts as well as the engineering drawings of the offshore wind farm that are stored and displayed on the same GIS system that is built into MariWeb™.
