Admiralty Information Overlay (AIO)

Enhance situational awareness with the ADMIRALTY Information Overlay, which provides additional navigationally significant information, including possibility for overlaying T&P NtMs directly onto your ECDIS display. AIO is especially useful for digital-only bridge operations, helping mariners visualize updates that may not yet be reflected in ENCs.

Thematic overlays and datasets

All overlays are available via flexible fleet or vessel-based subscriptions, with seamless integration into Navi-Planner or compatible voyage planning software. Fully compatible with Wärtsilä’s Navi-Planner and FOS though may also supplement third-party bridge configurations.

Drawing on decades of in-house cartographic expertise, Wärtsilä offers in-house geo-spatial products that help reduce risks and fines while planning and executing the voyage:

Thematic overlays and datasets
  • Environmental overlay: Visual (and object-attribute based) representation of MARPOL-designated areas, such as Emission Control Areas (ECAs) and Special Areas. Helps with environmental compliance and voyage planning.
  • Advanced Intelligent Routing (AIR): Used together with Navi-Planner, for example, AIR provides automatic generation of port-to-port routes, including complex multi-stop voyages. AIR accounts for vessel parameters, chartered depths, and traffic schemes can dramatically speed up the voyage planning process.
  • Ports database: A comprehensive, structured global port database containing terminal information, pilotage and berth details. Ideal for streamlining route planning, port calls and ETA prediction models.
  • Piracy overlay: Regularly updated zones with incident alerts and threat level visualisation.
  • Bathymetric data overlays: For example, Draft Information System (DIS) for St. Lawrence seaway, provided detailed seabed information to support safe navigation in shallow and complex waters.
  • Weather services: Real-time and forecast meteorological data which supports strategic voyage planning as well as choosing optimal routes while sailing.
