ECDIS by Transas 

Our ECDIS delivers proven usability while fully integrated into our fleet operations solution

ECDIS is a computer-based navigation information system compliant with the latest International Maritime Organization (IMO) regulations and is used as an alternative to paper nautical charts.

An ECDIS system displays the information from electronic navigational charts (ENC) and integrates position information from the Global Navigation Satellite System (GNSS), gyrocompass, speed log, other navigational sensors, radar and automatic identification systems (AIS).

Wärtsilä delivers a full range of type-approved ECDIS solutions that can be stand-alone or part of the Integrated Navigation Systems or Multifunctional Display i.e. Radar, Conning, Bridge Alarm Management, Track Control in one workstation.

  • Pre-calculated motion vectors: Even before the operator acquires a target, Transas Navi-Radar 4000 already selects potential targets and provides you with instant vector and object data.
  • Target association: Built-in filters can associate any AIS and ARPA target to provide reliable, real-time data, selected by the operator.
  • Filtering lost targets: In heavily trafficked areas, focus is key to avoiding dangerous situations. Operator-defined target filters warn you only when necessary.
  • Trial Manoeuvres and Curved Heading Line: Real-time calculations and presentation strengthen any decision made by the officer.
  • Chart Radar: Efficient multi-loading and display of electronic charts where ENC/SENC or TX-97 charts can be presented as an underlay simultaneously with individually created MAPs.
