In line with STCW requirements, navigating officers are required to maintain competence in their watchkeeping routines and practices when using ECDIS. The ECDIS Procedures Guide, 2020 Edition provides a framework, as well as supporting background information and checklists, to aid officers in fulfilling these requirements. It helps companies implement best practice in the use of ECDIS on board their ships.

The 2020 Guide has been updated to reflect the latest software and procedural changes. In addition, the 2020 guide features:

  • An introduction to the new S-Mode (approved by the IMO in 2019) and software updates affecting all new and updated ECDIS systems from 2020 to 2024.
  • the new Inspection question banks for 2020 ECDIS Audits (concentrating particularly on Safety Contour, UKC/CATZOC and ECDIS cyber security vulnerabilities)
  • complete Type Specific Familiarisation for all 21 Manufacturers updated for 2020
  • a simple guide to CATZOC reliability
  • an example of a full ECDIS Navigation Audit required by owners to evaluate SMS
  • the Transition to S-100
  • ECDIS Procedures for Cyber security
  • details of countries that include T&Ps in weekly updates
  • AIO Version 2 update and ECDIS manufacturer Type Specific compatibility list
  • pre-port arrival – PSC ECDIS preparation activities (additional 30 minutes added)

This Guide provides recommendations for how ECDIS should be configured and used as a ship’s primary means of navigation.

To achieve compliance with international regulations, a ship may navigate with ECDIS as its primary means of navigation if:

  • Sufficient official data adequate for the intended passage is installed (ENC and RNC)
  • the installed ECDIS is type approved
  • a second type approved ECDIS is installed as a backup (or a flag State approved portfolio of paper charts is carried
  • adequate generic and type specific training has taken place
  • any additional requirements laid down by the flag State are fulfilled.

When used correctly, ECDIS enhances navigation and improves situational and spatial awareness compared to navigation using paper charts. It is a system that can display the past, present and predicted position of a vessel by utilising all available sensor information. However, the techniques required to use ECDIS differ, in part, to those required when using paper charts. For safe navigation using ECDIS:

  • All ECDIS operators must have completed generic and type specific ECDIS training
  • official and up to date ENCs must be used
  • all available sensors and navigation aids to support accurate, safe navigation must be used to prevent the over-reliance on any one sensor
  • all techniques and equipment to cross-check GNSS derived positions must be used
  • dead reckoning (DR) and estimated position (EP) should be used in the event of GNSS equipment failure
  • there must be an appropriate configuration and an understanding of all safety settings.
