www.sea-technology.com March 2017 / st 35 I t is an understatement to say that the art of marine navi- gation has undergone a revolutionary transformation, driven by ubiquitous, highly accurate satellite positioning and advances in digital cartography. In a single lifetime, the state of the art has gone from celestial observations, dead reckoning, noon reports and manual plotting on pa- per nautical charts to modern electronic chart display and information systems (ECDIS) showing real-time positioning and routing on a computer-generated nautical chart. There are several important deadlines for ECDIS imple- mentation looming this year. They include: an extension of the ECDIS carriage requirements to more existing cargo ships in July; a new technical performance standard for ECDIS products in August; and new crew training require- ments in January. This article will focus primarily on the new performance standards, but will also look at the carriage requirement and training issues. It will also touch brie‚y on how ECDIS compliance is being enforced. Implementation of ECDIS Carriage Requirements The ECDIS carriage requirements adopted by the Inter- national Maritime Organization (IMO) in 2011 called for a phased implementation schedule, starting with newbuilds and extending gradually to the existing ‚eet. Currently, all new passenger ships over 500 GT, new tankers over 3,000 GT and new cargo ships over 3,000 GT must be Œtted with an approved ECDIS. Also, all existing passenger ships over 500 GT, tankers over 3,000 GT and cargo ships over 50,000 GT must now be in compliance with the ECDIS carriage requirement. The rule will be extended to all existing cargo ships over 20,000 GT July 1, 2017 and to all existing cargo ships over 10,000 GT July 1, 2018. Note that the regulations require backup for the ECDIS as well—either in the form of a second ECDIS running on a different power supply or a portfolio of up-to-date paper nautical charts. In most cases, it is expected that shipown- ers will opt for a full ECDIS solution so as to eliminate the ECDIS Compliance Requirements New Rules in Effect in 2017 for ECDIS Carriage, Performance By Hans Ottosen ECDIS carriage requirements.
