Welcome to WECDIS.com, the online home of the naval ECDIS community. The term WECDIS stands for "Warship Electronic Chart Display and Information System" and is also known by some nations as ECDIS-N, where the N stands for "Navy".

ECDIS systems are the future of navigation at sea, following mandation by the International Maritime Organisation (IMO). In a rolling programme from July 2010, all seagoing vessels above a certain tonnage will be required to install an ECDIS. More information about civilian ECDIS mandation is available on the ECDIS Ltd website.

The British Royal Navy (RN) and Royal Fleet Auxillary (RFA) were the first military organisations in the world to fit NATO-standard WECDIS systems to their warships and auxillaries. The initial contract was signed on January 8th 2004.

A rolling installation programme began in July of that year and WECDIS was fitted, first to the capital ships, destroyers and frigates and then in the various survey and minor war vessels.

Since the Royal Navy, other nations have followed suit, including US Coast Guard (August 2007), Royal Australian Navy (October 2007), Brazilian Navy (February 2008) and Royal Netherlands Navy (August 2009).

Possible functions of a WECDIS system may include:


"Having recently completed ECDIS Limited's ECDIS Course I have adopted a different perspective and believe that ECDIS has the potential to provide suitable situational awareness, coupled with its other functionalities to assist in navigational safety and collision avoidance. ECDIS Limited's ECDIS Course covers the legal aspects pertinent to the use of ECDIS for navigation; the different types of Charts and Electronic Chart Systems; and the data available from the system. The majority of the program however is dedicated to practical exercises, ensuring that a proper understanding of the system's capabilities is achieved. Pleasant and knowledgeable course facilitators, ample and modern workstations, in comfortable surroundings allow for individualized, relevant training, in a relaxed environment."
