Digital Navigation Compliance

Taking the hassle out of full compliance, we look after all of your OnBoard requirements to ensure you are meeting IMO regulations and are always ready to set sail.

International Telecommunication Union (ITU) is the United Nations specialized agency for information and communication technologies (ICT). ITU allocates global radio spectrum and satellite orbits, develops the technical standards that ensure networks and technologies seamlessly interconnect, and strives to improve access to ICTs to underserved communities worldwide.

ITU is committed to connecting all the world's people, protecting and supporting everyone's fundamental right to communicate.

There are three publications that are essential on board any ship in order to meet compliance requirements.  

·    List IV - List of Coast Stations and Special Service Stations

·    List V - List of Ship Stations and Maritime Mobile Service Identity Assignments

·    Maritime Manual - Manual for Use by the Maritime Mobile and Maritime Mobile-Satellite Services (Maritime Manual)

Carriage requirements for publications on board ships are defined by regulations of IMO, Flag states and ship’s Safety Management System (SMS) manual. Basic requirements are specified in the IMO MSC-MEPC.2/Circ.2 “IMO requirements on carriage of publications on board ships”

The list of publications, to be carried onboard depends on the ship type, ship flag and shipping company SMS. Different vessels require different publications, depending on vessel type, flag, trading pattern, cargo and shipping company policy

The LEO Managed Service (LEO MS) is a ChartWorld service of delivery and maintenance of ships’ library of technical publications in accordance with the customer requirements. Once selected publications are included in the ship’s inventory, all new editions and new publications that replace existing ones, are delivered onboard the ships subscribed to the LEO Managed Service (LEO MS).

ACES is an official SOLAS ENC data service by ChartWorld, one that supports the various data formats. ACES’s convert the complete Admiralty Vector Chart Services (AVCS) dataset into (S)ENC, for fast, simple and error-free data supply. ACES also provides the Admiralty Information Overlay (AIO); this enables your ECDIS to digitally display Temporary & Preliminary (T&P) data, as well as displaying additional electronic notices (eps), on your screen. For ECDIS’s that are unable to display the ACES (S)ENC format, we supply the Admiralty Vector Chart Service (AVCS). ACES are the ideal electronic charting product for an easy and cost-effective approach to paperless navigation.

ACES also meets SOLAS chart-carriage requirements, as long as the charts are kept up-to-date and displayed using a type-approved Electronic Chart Display and Information System (ECDIS.)

We are able to offer you the The ADMIRALTY Vector Chart Service (AVCS), which is the world’s leading digital maritime charting service on offer. There are over 15,000 official Electronic Navigational Charts (ENCs); these help bridge crews to navigate safely and efficiently, whilst meeting Flag and Port State requirements.

Key features of AVCs:
