Electronic Navigational Charts (ENCs)

Electronic Navigational Charts (ENCs) are digital vector charts produced to International Hydrographic Organisation (IHO) standards. As a reseller of ENCs and other digital chart products, Chronicles Energy Services Ltd can recommend and supply the best solution for your vessel or fleet needs.

Our team of digital product experts are always available to assist with migration from paper to electronic products and services if required. We will advise on the most appropriate products, with options that include ENCs, through to ENCs mixed with various backup solutions including paper.
Once electronic indexes have been agreed upon, our experts ensures that permits and the ENC cells themselves are supplied to the ship promptly. Regular coverage reviews take place to deal with changes to voyage and additional ENC coverage.
Permit expiry reminders are supplied and a pro-active approach to renewals and provision of data is taken. This is especially important with the current choice of permit durations.
