The National Hydrographic Agency will release three new nautical charts covering the approaches to Calabar, Jamestown and the Port of Calabar on October 1, 2026, as Nigeria expands domestically produced navigational coverage of its waters.
The release will coincide with the planned withdrawal of two United Kingdom Hydrographic Office Admiralty charts currently covering the Calabar area.
The new products are NG5514, Approaches to Calabar; NG5515, Jamestown; and NG4255, Port of Calabar.
The NHA said the charts provide updated navigational information from the approaches to Calabar through Jamestown and into the port limits.
Paper versions were technically assessed by the UK Hydrographic Office for consistency with adjoining coverage, while the corresponding Electronic Navigational Charts were independently validated by the International Centre for Electronic Navigational Charts.
The NHA and UKHO are coordinating the transition to avoid gaps in authoritative chart availability for mariners.
Hydrographer of the Federation Rear Admiral O.O. Fadahunsi said the release demonstrated Nigeria’s growing ability to survey and chart its waterways to internationally recognized standards.
The Calabar maritime corridor is an important route for commercial shipping and other maritime activity in Nigeria’s eastern waters.
The agency said the new products form part of a broader programme to modernize the national chart portfolio through continuing surveys, new paper charts, electronic charts and regular updates.
