The digital landscape of maritime navigation is constantly evolving, and for mariners using UKHO (United Kingdom Hydrographic Office) products, staying up-to-date is a matter of both safety and regulatory compliance. 🛳️ The Modern Navigator's Toolkit
Modern vessels have transitioned from heavy paper volumes to ADMIRALTY Digital Publications (ADP) and e-Nautical Publications (e-NPs). These e-books are encrypted versions of their paper counterparts, including essential guides like Sailing Directions and the Nautical Almanac. 🔄 The Shift from FTP to File Share
For years, the primary method for manually fetching these updates was the UKHO FTP site. Mariners would log in using a public credential (ukhopublic) to download weekly update files.
However, the UKHO has retired the old FTP site. All digital product updates—including those for AVCS, ADP, and e-NPs—have moved to a more modern, secure platform called the ADMIRALTY File Share Service (FSS). Key Update Methods

The United Kingdom Hydrographic Office (UKHO) serves as the primary charting authority for the UK, providing navigational products crucial for the safety of maritime operations. Historically, this data was disseminated via paper charts and physical mail distributions. However, the advent of the digital era has necessitated a shift toward Electronic Navigational Charts (ENCs) and digital publications.
A critical component of this digital infrastructure is the mechanism for data delivery. While web portals exist for manual downloads, high-volume commercial users and Value Added Resellers (VARs) rely on automated, bulk data transfer methods. This paper explores the use of File Transfer Protocol (FTP) as the backbone for disseminating ukhogovuk digital product updates and ENP (Electronic Navigational Publication) files.
ENP publications refer to structured digital product updates related to emergency planning, national resilience, and public safety notices. These often include: ftp ukhogovuk digital product updates enp publications
For users looking to access these resources programmatically, the standard path structure usually follows the convention:
ftp://[host_address]/digital/product_updates/enp/publications/
Users are advised to consult the gov.uk developer documentation for the specific whitelisting requirements if accessing the FTP via automated scripts from commercial IP addresses.
This is a brief story designed to explain how UKHOGOVUK’s Digital Product ecosystem integrates with ENP (Electronic National Publication) updates and delivery systems. The team at
knew that for their clients, data wasn't just information—it was a lifeline. Their latest Digital Product Update
was designed to bridge the gap between complex regulatory requirements and seamless user experience. At the heart of this update was the integration of ENP Publications
. These electronic records needed to be distributed to global partners instantly, ensuring everyone from site managers to compliance officers had the most current versions of safety and operational manuals. To handle the heavy lifting, the engineers refined their FTP (File Transfer Protocol)
architecture. Instead of manual uploads that risked corruption or delay, the new system utilized automated "hot folders." The workflow was simple: generates a new publication or amendment. UKHOGOVUK’s digital engine packages the update with metadata. server triggers a secure push to client workstations.
"It's about removing the friction," the lead developer explained during the launch. By syncing ENP Publications via a hardened pipeline, UKHOGOVUK ensured that their Digital Products The United Kingdom Hydrographic Office (UKHO) serves as
were never out of date, keeping their users compliant and informed with zero manual effort. Key Takeaways Automation: ENP updates move via FTP without human intervention.
The UK Hydrographic Office (UKHO) has recently updated the way mariners access and update ADMIRALTY e-Nautical Publications (e-NPs) and other digital products. Most notably, the traditional UKHO FTP site has been retired in favor of the more modern and secure ADMIRALTY File Share Service (FSS). Key Updates for e-NP Users
Transition from FTP to FSS: Files previously hosted on the public FTP server (using the ukhopublic login) are now exclusively available via the File Share Service.
Single Edition Availability: To ensure safety and compliance, only the current edition of any e-NP (e.g., e-NP66A) is hosted on the FSS at one time. When a new edition is released, the previous version is immediately removed.
Update Package Formats: Weekly updates for e-NPs are now packaged as ZIP files (e.g., UCFI2023090.zip) and are available for 28 days from their release date.
Software Downloads: The latest ADMIRALTY e-NP Reader software (versions 1.3 and 1.4) can be downloaded through the FSS to manage electronic books and apply Notice to Mariners (NM) updates. How to Access Digital Updates
Register for FSS: New users must create an account on the ADMIRALTY File Share Service to access digital product folders.
Locate e-NP Files: Within the FSS, users can search for specific publications or navigate through the Digital Product Updates > e-NP > Publications folder hierarchy. ENP stands for Electronic Notice Publications
Manual Updates: If not using the ADMIRALTY e-Navigator for automatic updates, mariners should create a local folder named "Publications" on their bridge computer to store and apply downloaded PDF editions.

The United Kingdom Hydrographic Office (UKHO) has phased out its legacy FTP server (ftp://ukho.gov.uk/) in favor of the modernized File Share Service (FSS) for distributing ADMIRALTY e-Nautical Publications (AENP) updates. This transition streamlines the update process, ensuring compliance with SOLAS requirements by allowing users to download software and weekly updates via a secure, web-based platform rather than manual FTP navigation.

ENP stands for Electronic Notice Publications. These are machine-readable versions of statutory notices, planning applications, and regulatory changes. Unlike PDF gazettes, ENP formats are often XML, JSON, or CSV structured data used to update internal case management systems automatically.
Modern UK government digital products (e.g., GOV.UK Notify, Pay, and Registers) release continuous updates. These include security patches, schema changes for APIs, new feature flags, and deprecation notices.
The core of this update lies in the restructuring of the ENP directory. Historically, finding specific energy datasets—ranging from quarterly fuel prices to regional energy consumption statistics—required navigating complex folder structures.
The updated digital product introduces a flattened, logic-based taxonomy. Users accessing the FTP servers for ENP content will now find publications organized by:
This aligns with the broader UK government strategy to make data "open by default," reducing the friction of Freedom of Information (FOI) requests by proactively publishing raw data.
