ADMIRALTY Total Tides (ATT)

Take advantage of the tides.

ATT helps crews take full advantage of favorable tides – allowing them to calculate safe clearance and making departure and arrival planning easier.

Reducing risks to your ship, cargo and crew, ATT enables quicker and more informed decisions to be made on the bridge regarding key commercial and safety issues.

It also brings global tidal tables and stream data together, complete with instant calculation, helping crews to make tidal height predictions for more than 7,000 ports and 3,000 tidal-stream stations worldwide.

Instant port predictions

ATT enables your crew to select and calculate tidal heights for multiple ports for up to 7 consecutive days.

Improved situational awareness

Maximise situational awareness through real-time tidal predictions, which can be overlaid on your crew’s chart-based display and updated every 60 seconds.

Compliance with SOLAS requirements

ATT is widely accepted as meeting SOLAS carriage requirements for height, time and tidal streams worldwide, meaning ongoing safety and compliance. The UKHO database of over one million tidal constants is updated on an annual basis in line with the ADMIRALTY Tide Tables. If your crews use ATT to meet carriage requirements for tidal references, they must have the latest database version.

Providing greater confidence, ATT:

-       Helps crews calculate safe clearance

Crews can calculate and view safe clearances based on a ship’s draft, masthead and under-keel clearance allowance.

-       Enables easier planning

Departure and arrival-time planning is simplified, with prediction results displayed in user-friendly graphical forms.

-       Provides worldwide coverage

Crews can make tidal height predictions for ports tidal stream stations around the world.

ADMIRALTY Digital Publications (ADP)
Bringing simplicity, flexibility and speed to passage planning and navigation

ADP includes:
- ADMIRALTY Digital List of Lights – the world-leading source of navigational light and fog signal information
- ADMIRALTY TotalTide – the world’s most comprehensive, real-time tidal prediction program, bringing global tidal height and stream data together
- ADMIRALTY Digital Radio Signals Volume 6 – essential maritime radio communications information for 3,600 service locations worldwide

ADP offers:
- Greater efficiency, faster updating and more flexible information access – helping busy bridge crews to make quicker, more informed decisions
- Approval by flag states of the majority of the fleet trading internationally as meeting carriage compliance requirements
- Up-to-date information – providing greater assurance for crews, operators and owners alike

What is ADP?
ADMIRALTY Digital Publications (ADP) are computer-based versions of the UKHO’s market-leading paper-based nautical reference guides – ADMIRALTY Nautical Publications. ADP applications are widely accepted as meeting SOLAS carriage requirements for nautical reference guides, and contain the same information as their paper equivalents.

The ADP range currently includes:

ADMIRALTY Digital List of Lights (ADLL) – an advanced source of navigational light and fog signal information, covering over 70,000 individual light structures worldwide.

ADMIRALTY TotalTide (ATT) – the world’s most comprehensive tidal prediction program, bringing global tidal height and stream data together. It allows crews to make tidal height predictions for more than 7,000 ports and 3,000 tidal stream stations worldwide.

ADMIRALTY Digital Radio Signals Volume 6 (ADRS 6) – essential maritime radio communications information for 3,600 service locations worldwide, including pilot services, vessel traffic services and port operations.

The advantages of the digital applications
While ADP provides exactly the same information as traditional ADMIRALTY paper-based reference guides, it offers numerous additional benefits.

The digital applications provide greater efficiency and flexibility – giving your crews faster, more accurate updates and easier access to the information they need.

ADP can be individually licensed, installed, used and updated. What’s more, your bridge crews can make one working copy of each licensed application per vessel. This means you can use the applications on two separate computers onboard while satisfying SOLAS requirements.

Helping prepare for digital navigation
Capitalising on the UKHO’s expertise, the ADP portfolio helps your crews to transition from paper-based nautical products to improved electronic alternatives.

Compliance
Approved by the flag states of the majority of ships trading internationally, ADP applications provide the same level of compliance as traditional ADMIRALTY paper-based publications, for ships trading under these flag states. In this way, ADP helps crews to navigate safely, efficiently and compliantly.

Check the UKHO’s website, www.ukho.gov.uk,for the most up-to-date list of flag state approvals and conditions, or speak directly with your ships’ flag authority.

Quality-assured information you can trust
Produced by world experts in maritime navigation information, the ADP portfolio has been designed to meet high navigational standards, as well as UKHO’s own internal quality assurance processes.

Fast and efficient updates
Quick, electronic updating reduces time and effort spent making manual corrections, and minimizes the risk of human error.

Global coverage – more routes and ports
All ADP products provide global coverage, divided into regions to provide flexibility and simplicity.
