Greater efficiency, faster updating and more flexible information access – helping busy bridge crews to make quicker, more informed decisions ADMIRALTY Digital Radio Signals Volume 6 – essential maritime radio communications information for 3,600 service locations worldwide ADMIRALTY TotalTide – the world’s most comprehensive, real-time tidal prediction program, bringing global tidal height and stream data together ADMIRALTY Digital List of Lights – the world-leading source of navigational light and fog signal information If your crews use ATT to meet carriage requirements for tidal references, they must have the latest database version.Ĭrews can calculate and view safe clearances based on a ship’s draft, masthead and under-keel clearance allowance.ĭeparture and arrival-time planning is simplified, with prediction results displayed in user-friendly graphical forms.Ĭrews can make tidal height predictions for ports tidal stream stations around the world.īringing simplicity, flexibility and speed to passage planning and navigation The UKHO database of over one million tidal constants is updated on an annual basis in line with the ADMIRALTY Tide Tables. Maximise situational awareness through real-time tidal predictions, which can be overlaid on your crew’s chart-based display and updated every 60 seconds.ĪTT is widely accepted as meeting SOLAS carriage requirements for height, time and tidal streams worldwide, meaning ongoing safety and compliance. 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.ĪTT enables your crew to select and calculate tidal heights for multiple ports for up to 7 consecutive days. 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. ATT helps crews take full advantage of favorable tides – allowing them to calculate safe clearance and making departure and arrival planning easier.
