Passage Planning Flashcards
What is APEM?
- A systematic process for creating a passage plan to ensure all eventualities you may encounter have been considered
- Appraisal, Planning, Execution, Monitoring
You are asked to plan a passage from Southampton to the Bahamas, take me through the Appraisal process?
- Get the passage planning checklist from the SMS to ensure nothing is missed.
Firstly
- NP131 Chart Catalogue
- overview of the route on large scale gnomonic charts - Gives rough distance of the passage
- Estimate DEP/ARR times
- Fuel or stores stop
- Time zone changes
- Once happy with the route I can transfer the passage to a Mercator chart, medium scale for ocean passages, small scale charts for port approaches/ pilotage
- Ensuring all charts and pub’s are up to date
- Ocean Passages of the World: for dist tables, recommended great circle routes, climatic charts for the extent of ice and wind conditions
Secondly
- Admiralty Sailing Directions for info on coastal passage at either end e.g. high traffic densities
- Total Tide for ports en route and destination
ALRS

What is the difference between VTS and VTIS?
VTIS - have the power to order the movement of ships and they must adhere (e.g. Southampton)
