Elements and Performance Criteria

1. Information received by weather fax is interpreted and recorded
2. Weather reports are obtained, interpreted and recorded
3. Observations of weather and cloud formations are made, interpreted and recorded
4. Statistical data and observations are used to predict likely weather conditions for a determined period
5. Use information to predict oceanographic conditions
   • Information on ocean current systems is interpreted and recorded
6. Nautical publications on tides and currents are used to calculate tidal conditions
7. Wave height and swell forecast is made using available information
8. Potentially dangerous oceanographic conditions are identified and appropriate actions are taken to maintain safety of navigation and to minimise risk to safety of vessel
9. Maintain records of weather and oceanographic information and forecasts
   • Statistical data and observations are recorded and filed according to organisational procedures
10. Actions taken to maintain safety of navigation and to minimise risk to safety of vessel as a result of weather and oceanographic forecasts, are documented according to organisational procedures
11. Meteorological and nautical publications are updated and stored according to organisational procedures

Range Statement

Range is restricted to essential operating conditions and any other variables essential to the work environment.
