- Offshore Observer Training (CAP 437)


We are continuing to fine-tune the information we receive and combining it with other hydrodynamics and power management data to even better predict vessel movement. Supporting helicopter logistics is also an option as well. What is clear to us so far, however, is that the forecasting system provides significant potential for operators.

CAP 437 Meteorological Observer CourseOverview

The course objective will be to ensure that Met Observers will be capable of providing both a pre-flight weather report issued before Take-off, and on request, a radio message detailing the current weather on the helideck.

The training consists of a 2 day course. The detailed course timetable is shown here.

Training will be provided to ensure the specified information is provided in these reports using the correct terminology and reporting increments.

Information from automated sensors will be used to compile the weather reports. Training will be carried out to enable the Met Observer to visually evaluate the visibility, present weather, cloud amounts, height of cloud bases, and presence of significant convective clouds (TCU and CB). Trainee Met Observers will be provided with information detailing the limitations of automated weather observations that are used for meteorological observations; this will include understanding the limitations of using automated weather observations that may have been made within a 10 mile radius and the importance of ensuring the local conditions are accurately being reported.

Tuition will be provided to assist Met Observers in providing reports from contingency Met observing equipment which require the manual measurement of pressure, air and dew point temperatures, wind speed and direction. The reporting increments, terminology and other policies relating to the reporting of weather conditions from offshore structures will be aligned with the METAR code as detailed in CAP 746 Meteorological Observations at Aerodromes (Chapter 4 METAR structure and UK coding rules).
