The means that us pilots must continue with our duties despite the risks involved with all the ships' crews arriving from different countries. So we need to take all safety measures possible.
This particular maneuver was unberthing a chemical tanker, in loaded...
How to get information for wind & current limits to be potentially encountered by thrusters – or current? - this will be described in this movie:
- Measure Drift speed, due to beam wind with no propulsion;
- Measure drift speed using full thrusters
- Estimate wind & current limits to be potentially encountered by thrusters – or current...
- Finally there is a simple formula as Rule of Thumb: the transverse drift speed is about 7-8% of wind speed!
