Port Ash Australia: Ship Handling Training & Research Centre
By A. Beazley, Port Ash, Australia
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!
Pilot cutters are used to take pilots between the three pilot stations (at Gravesend, Harwich and Ramsgate) and ships entering or leaving the Port of London.
Three dedicated pilot cutters Patrol, Guide and our hybrid Leader are based at Gravesend. The six cutters used at Ramsgate are operated by a Estuary Services Limited, which is jointly owned by the PLA and Medway Ports Ltd.
