Research on hydrodynamic interaction indicates that if the speed of the ship near a bank is too high, the rudder may be less able to cope with the forces induced and control will be lost. The Nautical Institute highlights this in its latest Mars Report, in which an LPG carrier hit a barge being towed by a tugboat as a result of hydrodynamic forces.
I decided to show the typical happenings when a saltwater freighter arrives Duluth. Most of the time they go to anchor and wait for the Elevator dock. The Pilot Boat brings out the Great Lakes Pilot to sail the ship into the port and to the dock. This vessel arrived early Sunday morning, went to anchor until mid afternoon. They are loading grain at the CHS Elevator in Superor.
Practical samples for manoeuvres for ships going astern - as Stern-First-Method SFM. Introduction using as sample from the Master Thesis by Karel Wiegert for an arrival manoeuvre of a cruise vessel in Southampton port with a Twin-screw vessel under strong current. The same manoeuvre with the same ship model was used to show the advantage of Fast Time Simulation FTS using the SAMMON Planning Tool. This goes much faster than the manoeuvres in the real time simulator - and it can even be...
