Dredger OCEANLINE 5001 sailing at full speed struck anchored tanker STROVOLOS with moored alongside supply vessel, at around 1140 LT (UTC +8) Oct 2, on Melaka anchorage, Malaysia, Malacca Strait. The results can be seen on video – tanker suffered portside hull breach above waterline and apparently, some damage on cargo deck.

When a pilot is berthing a ship with the aid of tugs, it sometimes happens that the ship lands heavily and suffers minor damage. More commonly in my experience, it also happens that the crew discover a large dent for which they cannot account ...
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!
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.
