An investigation into actual strength of ladders and intermediate securing methods used.
Capt. and Marine Pilot Troy Evans (New Zealand) decided to look into pilot ladder strength and intermediate securing arrangements after MNZ put out what he felt was a confusing and unclear document about securing of pilot ladders.
Another very good explanatory video by Knud Benedict. Absolutely worth seeing.
Yaw Stability is an important element of Ships Manoeuvrability - both for course keeping and turning ability. This first video in a series explains the Basic Principles of stability in steady state equilibrium conditions and the forces / moments involved
Here’s some cool video footage we captured of the Cork Pilots in their Interceptor 48 pilot boat ‘Failte’ undertaking pilot transfers off Cork Harbour during the recent days of strong SE gales. Roches Point lighthouse recorded 50kts of wind on the 13th as the Cosco bulk carrier passed and the Cork wave buoy 2nm off the harbour entrance recorded waves to 6.7m at the time. The pilot boat coxwain managed to get alongside and safely disembark the pilot despite the challenging sea state....
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.
