A French munitions ship and a Norwegian steamer collided in Halifax harbour in December 1917, and the blast that followed remains the largest human-made explosion before the atomic bomb. Within six days, a formal inquiry opened — and within two months it placed nearly all the blame on one harbour pilot. Wreck Commissioner Arthur Drysdale's inquiry found Mont-Blanc's pilot and captain responsible for the collision that triggered the disaster, and all three men involved, including a naval...
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.
This video complements the earlier demonstration of wind effect on straight track and shows now wind effect on turning circles. It can be seen that during a turn under strong wind the ship reduces turning when it comes close to equilibrium on straight track - if the Wind-to-ship speed ratio is big enough then the ship even goes straight instead of turning. This is shown for three samples for Head, Stern wind and Beam wind. The turning can be increased if the ratio of Wind speed-to-ship...
