Navigation Protection Piles

[Myoho]

Hi Im designing some navigation piles (free ended single laterally loaded piles) to protect a water inlet structure for a water treatment works. The inlet is constructed on the River Walton (UK). I need to know the magnitude of force that the navigation piles will be subject from a stray boat or maybe floating debris, logs etc. I have no marine knowledge as I am a geotechnical engineer. Any advice would be most appreciated.

you are designing a dolphin and should be given the ship size and speed that should be taken into account. If the Owner doesn't know refer to local waterways authorities.

Hi Ive got the ship size and speed. 100 tonnes at 2.5 meters/second. However Im not quite sure to convert that into kN. Any ideas please.

Check my responses in the geotech forum. -- BOTH of 'em. Trust me, you don't want to stop after the first.
