Week 12 Challenge

GIVEN

SW = 52500 tonnes

No of containers = 4500

each container weights 6.1 tonnes

Load = 4500 x 6.1 = 27450 tonnes

TOTAL LOAD = 27450 + 52500 = 79950

Speed of Brage = 60kmph = 16.67 m/s

L = 294 m

draft = 12m

beam = 32m

Ch = hydro dynamic co-eff = 1.25

TO FIND BARGE IMPACT LOAD

Barge Collision energy, KE = 500 x Ch x W x `V^2` = 500 x 79950 x 1.25x 16.67 = `0.832812 xx 10^9` Nm

aB = 3100 [ (1+ `sqrt1.3xx10^-7 xxKE`)-1] = 32255.738 mm - barge blow depth

Pb = (6x10^6) + (1600xaB) = 57609.18135 kN- Barge collision impact load
