Hi Buggar, I know the lowering speed (0.2 - 0.5 m/s) but I do not know the deflection. Can I somehow estimate the impact force ignoring the deflection?
I am not a structural engineer and I have only limited information.
1. The problem statement, all variables and given/known data
An offshore crane is lowering a load with a constant speed of 0.2 m/s. The crane tip has a maximum vertical and horizontal acceleration, as a result of a seastate, of 2.0 m/s2 (vertical) and 0.8 m/s2. The crane needs to lower a 200 ton...
