I mathed. I think the collision of the NV Dali with the Baltimore Key Bridge had the energy of about 1/5th of a ton of TNT.
kinetic energy = ½ m v ²
maximum mass of ship about 116,000 metric tonnes.
velocity was about 8 knots or about 4 m/s²
multiplying everything out means about 930 million joules.
I tried to think of a comparison, and one ton of dynamite is defined as 4.18 gigajoules.
930 million / 4.18giga is about .22, so with yet more rounding about one fifth (1/5).
Lots of rounding because who knows how loaded the ship was.
