The ship left port weighing 112,383 metric tons (ship+cargo). Travelling at it's loaded full speed of 16.8 knots, that comes out to be about 10.6 GigaJoulese or 3 Megawatt-hours of kinetic energy.
TNT has an energy density of about 4.2MJ/kg. So the kinetic energy of the Dali at full speed is equal to about 2.5 metric tons of TNT.
According to the report, the Dali was running at slow speed, which is 10 knots, giving "only" 0.7 tons worth of TNT in kinetic energy.
Granted, ships operate in a relatively low friction environment, so you do not need that much power to get it moving. However, modern shipping vessels are massive.
- smegsicle 2y agotnt is the more commonly used metric but to put it in more practical civilian terms that would be around a trunkload of anfo (might need to share the back seat but who uses all that legroom anyway)
