After reading many reports, do they say why the ship rolled? As I read
it......

The cranes are hooked to the load and ballast(water?) is pumped into the
offshore ballast tanks to offset the off-center weight being lifted from the
dock.

Then the load is lifted to the center of the boat. At this time the ship
began to roll away from the dock.

An interview with a loading specialist said that the ship should have
re-ballasted as the load was swung onboard. This could have been
accomplished by pumping out the offshore tanks and/or filling the inshore
tanks.

There was some mention of a crane failure?
