Yes, if I anchored where I shouldn't have, I agree. But info I've heard (and I'll wait for the final word) is that the anchored position was legal, they were asked if they could move out of the way of this drifting barge, and couldn't:
Yeah, let's wait and see, but if they think this ship could've got underway or shifted position (in 14 minutes according to the above) during a storm so as to make this drifting barge miss this large ship, pleeeease give me a break. The pressure is on local authorities to throw the book at everyone whenever there's a spill.
Now South Korea is taking steps to ban single-skin tankers (which are being phased out anyway) from their waters. One would not expect them to place any blame on themselves.
Again, let's let it play out, but my view going in is that this is a heck of a way to end up with a criminal charge.
