I have just enough nautical knowledge to seem stupid on the Internet... My theory is that they were planning to neatly cut it into medium sized chunks that could be reasonably lifted out of the river with a medium sized crane on a flat barge and carried away. Severing the whole thing and dropping it into the river in one piece would require a significantly larger/more expensive crane and corresponding barge.
Not enough explosives at the severing points, or an underestimate of the strength/grade of the steel?
