You are so full of it. The "company testing" is being done at the command of the EPA. And the idea that a thousand foot long ship designed to suck up a half-million gallons of spilled oil a day hasn't been thought through thoroughly by engineers, is absurd.
"Sheen areas"? "Tar mats"? "Nearly impossible to skim"? Your terms are as bogus as your implied experience and knowledge.
"A craft like this"? Biggest lie of all - "a craft like this" is DESIGNED for a problem LIKE THIS.
Go back to your government bunker and get more training.
Yes sir, I'll be sure to do that. Meanwhile, you might want to just do a google search of Bob Grantham, the company spokeshole, who stated that testing was required to configure the ship. It's only repeated on virtually every newswire. As for the rest, I defer to your considerable expertise and remain appropriately chastised.
