I can tell you that anything the EPA wants done is known before you even get possession of the ship, and preparing a ship for a reef is not rocket science, but requires dogged determination, because all the people in postitions of figuring out why you CANNOT do something show up.
Bigger vessels are always a bigger deal because of being high profile projects, and Reefmakers are the best at marketing I have ever seen (best name, bumper stickers, T-shirts, website is really good, heck, they even have a song), but I have always found that press attention brings out the bad with the good. I hate to say mismanangement, but when I was running the preparation of the Spiegel Grove (after the first guy, oceanreefs, david tomlinson, screwed the pooch) I was everywhere troubleshooting on the ship every day, and still have a mental image of the ship, every compartment, space, to the point that I am so intimately familiar with the ship that I can monito progress or the lack thereof.
