ships in port use an oil "donut" to pump bilges into so they don't end up with an oil spil. This allows the oil to get deep enough to be pumped into a collector ship. If BP could get "floating dry dock" on site,flood it down, pump oil/water into it---the oil floats to the top and the water is pushed out the bottom. The oil can be pumped out into tankers. This may sound outrages, but IT WILL WORK.
