When I first started working in the Industry in 1984, I worked with 2 Gulf Oil skippers who lost their ships when the Colonial pipeline came into being. At one time, there were dozens US flag tankers running crude and products from the Gulf to NY Harbor. Then there were none.
The Colonial pipeline may be maxed out now but it won’t be for long. Unless Trump overturns pending mandated Vehicle MPG improvements, oil demand on the USEC will continue to fall. Most Eastern states also want to ban the use of HFO for building heat. If a Democrat gets elected, expect a carbon tax which will accelerate the decline in consumption (which is already happening).
Long story short, you may get a couple of years to use a tanker but sooner rather than later that pipeline will be able to carry all of the Northeasts needs. It will economically crush any water borne transport of petroleum from the Gulf to NY Harbor. Just like it did in the 70’s. And you will have opened pandora’s box and wiped out tug and barge construction in the US to get it.
