I wanted to wait for the weekend, since this is long.

Hawaii gets its oil from Chevron and Tesoro, via tankers that offload through submerged pipes extending almost 2 miles from shore. Tesoro has 3 pipes, Chevron has 1 or 2. Each pipe carries a different product (crude, diesel, gasoline, etc.). These moorings are very expensive to maintain. When a vessel is on the mooring, it has to be attended by tug boats and booms have to be deployed and monitored. The mooring consists of numerous valves and hoses that connect to a manifold 100 feet deep and have to be maintained in top working condition (the ocean is a hostile environment).

One of the tankers that has brought oil to Hawaii is the "Frontline Suezmax Front Sunda". It is about 890 feet long, has a draft of 55 feet, and a capacity of 150,000 DWT. It offloads from the offshore mooring. Hawaii does not have harbor facilities for ships this big. Such facilities are rare in the Caribbean.

By comparison, the American Corvel I is 200 feet long with a capacity of 1,250 DWT. It can navigate the smaller harbors and offload more efficiently, in a less hostile environment.

It isn't economical for small island nations to install pipes for offloading oil, so the ships have to fit in the harbors. Thus the benefit to shipping with this vessel: it is more economical than barges heading to the Caribbean.

I hope this isn't too much information!
