We often talk about labor constraints, but there are many infrastructure bottlenecks, such as in this email the last year – the aging locks on the inland waterways or pipelines under capacity.  A constraint just surfaced – very large crude carriers (VLCC) can’t get into Gulf ports.  We have to use smaller, less efficient ships.  To overcome this problem, three U.S. energy logistics firms – Buckeye Partners, Phillips 66 Partners, and refiner Andeavor – formed a joint venture to build a terminal for handling VLCCs at the port of Corpus Christi.
