If all this is old news i apologise:
Two years ago three large oil refineries on the Delaware River were looking to close if no byers were found and the Aker Shipyard had no new shipbuilding contracts after 2013. But now all three have been bought and repurposed in some cases related to all the natural gas being produced in PA and the Mid West. The Aker Shipyard has a contract for four new tankers and four more on top of that based on future LNG needs.

You might know that Philadelphia has been a center for shipbuilding from 1690s to 1970 when I think the last ship was built at the Navy Yard. I might be wrong on the 1970 date. Anyway I am happy to see a rebirth in the industrial infastructure on the Deleware River as well as all the new businesses at the Navy Yard.
There is a documented walking tour of the Navy Yard at the link below, it looks very interesting.
