I have just come across a website collated by John Bage at: http://www.bagejohn.webspace.virginmedia.com/index.html
There are links to NE shipyards and ports although you need to explore within the various links to find the sections dealing with the Tees up to Blyth.
The detail seems quite extensive. Compiled from various current websites and historic written material by the look of it.
