This photo was sent to me quite some years ago by Dennis Weller, son of Albert Weller whose photos I have featured extensively on NEM:
The location is clearly in Middlesbrough Dock Cut, with Dock Point in the background, the site of W Harkess & Son - Iron & Steel Shipbuilders as can be seen on the warehouses.
David Asprey provided me with details of her career:

What a fine view of the tug but also a nice link to Harkess and the shipbuilding industry. I had not realised they were so close to the Dock Point.
