Blackal is correct, I am pretty sure that it is Verolmes shipyard in Rotterdam. The Pterodactyl (?) type cranes are in use there and Sedco rigs used it for docking, one in the photo, and it was the only dry dock in Europe we could fit into. There was also a tank farm of some sort across a small channel at the end of the dry dock so think it has to be Rotterdam.
The Pterodactyl cranes caused lots of problems for our american hands. They are level luffing cranes which our americans could not figure out. Hand signals just did not work with them due to very different signals. Couple of times I had to point out that there were Dutch banksmen there with radios to talk to the driver. Easy once you knew that.
