The recent posts on the American 11320's and the history of them in the big fabrication yards prompted me to post some of these pics collected from the net. These were all taken in the big "Highlands Fabricators" yards at Nigg Bay Scotland. This was a huge Brown&Root operation set up to build the first of the realy heavy steel offshore jackets in the North Sea. Most are pics of the fabrication of the "Highland Two" Jacket, about 1974. These were taken before the big Lampson Transi-Lifts were brought into the Yard. JRay McDermott also ran a massive yard at Ardersier Scotland "Ardersier Yard" with simialr equipment. Mcdermott ran mostly a fleet of Americans, and a huge Manitowoc 7000 and then got a couple Transi-Lifts also. Highlands Fabricators "Brown&Root" had a lot of Manitowoc's and a few American 11320 "Super Skyhorse" and two massive Clyde marine cranes that were modified into high level traveling gantry cranes, as I recall 700 ton and 400 ton cap?..........
