The design of this rather strange load was partially brought about due to the layout of the site in Norway, and the installation procedure.

The Hot Oil Heater, with a length of width of approximately 13 metres, but with a height of over 24 metres and weighing in at 197 tonnes, is basically a tall column with peripheral equipment fore & aft. As the load could not be installed by a mobile crane and had to be placed by transport equipment, the design team came up with the idea of a transport frame which allowed trailer support at either side of the load; albeit nearly 9 metres apart.

If the move at the fabricators' had been just straight & level, there would have been no problem. However, although the assembly area was only half a mile from the quay edge, there were four 90 degree turns, plus a 2 degree slops to contend with.

In total, it took just under 3 hours to make the journey, constantly trimming and adjusting both trailer in all three planes. Finally seating the assembly onto pre-prepared shims set on the quay to within 10mm on the first attempt!
