Transportation and installation of offshore rig legs

Weight: 240T, Length: 72m, Width: 2.5m

Project scope

Four offshore leg structures had to be transported from their fabrication yard within a short time period to the port where they had to be installed on to the rig. The main challenge here was to transport the abnormally long rig legs through narrow bending roads full of unavoidable obstacles.

Solution provided

We used 2 file wide, 18 axle Goldhofer conventional multi-axle trailers configured with turntable bolster attachments for the transportation. Upon reaching the destination the legs were top and tailed upright using our Liebherr 600T crawler crane as the main crane and our 250T Kobelco crawler crane as a tailing crane completing a successful transport and installation within a record time.
