The ten modules, weighing up to 350 tonnes each, then had to be lifted down into the 15 m deep test pool.
Nordic Crane Stangeland was involved in the project from an early stage and conducted a study to evaluate various alternative crane solutions for the installation of the components. The most cost-efficient solution for the customer was to lift the components in using a fully rigged Demag CC2800 crawler crane positioned on a solid concrete foundation next to the test pool.
The first load consisted of an 18 m wide module weighing 980 tonnes. After months of detailed planning of the transport route, which included mapping the clearances along the entire route, the large module was driven ashore from the barge down at the docks of the Ormen Lange plant and along the 2 km route through the plant. Once it arrived at the test pit, the module was carefully placed on the foundations at the edge of the test pit.
The transport of the modules in the test pit itself was performed in two sessions, roughly one month apart. At the test pit Nordic Crane Stangeland had rigged up a 600-ton crawler crane to lift the modules down into the pit.
