November 26 - Wagenborg has been contracted to transport two stators from the port of Rotterdam to the KEMA plant in Arnhem, the Netherlands, and install the equipment onto its foundations.

So far the first stator, which weighed 183 tonnes and measured 7.37 m x 3.87 m x 3.3 m, has been transported and installed at the site. Having been shipped to Rotterdam, the stator was lifted from the vessel onto an inland barge and transported downriver to Arnhem.

Upon arrival in Arnhem, a 400-tonne floating crane took care of unloading the cargo onto a modular trailer. In order to keep the floating crane in position, several winches and a tug boat were utilised.

The stator was then transported by road to the project area. Wagenborg explained that it had to construct a temporary bridge over an underground cable trench en route to the site, in order to avoid damaging it.

On arrival at the site, the modular trailer was lowered hydraulically and the stator was then positioned onto a skidding system and skidded onto its foundation, where it was connected to a hydraulic gantry system, then lifted and lowered into its final position.



Elsewhere, Wagenborg also completed the transportation of 21 prefabricated modules, weighing around 36 tonnes each, for a new pilot pyrolysis plant in Hengelo, the Netherlands.

The plant, which is expected to be ready by the end of 2014, will use the pyrolysis process to convert biomass into oil and gas. The generated gas will be used to create electricity and supply power to the adjacent salt plant of Azko Nobel.

The modules, each of which measured 12.5 m x 5.5 m x 7 m on average, were transported 15 km from the manufacturer's site in Enschede to Hengelo.

Due to the dimensions, the engineering and execution of the transport was a major challenge, said Wagenborg. With the help of several mobile cranes, the frames were first turned inside a hall at the manufacturer's site.

Some of the items also needed to be jacked up and skidded under a hatch in the roof, so that Wagenborg's new Demag AC 700 mobile crane could hoist the modules and load them onto low loaders and modular trailers for subsequent transport.

Each frame was moved by road to a nearby quayside, transhipped onto an inland vessel, and transported to a quayside and temporary storage area in Hengelo, close to the pyrolysis plant construction site.

After being placed on elephant feet, the units were transported to the site using one of Wagenborg's seven-axle hydraulic extendable semi-low loaders, which was equipped with extra 3.5 m wide support beams.

On arrival at the construction site, each frame was lifted by crane, and manoeuvred into the correct installation position with the help of a tailing crane.
