The Nordenham site produces some of the largest elements of this type available on the global market.
The dimensions are truly remarkable: we are talking about a component with a diameter of 9.60 meters, a length of 110 meters and a weight of 2,100 tonnes – an absolute mega-monopile. And these giants are produced in batches at Steelwind.
Krebs is responsible for transport logistics at Steelwind
The Krebs company - 70 years in business and in its third generation - has now secured a major contract from Steelwind with a term of several years. The actual core competence of Krebs Korrosionsschutz (corrosion protection) kicks in here: the high-quality coating of pipes. On top of that, the specialists have also taken over the complete transport logistics in the factory.
"It is irrelevant whether the storage of steel plates, the movement of individual pipe sections or the transport of the complete monopiles is concerned", says Christian Petschke, one of Krebs' managing directors, describing the project from Hamburg. "We started right away with the removal of a finished monopile from storage in the external warehouse behind the dyke. We had to pick it up and then transport it over the dyke to the loading pier on the factory site at a time specified by the regulatory authority of the town of Nordenham."
With regard to the gradient and the timeframe
The challenge on this route is to overcome the dyke’s three-degree gradient with a gross vehicle weight of an impressive 2,450 tonnes and a vehicle length of 37 meters.
"The timeframe is critical", explains SPMT driver Steffen Klückmann, "because we will cross two public roads here that ensure the supply of goods by truck to the neighboring industry."
72 axle lines as a 6-file group
For this purpose Krebs coupled together a 24-axle Cometto SPMT combination to form a 6-file group using two 368 kW power packs and one 202 kW power pack. Two massive cross beams were installed on the combination comprising a total of 72 axle lines. This is done with the objective of evenly distributing the loads introduced among the three SPMT units.
A 12-axle combination moves the sleepers for the pipe depository and the small pipe sections in the factory, And this fleet of vehicles now has to operate in shifts. True to Krebs' company motto: modern, flexible and innovative – propelled to the MAX with Cometto!
