400 tons on the water

A bridge takes to the water

Water and land route of reactor transport needs to be planned precisly in adventage.

We already have been able to successfully carry out orders for the company Ineos several times. This time our mission included the transport of a 300 tons reactor with a dimension of 23 meters  length, 3,85 meters width and a highness of 3,50 to take over at the port of Rotterdam. It had to be placed on a prepared foundation at Cologne Worringen. As usual as this job appears it wasn’t ordinary. It took two years of project planning and engineering work in advance.  

Our Team constructed the 2 x 14 axis SPMT modules according PMU aggregates in Dortrecht on a pontoon of Family Muller, ready for use. On the waterway it went now to Rotterdam. Two floating cranes performed the tandem lifting of the reactor onto the safely standing SPMTs. After proper cargo securing, the journey began up the river to Cologne Langel. A berth seemed well suited for the delivery, even if the massive difference in height had to be covered. So that the SPMTs could descend safely from the pontoon. Exact planning and teamwork among all participants was also required. When driving down from the pontoon, our team had to precisely tune the yielding of the pontoon bridge including the crossing bridge by pumping the ballast water out to prevent the bridge from sinking towards the shore.

 The 400 t heavy transport unit had to wait until further transport the following night and, as so often during these missions, was inspected by many transport fans. Our team had a short break after the usual clean-up work, as all preparations had already been made on the 8 km long transport route to Cologne-Worringen. Traffic islands had been built over and lots of roundabouts had been designed with metal sheets to absorb the enormous pressure of the transport unit. The road transport began at midnight and was completely secured and escorted by the police. The convoy moved to the chemical plant in Cologne-Worringen, where signs and traffic lights had to be reassembled repeatedly in order to provide the transport colossus with the necessary space. One of the most critical situations was crossing a bridge. Static investigations had to be carried out in advance and any changes in the statics had to be constantly monitored during the night. Everything went smoothly. Around 2:30 a.m., the SPMT transport with SPMT leader Thilo Fischer was able to drive through the main gate of Ineos in one piece and park  on a prepared intermediate storage site.

In order to lift the reactor in the final step, a PC 6800 platform crane was supported precisely on prepared bored piles. This measure was necessary because underground pipelines ran in the crane site area. These would not have been able to withstand the large support loads and could possibly have been damaged if the reactor had been lifted over pipe bridges. After this last challenge had been taken, the entire team was able to look forward to another successful assignment.
