The SIEMENS AG Power Generation in Erlangen (Germany) charged the International Project Forwarder Rolf Riedl GmbH in Hagen (Germany) with organising and realising the transportation of the heavy components for the third enlargement step of the thermoelectrical KW Ribatejo, Carregado, near the Tejo river (30 kilometers North-East from Lisboa).

Time of delivery: The middle of February till the middle of March 2005.

At different terms and by means of ship’s gear, a condenser 8500 x 4600 x 7160mm, (109.5 tons) with its oversized supplies in Banten/Indonesia, one Generator THRI 108/55, 11950 x 4600 x 4950mm (317 tons), one Steam Turbine E30-25-2-12, 9340 x 6160 x 6150mm (200 tons), as well as one Gas Turbine V94.3A, 10930 x 5180 x 4860mm (305.9 tons) in the North-Sea-Port and a BAT-Transformer 10950 x 3300 x 5050mm (315 tons) in Leixoes/Portugal were loaded onto 3 H/L vessels and shipped to the Port of Lisboa.

ODC’s like UBA-Containers, Oil-Modules, H-Part-Turbines, Stop Controls Valves, Exhaust Gas Diffusors, etc. were conveyed to the building site via roads.The heavy parts were positioned on a Ro/Ro-Pontoon lying alongside to a H/L vessel, on cross beams on stillages and set down on a self propelled transport unit (SPMT) on deck with the help of the
ship’s gear. Then the pontoon was hauled down the Tejo River to the modified roll-off-jetty, Carregado.

At the jetty, the pontoon ramp was laid out on a bed of load distribution steel sheets and wooden beams , employing a mobile crane. The components were unrolled by means of loading and trimming the pontoon and were intermediately stored right next to the railway on cross beams and stillages. Crossing the railway was only permissible between midnight and 5a.m. In this short time frame, we had to switch off the elctricity, lifting the catenary wire and build a pontoon bridge over the track using a 250 tons mobile crane. The heavy components were transported over the railway tracks into the power station, at three weekends. Afterwards the railway had to be fit for service again. The specialists from the Rolf Riedl GmbH manhandled this bottleneck without any time delay.

Generator, gas turbine, steam turbine and the ODC’s were unloaded by using the powerhouse crane and put on the foundation. Especially the 315 tons BAT-Transformator was put precisely (millimeter per millimeter) on the foundation and exactly in due time, by the Riedl & Tschierschke GmbH, a company from the Riedl Group.
