HSB INTERNATIONAL JUNE 2007 - 7 of the overall operational costs.Therefore the performances of the push boats of ThyssenKrupp Veerhaven BV are monitored and tracked, using a sophisticated system “Tempomaat” installed by Techno Fysica.The resistance characteristics of the river from Rotterdam to Duisburg have been processed in a data base as well as the engine character- istics. Position and speed over ground input is carried out by a GPS. During the voyage the measured engine data are checked with the engine characteristics and the river charac- teristic. After departure the system is switched on, the computer now continuously calculates the optimum speed for a pre-set time of arrival and adjusts the throttles accordingly in order to optimise fuel con- sumption. This permits the officer of the watch to fully concentrate on navigation. If necessary for nautical reasons the system can manually be overruled. The system can be compared with a cruise control on cars, except that in this case the target speed is not set by the driver but calculated on arrival time and minimum fuel consumption. A visual display unit (VDU) provides the offi- To improve the view forward, the bridge windows are without mullions cer of the watch with up-to-date information on speed, main engine revolutions and fuel airconditioned.

The A lot of effort has been made to realise a Three MaK engines provide a total of 4.080 kW of propulsion power clear view over 360 degrees from the wheel- house. In order to obtain this, there is no steel construction at all in the wheelhouse front and rear, and only a minimum of steel construction in the sides.The frameless win- dows are made of double glass which is glued directly to the construction and to each other. The spacious wheelhouse contains a central command console which has been arranged for one-man watch operation of the vessel. In order to have an unobstructed view to the foredeck during manoeuvring and coupling of the barges, the two radar monitors are fitted on a separate swing arms, which can be shift- ed from the position in front of the central command console to the side on a rail system integrated in the command consoles. The vessel’s navigation and communication equipment is fitted in the central command console and in overhead displays. The com-
