As part of an industrial project for the American Patriot Holdings LLC (APH) dealing with a new concept of an inland waterways container carrier (designed by NaviForm Consulting & Research), outdoor manoeuvring tests were conducted to complement the standard resistance and propulsion tests.<\/p>\n

The manoeuvring tests were performed in a sheltered little bay of the Berlin part of the river Havel in the city of Spandau. The approximately 9 m long ship model (scale: 20) was manufactured at SVA Potsdam and, in accordance to NaviForm specifications, equipped with modelled superstructures and stylized containers. The ship was propelled by 4 VSPs, of which 2 were used solely for propulsion and the others mainly for manoeuvring purposes. The drives were provided by Voith Turbo GmbH & Co. KG. In the manoeuvring tests straight line, turning on the dime, turning circle and dock moving sidewise tests were conducted.<\/p>\n

The tests were performed for a single draught. The thrust distribution scheme for the 4 drives which was identified as the best during previously conducted towing tank tests was also used in the outdoor tests. For full scale speeds of 8 kn and 12 kn straight line and turning circle manoeuvres were demonstrated.<\/p>\n

The model tests were documented with video recordings. Beside a stationary camera a quadrocopter drone was used that provided recordings from different views of the manoeuvring behaviour of the ship.<\/p>\n

The results showed that the targeted speed of 12 kn in straight line test could easily be achieved with the optimized thrust distribution scheme for the 4 VSPs. A turning circle with a diameter of less than 7 ship lengths can be achieved for a velocity of 8 kn and a thrust direction of 10\u00b0. At 12 kn the diameter of the turning circle spans about 7 ship lengths.<\/p>\n

Due to the utilization of a purpose built wing system at the ship\u2019s bow a considerably reduced wave system could be observed even at a speed of 12 kn.<\/p>\n

In general a very good manoeuvring performance could be demonstrated for this inland waterways container carrier.<\/p>\n
