safety of the whole traffic system in consideration. The safety metric in DYNASIM© is a combination of the distance between the ships and CPA metrics. An example is illustrated in Figure 3. A prescheduled harbor traffic configuration is considered under various wind conditions, two nominal wind speeds (5 and 10 knots) and two wind directions (135º and 270º from the east). The wind speed is set to the nominal wind speed in the open area and is less than the nominal wind speedin the protected harbor areas. Figure 3 shows a view of the simulation environment under the 5 knots nominal wind and a direction of 270º (south to north). DYNASIM can also simulate ship traffic subjected to combined environmental conditions. Environmental factors affect the potential for accidents substantially. DY- NASIM can quantify the likelihood of collision depending on vessel hydrodynam- ics, traffic density, navigation channels geometries, and environmental conditions. Using this simulation tool, harbor designers and port managers can evaluate new wa- terway designs, modifications (e.g. ship size, characteristics, harbor obstacles, ship schedule, etc.), implementation of safety measures under simulated traffic and weather conditions. This simulator can be useful also for maneuvering training, har- bor traffic planning, and waterway management. http://www.dynaflow-inc.com/Products/Software/DynaSIM/DynaSIM.htm June 2012www.marinelink.com 29Figure 3 Comparison of the overall safety factor of the harbor traffic as a function of time for various wind speeds and directions. Reederei Claus-Peter Offen Selects ABS Nautical SystemsABS Nautical Systems announced the im-plementation of its NS5 Enterprise software suite has begun on Reederei Claus-Peter Offen?s fleet of container vessels. Based in Hamburg and one of the world?s largest sup- pliers of modern container tonnage, the com-pany will be using three modules from ABS Nautical Systems? integrated software solu- tion. Reederei Claus-Peter Offen purchased the Maintenance & Repair, Purchasing & In- ventory and Voyage Management modules for its fleet of 103 vessels. These mod- ules provide the tools to track maintenance expenses, upcoming drydocks and repairs, inventory replacement needs, fuel consumption and cargo operations across their entire fleet. ?We needed technology that offered both a centralized and standardized solution, and was user-friendly,? said Lutz Miesen, Project Engineer for Reederei Claus- Peter Offen. ?Our engineers and crew wanted a one-for-all solution for their day- to-day workloads and ABS Nautical Systems? software suite has provided that.?
