Über 30 Jahre war das Panmax-Schiff das Rückgrat des weltweiten Container-Seetransports. Mit Stellplatzkapazitäten von maximal 5.000 TEU und Dienstgeschwindigkeiten von bis zu 25 kn waren sie zu ihrer Zeit das optimale Transportmittel für Containerfrachten.
For over 30 years, the Panmax containership was the backbone of worldwide container sea transport. With maximum capacities of 5,000 TEU and service speeds of up to 25 kn, they were the optimal means of transport at their time for container freight. It was not until the 1990s that they were gradually replaced by the wider Postpanmax ships. To prepare the exisiting Panmax units for the future, REEDEREI NSB offers an innovative widening concept. Three vessels managed by NSB have been widened in 2015 already and are successfully in service.

Am Heck kann dies nicht ebenso gewährleistet werden. Allerdings gehen wir davon aus, dass bei Geschwindigkeiten unter 20 kn der Einfluss einer idealen Form abnimmt. So beträgt bei einem Containerschiff der mittleren Größe bei 18 kn der Reibungswiderstand 67 %, der Wellenwiderstand 9 % und der Formwiderstand 24%.
We at REEDEREI NSB have developed an entirely different widening concept. The ship will be cut in the hold area at amidships, where the load is low at right angles to the cut and the steel is therefore comparatively thin. The necessary cuts at right angles to the ship are made at the engine room front bulkhead and at the collision bulkhead. Here the bending moments are much lower than at the main frame. The front part of the ship is lengthened by a hold so that the form remains. It is trickier aft. However, we assume that the influence of an ideal form declines with speeds below 20kn. Thus, for a containership of medium size at 18kn the friction resistance is 67%, the wave resistance 9% and the form resistance 24%. The bulbous bow – which has to be replaced by a new one because of the widening anyways – is optimised for reducing the wave resistance with the aid of CFD methods for speeds below 20kn.
