This paper presents a methodology toaiming at improvinge the design of short sea shipping (SSS) services through the complete consideration ofembedded in intermodal door-to-door transport chains. The cargo capacity of a Ro-Ro ship for such a service is identifiedestimated. , when tThe ship is assumed to operates in an integrated in an intermodal transport network that comprisinges competing transport chains. The latter linking multiple origin-destination (O-D) pairs, in a set of discrete geographical regions separated by sea, including non-EU countries. The methodology comprises four steps, starting by estimating freight transport demand between O-D pairs using a method that combines international trade and maritime transport data. The estimated demand is then allocated to transport chains based on a logistic regression model that considers both cost and time of transportation. The maximum aggregate freight transportation demand among all legs of the Ro-Ro service is used as the governing criterion to determine the right ship size. An application of the methodology is carried out for the case of a Ro-Pax service between mainland Portugal, Madeira and Morocco, as a set of two round voyages with opposite rotations. The SSS service researched here is of particular interest as it could provide a crucial link, serving simultaneously an EU peripheral region and a fast-developing non-EU country. The required cargo capacity of the ship, expressed in lanemeter length, is determined, with results showing that the proposed adjustments can significantly improve the economic results of the service.
