Feature 2 | PASSENGER AND FREIGHT FERRIES Navantia designs reign in Spain


Latest Acciona Trasmediterranea ferries meet the Spanish market requirements for fast and reliable vessels with a significant controlled temperature freight capacity. David Tinsley reports.

weekly rotation on the 1500 nautical mile route, or to perform two weekly round-trips on crossings of 700-800 nautical miles. With a multi-engine propulsion plant


conferring the requisite 26knots at 90% maximum continuous power output, Jose Maria Entrecanales offers considerable scope as to both the extent and nature of the itineraries which she can serve, while also giving added flexibility in responding to changing and varied service demands. In this respect, the importance of the


northbound trade in fresh produce, and the design’s substantial provision for carrying temperature-controlled goods, has a signal bearing on transit time performance, and the need to be able to adjust to market demands at any one time. Te hull form and dimensioning reflects


not only the requirement for a fast service speed, but also for sea-keeping performance and year-round scheduling reliability on the route along the western fringe of the Atlantic. Two sisterships were ordered by Acciona


Trasmediterranea from Navantia Astillero San Fernando-Puerto Real, whose large-scale yard is located on the Bay of Cadiz. Te second vessel of the class, Superfast Baleares, was handed over in mid-year. The circa €200 million investment encapsulated by the two vessels, and the key


characteristics relating to freight capacity and speed, have been shaped not simply by the Acciona group’s role as a shipping service provider, being one of Europe’s largest ferry companies, but also by its stake in through transport operations. Acciona Logistic controls a fleet of 900 reefer trailers plus 1500 dry cargo trailers, which load on to the Acciona Trasmediterranea ferries. The logistics network also includes over 100,000m2


of warehousing, 150,000m2


of temperature-controlled storage and 600,000m2


of own dock area. Reflecting the group’s involvement in


door-to-door movements of perishables, the Jose Maria Entrecanales generation offers a very high reefer component within a freight capacity of 210 trailers of 31tonnes plus 50 double-stacked containers. The ro-ro intake corresponds to some 3500 lane-metres overall, with the four freight decks complemented by a dedicated, fixed car deck for about 100 units located above the main deck forward. Te 15m-wide stern ramp/door, which


has an overall length of 18.6m including the flaps, provides the sole ro-ro interface with the shore across the main deck threshold. Te bow is accordingly finer than would be the case with a drive-through layout, and the steep rake culminates in a surface- piercing bulb.
