A revolutionary newbuild multi-purpose cargo vessel, E-Ship 1, docked at Dublin port for the first time today writes Jehan Ashmore. The vessel had arrived from Emden, Germany with a cargo of wind-turbines bound for a project in Leinster.

At both the fore and aft of the new vessel stands a pair of giant metal circular towers which gives the ship a highly distinctive profile. Each of the four rotor tower "sails" are 25 metres high and four metres wide and these towers are driven by electro-motors which together with the wind harness wind energy to provide thrust for the 12,810 gross tonnes vessel. The ship does retain a conventional engine plant below deck and a streamlined superstructure and sleek hull to
reduce drag.

With all these innovative features, E-Ship 1 derives its project name from the enviromental ethos of her owners, Enercon, one of the leading manufacturers of wind-turbine technolgy. The newbuild is also termed the "Turbo-Sail Freighter" which apart from using wind energy to cut down fuel costs and measures to reduce emissions, there is also a double hull to lessen pollution from oil pollution incidents.

The origins for the concept of the E-Ship 1 is not new. In 1852 the Magnus Effect was invented and is named after the works of German physicist, Heinrich Gustav Magnus. The Magnus effect is a force acting on a spinning body in a moving airstream, which acts perpendicularly to the direction of the airstream; in essence when applied to ships, propels the vessel forward.

Another, German, the engineer, Anton Flettner adapted the concept in 1925 with the first rotor vessel, Buckau, a former schooner that was refitted with rotors driven by an electric propulsion system. On several North Sea voyages, the rotors performed well, despite stormy seas, though the technology was not deemed successful enough as the conventional engines were still more efficient and with the low fuel costs remained cheaper to operate.

With the threat of global warming, times have changed dramatically and the need for the concept of the Flettner's rotor-sailing ship has come full-circle with the launch of E-Ship 1 in 2008. Using the latest technology developed for E-Ship 1, Enercon carried out extensive sea-trials last year and first sailed commercially this year.

E-Ship 1 was firstly built at the German shipbuilder Lindenau-Werft, but the yard was declared insolvency. This led to the newbuild to be towed in January 2009 to and completed by the Cassens Werft in Emden.

Enercon was founded in 1984 and has since installed over 16,000 wind turbines in over 30 countries. The specially designed ship will be able to continue transporting wind turbines and components worldwide in addition to heavy lift-cargoes, containers and dry cargoes. The E Ship 1 is due to depart Dublin on Wednesday.

Ferry & Car Ferry News The ferry industry on the Irish Sea, is just like any other sector of the shipping industry, in that it is made up of a myriad of ship operators, owners, managers, charterers all contributing to providing a network of routes carried out by a variety of ships designed for different albeit similar purposes.

All this ferry activity involves conventional ferry tonnage, 'ro-pax', where the vessel's primary design is to carry more freight capacity rather than passengers. This is in some cases though, is in complete variance to the fast ferry craft where they carry many more passengers and charging a premium.

In reporting the ferry scene, we examine the constantly changing trends of this sector, as rival ferry operators are competing in an intensive environment, battling out for market share following the fallout of the economic crisis. All this has consequences some immediately felt, while at times, the effects can be drawn out over time, leading to the expense of others, through reduced competition or takeover or even face complete removal from the marketplace, as witnessed in recent years.

Arising from these challenging times, there are of course winners and losers, as exemplified in the trend to run high-speed ferry craft only during the peak-season summer months and on shorter distance routes. In addition, where fastcraft had once dominated the ferry scene, during the heady days from the mid-90's onwards, they have been replaced by recent newcomers in the form of the 'fast ferry' and with increased levels of luxury, yet seeming to form as a cost-effective alternative.

Irish Sea Ferry Routes

Irrespective of the type of vessel deployed on Irish Sea routes (between 2-9 hours), it is the ferry companies that keep the wheels of industry moving as freight vehicles literally (roll-on and roll-off) ships coupled with motoring tourists and the humble 'foot' passenger transported 363 days a year.

As such the exclusive freight-only operators provide important trading routes between Ireland and the UK, where the freight haulage customer is 'king' to generating year-round revenue to the ferry operator. However, custom built tonnage entering service in recent years has exceeded the level of capacity of the Irish Sea in certain quarters of the freight market.

A prime example of the necessity for trade in which we consumers often expect daily, though arguably question how it reached our shores, is the delivery of just in time perishable products to fill our supermarket shelves.

A visual manifestation of this is the arrival every morning and evening into our main ports, where a combination of ferries, ro-pax vessels and fast-craft all descend at the same time. In essence this a marine version to our road-based rush hour traffic going in and out along the commuter belts.

Across the Celtic Sea, the ferry scene coverage is also about those overnight direct ferry routes from Ireland connecting the north-western French ports in Brittany and Normandy.

Due to the seasonality of these routes to Europe, the ferry scene may be in the majority running between February to November, however by no means does this lessen operator competition.

Noting there have been plans over the years to run a direct Irish –Iberian ferry service, which would open up existing and develop new freight markets. Should a direct service open, it would bring new opportunities also for holidaymakers, where Spain is the most visited country in the EU visited by Irish holidaymakers ... heading for the sun!
