#navalvisitors - One of the world's most sophisticated submarines and an accompanying support ship of the Royal Netherlands Navy arrived in Dublin Port yesterday for a three day crew rest and recreation visit, writes Jehan Ashmore.

This is not the first Dutch Navy visitor to the capital this year as HNLMS Van Speijk, a Karel Doorman-class frigate was part of a three EU member state flotilla that called last month.

On this current visit, the first to arrive in Dublin Bay was submarine HNLMS Zeeleeuw, which has a 2,650 tonnes displacement (when submerged). In advance of entering the port a tug along with a small craft assisted the diesel-electric powered submarine while off the South Burford Bouy.

HNLMS Zeeleeuw was commissioned in 1990 however the submarine unintentionally became the first of the 'Walrus' class as HNLMS Walrus was delayed for a long period following a serious fire during construction. The 68m submarine was built by Rotterdamsche Droogdok Maatschappij.

The Walrus class instead of using a cross-shaped assembly of stern diving planes and rudders, they mount four combined rudders and diving planes in an "X" tail configuration (as more clearly demonstated in related story photo).

In total there are four submarines in the class and the quartet play a pivotal role in operations given these submarines have stealth designed technology. Deployments include overseas patrols in the Caribbean Sea with calls to Williamstad, the capital of the Netherlands Antilles.

The second visitor to Dublin is HNLMS Mercuur, which is the only surface vessel designed specifically to support the operations of the Dutch Navy. The 64m vessel was built by Damen Schelde Naval Shipbuilding and entered service in 1987.

Both naval visitors are berthed downriver in the main part of the port having been allocated berths at Ocean Pier within Alexandra Basin. They will not be open to public tours.

The pair are scheduled to depart on Friday with an hour appart of each other exiting the port in the morning.

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!
