#GERMAN NAVY – Three German Navy vessels that forms a task force group docked in Dublin Port this morning for a weekend courtesy call, writes Jehan Ashmore.

Auxiliary tanker FGS Frankfurt Am Main (A1412) berthed in the heart of the port at Alexandra Quay West, close to the East-Link Toll-Lift Bridge. The 174m vessel which displaces over 20,000 tonnes will remain somewhat obscured from view during her port of call due to the surrounding dockland infrastructure.

The Berlin class replenishment vessel and her leadship sister FGS Berlin are the largest units in the German Navy. They not only carry fuel but also handle stores, military equipment, ammunition, medical services and can accommodate helicopters.

Footage above shows the task force departing Portsmouth from a vantage point taken from The Hard that leads into the Hampshire harbour.

Across Alexandra Basin lies the Sachsen class air-defence frigate FGS Hessen (F221) of 5,690 tonnes. The third member of the trio is the 130m Bremen class multi-purpose frigate FGS Emden (F210) of 3,680 tonnes which is moored at an adjacent berth alongside at Ocean Pier.

Unlike the auxiliary the frigates will be more visible from the south quays near the Poolbeg Yacht Boat Club marina at Ringsend.

# PORTS & SHIPPING -A specialist cable-laying vessel, Cable Innovator (1995/14,277 tonnes) arrived into Dublin Port yesterday. She is due start work next week on a €12.5m telecoms cable for CeltixConnect between Dublin and Holyhead.

According to a report in The Irish Times (click HERE) CeltixConnect's chief executive Diane Hodnett expected customers to start transmitting traffic on the cable at the end of January.

The cable will pass through the East Point Business Park in Dublin and on to the city's IFSC. On the Welsh side, the 131km cable will connect to the Welsh Assembly-funded Parc Cybi business park in Holyhead. From there it will connect to networks linking Manchester, London and the rest of Europe.

Capacity on the cable will be sold primarily to telecoms firms and ISPs, mobile phone operators and a small number of multinationals in the technology space which have massive bandwidth requirements.

For more information about the UK-flagged vessel which berthed in the port's Alexandra Basin, click this LINK.

She has a gross tonnage of 2,998 and a single-box hold with two portable bulkheads which can be placed into 10 positions for cargo separation. At 4,800 dwt, ship is certified for the carriage of dangerous goods of IMO Class 4.1, 4.2, 4.3, 5.1 and 5.2 (packaged) as well as general bulk cargoes. The main engine is a MAN 6L27/38 2040kW gearbox with CPP, delivering about 12 knots.

The 89m Arklow Forest was one of the 4,500 dwt 'R' class designs but was modified to allow carriage of a further 300 tonnes of cargo. She follows Arklow Field (PHOTO) which entered service this year and to read a report on another F class, Arklow Future click HERE.

Arklow Shipping Ltd with its headquarters in Co. Wicklow operate the fleet which in the majority are Irish registered. Some vessels though are managed through Dutch subsidiary Arklow Shipping Netherland B.V. based in Rotterdam where they are also registered in that port.

On board the open-topped yellow tour-boat RIB, an audio commentary firstly informs you about the M.V. Cill Airne, built nearby in the old Liffey Dockyard, nearly fifty year ago. Discover why she was one of the last riveted built vessels in Europe, her days as liner-tender and the rich and famous who threaded her decks.

Heading downstream the former lightship Kittiwake is berthed opposite the O2 Arena. She was one of the last lightships to serve in Irish waters at the South Rock station off Co. Down. In complete contrast a ferris-wheel revolves in the background but no sooner the boat slips under the East-Link Toll-Lift bridge which opened in 1984.

On the other side of the bridge a small non-descript looking grey-hulled motorboat lies at anchor, on her bow is painted the figure 11. So what's the story here!...here's a glue: 'Don't pay the ferry man until you get to the other side!...

Past Poolbeg Marina, giant blue-gantries cranes of the Marine Terminal Ltd (MTL) are busy unloading from Karin Schepers, a containership previously reported on Afloat.ie. Look out for the ports  'graffiti', the work of crews who make their mark by painting the name of their ship and also the mural of the late Ronnie Drew of The Dubliners.

Opposite this terminal is the ports largest basin, Alexandra Basin, named after Queen Alexandra. Subject to port security, the tour may include entering the basin should there be a particular vessel of note.This also allows for views of the dock-gates of the Dublin Graving Dock, one of only three large ship-repair facilities on the island of Ireland. Neighbouring the graving dock is where the Liffey Dockyard once stood.

Before the tour passes the towering twin stacks of the former ESB Poolbeg electricity power station is tucked away Pigeon Harbour. Learn more about its hotel conveniently sited beside where packet-ships regularly plied, essentially the ferryport of its day. Its modern-day counterpart faces opposite on the north quays where up to 17 sailings daily operate on the Irish Sea.

Marvel at the length of the impressive Great South Wall, why was it called 'Great' and why was it built?... What can be revealed is that Captain William Bligh of "Mutiny of the Bounty" fame was a major figure in the project, when the wall was completed in 1795.

The commentary has many more fascinating facts, figures and the occasional anecdote told with typical Dublin wit. So if you live within 80km (50-mile) radius of the capital, then the chances that the shirt you wear, the breakfast cereal you ate and the car you drive, most likely came through Dublin Port as almost 75% of goods serve this hinterland.
