Repairs are underway to the East Pier that was damaged in March's Storm Emma. The extent of the damage is visible from this landward photograph that reveals a breach in the harbour wall close to the bandstand area.

There was 'substantial damage' to Dun Laoghaire's East Pier following Storm Emma. 

Dublin harbours bore the brunt of the easterly storm when high seas caused flooding and infrastructural damage with the damage to the country's largest man made harbour revealed in these pictures here.

The bad news for the harbour, following its bicentenary year, came as Dun Laoghaire-Rathdown County Council recommended the dissolution of Dun Laoghaire Harbour Company and the transfer of its assets to the local authority that has since been completed.

At the end of this month the M.I.I. will celebrate the 70th anniversary of its foundation and it is the intention of the voluntary run museum to 'officially' re-open in March 2012.

According to the vessels survey schedules, RV Celtic Explorer had today completed fisheries demersal surveys which started in Galway on 23 September. The near fortnight-long survey was conducted in the ICES area VI, under the direction of chief scientist, Dave Stokes.

On Friday she embarks on a herring acoustic survey which is to take place in the Celtic Sea and the south-west. This survey will be under chief scientist Ciaran O'Donnell and is to de-mobilise in Cork on 27 October. To read more about her 2011 survey programme click HERE.

Across Dublin Bay in neighbouring Dun Laoghaire, the 31m RV Celtic Voyager is currently nearing the end of a month-long hydrography survey of the Celtic Sea. The survey had started in Howth Harbour on 17 September under chief scientist Kevin Sheehan. For the time-being she remains moored in Dun Laoghaire prior to resuming survey work which will continue until the vessel de-mobilises in Rosslare in mid-October. To find out more about her remaining surveys for this year click HERE.

On the surveys outlined they are conducted on behalf of Marine Institute scientists, though the vessels are also allocated ship-time for use of third parties. These include government departments and agencies, universities, research institutes and industry.

The 447 tonnes OPV provides communication liaison and assistance should the forty six sailors require during the arduous race including SAR. As such the vessel can deploy a rapid response high speed RIB-craft from an internal dock-well located at the stern.

Otherwise the RIB is used to board fishing vessels as part of fishery monitoring duties and patrolling France's Exclusive Economic Zone out to 200 nautical miles (370 km). She is a Flamant class OPV and was built in 1997 by the Cherbourg based shipyard Constructions Mécaniques de Normandie. The 54m/177-ft craft is equipped with two 12.7mm machine guns.

As Dun Laoghaire is the only international port of call during the four-leg stages of the 1,695 nautical miles (3,390kms) the hosting of the Irish harbour is a welcomed boost to the sailing community and the local economy. Leading off the Carlisle Pier are pontoons where the one-design boats are moored and opposite is the East Pier jetty berth where the PSP Cormoran is docked.

Also at the East Pier is a festival market which is part of the Festival des Bateaux. The three-day festival ends tomorrow and was organised by the race-hosts the National Yacht Club, the Dun Laoghaire Harbour Company and Dun Laoghaire Rathdown County Council.

The presence of a foreign naval visitor to the harbour was more commonplace particularly during festivals held in the 1980's. In addition to the French, navies from Belgium, The Netherlands were regular festival participants.
