Since Tuesday the offshore patrol vessel (OPV) has been berthed in the Baltic city of St. Petersburg. Her naval officers laid a wreath at the Piskarevskoye Memorial Cemetery. Also visited was the Central Naval Museum and the naval cruiser Aurora, where one of the first incidents of the 'October' Russian revolution took place in 1917.

Irish Ambassador to Russia Philip McDonagh boarded the L.E. Roisin yesterday to highlight Irish-Russian bi-lateral relationships and co-operation between the two countries in areas of economic, culture, education and tourism. In the first-half of 2010 bi-lateral trade with Russia was up 66% and St. Petersburg is the most important economic centre after Moscow.

The trade mission follows last year's visit of president Mary McAleese who became the first Irish head of state to visit Russia. On her visit which included St. Petersburg, she signed a protocol on partnership and co-operation between the Russian city and Dublin during the third St. Petersburg International Innovation Forum.

In March of this year representatives from St. Petersburg took part in the Russian Culture Festival in Dublin. Three months later in July, the Irish capital was visited by the Russian Naval destroyer Admiral Chabanenko (650), the flagship of the countries Northern Fleet. For more on that visit of the Udaloy –II class destroyer click HERE.

L.E. Roisin is not the first Irish Naval Service vessel to visit the Russian Federation as this accolade goes to the flagship L.E. Eithne (P31) which called to St. Petersburg in 2003.

In March another foreign-flagged fishing vessel, the UK registered Lynn Marie was detained on the same grounds for an alleged breach of fishing regulations by the L.E. Orla (P41). The Lynn Marie was escorted by the Peacock –class coastal patrol vessel (CPV) into Dun Laoghaire Harbour and similarly the custody of the vessel was transferred to the Gardai.

So far this year the Naval Service has carried out 852 boarding's and eight detentions of vessels off the Irish coast. In 2010 the navy conducted 1666 boarding's which resulted in warnings to 70 vessels and eight detentions.

Those participating are asked to assemble at the Hibernia Inn (near Bray Dart Station) from 13.00 hours. At 14.00 hours, an anchor shaped wreath will lead the procession of wreaths to the north Bray pier-head where a memorial service will be held, at which representatives of those in attendance will be invited to speak.

This will be followed by one minute's silence after which, those accompanying the wreaths will embark on the flotilla to a position approximately five-cables due east of Bray Harbour.

Anyone who would like to assist in the preparations and to remember those who have been lost are invited to attend.

The operation was spearheaded by the ARW with the support of a Naval Service coastal patrol vessel (CPV) and also Air Corps helicopters. High-speed tactical assault craft with ARW teams on board conducted manoeuvres while air-borne teams fast-roped from helicopters onto the deck of the Stena Adventurer. To see photos of the ARW team in action click HERE.

The exercise was designed to enhance the capacity of the Defence Forces to provide the State with a highly specialised maritime armed intervention capability.

Last month the Naval Service conducted close quarter manoeuvres in 'Operation Quixote' off the south-west coast. The exercise involved the entire naval fleet except for the flagship LE Eithne, which performed in gunnery practice, simulated air attacks from the Air Corps and armed naval boarding parties.

The Celtic Mist, the new flagship of the Irish Whale and Dolphin Group, was berthed in Waterford city for the Tall Ships weekend writes Shay Fennelly.  Gifted to the IWDG in May 2011 by the family of a former Irish Prime Minister, Charles Haughey, who declared Irish waters a whale and dolphin sanctuary in 1991.

Celtic Mist left Waterford on Sunday morning in glorious sunshine on passage down the River Suir for the Tall Ships Parade of Sail off Dunmore East watched by thousands of people from the river bank at Passage east, Duncannon and Dunmore East.

The Tall Ships fleet was reviewed by Flag Officer Commanding Naval Service Commodore Mark Mellet and Sean Flood Sail Training Ireland (Board) and a Goodwill Ambassador for Sail Training International past the LE Aoife. Over 1200 young people, many who have never been to sea before, are onboard the 50 tall Ships sailing to Greenock.

On board Celtic Mist are Captain Fiacc Brolchain, Gary Davis, Eithne Griffith, Deirdre Slevin, Conor Ryan and trainees Siobhan Ardener (19) from Killarney, Co Kerry, and Keith Cleere (19) from New Ross, Co Wexford.

The race started slowly at 15.00hrs, five miles south of the Hook Lighthouse in 10 knots of wind and blue skies and headed for the Irish Sea to Scotland.

A trio of French Naval mine-route survey craft are to sail upriver of the River Lee this Friday and are to berth in the Port of Cork at the North Custom House Quay, writes Jehan Ashmore.

The craft BRS Antarès (M 770), BRS Altaïr (M 771) and BRS Aldébaran (M 772) represent all of the three-ship Antarès-class which are based in the Breton naval base of Brest. At 28m long the rather stout-looking craft (photo) weigh some 250 tonnes displacement and have a crew of 23.

Leadship of the class BRS Antarès entered service in 1993 and was followed by the remaining pair which too were built by Chantier (Socarenam) in Boulogne-sur-Mer.

In March the BRS Altaïr accompanied the minehunter CMT Cassiopée (M642) to Dublin for a four-day visit during the St. Patrick's Day festival.

On the naval front, LE Emer was built in Cork's Verolme Dockyard in 1978. She represents the oldest of the eight-strong fleet and is designed from the Naval Service's first purpose built patrol vessel OPV LE Deirdre (P20) but was modified to improve her stability and speed. This vessel was decommissioned several years ago and was converted into a private yacht.

The original BOFORS 40mm L60 gun of the LE Emer was recently upgraded to a BOFORS 40mm L70 to improve range and accuracy of her main armament. She alongside her 65m sisters LE Aoife (P22) and LE Aisling (P23) where all built primarily to patrol the Irish section of the European Economic Zone (EEZ).

During their careers the 'Emer' class vessels have also completed numerous re-supply missions to Irish troops serving overseas with the United Nations and in particular in the Lebanon. A crew compliment of 46 (5 officers) operate the vessels which are all now in their fourth decade of service.

OPV HMS Severn is the third of four 'River' class offshore patrol vessels and like her Irish counterpart is deployed on fishery duties. The 1,677 displacement tonnes vessel was built in 2001 in the UK'S south coast port of Southampton at Woolston Docks. Her home port for the 30 crew is at HM Naval Base in neighbouring Portsmouth.

She becomes the fifth ship to bear the name and with sisters HMS Mersey (P 282) and HMS Tyne (P 281) they are assigned to the Fishery Protection Squadron. Click the ship's diary to follow the ship news. The final member of the River class HMS Clyde (P 257) serves as a Falklands Islands Patrol Vessel (FIPV).

The most modern naval vessel of the eight-strong fleet the LÉ Niamh (P52) is an offshore patrol vessel (OPV) which is equipped with a bow-mounted 76mm gun. To see the crew undertake exercise-drills of the gun, watch the video below.

Two mussel dredger-trawlers made a rare transit of Dalkey Sound, last Friday, writes Jehan Ashmore.

The sound which is located to the south of Dublin Bay is not used by commercial traffic but is frequented by pleasure-craft, local fishing boats from Dun Laoghaire. In addition to occasional traffic by the Irish Naval Service, Marine Institute research vessel RV Celtic Voyager, the GSI's RV Keary and foreign tall-ships.

The vessels were making a southerly direction as they headed across Dublin Bay towards Dalkey Island. Mytilus lowered a mussel cage bucket into the sound which was dragged on two separate occasions over a short distance running parallel between the island and the coast.

The operation was all too brief as the Mytilus then proceeded into Killiney Bay followed closely astern by Branding. Upon entering the neighbouring bay, both vessels conducted dredging activity before continuing south beyond Bray Head.

Mussel grounds are located throughout certain hotspots in the Irish Sea and earlier this month, it is reported that there was a notable increase in mussel dredgers in Bangor, Northern Ireland. The dredgers were the Mytilus and Branding which berthed at the Co. Down harbour after a lengthy period of relative inactivity.

Mytilus was built in The Netherlands by Scheepwerf Van Os Yerseke B.V. and appeared in an episode of the successful BBC TV series 'Coast'. At the time of the broadcast she was registered at Beaumaris, Anglesey and was seen working in the northern approaches of the Menai Straits. The fishery grounds are ideally suited for the growing processes required in farmed mussel production.

Branding was also built by a Dutch shipyard, Kooieman in 1988 and her design is typical of the mussel dredgers based in Wexford. The market for mussels is mainly from the northern European countries of Belgium, France and the Netherlands.
