The Department of Transport has been advised of the deployment of a metocean data buoy by University College Dublin west of Inishmaan, some 6.6 nautical miles off Eeragh Lighthouse on Rock Island.

This deployment is scheduled to take place from Sunday 22 October for a period of up to seven days, subject to weather and operational constraints.

It will be carried out by the MV Chateau-Thierry (callsign EIHK6) which will display appropriate lights and signals.

Navigational warnings will be issued by radio when the marker buoy deployment takes place. A yellow special mark plastic buoy, IALA category 3 and 2.5m in diameter, will be used with a navigation light flashing white every 20 seconds at 4.1 meters above the surface.

Coordinates and a map of the deployment area, as well as contact details, can be found in Marine Notice No 65 of 2023, attached below.

The Department of Transport has been advised by Fuinneamh Sceirde Teoranta (FST) that a metocean survey comprising one large metocean buoy and two trawl resistant seabed frames will be deployed at the site of the proposed Sceirde Rocks Windfarm in north Galway Bay off southwestern Connemara.

The deployment will take place between this Saturday 29 July and the end of August, subject to weather and operational constraints.

Equipment will remain in place for up to 24 months, and periodic service visits to the equipment will take place throughout the survey period.

The metocean buoy has a hull diameter of 3.6m and focal height of 4m. The buoy is yellow in colour and displays a St Andrew’s Cross. It is mounted with one automatic identification system (AIS) unit (161.975 MHz) and one navigation light (sequence Fl(5) 20s, range 3nm).

The buoy is double moored using a mooring chain and sinker blocks. The anchor and sinkers will be placed approximately 200m away from the metocean buoy. The mooring line will consist of approximately 200m of chain per leg, partially suspended in the water column and partially laying on the seabed.

The trawl-resistant seabed frames are approximately one square metre each and will be unmarked.

This metocean equipment will be deployed from the ILV Granuaile (callsign EIPT), which will operate on a 24-hour basis. Throughout operations, the vessel will display the appropriate lights and shapes as required under the COLREGS Rule 27 (b).

During operations, the vessel will be restricted in its ability to manoeuvre. Vessels are requested to leave a wide berth during the deployment operations.

Radio transmissions will be conducted with other seafarers to notify them of the operations. All vessels will monitor VHF Channel 16 for emergency communications with other seafarers and then mutually agree another channel to switch to for further discussion as needed.

Coordinates and a map of the deployment area as well as contact details can be found in Marine Notice No 46 of 2023, attached below.

Techworks Marine is deploying three surface buoys with single-point moorings for a metocean survey campaign at the site of the proposed Clogherhead Offshore Wind Farm.

It follows a geophysical survey campaign conducted by Alpha Marine this past summer, as previously reported on Afloat.ie.

These deployments are expected to be completed over a two-day period, at the next available weather window from Sunday 6 November, subject to weather and operational constraints.

Once deployed, the met ocean devices will remain on site for a period of up to 12 months.

The survey campaign will be undertaken within the proposed Clogherhead Offshore Wind Farm site, located some 10km from the Co Louth coast. Detailed coordinates and a map of the survey area are included in Marine Notice No 76 of 2022, attached below.

Three yellow buoys will be deployed, each with a hull diameter of 1.2m and a nominal freeboard of 0.7m. The buoys will display a St Andrew’s Cross day mark, and are fitted with a radar reflector and navigation light with a three nautical mile range, flashing a sequence of five flashes every 20 seconds.

Deployment operations will be conducted by the twin-hulled multi-cat work vessel MPV Skua (callsign 2GDE3).

During works, the vessel will be restricted in its ability to manoeuvre so all other vessels are requested to leave a wide berth during the deployment operations. Radio transmissions will be conducted with other seafarers to notify them of the operations.

Marine Notice 37 of 2021 advised of the deployment of one floating lidar buoy and two wave buoys at the Dublin Array offshore wind farm on the Bray and Kish Banks.

The Department of Transport has now been advised by Partrac Ltd that all three Metocean buoys are scheduled to be serviced soon over a period of two days.

Weather permitting, it is expected that the two wave buoys will be recovered and redeployed in the three-week period between tomorrow, Friday 11 February and Friday 4 March.

The floating lidar buoy will be towed from its location on Bray Bank to Wicklow Harbour for routine maintenance overnight and towed back to Bray Bank for redeployment in its current position. This recovery and redeployment will take place in the three-week period between Thursday 24 February 2022 and Friday 18 March.

The AMS Retriever (callsign MEHI8) will recover and redeploy all three buoys. The floating lidar buoy will be towed some 30 metres astern of the AMS Retriever at a maximum speed of 3.5 knots.

During this time, the vessel will be restricted in its ability to manoeuvre. As such, vessels operating within this area are requested to keep their distance, maintaining a safety zone around the deployment vessel, and pass at minimum speed to reduce vessel wash.

Radio transmissions will be conducted with VTS and other seafarers to notify them of the buoy operations.

Coordinates of the buoy locations and contact details can be found in Marine Notice No 10 of 2022, attached below.

Published in News Update

Partrac Ltd intend to deploy three Metocean buoys at the Dublin Array offshore wind farm in a one-day operation some time between this Wednesday 9 and Wednesday 23 June, weather permitting.

One floating lidar buoy and two wave buoys will be deployed by the AMS Retriever (callsign MEHI8) which will be displaying all appropriate lights and shapes.

The floating lidar buoy has a square footprint with an area of 4m2 and a height of some 4m above the water line. It is yellow in colour and has a St Andrew’s cross on top.

The wave buoys are spherical in shape with a diameter of around 1.1m. When deployed, the wave buoys appear clear with a yellow hull.

Both the floating lidar buoy and the wave buoys have a yellow light which emits five flashes every 20 seconds. The light is visible for up to three nautical miles.

The floating lidar buoy will be deployed for a period of four to eight weeks. It will then be moved to a permanent position in the south end of Dublin Array where it will be deployed for 18 months. The wave buoys will be deployed for a period of 12 months.

The floating lidar buoy will be towed approximately 30m astern of the AMS Retriever at a maximum speed of four knots.

As such, the vessel will be restricted in its ability to manoeuvre so all other boats operating in proximity are requested to keep their distance, maintaining a safety zone around the deployment vessel and pass at minimum speed to reduce vessel wash.

Details of the buoy locations are included in Marine Notice No 37 of 2021 which can be downloaded below.

Metocean devices will be deployed in the Irish Sea off the Wicklow coast) in the coming days, weather permitting, to provide environmental data for the development of the Arklow Bank Wind Park.

Similar to last autumn’s deployment, four separate devices to monitor waves and currents will be deployed, which will include a seabed frame with the sensors mounted on it, an anchoring system, and a surface marker buoy.

The devices will be deployed using either the AMS Retriever (Callsign MEHI8) or Husky (Callsign 2EQI7), both versatile multi-purpose shallow draft tugs. The devices will remain in place for approximately six months, serviced on a three-monthly basis.

During deployment and recovery operations, the AMS vessel will be restricted in its ability to manoeuvre. The devices will be located using yellow special mark buoys which will have the relevant markers and ATON characters.

The location of the devices will be off the Wicklow coastline as detailed in Marine Notice No 31 of 2020, which is available to download below.

Published in Marine Warning

Metocean devices will be deployed in the Irish Sea off the Wicklow coast in late October/early November, subject to weather conditions, to facilitate the development of the Arklow Bank Wind Park.

Five separate devices are being deployed which will include a seabed frame with sensors mounted on it, an anchoring system and a surface marker buoy, according to a recent Marine Notice from the Department of Transport, Tourism and Sport.

The devices will be located off the Wicklow coastline, with locations detailed in Marine Notice No 48 of 2019, a PDF of which is available to read or download HERE.

The devices will be deployed using the shallow draft tug AMS Retriever (callsign MEHI8) and will remain in place for approximately one year, serviced on a quarterly basis.

During deployment and recovery operations, the AMS Retriever will be restricted in its ability to manoeuvre.

The devices, similar to that recently deployed at the Oriel Windfarm in Dundalk Bay, will be located using yellow special mark buoys which will have relevant markers and ATON characters.

The Irish Coast Guard

The Irish Coast Guard is Ireland's fourth 'Blue Light' service (along with An Garda Síochána, the Ambulance Service and the Fire Service). It provides a nationwide maritime emergency organisation as well as a variety of services to shipping and other government agencies.

The purpose of the Irish Coast Guard is to promote safety and security standards, and by doing so, prevent as far as possible, the loss of life at sea, and on inland waters, mountains and caves, and to provide effective emergency response services and to safeguard the quality of the marine environment.

The Irish Coast Guard has responsibility for Ireland's system of marine communications, surveillance and emergency management in Ireland's Exclusive Economic Zone (EEZ) and certain inland waterways.

It is responsible for the response to, and co-ordination of, maritime accidents which require search and rescue and counter-pollution and ship casualty operations. It also has responsibility for vessel traffic monitoring.

Operations in respect of maritime security, illegal drug trafficking, illegal migration and fisheries enforcement are co-ordinated by other bodies within the Irish Government.

On average, each year, the Irish Coast Guard is expected to:

  • handle 3,000 marine emergencies
  • assist 4,500 people and save about 200 lives
  • task Coast Guard helicopters on missions

The Coast Guard has been around in some form in Ireland since 1908.

Coast Guard helicopters

The Irish Coast Guard has contracted five medium-lift Sikorsky Search and Rescue helicopters deployed at bases in Dublin, Waterford, Shannon and Sligo.

The helicopters are designated wheels up from initial notification in 15 minutes during daylight hours and 45 minutes at night. One aircraft is fitted and its crew trained for under slung cargo operations up to 3000kgs and is available on short notice based at Waterford.

These aircraft respond to emergencies at sea, inland waterways, offshore islands and mountains of Ireland (32 counties).

They can also be used for assistance in flooding, major inland emergencies, intra-hospital transfers, pollution, and aerial surveillance during daylight hours, lifting and passenger operations and other operations as authorised by the Coast Guard within appropriate regulations.

Irish Coastguard FAQs

The Irish Coast Guard provides nationwide maritime emergency response, while also promoting safety and security standards. It aims to prevent the loss of life at sea, on inland waters, on mountains and in caves; and to safeguard the quality of the marine environment.

The main role of the Irish Coast Guard is to rescue people from danger at sea or on land, to organise immediate medical transport and to assist boats and ships within the country's jurisdiction. It has three marine rescue centres in Dublin, Malin Head, Co Donegal, and Valentia Island, Co Kerry. The Dublin National Maritime Operations centre provides marine search and rescue responses and coordinates the response to marine casualty incidents with the Irish exclusive economic zone (EEZ).

Yes, effectively, it is the fourth "blue light" service. The Marine Rescue Sub-Centre (MRSC) Valentia is the contact point for the coastal area between Ballycotton, Co Cork and Clifden, Co Galway. At the same time, the MRSC Malin Head covers the area between Clifden and Lough Foyle. Marine Rescue Co-ordination Centre (MRCC) Dublin covers Carlingford Lough, Co Louth to Ballycotton, Co Cork. Each MRCC/MRSC also broadcasts maritime safety information on VHF and MF radio, including navigational and gale warnings, shipping forecasts, local inshore forecasts, strong wind warnings and small craft warnings.

The Irish Coast Guard handles about 3,000 marine emergencies annually, and assists 4,500 people - saving an estimated 200 lives, according to the Department of Transport. In 2016, Irish Coast Guard helicopters completed 1,000 missions in a single year for the first time.

Yes, Irish Coast Guard helicopters evacuate medical patients from offshore islands to hospital on average about 100 times a year. In September 2017, the Department of Health announced that search and rescue pilots who work 24-hour duties would not be expected to perform any inter-hospital patient transfers. The Air Corps flies the Emergency Aeromedical Service, established in 2012 and using an AW139 twin-engine helicopter. Known by its call sign "Air Corps 112", it airlifted its 3,000th patient in autumn 2020.

The Irish Coast Guard works closely with the British Maritime and Coastguard Agency, which is responsible for the Northern Irish coast.

The Irish Coast Guard is a State-funded service, with both paid management personnel and volunteers, and is under the auspices of the Department of Transport, Tourism and Sport. It is allocated approximately 74 million euro annually in funding, some 85 per cent of which pays for a helicopter contract that costs 60 million euro annually. The overall funding figure is "variable", an Oireachtas committee was told in 2019. Other significant expenditure items include volunteer training exercises, equipment, maintenance, renewal, and information technology.

The Irish Coast Guard has four search and rescue helicopter bases at Dublin, Waterford, Shannon and Sligo, run on a contract worth 50 million euro annually with an additional 10 million euro in costs by CHC Ireland. It provides five medium-lift Sikorsky S-92 helicopters and trained crew. The 44 Irish Coast Guard coastal units with 1,000 volunteers are classed as onshore search units, with 23 of the 44 units having rigid inflatable boats (RIBs) and 17 units having cliff rescue capability. The Irish Coast Guard has 60 buildings in total around the coast, and units have search vehicles fitted with blue lights, all-terrain vehicles or quads, first aid equipment, generators and area lighting, search equipment, marine radios, pyrotechnics and appropriate personal protective equipment (PPE). The Royal National Lifeboat Institution (RNLI) and Community Rescue Boats Ireland also provide lifeboats and crews to assist in search and rescue. The Irish Coast Guard works closely with the Garda Siochána, National Ambulance Service, Naval Service and Air Corps, Civil Defence, while fishing vessels, ships and other craft at sea offer assistance in search operations.

The helicopters are designated as airborne from initial notification in 15 minutes during daylight hours, and 45 minutes at night. The aircraft respond to emergencies at sea, on inland waterways, offshore islands and mountains and cover the 32 counties. They can also assist in flooding, major inland emergencies, intra-hospital transfers, pollution, and can transport offshore firefighters and ambulance teams. The Irish Coast Guard volunteers units are expected to achieve a 90 per cent response time of departing from the station house in ten minutes from notification during daylight and 20 minutes at night. They are also expected to achieve a 90 per cent response time to the scene of the incident in less than 60 minutes from notification by day and 75 minutes at night, subject to geographical limitations.

Units are managed by an officer-in-charge (three stripes on the uniform) and a deputy officer in charge (two stripes). Each team is trained in search skills, first aid, setting up helicopter landing sites and a range of maritime skills, while certain units are also trained in cliff rescue.

Volunteers receive an allowance for time spent on exercises and call-outs. What is the difference between the Irish Coast Guard and the RNLI? The RNLI is a registered charity which has been saving lives at sea since 1824, and runs a 24/7 volunteer lifeboat service around the British and Irish coasts. It is a declared asset of the British Maritime and Coast Guard Agency and the Irish Coast Guard. Community Rescue Boats Ireland is a community rescue network of volunteers under the auspices of Water Safety Ireland.

No, it does not charge for rescue and nor do the RNLI or Community Rescue Boats Ireland.

The marine rescue centres maintain 19 VHF voice and DSC radio sites around the Irish coastline and a digital paging system. There are two VHF repeater test sites, four MF radio sites and two NAVTEX transmitter sites. Does Ireland have a national search and rescue plan? The first national search and rescue plan was published in July, 2019. It establishes the national framework for the overall development, deployment and improvement of search and rescue services within the Irish Search and Rescue Region and to meet domestic and international commitments. The purpose of the national search and rescue plan is to promote a planned and nationally coordinated search and rescue response to persons in distress at sea, in the air or on land.

Yes, the Irish Coast Guard is responsible for responding to spills of oil and other hazardous substances with the Irish pollution responsibility zone, along with providing an effective response to marine casualties and monitoring or intervening in marine salvage operations. It provides and maintains a 24-hour marine pollution notification at the three marine rescue centres. It coordinates exercises and tests of national and local pollution response plans.

The first Irish Coast Guard volunteer to die on duty was Caitriona Lucas, a highly trained member of the Doolin Coast Guard unit, while assisting in a search for a missing man by the Kilkee unit in September 2016. Six months later, four Irish Coast Guard helicopter crew – Dara Fitzpatrick, Mark Duffy, Paul Ormsby and Ciarán Smith -died when their Sikorsky S-92 struck Blackrock island off the Mayo coast on March 14, 2017. The Dublin-based Rescue 116 crew were providing "top cover" or communications for a medical emergency off the west coast and had been approaching Blacksod to refuel. Up until the five fatalities, the Irish Coast Guard recorded that more than a million "man hours" had been spent on more than 30,000 rescue missions since 1991.

Several investigations were initiated into each incident. The Marine Casualty Investigation Board was critical of the Irish Coast Guard in its final report into the death of Caitriona Lucas, while a separate Health and Safety Authority investigation has been completed, but not published. The Air Accident Investigation Unit final report into the Rescue 116 helicopter crash has not yet been published.

The Irish Coast Guard in its present form dates back to 1991, when the Irish Marine Emergency Service was formed after a campaign initiated by Dr Joan McGinley to improve air/sea rescue services on the west Irish coast. Before Irish independence, the British Admiralty was responsible for a Coast Guard (formerly the Water Guard or Preventative Boat Service) dating back to 1809. The West Coast Search and Rescue Action Committee was initiated with a public meeting in Killybegs, Co Donegal, in 1988 and the group was so effective that a Government report was commissioned, which recommended setting up a new division of the Department of the Marine to run the Marine Rescue Co-Ordination Centre (MRCC), then based at Shannon, along with the existing coast radio service, and coast and cliff rescue. A medium-range helicopter base was established at Shannon within two years. Initially, the base was served by the Air Corps.

The first director of what was then IMES was Capt Liam Kirwan, who had spent 20 years at sea and latterly worked with the Marine Survey Office. Capt Kirwan transformed a poorly funded voluntary coast and cliff rescue service into a trained network of cliff and sea rescue units – largely voluntary, but with paid management. The MRCC was relocated from Shannon to an IMES headquarters at the then Department of the Marine (now Department of Transport) in Leeson Lane, Dublin. The coast radio stations at Valentia, Co Kerry, and Malin Head, Co Donegal, became marine rescue-sub-centres.

The current director is Chris Reynolds, who has been in place since August 2007 and was formerly with the Naval Service. He has been seconded to the head of mission with the EUCAP Somalia - which has a mandate to enhance Somalia's maritime civilian law enforcement capacity – since January 2019.
