The UK's Maritime & Coastguard Agency in conjunction with RWE npower renewables, the RNLI and RAF Search and Rescue, are due to exercise communications, co-ordination and response to a series of mock-maritime incidents in and around the wind turbines at the North Hoyle and Rhyl Flats Offshore Wind Farms on the Irish Sea.

Rhyl Flats Offshore Wind Farm is a 25 turbine wind farm approximately 8 km north east of Llandudno in North Wales. It is Wales' second offshore wind farm and the third offshore wind farm to be built within Liverpool Bay. It has a maximum rated output of 90 MW.

The Exercise is due to take place on Sunday 5th September.

The exercise will be coordinated by Holyhead Coastguard, and involves multiple agencies, including the North Hoyle and Rhyl Flats wind farm operators, maintenance teams and a number of service vessels.

Jim Paton, Rescue Co-ordination Centre manager at Holyhead Coastguard said:

"We are very keen to practise various elements of a search and rescue within a wind farm and to test rescue and evacuation procedures for 'walking wounded' from intermediate and lower platforms of a wind farm tower. With colleagues in the RNLI we will exercise the appointment of the Rhyl RNLI all weather lifeboat as on scene co-ordinator to search the surface sea area for missing people with multiple search units employed.

"We want to be able to test procedures for the rescue and evacuation of persons from a turbine nacelle and with the RAF, test a helicopter evacuation of a casualty from the nacelle of a wind turbine. We will also be exercising winching procedures within a wind farm complex using lifeboats, a helicopter and a wind farm service vessel all working with each other. We expect the exercise to take about four (4) hours from midday to 4.00 pm."

The exercise will begin with Holyhead Coastguard receiving a call reporting a 4x4 vehicle and trailer parked in Rhyl overnight. The first informant will also explain that he had seen two people from this vehicle launching a small boat from the slipway opposite at around 8.00 pm the previous evening, and who haven't been seen since. Additionally the Coastguard will hear about the need for an individual to be airlifted from somewhere within the North Hoyle offshore wind farm .

Jim Paton continued

"As wind farms become larger and more involved; an emergency service such as the Coastguard must be fully aware of the challenges of search and rescue within such complexes when the weather and sea conditions at the time of the incident may be extremely hostile."

Marine Institute Research Vessel Tom Crean

Ireland’s new marine research vessel will be named the RV Tom Crean after the renowned County Kerry seaman and explorer who undertook three major groundbreaking expeditions to the Antarctic in the early years of the 20th Century which sought to increase scientific knowledge and to explore unreached areas of the world, at that time.

Ireland's new multi-purpose marine research vessel RV Tom Crean, was delivered in July 2022 and will be used by the Marine Institute and other State agencies and universities to undertake fisheries research, oceanographic and environmental research, seabed mapping surveys; as well as maintaining and deploying weather buoys, observational infrastructure and Remotely Operated Vehicles.

The RV Tom Crean will also enable the Marine Institute to continue to lead and support high-quality scientific surveys that contribute to Ireland's position as a leader in marine science. The research vessel is a modern, multipurpose, silent vessel (designed to meet the stringent criteria of the ICES 209 noise standard for fisheries research), capable of operating in the Irish Exclusive Economic Zone (EEZ). The Tom Crean is able to go to sea for at least 21 days at a time and is designed to operate in harsh sea conditions.

Irish Marine Research activities

The new state-of-the-art multi-purpose marine research vessel will carry out a wide range of marine research activities, including vital fisheries, climate change-related research, seabed mapping and oceanography.

The new 52.8-metre modern research vessel, which will replace the 31-metre RV Celtic Voyager, has been commissioned with funding provided by the Department of Agriculture, Food and the Marine approved by the Government of Ireland.

According to Aodhán FitzGerald, Research Vessel Manager of the MI, the RV Tom Crean will feature an articulated boom crane aft (6t@ 10m, 3T@ 15m), located on the aft-gantry. This will be largely used for loading science equipment and net and equipment handling offshore.

Mounted at the stern is a 10T A-frame aft which can articulate through 170 degrees which are for deploying and recovering large science equipment such as a remotely operated vehicle (ROV’s), towed sleds and for fishing operations.

In addition the fitting of an 8 Ton starboard side T Frame for deploying grabs and corers to 4000m which is the same depth applicable to when the vessel is heaving but is compensated by a CTD system consisting of a winch and frame during such operations.

The vessel will have the regulation MOB boat on a dedicated davit and the facility to carry a 6.5m Rigid Inflatable tender on the port side.

Also at the aft deck is where the 'Holland 1' Work class ROV and the University of Limericks 'Etain' sub-Atlantic ROV will be positioned. In addition up to 3 x 20’ (TEU) containers can be carried.

The newbuild has been engineered to endure increasing harsher conditions and the punishing weather systems encountered in the North-East Atlantic where deployments of RV Tom Crean on surveys spent up to 21 days duration.

In addition, RV Tom Crean will be able to operate in an ultra silent-mode, which is crucial to meet the stringent criteria of the ICES 209 noise standard for fisheries research purposes.

The classification of the newbuild as been appointed to Lloyds and below is a list of the main capabilities and duties to be tasked by RV Tom Crean:

  • Oceanographic surveys, incl. CTD water sampling
  • Fishery research operations
  • Acoustic research operations
  • Environmental research and sampling operation incl. coring
  • ROV and AUV/ASV Surveys
  • Buoy/Mooring operations
