#IRISH HARBOURS - The latest Marine Notice from the Department of Transport, Tourism and Sport (DTTAS) advises on construction works at Castletownbere Fishery Harbour Centre in Co Cork this week.

The works involve the installation of four steel piles - two in the navigation channel to the inner harbour and two to the west of Dinish Pier.

The works are being advanced by civil engineering crews working from a jack-up barge, which will display the relevant day signals and navigation lights in accordance with collision regulations.

For safety reasons, mariners are requested to proceed slowly and with caution in the approach channel to the Fishery Harbour Centre and to give the works a wide berth. Wave-wash from vessels should also be avoided.

These works are expected to be on-going until mid-December, weather permitting.

Complete details for shipowners, ship operations, shipmasters and seafarers are included in Marine Notice No 57 of 2011, a PDF of which is available to read and download HERE.

Published in Irish Harbours
The Department of Transport today has issued a Marine Notice (No. 35, 2010) to advise that all Irish ships having radio communications or radio navigational equipment, which transmits radio signals, must hold a ship radio licence under the Wireless Telegraphy Acts. This is also a requirement under the International Radio Regulations of the International Telecommunications Union ITU.
The ITU Radio Regulation Article 47.2 specifically lays out the requirement for the operator of a ship to have a recognition or authorisation (Authority To Operate) issued by the administration issuing a ship radio licence, to a ship station. The applicable legislation in Ireland is the Wireless Telegraphy Act 1926; Wireless Telegraphy Act 1972; Communications Regulation Act 2002; and amending legislation, in particular the Wireless Telegraphy (Ship Station Radio Licence) Regulations 2006 (S.I. 414 of 2006)

In order to comply with these regulations, Ireland accepts the following documents as meeting the requirements on board its vessels:

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
