The Department of Transport has been advised that a geophysical and geotechnical surveys is being undertaken by Green Rebel Marine in the Irish Sea to assess cable burial on behalf of MDM.

The survey work was anticipated to start on Monday 19 June and will be completed by the end of September, subject to weather and operational constraints.

Surveys will be conducted by two vessels: the semi-SWATH catamaran Roman Rebel (callsign 2ICA5) which will conduct 24-hr operations, and the Lady Kathleen (callsign EIXT2), a catamaran which will conduct 12-hr operations. Both vessels will display appropriate lights and signals.

As the survey vessels will be restricted in their ability to manoeuvre when surveying, due to the deployment of the towed survey equipment from the vessel for the duration of the survey activities, other vessels are kindly requested to keep a wide berth.

Mariners are advised to keep continuous watch on VHF Channel 16 when navigating the area.

Coordinates and a map of the survey areas as well as contact details can be found in Marine Notice No 40 of 2023, attached below.

The Department of Transport has been advised by the School of Biological, Earth and Environmental Sciences at University College Cork that on on Tuesday 12 June it deployed 12 benthic sensors between the Seven Heads and the Old Head of Kinsale in West Cork.

These sensors are being used in scientific research which aims to track skate using acoustic tracking equipment.

The benthic sensors will be deployed for 12 months. Each sensor consists of a mooring weight and an acoustic sensor for tracking tagged skate in the area. None have surface markers.

A map and coordinates of the sensor positions as well as contact details can be found in Marine Notice No 39 of 2023, attached below.

The Department of Transport has been advised by Donegal County Council that works will begin on the construction of a breakwater outside the entrance of Greencastle Harbour on Lough Foyle in Co Donegal.

These works will begin on Monday 12 June and are anticipated to continue until December 2023, subject to weather and operational constraints.

The works include, but are not limited to, the following main construction elements:

• Construction of a 150m extension to the existing breakwater
• Construction of temporary works to include access roads, storage, temporary quay and weigh bridge at Queensport in Greencastle
• Removal of existing Aids to Navigation (AtoN) and installation of new temporary AtoN’s
• Importation of circa 350,000 tonnes of rock core and rock armour by land and also by sea from Foyle Port
• Placement of circa 350,000 tonnes of rock core and rock armour using split hopper barges, jack-up barge platform and tugs

The works are being carried out by marine civil engineering contractors working from a temporary quay at the Queensport in Greencastle and the Greencastle pontoon using work vessels, jack up barges, heavy civil engineering plant and equipment. Divers may also be employed from time to time on site.

For safety reasons, mariners are advised to proceed slowly and with caution within the area south-west of the entrance to Greencastle Harbour and to give the works area a wide berth. Wave wash from vessels should be avoided.

A map and plan of the planned works as well as contact details can be found in Marine Notice No 38 of 2023, attached below.

The Department of Transport has been advised by PSE Kinsale Energy Limited that rock placement works will take place in the Celtic Sea between this Saturday 10 June and the end of July.

Works will take place at various locations along the routes of decommissioned, but remaining in-situ, pipelines to the Kinsale Head and Seven Heads Gas Fields in the Celtic Sea.

The start date of the works and the estimated duration of 20 days are subject to weather conditions and operational constraints.

Works will be conducted using the vessels Rollingstone (callsign PHYR) and Flintstone (PBZD). Both will operate during day and night hours and will display all appropriate lights and signals.

Within each of the defined work areas, the vessels will be undertaking rock placement works using a fallpipe system and associated acoustic survey works using a multi-beam echosounder.

All other vessels, particularly those engaged in fishing, are requested to give the vessels a wide berth and keep a sharp lookout in the relevant areas. The vessels can be contacted on VHF Channel 13.

The Department of Transport wishes to highlight the provisions of SOLAS Chapter V to small, privately owned recreational craft.

Although regulation 34 of Chapter V — “Safe navigation and avoidance of dangerous situations” — only applies when proceeding to sea, the department advises all recreational craft users to comply with the voyage planning principles.

These were previously highlighted in Marine Notice No 19 of 2021 following an MCIB report into the rescue of five Kinsale Yacht Club sailors from the yacht Loa Zour amid severe storm conditions off the Spanish coast in June 2019.

In Marine Notice No 30 of 2023, the department underscores this as well as the benefits of radar reflectors, the need for access to an illustrated table of the recognised life-saving signals, requirements around the assistance of other craft, the consequences of misuse of distress signals and more.

Full details can be found in Marine Notice No 30 of 2023 attached below.

The Department of Transport has issued an updated advisory for 2023 over the risk of vessels becoming entangled in ropes used in pot fishing.

Marine Notice No 31 of 2023 supersedes No 43 of 2021 and reminds all vessel owners, agents, shipmasters, skippers, fishers, yachtsmen, seafarers and those engaged in pot fishing about the risks of vessels’ propellers becoming entangled in ropes of marker buoys used to indicate the position of pots used for fishing lobster, crab or other fish or shellfish.

This can occur because the length of rope used to fix marker buoys is too long, resulting in the line floating on or just below the surface.

The use of too long a line of rope can result in a situation where even vessels that have taken a wide berth around marker buoys could have their propellers fouled by the rope.

Specifically, the department reminds those engaged in pot fishing not to use unsuitable ‘floats’ (eg empty drink cans, plastic bottles, dark-coloured floats, etc) which offer poor visibility and/or could be mistaken for floating debris.

Fishers who carry out pot fishing (whether commercially or non-commercially) are reminded of their obligations to other users of the sea.

Furthermore, non-commercial pot fishers are reminded of the regulations made by the Department of Agriculture, Food and the Marine covering such activity (SI No 31 of 2016 - Non-Commercial Pot Fishing (Lobster and Crab) Regulations 2016) which, inter alia, limits the numbers of pots permitted per boat to a maximum of six, and such pot fishing to the months of May to September.

Any mariners who spot any marker buoys/ropes (or any other object) in the water, which they deem to represent a danger to navigation, should communicate information on same to other vessels in the area and to the Irish Coast Guard or to the local competent authority so that a hazard warning can be issued if appropriate, and any required follow-up action can be taken.

An updated guide on good practice for pots and marker buoys is included in Marine Notice No 31 of 2023 attached below.

The Ocean Research Conservation Association of Ireland (ORCA Ireland) intends to deploy a data buoy as an aid to navigation off the South Coast of Ireland this weekend.

The deployment will take place on Saturday 22 April, subject to weather and operational constraints. The buoy will remain in place until November.

The buoy will be deployed by the vessel Sabrina II (callsign EIQR2), a RO-RO barge. During the deployment, this vessel will be restricted in its ability to manoeuvre. All other vessels are requested to leave a wide berth during the deployment operation.

Further details, including coordinates, a map and contact information, can be found in Marine Notice No 32 of 2023 attached below.

Next Geosolutions will perform a detailed marine, geotechnical and UXO survey on behalf of Nexans for CIDAC as part of the Celtic Interconnector project.

These surveys will follow the planned route of the Celtic Interconnector offshore power cable route between the South East Coast of Ireland and the coast of France.

Works will begin on Saturday 29 April (subject to weather and operational constraints) and will take approximately 169 days, of which 26 will be within Irish waters.

The surveys will be conducted by two vessels for both offshore and nearshore operations. The OSV Relume (callsign C6TR4) will be conducting the detailed marine, geotechnical and UXO survey works in the offshore areas and operations will be conducted on a 24-hour basis. Nearshore operations will be conducted by the vessel Deep Volans (callsign PETL) on a 12-hours basis.

Both vessels will display the relevant lights and shapes during periods of restricted manoeuvrability and adhere to COLREGS and all licensing requirements.

During operations both vessels will be running survey lines, and all other vessels operating in the area are requested to leave a wide berth. Both survey vessels will keep a listening watch on VHF Channel 16 and will actively transmit an AIS signal. A listening watch will also be maintained on VTS VHF channels as appropriate.

Maps and coordinates of the survey areas as well as contact details can be found in Marine Notice No 29 of 2023 attached below.

Geotechnical site investigations will be conducted on the Codling Wind Park project site off the coast of Co Wicklow from early next month.

Project works will commence on Monday 8 May and continue through to late July, subject to weather and operational constraints.

The Codling Wind Park is an offshore wind energy project on the Codling Bank some 13km off the East Coast of Ireland. The geotechnical investigation (including boreholes and cone penetration tests) is intended to take place at 15 different locations within the project work site.

Operations will be conducted by the Dutch Pearl (callsign PBZP), a support vessel/tug, and the Excalibur (callsign YJKQ5), a jack-up barge, both of which are engaged in site investigations at the Kish and Bray banks this month.

The Excalibur will be positioned at each of the investigation points for several days which may extend in the event of inclement weather. The Dutch Pearl will be assisting the Excalibur in its daily operations and towing the barge between investigation points. The standby tug will be at anchor on the project site and will be conducting transits between the site and Dublin Port.

Both vessels will display the relevant light and shapes as required under COLREGS. Both vessels will keep continuous watch on VHF Channels 16 and 72. During operations, the vessels will be restricted in their ability to manoeuvre. All other vessels are requested to leave a wide berth during the operations.
