Further to previous installation works on the Havhingsten fibre optic telecommunication cable system in the Irish Sea, post-lay inspection and burial (PLIB) of the cable is planned to begin later this week.

Works outside Irish and Isle of Man territorial waters are will start on Friday 14 January and continue until next Thursday 20 January, subject to weather.

It is advised that extra care is taken when vessels are operating near this area and that no vessel should trawl within 500m.

Installation will be via industry-standard burial tools including water jetting with remote operated vehicle (ROV). The target cable burial depth is 1.5m below seabed level in the region.

There will be two locations where PLIB will be performed: at Final Splice (FS) location outside Irish territorial waters, and at Branching Unit (BU) location outside of Isle of Man territorial waters.

The operations will be conducted by the cable installation vessel CS Ile d’Aix (callsign FICI) which will be working on a 24-hour basis, and will display appropriate day shapes and lights during reduced visibility and night operations.

All vessels operating within this area are requested to keep their distance and pass at minimum speed to reduce vessel wash.

For more information, including coordinates and contact details, see Marine Notice No 01 of 2022 attached below.

The latest Marine Notice from the Department of Transport advises that the Informing and Mapping the Offshore Renewable Environment (I-MORE) Survey will be carried out in the North Irish Sea from early in the New Year.

From 4-13 January 2022, the RV Celtic Explorer (callsign EIGB) will carry out the survey on a 24-hour schedule using the Manta–200 Seabed Cone Penetration Testing (CPT) system.

The aim of this survey is to gather critical seabed data to feed into existing postdoc and group research across a range of disciplines, including marine geotechnics and physical geology, to better understand the geology and engineering properties of the sediment in this area and to identify potential geohazards to infrastructure development.

Installation of the Havhingsten fibre optic telecommunication cable system is planned from Monday 23 August until Thursday 23 September in the Irish Sea outside of the Irish 12-nautical-mile zone.

Works within 12 nautical miles of Ireland’s mainland are planned from December 2021 subject to weather and operational conditions.

There will also be associated rock placement operations post-cable installation at four locations within the western Irish Sea and these works are expected in between October and December, weather permitting.

The entire cable system will comprise marine elements that pass from Denmark to the UK (NE region), and from the UK (NW) to Ireland, with two segments installed into landfalls on the Isle of Man. The cable route for the western Irish Sea region lands at Loughshinny in north Co Dublin.

Installation will be via industry standard burial tools including water jetting and ploughing. Target cable burial depth is 1.5m below seabed level in the region.

It is anticipated that installation operations in UK/Irish waters will occupy up to a maximum 500m width (250m either side of cable). The cable itself will occupy only 40mm of the seabed. Expected speed of installation will be approximately 17km per day.

Works will be conducted by the cable installation vessel CS Recorder (callsign MATL3) which will operate 24 hours a day and will display appropriate day shapes and lights during reduced visibility and night operations.

All vessels operating within its vicinity are requested to keep their distance, and pass at minimum speed to reduce vessel wash.

Full details, including coordinates for the work areas and rock armour placements, are included in Marine Notice No 45 of 2021 which can be downloaded below.

At a distance of 50-miles, a tunnel under the Irish Sea, connecting Wales and Ireland has been suggested UK Secretary of State for Transport Grant Shapps.

In an interview with the Financial Times, Shapps suggested a tunnel between Wales and Ireland as an alternative to Prime Minister Boris Johnson's scheme to link Scotland with Northern Ireland.

When questioned on the idea of linking Northern Ireland with mainland Britain, he said: "Why not?"

The Daily Express reported that the tunnel could be from Holyhead to Dublin and had been previously been priced at £15bn. It would be twice as long as the Channel Tunnel linking Kent and France (see other story on Irish Ferries). 

In the Sunday Times, Political Editor Tim Shipman reported that a feasibility study could be launched in the next few weeks.

NorthWalesLive has more on this story.

Following the recent notice of geophysical surveys for the Codling Wind Park comes news of a series of geotechnical surveys in the Irish Sea off Wicklow for the project set to commence tomorrow, Monday 26 April.

Works to characterise the wind park area will be conducted until Saturday 26 June, weather permitting, from the LB Jill (callsign WDH 6208) on a 24-hour basis. The vessel will display appropriate lights and shapes.

As the LB Jill will be restricted in ability to manoeuvre, all vessels operating within the work area are requested to keep their distance, maintaining a safety zone around the geotechnical investigation vessel, and pass at minimum speed to reduce vessel wash.

Further details including coordinates for the survey works are included in Marine Notice No 28 of 2021, which can be downloaded below.

The Department of Transport has been advised that Codling Wind Park Limited intend to conduct a series of geophysical surveys in the Irish Sea off Dublin and Wicklow from Wednesday 14 April to Wednesday 26 May, weather permitting.

This work is intended to provide options for export cable routes to possible landfall options in the areas of Poolbeg, Dun Laoghaire, Greystones and Wicklow.

A total of two vessels will be working on the project. Arctic Ocean (callsign OZGP2) will undertake geophysical operations to characterise the export cable sites (weather permitting). Survey operations will be conducted on a 24-hour basis.

Meanwhile, Faraday (callsign MJZX5) will undertake geophysical operations (weather permitting). Survey operations will be conducted on a 12-hour basis.

Throughout survey operations, the vessels will be displaying the appropriate lights and shapes. As both vessels will be towing survey equipment, they will also require large turning circles and will be restricted in their ability to manoeuvre.

All vessels operating within the work area are requested to keep their distance, maintaining at least the 500m safety zone around the survey vessel and pass at minimum speed to reduce vessel wash.

Further details including coordinated and contacts are included in Marine Notice No 21 of 2021, a PDF of which can be downloaded below.

Two ex-presidents of the UK’s Institution of Civil Engineers (ICE) have been tasked with carrying out a study on the feasibility of an Irish Sea crossing between Britain and Northern Ireland.

As industry publication New Civil Engineer reports, Douglas Oakervee and Gordon Masterson have been charged by British Prime Minister Boris Johnson with evaluating the various proposals.

These include an “underground roundabout” beneath the Isle of Man that would connect separate tunnels Northern Ireland, Scotland and England — an idea inspired by a similar project in the Faroe Islands.

Another proposal for a Northern Ireland-Scotland tunnel suggests that it could help create a new “capital cities axis” stretching from Dublin to Edinburgh.

The possibility of a road-rail link between Northern Ireland and mainland Britain returned to the agenda earlier this year following Brexit, with one of the options mooted being a a “floating underwater tunnel” along the sea bed, as previously discussed by our own WM Nixon.

Dublin Bay

Dublin Bay on the east coast of Ireland stretches over seven kilometres, from Howth Head on its northern tip to Dalkey Island in the south. It's a place most Dubliners simply take for granted, and one of the capital's least visited places. But there's more going on out there than you'd imagine.

The biggest boating centre is at Dun Laoghaire Harbour on the Bay's south shore that is home to over 1,500 pleasure craft, four waterfront yacht clubs and Ireland's largest marina.

The bay is rather shallow with many sandbanks and rocky outcrops, and was notorious in the past for shipwrecks, especially when the wind was from the east. Until modern times, many ships and their passengers were lost along the treacherous coastline from Howth to Dun Laoghaire, less than a kilometre from shore.

The Bay is a C-shaped inlet of the Irish Sea and is about 10 kilometres wide along its north-south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is situated in the northwest part of the bay, where one of two major inshore sandbanks lie, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams.

Dublin Bay FAQs

There are approximately ten beaches and bathing spots around Dublin Bay: Dollymount Strand; Forty Foot Bathing Place; Half Moon bathing spot; Merrion Strand; Bull Wall; Sandycove Beach; Sandymount Strand; Seapoint; Shelley Banks; Sutton, Burrow Beach

There are slipways on the north side of Dublin Bay at Clontarf, Sutton and on the southside at Dun Laoghaire Harbour, and in Dalkey at Coliemore and Bulloch Harbours.

Dublin Bay is administered by a number of Government Departments, three local authorities and several statutory agencies. Dublin Port Company is in charge of navigation on the Bay.

Dublin Bay is approximately 70 sq kilometres or 7,000 hectares. The Bay is about 10 kilometres wide along its north-south base, and seven km in length east-west to its peak at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south.

Dun Laoghaire Harbour on the southside of the Bay has an East and West Pier, each one kilometre long; this is one of the largest human-made harbours in the world. There also piers or walls at the entrance to the River Liffey at Dublin city known as the Great North and South Walls. Other harbours on the Bay include Bulloch Harbour and Coliemore Harbours both at Dalkey.

There are two marinas on Dublin Bay. Ireland's largest marina with over 800 berths is on the southern shore at Dun Laoghaire Harbour. The other is at Poolbeg Yacht and Boat Club on the River Liffey close to Dublin City.

Car and passenger Ferries operate from Dublin Port to the UK, Isle of Man and France. A passenger ferry operates from Dun Laoghaire Harbour to Howth as well as providing tourist voyages around the bay.

Dublin Bay has two Islands. Bull Island at Clontarf and Dalkey Island on the southern shore of the Bay.

The River Liffey flows through Dublin city and into the Bay. Its tributaries include the River Dodder, the River Poddle and the River Camac.

Dollymount, Burrow and Seapoint beaches

Approximately 1,500 boats from small dinghies to motorboats to ocean-going yachts. The vast majority, over 1,000, are moored at Dun Laoghaire Harbour which is Ireland's boating capital.

In 1981, UNESCO recognised the importance of Dublin Bay by designating North Bull Island as a Biosphere because of its rare and internationally important habitats and species of wildlife. To support sustainable development, UNESCO’s concept of a Biosphere has evolved to include not just areas of ecological value but also the areas around them and the communities that live and work within these areas. There have since been additional international and national designations, covering much of Dublin Bay, to ensure the protection of its water quality and biodiversity. To fulfil these broader management aims for the ecosystem, the Biosphere was expanded in 2015. The Biosphere now covers Dublin Bay, reflecting its significant environmental, economic, cultural and tourism importance, and extends to over 300km² to include the bay, the shore and nearby residential areas.

On the Southside at Dun Laoghaire, there is the National Yacht Club, Royal St. George Yacht Club, Royal Irish Yacht Club and Dun Laoghaire Motor Yacht Club as well as Dublin Bay Sailing Club. In the city centre, there is Poolbeg Yacht and Boat Club. On the Northside of Dublin, there is Clontarf Yacht and Boat Club and Sutton Dinghy Club. While not on Dublin Bay, Howth Yacht Club is the major north Dublin Sailing centre.
