According to one of the UK's ports' operators, the Peel Ports Group say they have the capability to limit the impact (of Brexit) on the Britain's expected departure from the EU on 31 October which is expected to have on trading.

Among the ports of the Group are Liverpool, Heysham and Sheerness (London Medway) which have a combined capacity to handle 1 million RORO (roll on, roll off) units per year. The ports could play a vital role in ensuring cargo flow freely through UK ports as trade is expected to be challenging across the Dover Straits following Brexit.

The ports on the Irish Sea and on the Medway have already taken steps to improve resilience ahead of Brexit. These include increased throughput capacity for HGV trailers and storage to support smooth trade operations by roll-on roll-off (Ro-Ro) ferries.

Heysham has unrestricted access to the Irish Sea and already caters for numerous daily Ro-Ro sailing from providers including Seatruck, Stena Line and the Isle of Man Steam Packet.

Peel Ports says that transporting non-perishable freight unaccompanied is faster and more cost effective than relying on driver-accompanied hauliers - of whom there are an acute shortage of across the continent - to transport cargo from Europe to the UK and vice versa.

Routing via ports such as London Medway would be just as efficient as the existing options through the Dover Straits, as although the sea leg is longer, road miles are reduced, according to Peel Ports. They also added Door-to-door, cargo owners could reduce cost, increase resilience, avoid congestion and reduce carbon emissions.

A geohazard investigation to provide support for ongoing research at the Irish Centre for Research in Applied Geosciences (iCRAG) will be undertaken in the Irish Sea from Thursday 24 October until Wednesday 6 November, weather dependent.

The locations of these works at various shipwreck sites off the Louth coast are provided in Marine Notice No 41 of 2019. The equipment and techniques to be used include:

  • Surveying using multibeam echo sounders and shallow seismics (pinger);
  • Passive acoustic monitors (PAM) deployed at the indicated locations near the seabed to record acoustic data;
  • Seismic sparker equipment to reveal subsurface structure and features;
  • Sediment core taken at indicated locations to characterise the lithological characteristics of the seabed with grab samples taken within a 3nm range of these locations.

The surveys will be completed on a 24-hour schedule by the RV Celtic Voyager (callsign EIQN) which will display appropriate lights and signals.

Acoustic surveying using a multibeam echo sounder and seismic sub-bottom surveys using a sparker/pinger system will be performed during both day and night operations in accordance with safe operating practices regarding MMO procedures and cognisant of fishing gear.

Sediment sampling using cores will be carried out during daylight hours due to limited ship mobility. PAM units will be deployed and retrieved at both night and day as dictated by survey conditions.

Full details of the survey locations as well as contact information are included in Marine Notice No 41 of 2019, a PDF of which is available to read or download HERE.

Ferry operator Stena Line is currently engaging with freight customers on its Irish Sea routes to advise them of an important International Maritime Organisation (IMO) environmental regulation which will come into effect on 1st January 2020.

The goal of the Global Sulphur Cap 2020 Regulation is to significantly and progressively reduce sulphur emissions within all areas of international shipping and applies to all ship operators world-wide.

A number of regulations have been introduced over the past years aimed at making the shipping industry more environmentally friendly, such as the 2015 sulphur cap in the English Channel, North Sea and Baltic Sea. This new mandatory cap of 0.5% sulphur in ships’ fuel will now require all operators on the Irish Sea to ensure reduced emissions by switching to low sulphur fuels from 1st January 2020.

The new industry regulation will see operating costs increase outside of Stena Line’s control.

As a result, at the start of the new year all freight shipments on Stena Line’s Irish Sea routes will be subject to a higher fuel charge, in order to cover the additional costs incurred. Further details on these costs can be found on Stena Line’s freight website via this link.

The main lay installation works for the Rockabill Subsea Cable will take place from tomorrow, Saturday 20 July, to Sunday 1 September.

Using the vessel CS Teliri (callsign IBBT), the Rockabill cable system will be conducted from north of Lambay Island across the Irish Sea to Southport in England.

The cable itself is armoured and has an OD of 38mm. The cable ship will firstly clear the route of seabed debris with a grapnel before installing the cable.

During installation operations, the vessel will be moving slowly along the route while towing a sea plough to bury the cable into the seabed. During these works the vessel will have restricted manoeuvrability as it completes the work scope.

Deployed guard vessels will monitor the exposed areas of cable at crossing locations while burial progresses.

Ships are asked to avoid using anchors, bottom-trawl fishing and other seabed gear within half a mile of this cable route, and to maintain a safe distance from the cable ship during installation operations and that static gear be relocated from the route prior to commencement of operations.

Vessels are requested to pass at a safe speed and distance and fishing vessels are advised to remain a safe distance from the areas identified. Guard vessels will be deployed at certain cable crossing points to aid in monitoring the exposed areas and will advise of safe distances locally. The vessels will monitor VHF Channel 16 at all times.

The location co-ordinates of the operation are as included in Marine Notice No 24 of 2019, a PDF of which is available to read or download HERE.

TechWorks Marine Ltd is deploying trawl-resistant bottom mounted Acoustic Doppler Current Profiler (ADCP) frames in Waterford Harbour this week.

It is anticipated that the ADCPs will be deployed between today, Monday 8 July, and this Friday 12 July, depending on the weather. If the deployment is delayed due to the weather, it will be carried out on the next viable tide and weather window. Update: the ADCPs will now be deployed on or after Thursday 18 July.

The frames will be deployed from the vessel James (callsign EITT2). The frames will be on the seafloor for a minimum period of one calendar month and a maximum period of two months (weather permitting).

The ADCPs will be measuring currents through the water column at each location over the deployment. This data will be used to validate a hydrodynamic model of the area being developed for Irish Water.

Each frame will have one ADCP sensor, an acoustic pinger, an acoustic release and a rigid recovery buoy.

The frames are approximately 1m2 and will remain on the seafloor for a period of up to 30 days, after which the frame will be retrieved using the acoustic release and recovery buoy.

There will be no surface marker during the extent of deployment so vessel traffic will not need to avoid the area but should be aware of its presence.

Details of the relevant co-ordinates are included in Marine Notice No 22 of 2019, a PDF of which is available to read or download HERE.

Meanwhile, planned cable survey works on the EirGrid East West Interconnector are being carried out by the vessel Deep Helder (callsign PBYU) until this Thursday 11 July. During this survey, the vessel will be deploying underwater survey equipment along a thin 50m corridor.

Fishermen are advised not to leave any static fishing equipment in the vicinity of the survey route (250 metres) and keep a safe distance of at least one nautical mile from the survey vessels that will be operating with towed equipment and will have restricted manoeuvrability.

In addition, the survey vessel Ping will carry out operations in the near-shore waters off Rush, Co Dublin from next Monday 15 July. Near-shore survey operations will take place between beach HW mark and the 10m water depth contour.

Details of co-ordinates and survey contacts are included in Marine Notice No 21 of 2019, a PDF of which is available to read or download HERE.

The Irish Examiner writes that the Taoiseach has said that a no-deal Brexit would have a severe impact on the Holyhead/Dublin trade route.

Speaking at the 20th anniversary of the British-Irish Council (BIC) in Manchester, Leo Varadkar said Ireland would have to impose tariffs on goods entering the state from the UK.

“I think in the event of a no-deal Brexit, there would be a very severe impact on trade between Dublin and Holyhead,” he said.

“In the first instance, we would have to impose tariffs on all goods being imported into Ireland from the UK and we would have to put in place the necessary customs checks and controls, and we have the infrastructure in place at Dublin Port and the staff to do that but we really don’t want to do it.”

Likewise, First Minister of Wales Mark Drakeford said his government would prepare for all eventualities.

Departing Dublin Port last night was a small cruiseship when compared to the giants of the industry yet this caller is one of the most prolific visitors and on the Irish Sea this season, writes Jehan Ashmore.

The diminutive Corinthian of just 4,077 gross tonnage and a capacity of 110 guests had arrived from Douglas, Isle of Man from where the Maltese flagged vessel last month was among a quartet that formed a 'Week of Maidens' calls throughout Manx waters.

Prior to the Isle of Man, Corinthian called to Belfast Harbour as a regular and likewise in Dublin the Valletta registered ship has berthed on several occasions this season in the 'Docklands' quarter. This waterfront area once dominated by warehouses and cranes is now occupied by finance houses and appartments lining the Liffey quays between the city-centre and the Tom Clarke (East-Link) bridge.

With an overall draft of just 4m and 88m in length Corinthian easily made a transit of the bascule bridge and took a specific berth upriver along Sir John Rogersons Quay. Along this stretch is a legacy of the Dublin Docklands Development Authority which designated a south quay berth to encourage shipping activity to the quarter.

Instead of routine tea-time departures as typical of the majority of callers, Corinthian had spent a lenghtly stay. The Italian built ship launched for Renaissance Cruises and operated by subsequent owners until acquired by GCL in 2014 departed Dublin Port last night at 23.00hrs and made an overnight passage to Fishguard, Wales.

The port in Pembrokeshire operated by Stena Line Ports this year is scheduled for 33 callers, the majority of those will be carried out by Corinthian totalling 11 visits this season. Among these cruiseships so far to visit this scenic setting on the Pembrokeshire Coast National Park was Variety Voyager a vessel more akin to a private superyacht. 

Corinthian is scheduled to return to Dublin next week on Tuesday, July 2nd.

A series of ecological surveys will take place in the Irish Sea off the Dublin and Wicklow coast between now and May next year to provide data on seabirds and marine mammal species to inform the development of the Dublin Array Wind Farm.

The survey dates are weather dependent but will comprise a survey in each calendar month until May 2020, commencing tomorrow (Monday 24 June), with additional monthly surveys this August and September.

The location of the surveys will be off the Dublin and Wicklow coast in the vicinity of the Kish and Bray Banks. Surveys will be undertaken in daylight hours and each will usually be completed over a period of two days.

For the initial survey, the work vessel will not be towing survey equipment. During subsequent surveys the vessels may be towing a hydrophone up to 100m astern and will be restricted in their ability to manoeuvre. Vessels are requested to leave a wide berth.

Details of co-ordinates of the survey areas, and relevant work vessels, are included in Marine Notice No 18 of 2019, a PDF of which is available to read or download HERE.

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
