Techworks Marine is deploying three surface buoys with single-point moorings for a metocean survey campaign at the site of the proposed Clogherhead Offshore Wind Farm.

It follows a geophysical survey campaign conducted by Alpha Marine this past summer, as previously reported on Afloat.ie.

These deployments are expected to be completed over a two-day period, at the next available weather window from Sunday 6 November, subject to weather and operational constraints.

Once deployed, the met ocean devices will remain on site for a period of up to 12 months.

The survey campaign will be undertaken within the proposed Clogherhead Offshore Wind Farm site, located some 10km from the Co Louth coast. Detailed coordinates and a map of the survey area are included in Marine Notice No 76 of 2022, attached below.

Three yellow buoys will be deployed, each with a hull diameter of 1.2m and a nominal freeboard of 0.7m. The buoys will display a St Andrew’s Cross day mark, and are fitted with a radar reflector and navigation light with a three nautical mile range, flashing a sequence of five flashes every 20 seconds.

Deployment operations will be conducted by the twin-hulled multi-cat work vessel MPV Skua (callsign 2GDE3).

During works, the vessel will be restricted in its ability to manoeuvre so all other vessels are requested to leave a wide berth during the deployment operations. Radio transmissions will be conducted with other seafarers to notify them of the operations.

TechWorks Marine plans to deploy four trawl-resistant bottom mounted acoustic Doppler current profilers (ADCP) frames in Castlemaine and Valentia off the coast of Co Kerry from this Monday 7 February.

Weather permitting, the Ocean Navigator (callsign EI018) will deploy the four trawl-resistant, bottom-mounted ADCPs frames — each of around one square metre in area — on the seabed for a minimum of one month and a maximum of two months, between this week and Monday 21 February.

They will be used to carry out water quality sampling surveys as well as vessel-mounted ADCP surveys at the same time as the deployments and these are tide and weather dependent and may cause a slight delay in the recovery of the seabed frames.

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

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. Throughout operations, the Ocean Navigator will be displaying appropriate lights and shapes.

Details of the exact locations of the ADCP frames and other information for mariners are included in Marine Notice No 08 of 2022, which can be downloaded below.

TechWorks Marine has scheduled the deployment of three trawl-resistant acoustic Doppler current profilers (ADCPs) in Tralee Bay from next week.

The three bottom-mounted ADCP frames will be positioned on the seabed at various depths between Monday 1 and Saturday 13 November, weather depending.

If the deployment is delayed due to unsuitable conditions, then it will be carried out on the next viable tide and weather window.

Once deployed, the frames will be on the seabed for a minimum of one calendar month and a maximum of two months, weather permitting.

They are required to carry out water quality sampling surveys and vessel-mounted ADCP surveys at the same time as the deployments. As these are tide and weather dependent, they may cause a slight delay in the recovery of the seabed frames.

The frames will be deployed by the Whispering Hope (callsign EIAR8) which will be restricted in its ability to manoeuvre during this operation.

Vessels operating within this area are requested to keep their distance, maintaining a safety zone around the deployment vessel, and pass at minimum speed to reduce vessel wash.

Details of the exact locations of the ADCP frames and other information for mariners can be found in Marine Notice No 59 of 2021, which can be downloaded below.

TechWorks Marine advises that it is set to deploy two marine monitoring buoys in Tralee Bay as part of environmental oceanographic monitoring for Fenit Harbour.

The DB 500 data buoys will be deployed tomorrow, Friday 26 March, weather depending, and will be in place until at least Friday 30 April, after which they will be retrieved by a chartered vessel.

A flat-bottomed aqua-cultural work barge named the Kerry Pearl will be deploying the buoys. During deployment and recovery, VHF Channels monitored will be Channel 14 (Fenit Harbour working channel) and Channel 16.

During the extent of deployment, vessel traffic will need to avoid the area.

Full details including exact location coordinates are included in Marine Notice No 14 of 2021, which can be downloaded below.

Published in Irish Harbours

TechWorks Marine has scheduled the deployment of a wave buoy off the coast of Wicklow on Tuesday 8 December, weather allowing.

The buoy will be a yellow DB 500 and have a flashing light sequence of five flashes every 20 seconds, with a range of three nautical miles. The buoy will be marked with a St Andrew’s sross and radar reflector.

The wave buoy will be deployed at 53° 2' 35” N, -5° 41' 17” W by the the AMS Retriever (Callsign MEHI8) with an AIS system on board which has a provisional callsign of CWPW01.

If the deployment is delayed due to the weather, it will be carried out on the next viable tide and weather window. Once deployed, the wave buoy will remain on site for a minimum of six months.

Further details can be found in Marine Notice No 57 of 2020, a PDF of which is available to download below.

The Department of Transport, Tourism and Sport has been advised by TechWorks Marine that the lantern on the monitoring buoy in Killybegs Harbour has stopped working.

The buoy is part of environmental oceanographic monitoring for the Department of Agriculture, Food and the Marine in a project that began last September, and can be found at 54° 37.03' N, 008° 26.40' W.

The buoy is deployed on a dual mooring. Two small marker buoys indicate the locations of each of the buoy’s moorings. Vessel traffic will need to avoid this area.

The lantern will be repaired as soon as possible on the next viable tide and weather window. For further information contact TechWorks Marine at 01 236 5990.

#MARINE SCIENCE - An Irish marine science company will lead a new research project using satellites to monitor coastal outlets in Europe, as Silicon Republic reports.

TechWorks Marine, based in Dun Laoghaire, has won the contract to head up the European Space Agency's earth observation project in what is a first for any Irish company.

The business specialises in real-time marine data platforms, and in this project will be using its expertise to assist operators and developers of water treatment plants to help reduce their impact on the environment.

A main focus of the observation research will be the coastal effect of wastewater treatment in Donegal Bay.

TechWorks Marine MD Charlotte O'Kelly told Silicon Republic that improvements in sensor technology have prompted the development of satellite imagery of a high enough resolution to allow for close monitoring of coastal activity even from earth orbit.

Minister of State for Research and Innovation Sean Sherlock said the contract "clearly indicates that Irish SMEs have the capability and expertise to lead projects in this highly competitive sector".

Marine Protected Areas (MPAs) - FAQS

Marine protected areas (MPAs) are geographically defined maritime areas where human activities are managed to protect important natural or cultural resources. In addition to conserving marine species and habitats, MPAs can support maritime economic activity and reduce the effects of climate change and ocean acidification.

MPAs can be found across a range of marine habitats, from the open ocean to coastal areas, intertidal zones, bays and estuaries. Marine protected areas are defined areas where human activities are managed to protect important natural or cultural resources.

The world's first MPA is said to have been the Fort Jefferson National Monument in Florida, North America, which covered 18,850 hectares of sea and 35 hectares of coastal land. This location was designated in 1935, but the main drive for MPAs came much later. The current global movement can be traced to the first World Congress on National Parks in 1962, and initiation in 1976 of a process to deliver exclusive rights to sovereign states over waters up to 200 nautical miles out then began to provide new focus

The Rio ‘Earth Summit’ on climate change in 1992 saw a global MPA area target of 10% by the 2010 deadline. When this was not met, an “Aichi target 11” was set requiring 10% coverage by 2020. There has been repeated efforts since then to tighten up MPA requirements.

Marae Moana is a multiple-use marine protected area created on July 13th 2017 by the government of the Cook islands in the south Pacific, north- east of New Zealand. The area extends across over 1.9 million square kilometres. However, In September 2019, Jacqueline Evans, a prominent marine biologist and Goldman environmental award winner who was openly critical of the government's plans for seabed mining, was replaced as director of the park by the Cook Islands prime minister’s office. The move attracted local media criticism, as Evans was responsible for developing the Marae Moana policy and the Marae Moana Act, She had worked on raising funding for the park, expanding policy and regulations and developing a plan that designates permitted areas for industrial activities.

Criteria for identifying and selecting MPAs depends on the overall objective or direction of the programme identified by the coastal state. For example, if the objective is to safeguard ecological habitats, the criteria will emphasise habitat diversity and the unique nature of the particular area.

Permanence of MPAs can vary internationally. Some are established under legislative action or under a different regulatory mechanism to exist permanently into the future. Others are intended to last only a few months or years.

Yes, Ireland has MPA cover in about 2.13 per cent of our waters. Although much of Ireland’s marine environment is regarded as in “generally good condition”, according to an expert group report for Government published in January 2021, it says that biodiversity loss and ecosystem degradation are of “wide concern due to increasing pressures such as overexploitation, habitat loss, pollution, and climate change”.

The Government has set a target of 30 per cent MPA coverage by 2030, and moves are already being made in that direction. However, environmentalists are dubious, pointing out that a previous target of ten per cent by 2020 was not met.

Conservation and sustainable management of the marine environment has been mandated by a number of international agreements and legal obligations, as an expert group report to government has pointed out. There are specific requirements for area-based protection in the EU Marine Strategy Framework Directive (MSFD), the OSPAR Convention, the UN Convention on Biological Diversity and the UN Sustainable Development Goals. 

Yes, the Marine Strategy Framework directive (2008/56/EC) required member states to put measures in place to achieve or maintain good environmental status in their waters by 2020. Under the directive a coherent and representative network of MPAs had to be created by 2016.

Ireland was about halfway up the EU table in designating protected areas under existing habitats and bird directives in a comparison published by the European Commission in 2009. However, the Fair Seas campaign, an environmental coalition formed in 2022, points out that Ireland is “lagging behind “ even our closest neighbours, such as Scotland which has 37 per cent. The Fair Seas campaign wants at least 10 per cent of Irish waters to be designated as “fully protected” by 2025, and “at least” 30 per cent by 2030.

Nearly a quarter of Britain’s territorial waters are covered by MPAs, set up to protect vital ecosystems and species. However, a conservation NGO, Oceana, said that analysis of fishing vessel tracking data published in The Guardian in October 2020 found that more than 97% of British MPAs created to safeguard ocean habitats, are being dredged and bottom trawled. 

There’s the rub. Currently, there is no definition of an MPA in Irish law, and environment protections under the Wildlife Acts only apply to the foreshore.

Current protection in marine areas beyond 12 nautical miles is limited to measures taken under the EU Birds and Habitats Directives or the OSPAR Convention. This means that habitats and species that are not listed in the EU Directives, but which may be locally, nationally or internationally important, cannot currently be afforded the necessary protection

Yes. In late March 2022, Minister for Housing Darragh O’Brien said that the Government had begun developing “stand-alone legislation” to enable identification, designation and management of MPAs to meet Ireland’s national and international commitments.

Yes. Environmental groups are not happy, as they have pointed out that legislation on marine planning took precedence over legislation on MPAs, due to the push to develop offshore renewable energy.

No, but some activities may be banned or restricted. Extraction is the main activity affected as in oil and gas activities; mining; dumping; and bottom trawling

The Government’s expert group report noted that MPA designations are likely to have the greatest influence on the “capture fisheries, marine tourism and aquaculture sectors”. It said research suggests that the net impacts on fisheries could ultimately be either positive or negative and will depend on the type of fishery involved and a wide array of other factors.

The same report noted that marine tourism and recreation sector can substantially benefit from MPA designation. However, it said that the “magnitude of the benefits” will depend to a large extent on the location of the MPA sites within the network and the management measures put in place.
