TechWorks Marine, a leading marine data company based in Dublin has recently announced a significant contract worth €475,000 with the European Space Agency (ESA). The contract aims to expand the use of satellite data and products in Europe's renewable wind energy sector.

In light of Irish wind energy supplying a record 43% of all electricity in Ireland in March, TechWorks Marine says it is taking the lead on a project to identify the current information needs and best practices for utilizing satellite earth observation products in the wind energy sector. As a pioneer in earth observation products in Ireland, TechWorks Marine will collaborate with key stakeholders to establish how earth observation-derived information products can be effectively used in the wind industry's business processes. The project is of strategic importance to both Ireland and Europe and is expected to result in the development of a best practices guide for companies to identify suitable sites for new wind farms, gain a deeper scientific understanding of site conditions, and enable precise environmental compliance and monitoring activities.

Commenting on the project launch, Charlotte O’Kelly, Managing Director of TechWorks Marine, emphasised the company's extensive experience in the renewables sector and expressed the value of using satellite data to aid in both onshore and offshore site development throughout the entire life cycle of wind parks.

Furthermore, Dr. Zoltan Bartalis, Earth Observation Applications Engineer at the European Space Agency, acknowledged TechWorks Marine’s expertise in advocating for increased satellite data usage and emphasized the importance of consolidating the usage of satellite-based Earth Observation information for wind energy applications.

This project comes at a timely moment, as Dublin is set to host the Wind Europe Technology Workshop 2024 in early June. The event will bring together over 450 wind energy experts from across Europe to discuss the latest innovations and challenges within the sector.

With a solid track record in earth observation and marine data products, including eight contracts from the European Space Agency, TechWorks Marine continues to make significant strides in advancing the renewable energy sector.

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.

#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".

Dublin Bay 21s

An exciting new project to breathe life into six defunct 120-year-old Irish yachts that happen to be the oldest intact one-design keelboat class in the world has captured the imagination of sailors at Ireland's biggest sailing centre. The birthplace of the original Dublin Bay 21 class is getting ready to welcome home the six restored craft after 40 years thanks to an ambitious boat building project was completed on the Shannon Estuary that saved them from completely rotting away.

Dublin Bay 21 FAQs

The Dublin Bay 21 is a vintage one-design wooden yacht designed for sailing in Dublin Bay.

Seven were built between 1903 and 1906.

As of 2020, the yachts are 117 years old.

Alfred Mylne designed the seven yachts.

The total voting population in the Republic's inhabited islands is just over 2,600 people, according to the Department of Housing.

Dublin Bay Sailing Club (DBSC) commissioned the boat to encourage inexpensive one-design racing to recognise the success of the Water Wag one-design dinghy of 1887 and the Colleen keelboat class of 1897.

Estelle built by Hollwey, 1903; Garavogue built by Kelly, 1903; Innisfallen built by Hollwey, 1903.; Maureen built by Hollwey, 1903.; Oola built by Kelly, 1905; Naneen built by Clancy, 1905.

Overall length- 32'-6', Beam- 7'-6", Keel lead- 2 tons Sail area - 600sq.ft

The first race took place on 19 June 1903 in Dublin Bay.

They may be the oldest intact class of racing keelboat yacht in the world. Sailing together in a fleet, they are one of the loveliest sights to be seen on any sailing waters in the world, according to many Dublin Bay aficionados.

In 1964, some of the owners thought that the boats were outdated, and needed a new breath of fresh air. After extensive discussions between all the owners, the gaff rig and timber mast was abandoned in favour of a more fashionable Bermudan rig with an aluminium mast. Unfortunately, this rig put previously unseen loads on the hulls, resulting in some permanent damage.

The fleet was taken out of the water in 1986 after Hurricane Charlie ruined active Dublin Bay 21 fleet racing in August of that year. Two 21s sank in the storm, suffering the same fate as their sister ship Estelle four years earlier. The class then became defunct. In 1988, master shipwright Jack Tyrrell of Arklow inspected the fleet and considered the state of the hulls as vulnerable, describing them as 'still restorable even if some would need a virtual rebuild'. The fleet then lay rotting in a farmyard in Arklow until 2019 and the pioneering project of Dun Laoghaire sailors Fionan De Barra and Hal Sisk who decided to bring them back to their former glory.

Hurricane Charlie finally ruined active Dublin Bay 21 fleet racing in August 1986. Two 21s sank in the storm, suffering the same fate as a sister ship four years earlier; Estelle sank twice, once on her moorings and once in a near-tragic downwind capsize. Despite their collective salvage from the sea bed, the class decided the ancient boats should not be allowed suffer anymore. To avoid further deterioration and risk to the rare craft all seven 21s were put into storage in 1989 under the direction of the naval architect Jack Tyrrell at his yard in Arklow.

While two of the fleet, Garavogue and Geraldine sailed to their current home, the other five, in various states of disrepair, were carried the 50-odd miles to Arklow by road.

To revive the legendary Dublin Bay 21 class, the famous Mylne design of 1902-03. Hal Sisk and Fionan de Barra are developing ideas to retain the class's spirit while making the boats more appropriate to today's needs in Dun Laoghaire harbour, with its many other rival sailing attractions. The Dublin Bay 21-foot class's fate represents far more than the loss of a single class; it is bad news for the Bay's yachting heritage at large. Although Dún Laoghaire turned a blind eye to the plight of the oldest intact one-design keelboat fleet in the world for 30 years or more they are now fully restored.

The Dublin Bay 21 Restoration team includes Steve Morris, James Madigan, Hal Sisk, Fionan de Barra, Fintan Ryan and Dan Mill.

Retaining the pure Mylne-designed hull was essential, but the project has new laminated cold-moulded hulls which are being built inverted but will, when finished and upright, be fitted on the original ballast keels, thereby maintaining the boat’s continuity of existence, the presence of the true spirit of the ship.

It will be a gunter-rigged sloop. It was decided a simpler yet clearly vintage rig was needed for the time-constrained sailors of the 21st Century. So, far from bringing the original and almost-mythical gaff cutter rig with jackyard topsail back to life above a traditionally-constructed hull, the project is content to have an attractive gunter-rigged sloop – “American gaff” some would call it.

The first DB 21 to get the treatment was Naneen, originally built in 1905 by Clancy of Dun Laoghaire for T. Cosby Burrowes, a serial boat owner from Cavan.

On Dublin Bay. Dublin Bay Sailing Club granted a racing start for 2020 Tuesday evening racing starting in 2020, but it was deferred due to COVID-19.
Initially, two Dublin Bay 21s will race then three as the boat building project based in Kilrush on the Shannon Estuary completes the six-boat project.
The restored boats will be welcomed back to the Bay in a special DBSC gun salute from committee boat Mac Lir at the start of the season.
In a recollection for Afloat, well known Dun Laoghaire one-design sailor Roger Bannon said: "They were complete bitches of boats to sail, over-canvassed and fundamentally badly balanced. Their construction and design was also seriously flawed which meant that they constantly leaked and required endless expensive maintenance. They suffered from unbelievable lee helm which led to regular swamping's and indeed several sinkings.
