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.

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".

Silicon Republic has much more on the story HERE.
