Waterford: Where Tallships and Science Meet

Amongst the festival tallships lining Waterford quays, the RV Keary, a marine research survey vessel that mapped the estuary in advance of the tall ships arrival, will too be open to the public, writes Jehan Ashmore.

Work to map the navigational channel of Waterford Harbour's estuary was completed last month by the catamaran hulled craft that belongs to the Geological Survey of Ireland (GSI). Her smaller fleetmate the 7.5m RIB RV Geo carried-out work in the shallower areas along the river banks. For images of the seabed survey click HERE. The survey which had started in April was a joint research programme between (GSI) and the Marine Institute (MI).

This was the RV Keary's first INFOMAR survey leg of 2011 and it was also the first time that both vessels have worked in tandem. The mapping of the estuary was from an area just west of the city's Rice Bridge to the open sea at the mouth of Waterford Harbour.

The estuary was mapped before in 2007 using the Marine Institutes larger vessel the RV Celtic Voyager, which covered the harbour approaches from the 10m contour to greater depth offshore. Both RV Keary and RV Geo overlapped their coverage with this previous data, producing a comprehensive and seamless seabed map of the area.

RV Keary is constructed of marine grade aluminium and was custom built in 2008 for the (GSI) by Veecraft Marine of Capetown, South Africa.
The 15m craft with a draft of just 2m is equipped with an extensive range of highly sophisticated technology. She has an open working area at the aft-deck to conduct operations and is licensed to carry up to 12 personnel. For further vessel characteristics click HERE.

The 34-tonne craft made her 7,000 mile delivery voyage from the African continent to Europe. She was firstly transported on the deck of a cargoship to Rotterdam. After unloading at the Dutch port the 22-knot capable craft set off with several calls along the UK south coast to include loading bunkers before finally reaching Dun Laoghaire, from where she entered service in April 2009.

Offshore wind

ESB know the importance of offshore wind in tackling climate change and delivering net zero. Ireland has a unique capability given its prime location to take advantage of the potential of offshore wind. ESB are working hard to develop offshore wind projects for the benefit of everyone across society in Ireland and the UK. This includes ongoing engagement with marine users and local communities so ESB can deliver these significant projects.

Offshore wind will play a major role globally in our fight against climate change. It will help to replace energy generated by burning fossil fuels with that from a clean, safe and secure renewable energy source. Ireland’s geographic location on the exposed edge of the Atlantic presents us with a significant opportunity to generate electricity from wind – both offshore and onshore.

Power from onshore wind farms currently provide over one-third of Ireland’s electricity needs. But, whilst its marine area is many times the size of its landmass, Ireland’s offshore wind potential is only starting to be realised. ESB have a coastline stretching over 3,000km but only one operational offshore wind farm – Arklow Bank, with a capacity of 25 MW. In contrast, Belgium’s coastline is only 63km long, but it has already developed more than 2,000 MW of offshore wind. In Great Britain, with a coastline four times the length of ours, offshore wind generation now equates to over 440 Arklow Banks, with an installed capacity of 11,0000 MW as of late 2021.

The Irish Government's target to install 5,000 MW of offshore wind capacity in our maritime area by 2030 is set out in the Climate Action Plan 2021. It also has the objective to source 80% of Ireland’s electricity needs from renewables by the same year. In line with this, ESB is applying its professional and proven engineering expertise to the challenges set within the Climate Action Plan.

ESB are committed to playing a strong role in developing Ireland’s offshore wind potential for the benefit of the people of Ireland. This will be done in consultation with marine users and local communities, and with due care for the marine environment.
