TechWorks Marine has commenced a comprehensive year-long metocean survey in Maritime Area A – Tonn Nua, of the Irish Government’s South Coast Designated Maritime Area Plan (SC-DMAP), supporting EirGrid’s Powering Up Offshore South Coast project.
Commissioned by Fugro, EirGrid’s appointed marine survey supplier, the survey will deliver vital baseline oceanographic and environmental data to support the development of offshore substations and grid connections along Ireland’s south coast.
This flagship initiative aims to connect 900 MW of offshore wind generation to Ireland’s power network, accelerating national progress toward the government’s target of 80% renewable energy and at least 5 GW of offshore wind in the coming years.. The Tonn Nua site is a designated area for spatially planned offshore wind, selected for its pivotal role in achieving Ireland’s climate action goals and enhancing energy security for nearly a million homes.
TechWorks Marine, the leading Irish-based supplier to Fugro on Powering Up Offshore South Coast, brings over 20 years of specialist expertise in metocean data collection and analysis. The data gathered will help inform the design and delivery of robust infrastructure for clean energy and support regional economic development.
Charlotte O’Kelly, CEO of TechWorks Marine, commented: “We are delighted to support EirGrid and Fugro on this landmark project for Ireland’s energy transition. Our team is committed to delivering world-class oceanographic data that underpins a resilient, sustainable, renewable energy system on the south coast.”
Speaking about the 2025 survey campaign, Chief Transformation, Technology and Offshore Officer at EirGrid, Liam Ryan, said:
“These surveys would not be possible without a huge amount of coordination and strategic planning of staff across EirGrid, our strategic partners, fishing communities and local landowners. The data being gathered from this research is essential in shaping plans for the installation of this transmission infrastructure for offshore wind and creating a cleaner energy future for Ireland.”
