Connecting the grid over land and sea
In the specialized field of underground and underwater cable applications, we have technical and management experience in nearly every aspect of engineering and construction. We design and construct submarine and horizontal directional drilling cable projects, with experience delivering underground and submarine transmission at voltages from 115 kilovolts to 765 kilovolts.
Our work in projects such as the Greenlink Interconnector provided 500 megawatts of HVDC subsea and underground cable interconnection across the Irish Sea, connecting the grids of Ireland and the United Kingdom, increasing energy security and supplying clean power for thousands of homes and businesses.
Our engineering services support projects of all voltage levels and technologies, including high-voltage direct current (HVDC), extra-high voltage (EHV) and alternating current (AC) systems with a focus on interconnecting renewable energy into existing power grids to maximize clean energy potential.
