Short description
The East West Interconnector (EWIC) is a high-voltage direct current (HVDC) interconnector which links the electricity transmission grids of Ireland and Great Britain. It has a power rating of 500 MW and utilises HVDC Voltage Source Converter technology. EWIC is a fully regulated interconnector which was developed and is owned by EirGrid Interconnector DAC (EIDAC) which is part of the EirGrid Group. The asset was built by ABB and entered into commercial operationa in December 2012. The asset base consists of the following;
In relation to the 187km of Marine Cable, EIDAC intend to undertake an ‘inspection survey’, comprising high resolution multibeam echo sounder and side scan sonar to assess the burial condition of the cable and identify any changes to the cable’s current protection and environmental conditions.

Description of the procurement
The East West Interconnector (EWIC) is a high-voltage direct current (HVDC) interconnector which links the electricity transmission grids of Ireland and Great Britain. It has a power rating of 500 MW and utilises HVDC Voltage Source Converter technology. EWIC is a fully regulated interconnector which was developed and is owned by EirGrid Interconnector DAC (EIDAC) which is part of the EirGrid Group. The asset was built by ABB and entered into commercial operationa in December 2012. The asset base consists of the following;
- 500 MW Converter Station (Portan, Ireland)
- 500 MW Converter Station (Shotton, GB)
- High Voltage Cable Spares Facility
- 40km HVDC Land Cable in Ireland
- 30km HVDC Land Cable in GB
- 187km HVDC Marine Cable
- 257km Fibre Optic Cable (bundled with cable)
In relation to the 187km of Marine Cable, EIDAC intend to undertake an ‘inspection survey’, comprising high resolution multibeam echo sounder and side scan sonar to assess the burial condition of the cable and identify any changes to the cable’s current protection and environmental conditions.
This survey follows on from the 2015 survey, wherein EIDAC performed a high-resolution survey to establish the cable depth of burial and seabed level dataset along the entire EWIC route. While the entire depth of burial survey will not need to be repeated, the proposed ‘inspection’ survey shall identify with confidence changes in sediment depth/mobility and the depth of burial/cable exposure.
