Ireland, Dublin

Profile AWARD: Marine Survey - Cross-Shannon Cable Project. EirGrid have identified a requirement to procure a
marine survey contractor to carry out high-quality estuarine geophysical, geotechnical and benthic marine
surveys in the Shannon Estuary between Moneypoint in County Clare and Kilpaddoge in County Kerry along
with associated reporting. The approximate length of the estuary crossings which are the subject of this survey
is 3 kms. The seabed/estuary bed survey programme will be undertaken in order to enable optimal cable
engineering of a route viable for installation. High levels of renewable generation are currently being inte-
grated into the transmission and distribution systems in the South and West of Ireland. At times of high wind
generation output, it is expected that wind generation will displace conventional generation on the system in
order of economic merit, while respecting operational constraints. As a consequence of this, at times of high
wind, large bulk power flows are expected to flow from the West and Southwest towards the large load centres
on the East coast. A system reinforcement is required to facilitate these projected power flows, as well as to
resolve other network issues including voltage collapse, large phase angles and thermal issues. Part of the
system reinforcement required includes the development of the Moneypoint - Kilpaddoge 400 kV circuit.
This will involve the installation of an additional cross Shannon cable at 400kV between the existing sub-
stations at Moneypoint Co. Clare and Kilpaddoge Co. Kerry, as well as the installation of a new 400/220
kV transformer at Kilpaddoge substation. The survey will comprise of the following activities: Marine Geo-
physical Surveys, Marine Geotechnical Sampling and Laboratory Tests (following completion of the Marine Geophysical Surveys), Benthic Survey (may be required)
