Erebus Geotechnical Survey UPDATE

Update: Please note the geotechnical works described in the NtM issued on the 27th March / 19th April 2023 (reference: Erebus/002 v001 Nearshore Geotech) regarding West Angle Bay are now complete and the Aran 120 has been demobilised to Pembroke Port.

The remaining work for this survey is currently underway on the export cable and array area, having started on the 19th April 2023. The work will be undertaken by the vessels Voe Vanguard and Fugro Scout operated by the survey contractor – Fugro. Vessel details are provided below.

These additional surveys are anticipated to occur in two phases; the first phase lasting for an approximate duration of between 10-14 days with the Voe Vanguard undertaking works estimated to start from the 19th of April 2023. The second phase will utilise the vessel Fugro Scout, with works expected to start on the 29th of April 2023. These timings are weather dependent and may be subject to change.

During the survey campaign, vessels will be deploying underwater Cone Penetration Test / Vibrocore equipment / rotary borehole drilling. During these times the vessels will have restricted ability to manoeuvre and therefore all other vessels are requested to fully comply with COLREGS obligations in respect of this.
