 Hydrographic Survey – Cross-River pipeline

Northern Divers (Engineering) Ltd will conduct a cross-river hydrographic survey of a submerged gas pipeline on behalf of Gas Networks Ireland on the approaches to Limerick.  The pipeline is located downriver of the Limerick Tunnel (see chartlet attached).

The survey will include both a shoreline element and also the deployment of a RHIB to conduct the sub-surface survey.  The RHIB will deploy from further upstream at Limerick City.

The planned date is Saturday 10th December.  It is intended that RHIB and shoreside personnel will deploy on-site at approx. 0900hrs and that survey will be conducted close to Low Water (1241hrs that date).

The RHIB will maintain a listening watch on VHF Ch11 and VHF Ch16.  A designated lookout will also be posted to monitor any approaching traffic.

Further information is available via Marine Operations (069 – 73103) or the Duty Harbour Master (087 – 2542266).
A copy of the chartlet is attached.
