Castletownbere Harbour

Overview

ABCO Marine (Irl) Ltd were contracted by Carillion Irishenco Ltd for dredging in relation to the Dinish Wharf new quay wall extension works. With the dredged material having to be dumped at sea, the Hebble Sand was utilised for both the loading and disposal. ABCO also mobilised a Modular Spud Barge with a Long Reach Excavator with GPS Dig System to support the dredge activities, the excavator was also used in the extraction of existing piles for the new quay construction.

The project had a number of different elements, including overwater piling from our C59 Emotion Jack-Up Barge supported from the shore by a crawler crane. Additionally we had dredging operations of the harbour, with all material loaded onto the Hebble Sand for disposal at sea. As part of the works existing harbour piling had to be removed, this was done both mechanically and also by ABCO Diver Ltd who had to underwater burning to remove piles at the design level.

Some 20,000m3 of material was dredged and disposed under a ‘Department of Agriculture, Fisheries and Food – Dumping at Sea Acts 1996 / 2004 Permit’.
