It’s not the first time, and hopefully not the last, that Van Tunen can be found in Castletownbere in Ireland. A beautiful fisherman’s town with a harbour that needs to be expanded. The complete work for this extension consists of building a 216m long quay structure, 66m long combi wall, dredging the mooring side next to the new quay extension, building new breakwaters.
The major challenge in this area is the hard rocks at the bottom of the port area. This of course requires a skilful technical solution. Together with Saes International, supplier of demolition equipment for machines such as ours, we looked into the feasibility of this challenging job.
An Epiroc HB7000 hammer was chosen, with a weight of over 7 tons, in combination with our Caterpillar 390 triple boom configuration. With good success we helped Keating Construction to dredge a solid rock at depths of -16/-18 meters.
