The Perch to the western side of the entrance to Glandore and Union Hall harbours, just north of Eve Island, had been damaged during a storm.

VTMS built the new system fully in-house in Leicester and undertook an installation which required no major plant such as for piling operations and caused minimum disturbance to both the rock and to harbour traffic.

The rock was only exposed for three to four hours per day at very low tides, which only occur once a fortnight. Keel Beg Pier is normally crowded with boats berthed as deep as six abreast but when the tide was right, VTMS had the large Carbery Isles Limited landing craft alongside for a procedure which involved first flattening the rock. This was followed by a drilling operation which included the insertion of four drilled stays. With the completed lights and aids to navigation installed, new navigation procedures for the area were able to come into effect.
