Boskalis Westminster has completed installation of the gravel pre-load on the Cowes new breakwater as scheduled, having deposited a total of 51,000m3 to bring the crest of the gravel core up to between 3.7 and 4.4 meters above chart datum.
Five settlement beacons were also installed on the breakwater for on-going monitoring during a four to six week initial resting period prior to the gravel pre-load being reshaped up to 5.0m above chart datum this autumn; the settlement beacons will remain in place until spring 2015.
Boskalis has returned to the site, for approximately two weeks, to reshape the breakwater core using gravel stored on the breakwater sides; this will be achieved using an excavator and a floating spud-legged barge.
