Boskalis Keeps up Good Work in Cowes

Work on the new Cowes breakwater progresses extremely well with CHC’s contractors Boskalis Westminster currently on stage 4 of the 2014 programme, the installation of the breakwater’s gravel core up to approximately 4 meters above chart datum.

BoskalisThe dredger Sospan Dau delivers up to to five loads of gravel per day which is then sprayed onto the breakwater footprint via the floating pipeline and spray nozzle located on the D2 barge. The barge is secured with anchors and anchor wires that run to the extremities of the Exclusion Zone. A total of 40,000 cubic meters of gravel will be laid over a period of approximately four weeks.

On completion of this stage the breakwater will be visible at all times, apart from at spring high waters.

CHC has reminded all harbor users that the Cowes Breakwater Project construction programme is wholly contained within the Exclusion Zone which is marked by large, lit navigation buoys; any vessel not involved in the works shall remain outside of the Exclusion Zone at all times due to the presence of works equipment, obstructions and a growing gravel bank.

breakwater Construction ZoneThe breakwater Construction Zone has been extended into the area of small craft moorings to facilitate the required mooring arrangement for the D2 works barge when all mooring wires will be contained north of the breakwater. Two additional yellow marks have been deployed along the boundaries of the extension; an 80m section of floating pipeline has also been anchored on the eastern boundary of the Exclusion Zone.

Sensor installation

Two sensors have recently been inserted into the center of the breakwater; these log water pressure every 10 minutes. In order to allow for retrieval of the sensors they have been installed in plastic duct work.

After some four weeks the sensors will be removed and the data downloaded. This data will give Boskalis Westminster insight as to the amount of and speed of settlement in the breakwater’s gravel core. These two factors will allow Boskalis’ geotechnical engineers in the Netherlands to predict the final settlement and total settlement time for the breakwater.

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
