Port Maintenance Dredging Contract in Argentina
Royal Boskalis Westminster (The Netherlands) has been awarded a contract for capital and maintenance dredging in the port of Bahía Blanca, Argentina. The contract value is approximately EUR90 million and was acquired together with the Jan de Nul Group, Belgium. Boskalis' share of the total contract is approximately EUR55 million.
The project scope includes capital dredging and a five-year maintenance contract to maintain the depth. The capital dredging work will be performed in 2012, and 5.5 million cubic metres of firm soil will be removed with a large seagoing cutter suction dredger. This firm soil consists mainly of shale. The maintenance contract requires the annual removal of approximately 3.8 million cubic metres of silt over a period of five years and will be carried out with a trailing suction.
CSIRO from Australia is undertaking a survey tour towards the Australian Bight for a baseline survey looking for oil traces in the water. The surveyors are deploying a CTD and a gravity corer measuring possible traces of oil in the water column. The survey mission also consists of hydrographic mapping techniques, GIS and environmental specialists to make sure the situation before exploration is mapped well in order to know what the environmental consequences of an eventual oil seepage or leak may consist of.
