The project entails the laying of three pipelines for the disposal of treated effluent from the new Changi Water Reclamation Plant. The pipelines will be installed onshore and in a trench in the seabed.

The work assigned to Boskalis includes dredging a trench offshore, laying a rock mattress for the pipelines, installation of the pipelines (both ashore and offshore) and covering the pipelines with protective sand and rock.

Boskalis has also announced that it has acquired a large order in Nigeria, and says it plans to strengthen its position in the Netherlands with the acquisition of J van Vliet bv in Wormerveer.

The Nigerian order will see the company prepare a parcel of seabed for the construction of a 'gas to liquids plant' in Escravos, Delta State, Nigeria. The value of the contract exceeds ?110m, and the work will be executed using large and mid-size trailing suction hopper hoppers.

Boskalis says the work will take approximately 12 months to complete.

J van Vliet trades in sand for reclamation and is a civil contractor. The company holds a strong market position especially in the Amsterdam and the North Holland area. Turnover in 2001 was approximately ?10 million and the company employs 30 staff.

Boskalis says J Van Vliet will continue to operate under its existing name and with the current management.
