Onshore co-mining project, Lelydorp

Suralco L.L.C., an indirect joint subsidiary of Alcoa Inc. and Alumina Ltd., has awarded Boskalis a contract for the mining of bauxite in Lelydorp, Suriname. Boskalis is responsible for the entire mining process, from engineering and overburden removal to bauxite mining and ore delivery.

Mobilization

One of the most challenging operations of the project involved moving the Boskalis cutter suction dredger Orion from Abu Dhabi to the heart of the Surinam jungle. Overcoming bad weather and numerous engineering challenges, Boskalis managed to complete this job safely.

Wet overburden stripping

The Orion removed the wet overburden – consisting of both soft and stiff clays – prior to the mining operations.

Dry overburden stripping and mining

When the dredging has finished, the remaining overburden will be removed by our dry earth movement fleet, which consists of hydraulic excavators, articulated dump trucks and auxiliary equipment. Our earthmoving expertise means we will execute the entire production process from pit to plant. This includes activities such as fine stripping, ore sampling, drilling & blasting, ore haulage and ROM pad management.

Engineering and surveying

The wet overburden removal is charted using hydrographic single beam measurements; the dry excavation of overburden and mining progress is meticulously monitored by state of the art techniques such as UAV-photogrammetric and laser-scanning surveys.

Cieg GJ1 Cable repair

Channel Islands Electricity Grid, a joint venture between Jersey Electricity and Guernsey Electricity operate several interconnecting power cable systems (power and telecom) between Jersey, Guernsey and France. Both Jersey and Guernsey rely upon the services of these interconnecting power cables and as a consequence there is a demand to reduce the possible effects and impact of failure to these interconnecting power cables. Boskalis were contracted to conduct a preemptive repair replacing a section of cable including the installation two subsea joints on the Guernsey Jersey circuit, close to Havelet bay.
