Pre-dredge Vibrocore Survey

Coastline Surveys has completed a major contract for a geotechnical survey and laboratory analysis in support of the MoD's capital dredge campaign in Portsmouth Harbour, UK. The programme is to support an extensive upgrade and deepening of the channel. 

 

The pre-dredge geotechnical survey involved the acquisition of 174 vibrocore samples up to a maximum of 6m penetration depth. Coastline's multi-role survey vessel, MV FlatHolm, mobilised in early December and completed all field work activities in early 2012.

 

Coastline's soils laboratory in Lowestoft will undertake analysis, description, sub-sampling and advanced testing of the samples.
