UK: Coastline Surveys Completes Pre-Dredge Vibrocore Survey in Portsmouth Harbour

Coastline Surveys Complete Pre-Dredge Vibrocore Survey in Portsmouth Harbour

Coastline Surveys Ltd has completed a major contract for a geotechnical survey and laboratory analysis in support of the MoD’s capital dredge campaign in Portsmouth Harbour. The programme is to support the 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.

David Hitchcock, Managing Director of Coastline Surveys Ltd, said “This is a major geotechnical survey and Coastline Surveys was awarded the contract despite fierce competition from much larger companies. This success highlights Coastline’s position in the market and its commitment to quality, customer service and dogged determination to deliver on time, on budget and with an excellent safety record”.
