Coastline completes vibrocoring for Hanson

The scope of the first works comprised 58 core locations off Norfolk UK. The specialist geotechnical survey vessel MV Flatholm was mobilised and the work was completed using Coastline’s high powered vibrocore, ‘C-Core-HP’, in 5m configuration. The average overall recovery was 4m.

The second works comprised of 70 core locations, spread over four licence areas, off Lincolnshire and North Norfolk, the furthest area being 27 miles off the North Norfolk coast. The work was completed port to port out of Lowestoft, in less than four days with an impressive average recovery of 4m completed by the experienced team onboard.

The favourable weather allowed the vessel to remain on site overnight throughout the works, without requirement to return to port each evening. Uniquely for a vessel of its size, this important ability reduces the likelihood of encountering poor weather (and therefore standby costs), maximises on-site time for the client and reduces unnecessary steaming and fuel consumption. The latter is an increasingly important issue with new larger, higher powered (therefore high fuel consumption) vessels entering the market.
