GDF Suez and Wintershall Inspection Surveys and Construction Support

In 2013 Pickworth Cartography was contracted by N-Sea Survey B.V. to assist with cartography and post-processing of data for their pipeline pre-lay surveys, debris inspection, and construction support of four different field locations in the Dutch Sector of the North Sea. The various fields ranged in depth from 19m to 40m, and the survey lengths ranged from 2.5km to 24.5km. Multibeam data was collected using a vessel mounted R2Sonic 2024 echosounder, and post-processed using QPS QINSy Validator and QLoud. Side scan sonar and sub-bottom data was collected using a towed Klein 3900. Cartography was done using AutCAD Map 2012.
