Gardline experience

 Geophysical, Geotechnical and Environmental data represents major areas of interest for Oil & Gas companies  Seabed Morfology, Soil Resistance and Habitat Assessments are key elements for subsea engineering and biodiversity studies and can be easily combined onto a single survey cruise  Multidisciplinary personnel + Multi Purpose vessels = cost effective soltuion
