C-Surveyor I Completes BHP ‘Shenzi’ AUV Survey

C & C Technologies’ deepwater AUV, C-Surveyor I, recently completed a hazard survey for BHP’s Sheniz project in Green Canyon. The scope of work required high-resolution multi-beam, sub-bottom and side scan sonar data in water depths ranging from 4,100 feet to 4,550 feet. During the project, the AUV collected over 1200 kilometres of survey line data that was analysed by onboard route engineers for QA/QC measures.
Since becoming operational in January 2001, the C-Surveyor I AUV has performed more than 40,000 kilometres of surveys on 72 different projects for government agencies and the oil and gas industry. The water depths for these projects range from 100 to 2850 metres and encompass different levels of complexity. Some of the more high profile projects have been locating historical World War II shipwrecks, performing pipeline investigation surveys and surveying through a full-scale production FPSO location.
