This geophysical, shallow geotechnical and environmental survey in the SNE field will help Cairn, and its joint venture partners, Woodside Energy, FAR and Petrosen, plan and engineer the facilities needed to develop the field for the West African country. Lloyd's Register has been contracted by Cairn to provide project management and technical assistance for the surveys, which are expected to be completed by September. 

Lloyd's Register employees will be focusing on ensuring optimum information on seabed and sub-seabed conditions are used to enable facilities to be designed safely and efficiently, and investigating relevant seabed areas and shallow soil zones, assessing the location for important marine life habitats. Additionally, the brief covers geotechnical site investigation to help Cairn develop a suitable subsea production system. This will involve drill centres connected via flowlines and umbilicals to a FPSO, as well as providing information on pipeline routes to get the oil and gas to shore.

Cairn and its joint venture partners received approval from the Senegalese government in 2015 for their evaluation plan, with Cairn going on to drill four further appraisal and exploration wells in the SNE field in the first half of 2016. Operators and the government hope that the discovery of hydrocarbons in Senegal will have a transformative effect across multiple industries.
