The oil and gas industry is facing a challenging business climate, therefore we need to be competitive yet innovative and show value year on year. This paper, and subsequent presentation, will give an insight into the type of surveys acquired, how competitive scoping is performed, new technology is applied and how (hydrographic) survey data is managed internally.
Efforts are being made to identify ways to further reduce costs for seabed survey projects: Workscopes are reduced, competitive rates are achieved by re-tendering or mini tendering contracts, combining surveys where possible by continuously engaging with assets and projects and working in collaboration with other operators for seabed surveys where feasible.
Surveys can be acquired more competitively by applying affordable new technology; as a result, survey requirements have been updated to account for high-resolution multibeam echo sounders and side-scan sonar and survey methodologies have been implemented to fit the area of interest. Additional deliverables such as multibeam backscatter are being used to help to make correct business decisions.
Survey deliverables are shared through the Seabed Survey Data Model (SSDM). The SSDM reduces the dependency on hard copy mapping and CAD deliverables and leverages the use of GIS and web-based mapping and as result, the acquired hydrographic data sets can be integrated with corporate data holdings.
