The continued expansion of E & P activities in deepwater has resulted in a growing demand for reliable ocean current measurements and criteria throughout the entire water column. To satisfy this demand there has been an increasing requirement for refinement of instrumentation, deployment systems and real time display and forecast software. This paper describes the approach of oil companies, a service company and an instrument manufacturer to these requirements and shows how the close collaboration of these organizations has resulted in optimizing the data available to the operational decision makers and engineers. The paper discusses the developments in instrument technology, both hardware and firmware, optimization of data through system deployment approaches and the development of software appropriate for the offshore oil and gas industry. Examples of floating structure, drilling rig and riser (BOP stack) deployed systems are presented, together with recorded data sets. Considerations in deployment configuration and real time software and their impact on overall data quality are reviewed. Future requirements of the oil and gas industry in deep water are considered. In particular achieving full water column profiling capability in depths beyond 1,000m and enhancement of real time current prediction.
