Abstract:
A problem for the offshore oil and gas industry is
obtaining complete real-time current profiles in water depths
greater than 1200m, the present maximum range of a single RD
Instruments Acoustic Doppler Current Profiler (ADCP) meter.
Increasing commercial activity in those depths and the desire to
further understand deep ocean processes drives this need. A
solution that implements a two-meter system utilizing
underwater acoustic modems was developed. The study tested a
dual-meter system that integrated surface and bottom mounted
ADCP systems. The challenges addressed were uncertain
performance of the modems and the ADCPs due to the noisy
underwater acoustic environment and a potential lack of deep
water acoustic backscattering. The significant advantage of a
real-time data acquisition system is providing operational
guidance for the rig activities and the ability to control the
system in effort to optimize profiling range and performance.
