Ten years ago, Kietta launched a project to develop a new method of marine seismic acquisition using midwater stationary cables and autonomous surface vehicles. We present the concept and the technology bricks and recount the successful performance of a commercial pilot survey. The objective of the technology is to enable flexible acquisitions and deliver high-quality, high-fidelity seismic data without sacrificing productivity. After reviewing existing marine seismic acquisition methods, we describe the technology development, including sea trials. The geophysical advantages of acquiring true 3D/four-component data are demonstrated by seismic data analysis, including simultaneous sources and associated productivity calculation.
