Abstract
Summary
Magnetic investigate in offshore engineering survey are performed in order to search for local magnetic anomalies which can be potentially dangerous during construction of oil and gas facilities site. Proposed technology includes using of magnetic base station in order to obtain high accuracy of observations of differential hydromagnetic surveys. Comparison of processing results of magnetometric field data using magnetic base station and only gradiometer are shown. The work performed in order to make it possible to achieve low values of the root-mean-square error of hydromagnetic survey. Guidelines were developed for changing the methodology for carrying out this type of work
