Geoscience Techniques for Engineering Assessment of Oman to India Pipeline Route

摘要

A variety of geoscience techniques were used to define soil conditions and evaluate geologic processes in order to develop design criteria for complex segments of the proposed Oman to India pipeline route. Geophysical survey data, seafloor cores, ROV observations of the seafloor, and oceanographic measurements were the principal field data collected. Geotechnical soil testing, and x-ray radiography, detailed geologic logging, and C-14 age dating of cores were carried out. The diverse sets of field data and lab test results were integrated by a multi-disciplined team of geoscientists and engineers to develop geologic and soil models, soil design criteria, a turbid flow model, and seafloor stability models. The integrated approach used here is applicable to other complex areas where seafloor stability needs to be assessed or design criteria need to be developed for active geologic processes.
