摘要：
The outcome of a development project carried out at the Norwegian Geotechnical Institute (NGI) in close cooperation with the BAT Envitec company of Sweden to modify the onland BAT water monitoring system for offshore use, is briefly described. The equipment has been successfully tested (calibrated) onland and used in several offshore soil investigation projects. Different approaches to the interpretation of test results in terms of coefficient of permeability, gas content and hydraulic fracture pressure with some examples are presented.
