| Abstract | For decades the oil and gas industry in Vietnam has made the most important contribution to the development of Vietnam. The growth of petroleum industry leads to big demands on consh·uction of oil and gas facilities, many of which are now being built or planned to be developed all over the counhy, especially in the coastal areas in Southern Vietnam, where the main oil fields are being exploited offshore. The oil and gas conshuction projects in Southern Vietnam are highly exposed to risks, for which the ve1y soft clay deposit underneath takes a big share of responsibility. Differential settlement underlying soft clay have created a Jot of problems. It is recognized that, the rapid expansion of oil and gas consh·uction projects is not matching at all with the local level of geotechnical investigation, testing and analysis that are needed. In this study, development of the oil and gas facilities in Southern Vietnam was analyzed from the geotechnical point of view with reference to the risks caused by underlying soft clay deposits. One of important works of this study was to collect geological, hydrogeological and geotechnical data in pa1ticular to built up an initial database of Mekong soft clays in order to find out the dish"ibution and variation of the thickness of this soft clay layer. From the available geotechnical data at the Thi Vai Condensate Processing Plant (CPP) and Ca Mau Gas-Power-Fertilizer Indush·ial Park (GPF) sites, a detailed soil characterization was done to evaluate the soil characteristics at these particular sites. An significant output of this study was performance of an elech·ic imaging line to successfully map the soft clay deposits at GPF site for the first time. From the soil characterization results, differential settlement at the CPP site was analyzed to explain the damages at this site. |
