Course Overview
This intensive Course will provide the attendee with a comprehensive overview of the many and varied activities that are involved in designing, constructing and maintaining onshore and offshore pipeline infrastructure to transport hydrocarbons in a cost effective manner.
The material is presented in a logical sequence covering Projects planning, hydraulic design, mechanical / geotechnical design, materials selection, construction, maintenance. Practical examples are used throughout and the lectures are supplemented by video presentations. Design problems and group projects are an integral part of this course.
