Through analysis of life-cycle costs, upstream facilities engineers can evaluate design alternatives such as turbine vs. motor driver selection and establish best practices for various types of facilities.The upstream oil and gas industry historically has focused primarily on equipment availability as a primary design input, which differs significantly from typical designs or operating strategies found in sectors operated on smaller margins, such as refining and chemicals.The analysis method discussed can benefit preappraise, appraise, and select project stages of a typical offshore development. The primary technique covered involves profiling various options with life-cycle analysis to d...
