Development of A Model for Technical and Commercial Evaluation of Rotating Equipment for Offshore Plant

Heavy duty and safety requirements during the plant operation require the static and
rotating equipment specified for any operations fully meet the specification. As such the
design engineer has to carefully select the criteria to evaluate any equipment. The
current approach of evaluation is time consuming. In this project, research was done to
address this issue. At technical and commercial evaluation was developed for selection
of rotating equipment for offshore applications. The project focused on two methods
which were Pairwise Comparison and Factor Rating method by examining related
important criteria between available equipment. The Pairwise Comparison compared all
the important criteria of the equipment to get the weight of each criterion for factor
rating method. By using factor rating method, criteria were compared the ahernative
equipment in term of score thus the highest weighted score (weight rating x score) was
chosen as the best. Commercial evaluation model also been developed to enhance the
selection of the best alternatives in term of economical wise. Present Worth analysis was
used to develop the model. Microsoft Excel was used to illustrate a rough model
integrating all the mathematical equation, criteria and weight rating method to fmd
solution of the best ahernatives.
