This research evaluates the thermal performance of an industrial heatexchanger for process in the offshore industry. Steady state monitoring andperformance data were collected from 3-E-401 heat exchanger in an offshoreenvironment. Design and off-design evaluation was carried out using capacityratio, effectiveness, Log Mean Temperature Difference LMTD, heat duty, andoverall heat transfer coefficient as performance indicators. Three scenarioswere presented and Hysys® V8.7 software was used to model theprocess. The results showed that the best thermal performance of the heatexchanger in terms of capacity ratio, effectiveness, heat duty, LMTD, andoverall heat transfer coefficient is 94%, 85.5%, 88%, 88.7% and 71%respectively, of the design values. This best performance was reached at 9.9%fouling and heat loss reduction in the heat exchange process. An increase infouling and heat loss gradually reduced the thermal performance of the heatexchanger. Therefore a proactive maintenance action and condition monitoring inevery eight weeks is required to sustain and improve the performance asevaluated.
