The objective of the project was to conduct the stress analysis of the nozzles of two shell and tube heat exchangers installed in a FPSO due to the high design loads. The mechanical design, static calculation of the nozzles as per WRC 537 and FEA analysis were carried out.

Through the analysis, the geometry and thicknesses of the components were determined in accordance with the design conditions. The analysis was carried out to the ASME VIII Div.1 code.
