Floating Production Storage and Offloading (FPSO) in its operation is significantly affected by the environmental load as well as operational loads. These loads indirectly affect the structural components such as modules and its supports structures onboard of the FPSO. Investigation of fracture propagation has been carried out on the scantling support structure system of gas processing module. Modeling the structure with the finite element method (FEM) approach was performed by utilizing ANSYS 11.0 software. The fracture propagation evaluation is accomplished by elastic-plastic fracture mechanics with J-Integral method on crack first-mode (opening crack) accordance with DNV-OS-F201. As case study, FPSO Belanak operated at Conoco Block B in Natuna, Indonesia was investigated.
