Objective

Analyze the technical feasibility of a SCR (Steel Catenary Riser) hanging an FPSO working Offshore Brazil, in a location 2800 m deep

Scope

  • The following analyzes have been performed in order to ensure the resistance of the riser:
  • o Calculation of the global stiffness matrix
    o Calculation of the wave induced motions of two-porch locations through seakeeping diffraction theory based on first order panel method
    o Generation of the time series of the displacements of the risers’ attachment points through a detailed FEM analysis (ANSYS)
    o Fatigue life
    o Estimation of the maximum stress
