Samsung Heavy Industries operates the Geoje Shipyard, which is the largest shipyard in South Korea and boasts the highest dock turnover
rate in the world. Samsung Heavy Industries specializes in the building of special purpose vessels, such as LNG carriers, off-shore related
vessels, oil drilling ships, and floating production, storage, and off-loading (FPSO) vessels, including this USD 3 billion FPSO caisson and
support structure project.
Samsung Heavy Industries performed the strength analysis for the FPSO caisson and relevant structures using SACS, Bentley’s offshore
analysis and design software, as well as finite element method (FEM) analysis. Hydrodynamic loads extracted from SACS were applied to
the FEM model for support structure analysis. This hybrid modeling approach is used frequently on offshore projects.
The goal of this parametric study was to analyze the factors that affect the launching trajectory and bottom clearance during a jacket
launching. Samsung Heavy Industries had to check many issues, including barge mean draft, barge initial trim, buoyancy tank volume,
number of buoyancy tank compartments, mudmat area, and mudmat type.
SACS enabled the project team to check by changing the barge draft/trim, in which case there was no effect on bottom clearance or
relative velocity. By adding buoyancy tank compartments, clearance was secured but in damaged condition. Finally, by augmenting
buoyancy tank volume and changing mudmat timber type, clearance was secured.
