Real-world example: A major Brazilian FPSO project used DNVGL-ST-N001 to design the lifting lugs for 8 topsides modules. By following the PDF’s analysis guidelines, they reduced steel weight by 12% while improving the safety margin against fatigue.
The standard provides the acceptance criteria for transporting a 50,000-ton FPSO hull on a semi-submersible heavy transport vessel (dry tow) or towing it fully floating (wet tow). dnvgl-st-n001 pdf
The standard provides a unified, risk-based methodology for planning and executing marine operations. It covers everything from simple towing operations to the complex installation of subsea templates and heavy lifting of FPSO topsides. Real-world example: A major Brazilian FPSO project used
