DNV releases new methodology for offshore fatigue design/operation
Offshore staff
HOUSTON -- A new update of DNV's "Recommended Practice Fatigue Design of Offshore Structures" is now available, the company announced at the 2008 Offshore Technology Conference today in Houston.
The new version has been updated in order to meet increased industry focus on the design of cost-optimal structures and the reliable operation of existing structures during their service life.
"The fatigue design of steel offshore structures has become a key issue as these are becoming more optimized with respect to weight, fabrication and cost. So in order to obtain structural designs which function properly during in-service life there has been a demand for more user-friendly, efficient, accurate, and reliable standards," says Inge Lotsberg, chief specialist at DNV.
DNV's "Recommended Practice Fatigue Design of Offshore Structures" has been issued to meet this demand. It has been improved with respect to the reliability of fatigue design based on new research and experience related to welded plated structures.
New types of dynamic loaded structures used to generate wind and wave energy are also covered in the new update. "The enhanced methodology is based on new research and experience and is utilized to ensure the safe operation of offshore structures and transportation of compressed natural gas," says Lotsberg.
