LETS Global main field of business is the fatigue life extension of areas of structural integrity concern in offshore structures by ultrasonic peening. The Life Extension in offshore installations is achieved by applying a wide structural integrity concept which embraces FEA (Finite Element Analysis) modeling, localization and assessment of hot-spot stresses as well as the treatment in-situ by ultrasonic peening of high stressed areas. We have extensive experience on ultrasonic peening treatment offshore in the North Sea, Gulf of Mexico and Brazil. The ultrasonic peening treatment is normally carried out while the installation is in full operation which brings considerable economical advantages. The economical benefits due to reduced maintenance of offshore structures by ultrasonic peening treatment include: - Avoidance of long term plan for extensive repair work - Avoidance of long and unscheduled operational disruptions - Increased structural safety for the structure during remaining service life
