LETS Global was contracted to extend the service life of structural details on a FPSO located outside Macaé on the coast of Brazil. The FPSO had been on site since December 1999. Due to the already long endured service life, fatigue cracks at numerous pallet stools had already started to appear.

After magnetic particle inspection, the LETS Global Ultrasonic Peening Procedure was used to prolong fatigue life of brackets with no cracks. The procedure was also used to remove existing shallow cracks , while simultaneously prolonging the fatigue life.
