A for fitness-for-service evaluation was conducted in simulated seawater injection conditions for three levels of dissolved oxygen (30, 50, and 100 ppb) to assess the effect of upsets in control of the deaeration. Four materials were studied: austenitic UNS S31603, duplex UNS S39274, and two nickel base alloys
Two successive leakages were reported in the heat exchanger composed of 8 rows of finned tubes of the convection section of the condensate stripper re-boiler. A comprehensive study (Failure Analysis) has been conducted to reveal the form of failure. The failure was recognized as erosion and cavitation damage.
