USS Princeton (CG 59): Microbiologically Influenced Corrosion (MIC) and Macrofouling Status of Seawater Piping Systems.

摘要

Preliminary results and observations on the microbiologically influenced corrosion (MIC) and other failures/corrosion problems associated with macrofouling in seawater piping systems on the USS PRINCETON (CC 59) were reported from a shipboard investigation on 23-26 January 1990 in a Naval Ship Systems Engineering Station (NAVSSES) report entitled 'Investigation of seawater piping system deterioration on USS PRINCETON (CC 59). The NAVSSES report concludes that while there was no single cause for all the reported failures, the majority were due to 'damaging flow conditions such as cavitation, turbulence and impingement'. This report acknowledges a pervasive problem of crevice corrosion under 'soft fouling' and under-deposit corrosion. This technical report will describe the microfouling and macrofouling within the seawater piping system of the USS PRINCETON (CC 59) and assess their contribution to the corrosion problems observed. We will further demonstrate that biocorrosion can contribute to the corrosion mechanisms cited in the NAVSSES report.
