On Ship Structure Risk and Total Ownership Cost Management Assisted by Prognostic Hull Structure Monitoring

Ships must perform their missions with a high degree of reliability to maximize availability through their service life. The ultimate safety of the hull structure is time-dependent with degradation caused by the operational environment. Achieving the fore mentioned reliability and mission availability requirements are complicated because ships...

The use of odd random phase electrochemical impedance spectroscopy to study lithium-based corrosion inhibition by active protective coatings

In this work, the study of the time-dependent behaviour of lithium carbonate based inhibitor technology for the active corrosion protection of aluminium alloy 2024-T3 is presented. Odd random phase electrochemical impedance spectroscopy (ORP-EIS) is selected as the electrochemical tool to study the corrosion protective properties of a model...

Reliability assessment for corroded pipelines in series considering length-scale effects

This paper presents a method for assessing the reliability of a corroded pipeline placed in series, with special consideration given to the effect of the length scale imposed by each segment of the pipe. The features of corrosion in different pipe segments are statistically correlated; thus, a failure in one section may impact the adjacent...
