This paper reflects on Francis L. LaQue 's pioneering approach that allowed testing in real-world marine environments and generation of comprehensive, practical data over nearly seven decades. These data are still widely referenced and used in materials selection for marine environments.
Those presently engaged in marine corrosion as well as other aspects of corrosion rely on their collective experiences and those shared by others in dealing with present day challenges. While certainly not the first to recognize or investigate materials performance in seawater and coastal environs F. L. LaQue is perhaps the most respected for inspiring vast amounts of research and testing in this field and equally as important the sharing results thereof. Commencing in 1935 with the support of the International Nickel Company (INCO) and the Ethly Dow Corporation LaQue drew others into identifying critical areas of concern and establishing test programs to address the causes and prevention of corrosion and other material degradation in marine environments.In the ensuing years expansion of seawater and marine atmospheric test facilities at Kure Beach and Wrightsville Beach NC (USA) greatly enabled the exposure and subsequent assessment of tens of thousands of test specimens. Primarily for the benefit of those newin the field of corrosion this paper reflects on the origins of the LaQue inspired activity and provides examples in several key areas spanning 7 decades.co- authorB.

The Houston Ship Channel is a modern engineering feat. Brackish water. Chloride induced corrosion. Subsidence. Change in water levels and exposure conditions. These issues are explored in this paper reviewing methodologies and results of service life modeling from a recent multi-structure assessment by the authors.

A method to test new surface preparation techniques for preparing existing offshore structures for maintenance painting has been developed. This paper will explain how the tests were conducted, how effective each method was at removing salts, and how the coatings performed in the ISO and NASA tests.
An experimental protocol including in situ potentiostat and quasi-static tensile tests to provide an improved understanding of the corrosion behavior of UNS G10210 steel. A local-global finite element method has been proposed to model a steel plate at a ship compartment scale under uniaxial quasi-static tensile/compressive loading.
