The David Taylor Model Basin, Carderock Division, Naval Surface Warfare Center, Bethesda/US, has over the past few years initiated a number of research efforts which have and are continuing to address various aspects of the behaviour of double hulls and their components to primary compressive loadings. These studies have as their ultimate goal the development of practical, user oriented design methods for double hull structure and as suchcurrently focus on more approximate, rather than mathematically rigorous,approaches to the various structural phenomena being considered. This paper is in essence a progress report on a selected number of these efforts and describes the results achieved to date as well as the ongoing efforts and those planned for the future. This report focuses primarily on three recent studies: (1) a preliminary look at the relative significance of localversus general instability failure of double hull structure; (2) small scale experimental analysis of double hull sections using rigid vinyl modelling; and (3) the application of beam-on-elastic-foundation analysis methods for high aspect stiffened plates as it relates to double hull structure.In addition to these major topics, the report also includes a brief discussion of other ongoing and planned efforts relevant to the advanced doublehull.
