Seyffert, Harleigh C. (author), Kana, A.A. (author), Troesch, Armin W. (author)This paper examines the performance of 6 stiffened ship panel designs in different operational profiles. The main question of interest is: which sea states will lead to the worst panel performances in terms of reliability? As stiffened panel collapse is governed by combined lateral and in-plane loading effects (non-linear functions of the...conference paper 2021

Seyffert, Harleigh C. (author), Kana, A.A. (author)Evaluating marine system reliability requires considering the interaction of a limit state with the stochastic ocean excitation. Given a range of operational profiles, a relevant question is which sea states lead to the worst-case system responses, considering the effects of short and long-term variability. If the identified subset of...journal article 2020

Seyffert, Harleigh C. (author), Kana, A.A. (author), Troesch, A. W. (author)Response-conditioning wave techniques are a rational way to link wave excitation environments with return-period extreme loading responses. By retaining the wave excitation which leads to a design response, these techniques can also define extreme combined loading scenarios. For complex or novel hull forms, combined loading may be relevant...journal article 2020

Kana, A.A. (author), Brefort, D.C. (author), Seyffert, H.C. (author), Singer, D.J. (author)This paper introduces a novel decision-making framework for planning lifecycle compliance of ballast water treatment by applying eigenvalue spectral analysis<br/>to the ship-centric Markov decision process (SC-MDP) framework. This method focuses on identifying the relationships of various decision making scenarios, and how those relationships...conference paper 2016
