Sloshel is a joint industry project, which has been undertaken to study full scale tests of real membrane containment systems subjected to the action of breaking waves which model sloshing impacts in Liquid Natural Gas (LNG) tanks of LNG carriers or Floating LNG terminals. This paper focuses on the modal testing, analysis and the reconciliation of finite element models of the Mk III test panel. The effects of varying key material properties in the finite element models is investigated and satisfactory reconciliations were found between the models and identified modal properties. The validation of the model when mounted in the supporting wall in the flume has provided confidence in using it to investigate the panel's response to full scale wave impacts.
Sloshel is a joint industry project, which has been undertaken to study full scale tests of real membrane containment systems subjected to the action of breaking waves which model sloshing impacts in Liquid Natural Gas (LNG) tanks of LNG carriers or Floating LNG terminals. The waves were generated in a water flume using a wave focusing method. Phase two of the project is overviewed in Brosset, Mravak, Kaminski, Collins, and Finnigan (2009). As part of the third phase of this project, an instrumented panel of the Mk III containment system was subjected to an extensive program of testing and part of this phase of the work is presented in this paper. The reader is referred to Bogaert, Brosset and Kaminski (2010) for a description of the Mk III containment system. This paper focuses on the modal testing, analysis and reconciliation of finite element (FE) models of the Mk III test panel. Tests were first conducted with the panel in a virgin state and suspended on soft springs to simulate free-free support conditions.
