The research on the failure frequencies double walled LNG storage tanks was performed by AVIV commissioned by RIVM.
There are issues about the failure of double walled LNG storage tanks under significant heat load from external sources, , resulting in relative high failure frequencies for this equipment. During 2015, RIVM has asked consultancy firm AVIV to execute a literature survey to obtain relevant data for answering the questions.
During their survey, AVIV did not find statistically sufficient evidence to deviate from the existing failure frequency numbers that have earlier been issued by RIVM. During 2016, AVIV will extend their earlier survey to a more generic basis, allowing potentially more relevant data to be available for the statistical database.
Parallel to this AVIV survey. TNO has carried out experiments under the main Activity ‘LNG storage tank research’ to resolve most of the questions, allowing RIVM together with the extended work of AVIV to come potentially to a new decision about the failure frequencies of LNG storage tanks in the middle of 2016.
