The research on the failure frequencies composite hoses was performed by AVIV commissioned by RIVM
Failure of the hoses during the offloading of an LNG tanker truck to the LNG storage vessel is perceived as one of the main contributors to the risk profile of an LNG refuelling station. In 2015, RIVM has asked consultancy firm AVIV to execute a literature survey to obtain relevant data for a possible decision to lower the failure frequency of typical hoses used for this operation.
During their survey, AVIV did not find statistically sound data to update the existing failure frequencies for LNG delivery hoses.
Starting in 2016, RIVM will research the availability of incident data for all fuel transfer systems, to derive update failure frequencies.
Parallel to this AVIV survey, TNO has carried out experiments under the main Activity ‘LNG transfer systems research’ to determine the failure behaviour of composite hoses. The results of these experiments will also be used as input for the updating of the failure frequencies.
