ITCO Publishes First Sloshing Report for Tank Containers
London, UK, 14 July 2014: ITCO, the International Tank Container Organisation, has today published a newly commissioned Report focusing on the anti-slosh performance of baffles in tank containers. The Report quantifies the liquid surge forces for a range of liquid and baffle parameters to allow for a comparative analysis against a tank without baffles. The Report shows that baffles with between 50 and 70% cross sectional surface area of the tank provide a similar reduced sloshing performance. The report was commissioned from Concave Research Center, Concordia University, Montreal, Québec, Canada.
(firmenpresse) - The movement of liquid cargo within a tank when being transported is referred to as “sloshing”. Severe effects of sloshing are caused by sudden changes - such as braking and cornering. The effects of sloshing can be reduced by the fitting of transverse baffles, also known as surge plates. The surface area of the baffles is studied by the Report, in order to determine the optimum dimension to be effective against sloshing whilst also ensuring maximum aperture for safe entry into the tank for inspection and tests.
Key findings of the report are:
•Baffles provide a reduction in the transient slosh nature of the forces when compared to tanks with no baffles.
•Baffles with between 50-70% cross sectional surface areas of the tank provide similar performance.
•The effect is complex and is dependent on many factors, such as acceleration, product densities, fill levels, baffle area, etcetera.
•The effect of longitudinal sloshing during sea and rail transport is substantially lower than might potentially occur by road transport.
Commenting on report, Heike Clausen, ITCO President, notes: “By commissioning this Report from Concordia University, Montreal, a leading university in this field of study, ITCO opens the discussion to engineers to provide the way forward to challenging norms and developing further optimum designs that ensure the tank container remains the safest mode of transport”.
The Report - full title “Anti-slosh performance assessments of partial horizontal baffles with different cross-sectional surface areas“ - was commissioned from Concave Research Center, Concordia University, Montreal, Québec, Canada, respected international experts in this field of study and benefits from the use of the latest computerized fluid dynamics techniques. The study was carried out by Professors S Rakheja and A. Kolaei, who have published a number of studies on the subject although this is the first that specifically addresses tank containers.
ITCO considers that the report is a valuable source of time variable data on longitudinal force and pitch moment which will enable the industry to further work to improve safety. As part of ITCO objectives to promote safety of tank container transport, the Report was commissioned to bring a point of reference to the understanding to the subject of stability of the tank in the different transport conditions and to aid engineers in the further development of baffles in tank containers. It is proposed to develop the finding in a Work Group to be arranged at the ITCO General Meeting in October.
The complete report, giving details objectives, model development, method of analysis, results and discussion, can be downloaded by ITCO members from the ITCO website.
ITCO welcomes companies to contribute to the on-going discussion of the report by contacting ITCO Technical Secretary. The first possibility to discuss the report face to face is the upcoming ITCO Meeting in Frankfurt 21st October.
