The CES team has accumulated significant experience in analyzing the structural failure of systems and constructions thanks to the multidisciplinary skills of its experts.  Among the cases treated: the reservoirs structural collupse caused by the accidental failure of the structure of the geo-membrane and the tearing of the fabric and the rupture of the joints of welds. The failure analysis is generally extended to the outer metal support structure in bolted sheet metal sheets exposed to the bursting pressure of the membrane.
