Analysis of Offshore Blast Wall

Geethu Francis, Vinay Mathews

Abstract: Stainless steel profiled blast walls have been used increasingly in the oil and gas industry to protect people and personnel against hydrocarbon explosions. Understanding the safety of these blast walls greatly assists in improving safety of offshore plant facilities. However, the presence of various uncertainties combined with a complex loading scenario make the assessment process very challenging. In this study the effect of important variables such as thickness and height to optimize the design of profiled blast walls. Here analysis of blast wall with three different profiles namely S1, S2, S3 were done. Analysis is done by applying pressure load on the structure. Analysis is made to consider the influence of geometric uncertainties on the transient dynamic response of these structures. It is seen that the height is the parameter affecting the variation of deformation in S1 and S2 profile and thickness is the parameter influencing the deformation in S3 profile.
