<p>Safety on for example an offshore gas or oil platform is enhanced by constructing it with walls (138) formed from fireproof sheets having predetermined resistance to plastic deformation caused by shock waves generated by blasts due to explosive ignition of for example escapes of gas. This resistance to plastic deformation will exceed a predetermined value for the fireblast wall (138) concerned which will itself be determined by inputting into a database of elastic behaviour data for structural beams (A, B, C, D) which are to extend lengthwise and transversely in a supporting framework of the fireblast walls. A computer program is then run to yield instructions for provision of an array of structural beams for providing generally at minimum cost, a minimal deflection of a shock wave incident normally on the wall sufficient to achieve the predetermined resistance to plastic deformation.</p> |
