Règles de conception et d'application des réservoirs de GLR (gaz liquéfié et refroidi) : inventaire et variantes liées à diverses normes.

RLG (Refrigerated Liquefied Gas) tank design, principles, and application rules: inventory and variations across various standards.

Auteurs : MEULEN P. van der

Résumé

This paper aims, by a side by side comparison, to review the major requirements appearing in the following leading design standards (into force or draft) for refrigerated liquid storage tanks; BS 7777 (1973), EN 1473 (1997), API 620 appendix Q (2002), NFPA 59A (2001) and (2006), Draft prEN 1473 (2005) and Draft prEN 14620 (2003). The requirements are analysed from the following points of view: the standards scope and limits of application, design criteria, materials, specific constitutive parts, etc. This paper, mainly oriented to the outer tank design, inspired by the technical requirements content of several "Invitation to Bid", also aims, through some selected characteristic requirements, to highlight the major differences between the above mentioned standards and to identify some contradictory points. Based on past design experience, the possible lack or incompleteness of the criteria versus the typical Invitation to Bid requirements and versus the usual design practices are also pointed out, with a suggestion for further developments in the future standards.
