Document Responsibility: Environmental Standards Committee Issue Date: 17 May 2011 Next Planned Update: 17 May 2016 SAES-A-112 Meteorological and Seismic Design Data 1 Scope This standard defines the basic meteorological and seismic data to be used in the design of all Saudi Aramco facilities. These data are presented in tabular form in Appendix I. Commentary Note: Saudi Aramco meteorological standards are based on the best available data; some locations have longer term data sets than others. As pertinent reference material becomes available, meteorological data for Saudi Aramco installations will be revised and expanded. This entire standard may be attached to and made a part of purchase orders. 2 Conflicts and Deviations 2.1 Any conflicts between this standard and other applicable Saudi Aramco Engineering Standards (SAESs), Saudi Aramco Materials System Specifications (SAMSSs), Saudi Aramco Standard Drawings (SASDs), or industry standards, codes, and forms shall be resolved in writing by the Company or Authorized Representative through the Manager, Environmental Protection Department of Saudi Aramco. Direct all requests to deviate from this standard in writing to the Company or Authorized Representative, who shall follow internal Company procedure SAEP-302 and forward such requests to the Manager, Environmental Protection Department of Saudi Aramco. 2.2 3 References The selection of material and equipment, and the design, construction, maintenance, and repair of equipment and facilities covered by this standard shall comply with the latest edition of the references listed below, unless otherwise noted. 3.1 Saudi Aramco References Saudi Aramco Engineering Procedure SAEP-302 Instructions for Obtaining a Waiver of a Mandatory Saudi Aramco Engineering Requirement Saudi Aramco Engineering Standards SAES-A-113 SAES-M-005 Geotechnical Engineering Requirements Design and Construction of Fixed Offshore Platforms Page 2 of 27 Tabulated acceleration values in this standard were updated and new stations were added in 2007-2008.
