6 The Honorable Minister of Petroleum Resources may approve the revalidation of an expired ATC upon appropriate recommendations from the Department of Petroleum Resources.. The validity of a renewed ATC shall not exceed two (2) years and there shall be no renewals for a re- validated ATC. 3.5 CONDITIONS GOVERNING THE CONSTRUCTION OF A REFINERY, PETROCHEMICAL AND GAS PROCESSING PLANT This comprises of fabrication, installation and erection stages. i) The refiner or plant operator shall provide the Department of Petroleum Resources with the following information for necessary reviews and approval before the commencement of fabrication: a). The name and job references of the company appointed as quality control inspectors and Curriculum Vitae (CV) of its principal technical staff. b). All fabrication and welding procedures. These procedures shall generally follow the relevant specifications in the under-listed documents: 1. American Welding Society – Structural Welding Code A.W.S.D.1.1 88 and the subsequent revisions. 2. API Standards 1104 – 17th and subsequent editions for welding of pipelines and related facilities. ii) At the completion of fabrication, the quality control inspecting company shall compile a report confirming that all materials used were strictly in accordance with approved specifications as verified through steel mill certificates with the approved Standards and Codes of Practice. The quality control inspection shall be by Non-Destructive Examination (NDE). Consequently, inspection and certification of all welded parts of vessels, columns and piping shall be by any of the following techniques as applicable viz.: a). Liquid Penetrant Technique b). Magnetic Particle Technique c). Radiographic Technique d). Ultrasonic Technique A comprehensive report of the inspection so carried out shall be forwarded to the Department through the refiner or plant operator. 3.6 ENVIRONMENTAL AND SAFETY CONSIDERATION IN HYDROCARBON PLANTS DESIGN AND CONSTRUCTION 3.6.1 ENVIRONMENTAL FACTORS These shall include all available meteorological parameters, such as the prevailing wind direction, maximum wind velocity, maximum and minimum atmospheric temperature, relative humidity, rainfall, local flood or tide conditions. a) All environmental parameters shall be obtained from independent site survey with all the data gathered being properly documented. b) Soil test and geo-technical investigations shall be carried out for foundation or load-carrying characteristics of the site. c) Contour maps (site plan), showing ground elevations shall be prepared d) Effect of borehole water withdrawal on ground water table shall be investigated and result submitted.
