INTRODUCTION PT Medco E&P Malaka, henceforth referred as Company, intends to develop Block-A gas reserves for sales gas supplying to PT Pertamina. The fields of Alur Siwah, Alur Rambong and Julu Rayeu are to be developed in Block-A. All fields are located in East Aceh Region, Aceh Province, Indonesia. The project plans to build Alur Siwah Central Processing Plant to monetize gases from Alur Siwah and Alur Rambong fields. Julu Rayeu gas will be used for fuel gas supply to Alur Siwah Central Processing Plant and produced water will be injected to produced water injection wells in Julu Rayeu. Alur Siwah Central Processing Station (AS CPP) will be designed with capacity to produce sales gas in the amount of 63.25 BBTUD with associated condensate and produced water. Gas processing at AS CPP will consist of sweetening (removal of CO2 and H2S), dehydration and dew point control with the associated utilities and supporting systems. AS CPP will transport sales gas to PT Pertamina via Pertagas pipeline. The sales gas will be transported using 10 km pipeline to tie-in point near Jambo Balee Metering Station where custody meter is to be located. Tie-in point is provided by Pertagas. Condensate production from AS CPP is to be transported to Point B by trucking.

SCOPE This specification covers the minimum requirements governing the design, materials, fabrication/manufacturing, inspection, testing, certification, identification and painting of Flame Arresters for the Blok-A Gas Development Project. This specification is intended to supplement, not replace, the requirements in ASME, ASTM, MSS or other codes and specifications. In case of conflict among the applicable codes, standards, and specifications; Vendor is responsible to inform Purchaser of the conflict, in writing, for clarification and resolution before proceeding with manufacture or procurement of the affected materials. Vendor is not at liberty to assume which requirements govern. Purchaser’s approvals required in this specification shall be obtained before order placement.

Flame arresters fabricated from welding flanges and reducers is not allowed. The flame arrester shall be designed to allow for ease of inspection and removal of internal elements for replacements, cleaning or repair without removal of the entire device from the system. The element design shall maximize venting flow capacity with minimum pressure drop Vendor shall specify the limitation of dimensions for installation of the Flame Arresters. Flame arresters supplied shall also be UL listed or FM / EN approved or ATEX certified or other equivalents Vendor to confirm the type of Flame Arrester by calculation. Vendor may offer different type of flame arrester with supporting calculation Environmental condition refer to Specification for Site and Utility Design Data, BLA-M-TS-00-020 (Contractor ID, S-000-1222-006)
