BP Zhuhai Rock Cavern Project
EPC for 2 full containment underground LPG storage caverns in BP Phase 2 Expansion
Capacity of each cavern was 200,000 cbm
REL prepared and developed all LPG storage cavern mechanical engineering documentation. Scope included definition of piping, valve, instrument, electrical and control interfaces
All design calculations as required by codes, standards and documents as specified in the ITT and Functional Specification for the LPG Caverns shown in the drawings and specifications
General arrangement drawings, including details of openings, nozzle orientations, cavern sumps etc. Fabrication drawings, fabrication, transport, and installation procedures
REL performed a cavern repair and reinstatement portion in the later part of the project, due to mistakes by client’s underground contractor resulting in incomplete grouting of cavern plug. This involved dismantling casing within Butane shaft / down-hole sump area in preparation for the Cavern’s grouting repair works. This is a dangerous undertaking due to a confined space entry and the only point of entry is top-down
