Hyosung LPG Cavern

Hyosung LPG Cavern

This multi-phase project handled by Hyosung Group will include a propane dehydrogenation (PDH) production plant, a polypropylene (PP) plant, a liquefied petroleum gas (LPG) storage tank, and warehouses for LPG and petrochemical products.

The whole complex will cover 60 hectares of the Cai Mep Industrial Zone in Ba Ria-Vung Tau, located near Ho Chi Minh City.

Dextra is supporting the construction of the 240,000-ton LPG underground storage facility by supplying 30,000 units of glass fiber reinforced polymer (GFRP) rock bolts to consolidate the cavern rock face around the 150m deep excavation area.

Injecting sea water inside the rocks around the cavern will create a water curtain that will effectively prevent any oil leakage: in this high corrosive environment, GFRP is the ideal solution.

Dextra GFRP Rock Bolts are cuttable mining anchors based on fully threaded GFRP tendons. The bolts are available in 7 diameters from 20mm to 40mm, delivered with GFRP plate and nuts. Due to GFRP’s lightweight nature, it is easy to handle, transport and installation inside the tunnel.

The facilities are expected to begin commercial operation in 2020.
