Blast Resistant Consulting and Site Services

Detailed blast resistant analysis and design calculations are providedfor gas metering cabin building for dry gas diverter manifold project to accommodate the specific requirements of MLNG.

The gas metering cabin is designed to satisfy requirements of blast resilient building which can withstand blast overpressure of 15kPa with duration of 110ms. The blast resistant design is based on ASCE guide “Design of Blast Resistant Buildings in Petrochemical Facilities” , PTS 34.28.00.31" Steel Structures", PTS 34.00.01.30 "Minimum Requirements for Structural Design and Engineering', and DEP 34.17.10.33 "Portable Blast Resistant modules".

Detailed blast resistant analysis and design calculations are provided for Field Auxiliary Room (FAR 19) for dry gas diverter manifold project–melor phase II to accommodate the specific requirements of MLNG.

FAR 19 is designed based on requirements of blast resistant building where the blast load is between 45 and 65 kPa with duration between 50 and 150 ms. In current design, the blast load 55 kPa with duration 100 ms is adopted. The blast resistant design for FAR 19 is based on ASCE guide “Design of Blast Resistant Buildings in Petrochemical Facilities”, PTS 34.19.20.31"Reinforced Concrete Foundation and Structures", PTS 34.00.01.30"Minimum Requirements for Structural Design and Engineering", PTS34.17.10.30"Blast Resilient and Blast Resistant Control Buildings/Field Auxiliary Rooms", TM5 1300"Structures to Resist the Effects of Accidental Explosions".

The designed office and workshop building is a 2-storey building housing the office and workshop/warehouse facilities. The designed office and workshop building is located at plant south of the production plant and at about 100 meters from the potential blast source at the north east of the buidling and is a 50 mbar type building. The blast overpressure applied on building is 5kPa.

The blast resistant design is based on ASCE guide “Design of Blast Resistant Buildings in Petrochemical Facilities” and Eurocode "Comite Euro-Internaltial Du Beton: Ceb-Fip Model Code 1990". The strain rates of concrete and steel reinforcements under dynamic load is taken into account in the advanced finite element model.

Detailed blast resistant analysis and design calculations are provided for Substation 59 of dry gas diverter manifold project–melor phase II to accommodate the specific requirements of MLNG. The structure is designed to resist a deflagration blast load of 55 kPa with duration of 110 ms.The blast resistant design is based on ASCE guide “Design of Blast Resistant Buildings in Petrochemical Facilities”, PTS 34.19.20.31"Reinforced Concrete Foundation and Structures", PTS 34.00.01.30"Minimum Requirements for Structural Design and Engineering", PTS34.17.10.30"Blast Resilient and Blast Resistant Control Buildings/Field Auxiliary Rooms", TM5 1300"Structures to Resist the Effects of Accidental Explosions".
