BlueScope Steel (Port Kembla, New South Wales, Australia)
BlueScope Steel required engineering support for the design of a proposed temporary slip plate for the sinter plant waste gas main. The waste gas main (WGM) slip plate housing required replacement to repair operation related corrosion and erosion issues to extend the operating life of the equipment. BlueScope planned to replace the slip plate housing during the sinter plant single fan operating period and required a temporary slip plate to provide isolation during the repair work.
What we did:
- Performed stress analysis (structural assessment) of the temporary slip plate, supporting angle and adjacent WGM section to determine integrity and compliance with standards AS 4100 for structural components and AS 1210 for welds under pressure loads (at design temperature) considering permanent, imposed, thermal and lifting loads.
- Determined deflection/stresses in critical components, welded joint capacities (considering minimum required weld length), bolted connection capacities and confirmed structural integrity.
- Provided modification of WGM 3D model and developed temporary slip plate 2D GA/detail drawings.
- Provided a safety in design statement in conformance with WHS 2017 regulations.
- Issued certificate of compliance indicating design compliance of the ITT-C container in accordance with Cont-029b and relevant Australian standards for strength and serviceability.
Outcome:
Avesta Consulting successfully confirmed compliance of the proposed temporary slip plate design with the engineering principles and intent of standards AS 4100 and AS 1210 considering operating and lifting loads.
