Majid has a Ph.D. degree in structural engineering with +15 years of experience in design and analysis of structures and equipment in the fields of oil & gas, mining and metal production. Majid has been involved in variety of design and fitness-for-service assessment of structures and foundations subject to both static and dynamic loads, off-shore equipment coming to contact with icebergs (soil-structure interaction), metalogical equipment and refractory lining at elevated temperature (pressure vessel thermo-mechanical analysis), stacks under seismic and wind load (vortex shedding analysis), heat-exchangers (fluid-structure interaction), sea transportation, etc. Majid is proficient in numerical simulation and material modelling using implicit and explicit finite element analysis as the main numerical tool in above fields.

Vibratory equipment supported by steel structures require proper design to avoid resonance. Neglecting resonance can result in excessive vibratory response in a structure causing premature equipment failure, fatigue failure of steel members, and lost time for the client. This presentation focuses on a case study where 12 vibratory screens working within a close frequency range resulted in excessive vibrations in the steel structure of a refinery plant. Upon completing a thorough vibration measurement and structural dynamic assessment, a cost-effective solution was devised to isolate the vibration sources by implementing structural steel framing modifications to reduce the vibration across the plant.
