Job Description:
•SASREF has encountered excessive vibration while throttling the bypass valves of control valves of the system that consists of preheated feed piping from feed heat exchanger to feed heater. There are four 2” control valves and 2” bypass valves for each control valve. Vibration assessment of bypass piping system is performed as per Energy Institute (EI) Guidelines to identify probable cause for vibration and suggest mitigations to dampen the vibration.
•SASREF has encountered vibration in the transfer line carrying intermediate residue from crude splitter furnace to column in crude distillation unit (CDU). Vibration assessment of piping system is performed as per Energy Institute (EI) Guidelines to identify probable cause for vibration and suggest mitigations to dampen the vibration. To reduce piping vibration, it is recommended to increase fundamental natural frequency of the piping system. Natural frequency of the system is increased by implementing support modification.
•SASREF has encountered reliability issue in main fractionator reboiler pump due to casing cover leak in Hydrocracker Unit. Stress study has been performed to reduce higher nozzle loads and maintain flange misalignment within allowable limit. It is recommended to modify the suction and discharge piping system with addition of strut supports and redesigning of spring hanger supports.
•Performing stress analysis to resolve vibration issues in the existing piping system and propose modification of the piping system through Management of Change (MOC).
•Review of IFC piping packages, equipment vendor drawings, MR and TBE for pipe and fittings, valves, special pipe supports (spring supports, struts, snubbers etc.).
•Technical assurance for process piping and utilities system and static equipment including pressure vessels, heat exchangers, tanks, relief devices.
•Dealing with technical queries and provide necessary support to execution team.
•Review of Stress analysis of jacketed lines at Sulphur Recovery Units (SRU).
•Managing the team in terms of Personal and Process Safety, Technical Compliance, Quality and Teamwork.
Responsible for Modeling and Stress analysis of critical piping systems using CAESAR II
•Identifying the Stress critical lines from the P&ID and making line list as per the Stress Design Basis
•Markups and Call-out of supports of isometric drawings, selection of supports type and location for critical and non-critical lines, issuing IFC isometric drawings
•Preparing Stress Analysis Report, Pipe Design Calculation Report for FRP (GRP/GRE/GRV) pipes
Research Projects: worked on Clean Water and Clean Energy (KFUPM, KSA Collaboration with MIT, USA) projects and other academic projects - Performance Analysis of Cooling Towers, A simplified model for air humidification with seawater for HDH desalination process, Flow through Staggered Tube Bundles, Analytical and numerical study of convection heat transfer for spherical water droplets with application to cooling tower.
Chhabra Thermal Power Project, Stage-I, Phase-II, 2X250 MW, (EPC Project).
•Kothagudem Thermal Power Station, Stage-VI - 1X500 MW, (Consultancy Project).
Job Description:
•Equipment & Piping Layout Design and Stress Analysis of critical lines using CAESAR II

•Preparation and checking of MTO, technical bid evaluation
•Carrying out various types of Engineering and Design activities related to piping modifications.
•Preparation / checking of piping engineering drawings (Layout, Isometrics, GAD’s)
•Responsible for carrying out Piping Thickness, Piping Specification, Selection and Checking of Pipe Support Drawings for Various Piping Systems.
area: Thermal & Fluid Sciences Thesis: under the title of thesis "Performance Evaluation of Seawater Counter Flow Cooling Towers" study of counter flow cooling tower for fresh water and seawater is investigated experimentally and is validated by simulating the performance by developing a numerical code. The second law (exergy) analysis is also carried out on both fresh water and seawater cooling towers. Furthermore, the performance characteristics of spray (shower) towers are investigated experimentally and compared with the fill packing tower.
