Mechanical Pre-Commissioning & Rotating Equipment Maintenance is an 8-week (360+ hour) industrial engineering attachment conducted with Sinopec International Petroleum Service Corporation Uganda on the Tilenga Development Area Project. Attached to the Mechanical Pre-commissioning Section and Fabrication Workshop, the program focuses on rotating machinery servicing, precision alignment, pressure safety systems, piping spool fabrication, and industrial safety compliance. Topics covered include Annulus Gas Compressor (AGC) lubrication system maintenance and dial-gauge motor shaft alignment; reinstallation and flange torque sequencing of calibrated Pressure Safety Valves (PSVs); piping spool verification, carbon steel vs. stainless steel material identification, and weld joint mapping; electrical grounding verification via earthing resistance testing; and strict execution of Lock Out Tag Out (LOTO), Job Safety Analysis (JSA), and Permit-to-Work (PTW) protocols. Topics covered include on-site interpretation for engineering teams, safety briefings, and toolbox meetings; coordinating expatriate work permit documentation and translating during biometrics capturing at Hoima immigration offices; managing arrival medical checkup logistics and medical translation at City Medical Hospital (Buliisa); passport archive management; and testing/translating workplace HSSE safety gear protocols. Topics covered include Quality Assurance document control and Request for Inspection (RFI) lifecycle management; fresh concrete testing (slump test, temperature check, and compression cube casting); geotechnical earthwork quality control via Sand-Cone Field Density Tests (FDT); pre-pour structural reinforcement and formwork inspections against Bar Bending Schedules (BBS); and compliance auditing under BS EN 1992 (Eurocode 2) and BS EN 1997 (Eurocode 7) standards.
