Tender Details
Description / Scope of Work
Pakistan State Oil Company Limited (PSO), headquartered in Karachi, Sindh, invites quotations for an annual contract covering monthly inspection and condition assessment services for product pumps and electric motors at PSO Keamari Terminal A. The scope encompasses comprehensive on-site physical inspection, functional checks, and vibration and thermal measurement of eighteen centrifugal pump-motor sets: ten units in the Gasoline Section and eight units in the Kerosene Section. Inspections are to be conducted on a monthly basis (seventy-two jobs annually) with equipment running under operationally feasible conditions to capture real-time performance data including vibration velocity per ISO 20816-3, bearing and casing temperatures, discharge pressure, power draw, noise levels, mechanical seal integrity, coupling alignment, and overall visual condition assessment. All work must be executed under valid PSO Work Permits (Hot or Cold Work) with coordination of HSE and Operations personnel.
The contractor shall inspect pump-motor sets as single units, recording findings against standardized PSO checklist headers including client name, location tags, pump and motor identification. Inspection parameters for pumps include discharge verification against pump curves, developed head confirmation, power consumption analysis, mechanical seal and bearing seal assessment, coupling condition, foundation integrity, and noise characterization. Motor and control unit inspections cover cooling fan integrity, end shield condition, bearing greasing schedules, connection box moisture protection, cable and conduit insulation, starting circuit operation (soft starters, VFDs, or star-delta), voltage relays, overload relay settings, ampere and voltage meter readings, indication lights functionality, internal panel wiring condition, and motor frame and bearing temperature monitoring against NEMA/IEC insulation class limits.
Quotations must be submitted by 29 October 2026. Bidders should provide unit prices for the monthly inspection job code in Pakistani Rupees. PSO requires earnest money and purchase order or demand draft details to be specified. Detailed equipment schedules and standard inspection checklists will be issued upon contract award. The contract location is PSO Keamari Terminal, Karachi, with all coordination through PSO's Operations and HSE departments. Interested vendors should contact PSO House, Khayaban-e-Iqbal, Clifton, Karachi-75600, Pakistan, by telephone (021) 9203866-85 or facsimile (021) 9203796 for queries or access to complete bid documents and annexures.

PSO seeks monthly inspection and condition assessment of 18 centrifugal pump-motor sets (10 gasoline, 8 kerosene) at Keamari Terminal—72 jobs annually.
Scope is technically demanding: vibration/thermal trending per ISO 20816-3, mechanical seal integrity, motor insulation class compliance, coupling alignment, and real-time performance capture under operating conditions. Contractor must hold valid PSO Work Permits and coordinate with HSE/Operations. This is a recurring annual contract with standardized checklists but requires specialized instrumentation and expertise in pump hydraulics and motor electrical diagnostics. Scale suggests medium-sized SME with calibrated equipment.
Who can bid: Typically, vendors require NTN/FBR registration, valid PSO vendor registration, and demonstrated capacity to obtain Hot/Cold Work Permits. No PEC category stated as this is maintenance/inspection rather than construction. Must evidence ISO 20816-3 vibration measurement capability and motor thermal testing competency. PSO Work Permit eligibility (HSE coordination) appears mandatory.
