Critical level survey of product storage tanks at multiple PSO operations locations

Pakistan State Oil Company Limited (PSO) invites quotations for a comprehensive survey of critical high levels (HHLA) of product storage tanks across five operational locations in Sindh province. The scope encompasses detailed surveys at Buffer Oil Terminal (BOT) with 2 tanks, Daulatpur Depot with 1 tank, Faqirabad Depot with 2 tanks, New Faisalabad Depot with 10 tanks, and Juglot Depot, totalling approximately 16 tanks of varying sizes and capacities storing HSFO, HSD, PMG, SKO and R95 products. Surveys must be conducted in accordance with API MPMS Chapter 2.2 standards using Electro-Optical Distance Ranging (EODR) technology to establish critical high-level reference points required for tank level alarm installation. The vendor is required to provide detailed general arrangement drawings of tank shells, roofs and foundations with all nozzles, equipment, platforms, ladders and appurtenances marked with dimensions and elevations from reference points, along with comprehensive survey reports including measurements, calculations, methodology and conclusions.

The quotation must cover survey work (measured in each tank as a separate unit) and mobilization, demobilization, boarding and lodging charges for deployed personnel for the full project duration. Bidders must be capable of executing precision surveying work on storage tank infrastructure using advanced optical ranging technology and producing detailed technical documentation compliant with international petroleum measurement standards. Submissions must include unit prices for each survey location and transportation costs, with all deliverables including completed datasheets as specified by PSO.

Quotations must be submitted by 06 August 2026. This is a price enquiry and not a binding order. Interested vendors should review the complete scope of work, tank specifications and technical requirements detailed in the RFQ document before preparing and submitting their quotations to Pakistan State Oil Company Limited, PSO House, Khayaban-e-Iqbal, Clifton, Karachi-75600.

PSO seeks specialized tank surveying services across five depots and a terminal, covering 16 tanks ranging from 5m to 43.49m diameter. The work demands API MPMS Chapter 2.2 compliance and EODR technology capability — not typical construction or mechanical services. This is a technical specialist procurement; surveyors without petroleum infrastructure expertise and optical distance ranging equipment should not bid. Single quotation deadline with no visible pre-bid meeting suggests PSO may have pre-identified capable vendors. Scope spans multiple locations and product types (HSFO, HSD, PMG, SKO, R95), implying multi-week deployment and logistical planning. Scale appears medium to large given site count and documentation intensity.

Who can bid: The notice does not explicitly state registration or licensing requirements. Typically, surveying services in Pakistan require the bidder to be registered with the Engineering Council of Pakistan (PEC) under appropriate category, hold a valid NTN from the Federal Board of Revenue, and possess relevant ISO certifications for quality assurance. For petroleum-related work, previous experience on PSO or major oil company projects is often required. Vendor must demonstrate equipment capability and technical competence in EODR surveying.
