Project anatomy
Contract scope and delivery roles
- Client / authority
- Bapco Refining
- Delivery parties
- NASS Contracting Co. W.L.L. - confirmed award recipient in Bahrain Tender Board's March 2026 monthly report, Marine, structural, mechanical, piping, loading-system, electrical, instrumentation, diving, survey and supply lower tiers - no organization disclosed
- Contract route
- Bapco Refining used a selected LOCAL GCC request for proposals under tender 26/2025/BTB (T78534). Three accepted bids opened on 17 March 2025: Al Hassanain at BHD 16,283,057, NASS at BHD 12,286,739 and Mohammed Jalal option 2 at BHD 19,869,000; the BHD 0 display for option 1 is not a priced alternative. The later monthly award report names NASS at BHD 10,987,831. Tender Board cautions that opened prices remain subject to evaluation and the lowest bidder is not necessarily awarded.
- Execution window
- The published Tender Board records provide no contract-signing date, notice to proceed, duration, site-possession date, shutdown window, mobilisation, first physical operation, completion target or acceptance date for T78534. The March 2026 report period end is an observation date only, not the award or signing date.
- Works package
- The tender description places construction at New Island Wharf Berths 5 and 6 within Bapco Refining's Sitra Port Terminal and states the objective as increasing liquid-cargo handling capacity for larger hydrocarbon cargoes. It does not publish a bill of quantities, issued design, berth geometry, structural components, loading-arm scope, fender or mooring schedule, pipeline tie-ins, dredging, utilities, control systems or commissioning tests.
- Marine interfaces
- The work sits inside an operating export terminal used by Bapco businesses. Berth availability, vessel and terminal continuity, hazardous-area access, live product systems, marine plant, navigation coordination, structural and mechanical tie-ins, shutdowns, testing and return to service are relevant operating interfaces. No cited record confirms how these responsibilities are packaged or assigned.
- Commercial evidence boundary
- The Tender Board opened-bids page records NASS at BHD 12,286,739. The later award report records BHD 10,987,831, a numerical difference of BHD 1,298,908. Public evidence does not explain whether scope alignment, clarification, arithmetic correction, negotiation, exclusions or another mechanism caused the difference. No source establishes contract amendments, payment, contingency, final value, savings or lower-tier values.
