Ras Mohaisen sources give 2028, Q4 2029 and 2030 production milestones
Ras Mohaisen has a dated chain from project-agreement signing through EPC award, financial close and ACWA's under-construction classification, but Sharakat's 2028 partial-production and 2030 full-production sequence, ACWA's Q4 2029 PCOD and Lantania's 2025-2029 execution period are not the same milestone. The 3-kilometre offshore scope still needs evidence from marine design through first water and sustained production.
Financial close and construction status do not date offshore installation
Sharakat's February 2025 release establishes project-agreement signing and its December release establishes financial close, initial production of 100,000 cubic metres per day in 2028 and full 300,000-cubic-metre-per-day production in 2030. L&T establishes the March 2025 EPC award. ACWA's year-end report classifies all 300,000 cubic metres per day as under construction and gives Q4 2029 as expected PCOD. Lantania gives a 2025-2029 execution period and 3 kilometres of offshore work; the ESIA establishes the intake-outfall and seabed-work interfaces. None of those sources publishes accepted marine as-builts, completed hydraulic testing, first-water certification or sustained operating results.
Three kilometres of offshore work include trenching, dredging and pipe laying
L&T's EPC scope includes intake and outfall facilities, and Lantania identifies 3 kilometres of offshore work. The ESIA adds seabed trenching, dredging, pipe laying, turbidity controls, brine modelling and marine monitoring. Financial close, environmental modelling and ACWA's under-construction classification do not establish installed pipelines, accepted intake hydraulics, diffuser performance or water available to the offtaker.
Evidence conclusion
The 2028, Q4 2029 and 2030 milestones describe different delivery states
Sharakat schedules initial production of 100,000 cubic metres per day in 2028 and full 300,000-cubic-metre-per-day production in 2030. ACWA gives Q4 2029 as expected PCOD, while Lantania states a 2025-2029 execution period. Sharakat and ACWA materials also use BOOT and BOO labels respectively, but do not provide a common contractual schedule or reconcile the transfer terminology. Approved alignments, seabed work, intake and outfall testing, brine-plume compliance, first water, partial-capacity certification and sustained full output remain separate records.
Outstanding evidence
- Executed BOO/BOOT language and the 25-year offtake baseline
- Definition and reconciliation of the 2028, Q4 2029 and 2030 milestones
- Marine permits, approved alignments and allocation of the 3-kilometre offshore scope
- Trenching, dredging, pipe laying, joints, backfill and as-built hydrography
- Intake screens, fish protection, pumps, electrical and hydraulic acceptance
- Outfall and diffuser integrity, brine dispersion and marine-water monitoring
- SWRO process guarantees, storage, grid connection, solar PV and controls
- First water, partial-capacity certificate, final PCOD and sustained availability
