Why OEKS
Experience, structured into
an engineering advantage.
Engineering quality depends on more than automation. OEKS is being developed to connect historical project evidence, engineering calculations, standards, discipline expertise and controlled document workflows into a coherent service model.
02 / ENGINEERING
Calculation-led decisions
Process, hydraulic, equipment and utility engineering supported by traceable assumptions, disciplined checking and revision control.
03 / ACCOUNTABILITY
Expert-led verification
AI can accelerate analysis and document preparation; qualified engineers remain responsible for technical review and applicable approvals.
What we do
Engineering services across
the project lifecycle.
A focused portfolio for owners, developers, EPC contractors, technology partners and industrial operators.
01 / DESIGN
Concept, basic & detailed engineering
Design bases, process selection, PFDs, P&IDs, engineering calculations, equipment specifications, multidisciplinary deliverables and document registers.
02 / EPC SUPPORT
EPC / EPCM & tender support
Feasibility studies, scopes of work, ITB packages, technical proposals, bid evaluations, design coordination and engineering delivery planning.
03 / PROCUREMENT
Vendor search, TBA & TBE
Requirements interpretation, vendor-data matching, technical bid analysis, technical bid evaluation, deviation reviews and recommendation support.
04 / OPTIMISATION
Plant retrofit & efficiency
Water conservation, desalination, pumping and cooling optimisation, energy studies, lifecycle cost analysis and practical revamp roadmaps.
05 / ASSURANCE
Supervision & acceptance support
Planned network-enabled support for construction supervision, FAT/SAT, commissioning, start-up, witnessed tests and performance verification.
06 / DELIVERY
Commercial & investment models
Techno-economic evaluation, EPCF / BOO / BOT feasibility and investor-linked structures, including potential shared-savings arrangements.
01 / Actual engineering deliverables
Engineering competence is visible
in the documents we produce.
These are original design documents from the Birjand water-treatment engineering archive—not illustrative diagrams generated for marketing. The examples demonstrate process definition, instrumentation and equipment arrangement.

02 / Project-led experience
Different projects.
Different disciplines. Real outputs.
The OEKS knowledge foundation draws from a broad portfolio, not a single desalination project. The examples below show actual archived design or analytical evidence.
IRAN · WATER TREATMENT
Birjand Water Treatment Plant
Process-flow documents, instrumentation, design layouts and native 3D model records. A representative reference for multidisciplinary water-treatment design.

3D Plant Modelling, Digital Engineering & Simulation
Engineering-led plant modelling, interdisciplinary coordination and physics-based studies; deliverables are defined according to the client scope, software resources and design-verification requirements.
3D plant & piping design
Equipment layouts, routing, isometrics, interdisciplinary models, access assessment and clash reviews. CADWorx / Plant 3D workflows where suitable licensed resources are available.
Process & hydraulic simulation
Water and salt balances, pumping and hydraulic systems, process performance, design scenarios and off-design sensitivity studies.
Thermal and CFD studies
Cooling and airflow modelling, heat-transfer analysis, operating-case assessment and simulation supported by documented assumptions and technical validation.
The OEKS technology direction
AI-assisted engineering.
Human-governed outputs.
A controlled engineering-production platform is in development. Its aim is to shorten repetitive work while improving traceability, consistency and independent review.

Traceability by design
Connect deliverables with their source data, design assumptions, reference documents and revision history.
Engineering before automation
Use AI to support engineers—not to replace verification, engineering judgment or statutory professional requirements.
Designed to scale responsibly
Start from owner-controlled use and extend toward managed participation by verified discipline experts, clients and suppliers as readiness permits.
Development status: OEKS engineering-platform features are under internal development and validation. Public self-service engineering, client accounts, automated design issuance and specialist marketplace functions are not presented as live services.
Engagement workflow
From project need
to accountable deliverables.
01
Define
Understand process requirements, constraints, scope, available data and acceptance criteria.
02
Benchmark
Identify relevant precedents, technologies, vendor options, standards and design deviations.
03
Engineer & verify
Prepare calculations and documents, then check assumptions, interfaces and technical compliance.
04
Deliver & support
Issue agreed outputs through controlled workflows and support procurement or implementation as contracted.
Partner ecosystem
Experts, suppliers and investors.
OEKS is developing a governed collaboration network for engineering assignments, procurement evaluation and efficiency investments. Public self-registration is not yet available.
Technical specialists
Qualified process, mechanical, electrical, I&C, civil and commissioning experts; credential and project-history verification required.
Technology suppliers
Equipment sourcing, technical information, model selection, vendor evaluation and TBA/TBE workflows.
Investment partners
Review economically justified water- and energy-saving retrofits through EPCF, BOO, BOT or shared-savings concepts, subject to diligence.
Our vision
Make deep engineering knowledge accessible, reusable and accountable.
We envision a globally connected engineering ecosystem in which valuable project experience is preserved, expert competence is verified, and engineering information can be converted into dependable project outcomes.
Our mission
Translate experience into better technical decisions.
Our mission is to develop and deliver evidence-based engineering services supported by structured archives, calculation tools, transparent verification and a qualified specialist network.
Initial priorities are water and wastewater treatment, desalination, cooling, energy-efficient utilities and EPC/EPCM engineering support. Longer-term capabilities include controlled client engagement, expert matching and supplier participation.
