Water Technology

An offshore pure water maker skid is a compact, modular system designed to produce high-purity water (e.g., Water for Injection (WFI), demineralized water, or ultra-pure process water) in offshore environments such as oil & gas platforms, FPSOs, or ships. These skids must meet stringent industry standards due to harsh operating conditions, space constraints, and regulatory requirements.

Key Components of an Offshore Pure Water Maker Skid
    ⦁ Pretreatment System
    ⦁ Multimedia filters, activated carbon filters, and ultrafiltration (UF) for removing particulates, organics, and microbes.
    ⦁ Reverse Osmosis (RO) Unit
    ⦁ Primary desalination and purification stage.
    ⦁ Electrodeionization (EDI) or Mixed Bed Polishers
    ⦁ For further purification (if ultra-pure water is needed).
    ⦁ Disinfection System (UV, Ozone, or Chemical Dosing)
    ⦁ Ensures microbial control (critical for WFI).
    ⦁ Storage & Distribution System
    ⦁ Stainless steel (316L or duplex) tanks and pumps with sanitary fittings.
    ⦁ Control & Monitoring System
    ⦁ PLC-based automation with remote monitoring for unmanned operation.

Critical Offshore Standards & Certifications
1. Marine & Offshore Compliance
    ⦁ DNV, ABS, BV, LR, or CCS Class Approval – Ensures structural integrity and safety for marine use.
    ⦁ IMO & SOLAS Compliance – For safety and environmental regulations.
    ⦁ MARPOL Annex IV – If water discharge is involved.
2. Pressure & Mechanical Standards
    ⦁ ASME BPVC Sec VIII – For pressure vessels.
    ⦁ PED 2014/68/EU – Pressure Equipment Directive (if supplying to EU).
    ⦁ API 610 (Pumps) & API 682 (Seals) – For reliability in offshore conditions.
3. Water Quality Standards
    ⦁ USP <1231> / EP / JP – For pharmaceutical-grade water (WFI/PW).
    ⦁ ASTM D1193 – Lab-grade water specifications.
    ⦁ ISO 22519 – Guidelines for purified water systems.
4. Electrical & Hazardous Area Certifications
    ⦁ ATEX / IECEx / NEC 500/505 – For explosion-proof components in Zone 1/2 areas.
    ⦁ IEC 60079 – Electrical equipment in explosive atmospheres.
5. Materials & Corrosion Protection
    ⦁ NACE MR0175/ISO 15156 – For H₂S-resistant materials (sour service).
    ⦁ ASTM A240 (316L SS, Duplex) – Preferred for high corrosion resistance.
6. Environmental & Anti-Pollution
    ⦁ OSPAR & EPA Compliance – For zero-discharge or treated effluent.
    ⦁ ISO 14001 – Environmental management systems.

Design Considerations for Offshore Use
    ✔ Compact & Modular – Space optimization for offshore platforms.
    ✔ Shock & Vibration Resistance – Per ISO 10816 or IEC 60068.
    ✔ Redundancy & Reliability – Backup pumps, dual RO trains, and fail-safe controls.
    ✔ Corrosion-Resistant Materials – 316L stainless steel, FRP, or super duplex.
    ✔ Remote Monitoring & Automation – For unmanned operation.
