OEM Customized Solutions – Designed for Your Platform, Not a Catalog

Marine supporting facilities are never one‑size‑fits‑all. Your platform may have space constraints, crane limitations, power availability differences, or specific environmental compliance targets. We treat every project as a custom engineering engagement.

What we customize:

Your Constraint	Our Customization
Limited deck space	Vertical stacking of modules (e.g., water treatment under workshop) or compact footprint designs
Low crane capacity	Split single skids into multiple 5‑8t modules for easy lifting
No dedicated power supply	Diesel generator skid with day tank – self‑contained
Harsh environment (H₂S, high humidity)	TSA coating, 316L stainless steel wetted parts, explosion‑proof everything
Cold climate operation	Arctic‑grade insulation, heated enclosures, low‑temperature hydraulics
Remote monitoring requirement	4G/5G telemetry system – we’ve done up to 50km from shore
Specific discharge limits	Customized treatment trains (ultrafiltration, reverse osmosis, evaporation)
Multi‑platform deployment	Interchangeable module designs with standardized quick‑connect interfaces

Our engineering process for marine supporting facilities:

1. Discovery: You send platform layout, weight budgets, power availability, environmental targets, and headcount.

2. Engineering study: Within 3 weeks, our multi‑disciplinary team (mechanical, electrical, civil, process) produces a facility layout, weight report, and single‑line diagrams.

3. 3D model review: Shared online for your platform integration team.

4. Fabrication in ISO‑9001 facility: All skids pressure‑tested and function‑tested.

5. Pre‑commissioning: Full system test at our yard – you witness.

6. Shipping & offshore installation: Our field engineers supervise placement, hook‑up, and commissioning.

Frequently Asked Questions (FAQ)

Q1: What exactly is included in "marine supporting facilities”?

A: These are all the auxiliary systems on an offshore platform that are not directly part of drilling or production equipment. Typical inclusions: power generation, water treatment (freshwater, produced water, slop water), sewage treatment, fire fighting systems, gas detection, deck machinery (cranes, winches, BOP handling), accommodation modules, HVAC, workshops, compressed air, and chemical injection skids.

Q2: Can SJ supply a complete support facilities package for a new platform?

A: Yes – this is one of our core strengths. We supply integrated facilities packages for entire offshore platforms. You provide the platform layout and operational requirements; we provide the detailed engineering, fabrication, and on‑site installation support.

Q3: What certifications do your marine supporting facilities carry?

A: All pressure‑containing components are API or ASME certified. For classification society requirements (DNV, ABS, BV, CCS), we can provide certification per your project spec – additional lead time applies.

Q4: How do you handle corrosive marine environments?

A: Standard: C5‑M marine coating (tested to 3,000+ hours salt spray), stainless steel fasteners, IP56 electrical enclosures. Upgrade options: thermal spray aluminum (TSA) coating, 316L stainless steel wetted parts, and full marine grade aluminum for helidecks and living modules.

Q5: What is the typical lead time for a supporting facilities package?

A: Depends on package size and complexity. Small packages (e.g., chemical injection + water treatment + sewage): 4‑6 months. Medium packages (add power generation + deck crane): 6‑8 months. Full platform support facilities (all systems): 8‑12 months. Rush options available.

Q6: Do you provide offshore installation and commissioning?

A: Yes – every major facilities order includes on‑site supervision of placement, hook‑up, and system commissioning. Typical on‑site duration: 2‑6 weeks depending on package size. We also provide remote commissioning via video link for simpler systems.

Q7: What training do you provide for platform crews?

A: Standard: 1‑2 weeks on‑site training covering operation, daily checks, and troubleshooting of each system – power, water treatment, crane, fire system, HVAC, etc. We supply laminated quick reference cards and full PDF manuals.

Q8: What warranty applies to marine supporting facilities?

A: 18 months from shipment or 12 months from commissioning. Major mechanical components have 24‑month warranty. Extended warranty options available.

Q9: Can existing platforms add these facilities (retrofits)?

A: Yes – we specialize in retrofits. Because our systems are modular and skid‑mounted, they can be lifted onto existing decks with platform cranes. We conduct a detailed deck load study and integration engineering before fabrication.
