Case Study #1: Portuguese ROV Manufacturer
Customer Profile
- Industry: ROV Manufacturing
- Location: Portugal
- Annual Production: 15-20 inspection-class ROVs
- Previous Supplier: Subconn (Teledyne)
El reto
This Portuguese ROV manufacturer was facing three critical problems:
- Connector costs eating margins: Connectors represented 22% of total BOM—too high for competitive pricing
- Long lead times: 10-12 week delivery was delaying ROV deliveries to customers
- High MOQ: 100+ unit minimums forced excess inventory and tied up capital
“We were losing bids because we couldn’t compete on price. Our connector costs were 35% higher than competitors using Asian alternatives. But we couldn’t risk quality—the ocean doesn’t forgive mistakes.”
— CTO, Portuguese ROV Manufacturer

Case Study #2: Norwegian Salmon Farm
Customer Profile
- Industry: Aquaculture (Salmon Farming)
- Location: Western Norway
- Fleet: 8 inspection ROVs
- Operating Depth: 30-80 meters
- Environment: North Sea exposure, cold water, high salinity
El reto
This major Norwegian salmon farming operation was experiencing frequent connector failures:
- Connector failures every 4-6 months
- Downtime during critical net inspection periods
- High replacement costs (€2,000+ per connector)
- Data loss from failed connections during inspections
- Emergency equipment recovery operations (2 incidents)
“A single failed net inspection can delay harvest by weeks, costing hundreds of thousands. We couldn’t afford unreliable connectors.”
— Gerente de Operaciones, Granja de salmón noruega
Análisis de las causas fundamentales
After investigation, the issues were traced to:
- Standard 304 stainless connectors (not suitable for saltwater)
- No freshwater rinse protocol after deployment
- Connectors stored wet between uses
- Biofouling buildup masking early corrosion signs
- Lack of regular inspection schedule
La solución
HYSF provided a comprehensive solution:
- Upgraded to 316L connectors (marine-grade stainless steel)
- IP68 rating to 50m depth (exceeds operational requirements)
- Enhanced seal design (Viton, reduced crevice corrosion risk)
- Implemented freshwater rinse protocol (2-5 minutes after each deployment)
- Monthly inspection schedule (documented checklist)
- Staff training on connector maintenance
Implementation
Phased rollout over 3 months:
- Month 1: Replace connectors on 2 ROVs (pilot)
- Month 2: Train staff, implement maintenance protocol
- Month 3: Roll out to remaining 6 ROVs
The Results (24 Months Later)
| Sistema métrico | Before | After | Mejora |
|---|---|---|---|
| Fallos en los conectores | 2 per year per ROV | 0 | Reducción 100% |
| Maintenance cost | €16,000/year | €6,400/year | -60% |
| Downtime | 12 days/year | 0 days | Reducción 100% |
| Data loss incidents | 4 per year | 0 | Reducción 100% |
| Connector lifespan | 6 months | 3+ years (ongoing) | 5x improvement |
