Case Study #1: Portuguese ROV Manufacturer

Customer Profile

• Industry: ROV Manufacturing
• Location: Portugal
• Annual Production: 15-20 inspection-class ROVs
• Previous Supplier: Subconn (Teledyne)

The Challenge

This Portuguese ROV manufacturer was facing three critical problems:

1. Connector costs eating margins: Connectors represented 22% of total BOM—too high for competitive pricing
2. Long lead times: 10-12 week delivery was delaying ROV deliveries to customers
3. 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

The Evaluation Process

They evaluated 5 suppliers over 3 months:

1. Subconn (incumbent)
2. HYSF Subsea
3. Chinese Supplier A (lowest price)
4. Chinese Supplier B (medium price)
5. European alternative (premium price)

Selection criteria: Price, quality, lead time, MOQ, technical support, warranty.

The Solution

Selected HYSF Subsea for:

• Pin-compatible alternatives to 8 most-used Subconn connectors
• 35% cost reduction vs Subconn pricing
• 3-4 week lead times (vs 10-12 weeks)
• MOQ of 20 units (vs 100+)
• Free samples for evaluation
• 12-hour technical support response
• 316L stainless steel standard (same as Subconn)
• IP68 rated to 50m depth (exceeded requirements)

Implementation

“A single failed net inspection can delay harvest by weeks, costing hundreds of thousands. We couldn’t afford unreliable connectors.”

— Operations Manager, Norwegian Salmon Farm

Root Cause Analysis

After investigation, the issues were traced to:

1. Standard 304 stainless connectors (not suitable for saltwater)
2. No freshwater rinse protocol after deployment
3. Connectors stored wet between uses
4. Biofouling buildup masking early corrosion signs
5. Lack of regular inspection schedule

The Solution

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:

1. Month 1: Replace connectors on 2 ROVs (pilot)
2. Month 2: Train staff, implement maintenance protocol
3. Month 3: Roll out to remaining 6 ROVs

The Results (24 Months Later)

ROI Analysis

Investment: €12,000 (connector upgrade)

Payback period: 3.5 months

5-year savings: €196,000+

“The HYSF connectors paid for themselves in the first year. But the real value is reliability—we can’t afford downtime during net inspections.”
