Résumé

Company: Global Offshore Services (GOS) – Leading ROV service provider
Challenge: High connector failure rates causing 40% operational downtime on deepwater projects
Solution: Upgraded from budget connectors to HYSF Subsea titanium wet-mate connectors
Results: 60% reduction in downtime, 75% reduction in connector-related failures, ROI achieved in 8 months

This case study documents how GOS transformed their deepwater ROV operations by addressing the root cause of chronic connector failures. Through systematic evaluation, strategic supplier partnership, and disciplined implementation, they achieved dramatic improvements in reliability and profitability.

Key Metrics:

Chapter 1: Company Background

1.1 Company Profile

Global Offshore Services (GOS)

• Founded: 2008
• Headquarters: Aberdeen, Scotland
• Employees: 450+
• Fleet: 22 work-class ROVs, 15 inspection-class ROVs
• Operations: North Sea, Gulf of Mexico, Brazil, West Africa, Asia-Pacific
• Services: Inspection, maintenance, repair, construction support, decommissioning

Deepwater Operations:

• Depth capability: Up to 3000m
• Primary markets: Oil & gas inspection, subsea construction
• Annual dive hours: 45,000+
• Critical success factor: Equipment reliability

1.2 The Challenge (2023)

Operational Context:

In 2023, GOS was experiencing growing pains. Their deepwater business had grown 40% year-over-year, but profitability was declining. Client complaints about downtime were increasing, and several major contracts were at risk.

The Problem:

“Our ROV pilots were spending more time troubleshooting connectors than actually working,” says James Morrison, GOS Operations Director. “We were losing 2-3 days per month to connector-related issues. On deepwater projects with day rates of $150,000, that’s unacceptable.”

Specific Issues:

1. Frequent Failures:
2. 24 connector failures in 12 months
3. Average 20 hours downtime per failure

4. Some failures resulted in equipment loss

5. Root Causes Identified:

6. Water ingress (60% of failures)
7. Contact corrosion (25%)
8. Mechanical damage (10%)

9. Other (5%)

10. Contributing Factors:

11. Budget connectors from multiple suppliers
12. Inconsistent quality
13. Poor technical support
14. Long lead times for replacements

Financial Impact:

“We were being penny-wise and pound-foolish,” Morrison admits. “We saved $200 per connector but lost $20,000 in downtime every time one failed.”

Chapter 2: Solution Development

2.1 Supplier Evaluation Process

GOS formed a cross-functional team:

• Operations Director (project lead)
• Chief ROV Pilot (end user)
• Maintenance Manager (implementation)
• Procurement Manager (commercial)
• Finance Manager (ROI analysis)

Evaluation Criteria:

Suppliers Evaluated:

2.2 Evaluation Process

Phase 1: Documentation Review (2 weeks)

• Reviewed supplier certifications
• Analyzed test reports
• Compared specifications
• Checked references

Phase 2: Sample Testing (6 weeks)

• Ordered samples from 4 suppliers
• Conducted bench testing
• Performed pressure testing
• Evaluated documentation quality

Phase 3: Field Trial (8 weeks)

• Installed samples on 2 ROVs
• Monitored performance
• Collected pilot feedback
• Tracked any issues

Phase 4: Commercial Evaluation (2 weeks)

• Negotiated pricing
• Reviewed warranty terms
• Assessed support commitments
• Calculated total cost of ownership

2.3 Why HYSF Subsea Was Selected

Key Differentiators:

1. Quality:
2. Type test certificates from independent lab
3. Titanium housing (not stainless steel)
4. Better seal design (multiple barriers)

5. 6000m depth rating (vs. 3000m required)

6. Support:

7. 12-hour response time commitment
8. Direct engineer access (not just sales)
9. On-site training included

10. 2-year warranty (vs. 1 year industry standard)

11. Delivery:

12. 3-week lead time (vs. 8-12 weeks for European)
13. Stock program for common parts

14. Expedited options available

15. Price:

16. 40% lower than European premium brands
17. 20% higher than budget suppliers
18. Volume discounts available
19. Total cost of ownership clearly favorable

“HYSF offered the best balance of quality, support, and price,” says Morrison. “Their titanium connectors were clearly superior to the stainless steel connectors we were using, and their price was still 40% below the European alternatives we considered.”

Chapter 3: Implementation

3.1 Rollout Plan

Phase 1: Critical Applications (Month 1-2)

• Work-class ROVs (highest downtime cost)
• Deepwater projects (>1000m)
• Client-critical operations

Phase 2: Full Fleet (Month 3-4)

• All work-class ROVs
• Inspection-class ROVs
• All depth ranges

Phase 3: Standardization (Month 5-6)

• Phased out all legacy connectors
• Standardized on HYSF part numbers
• Updated maintenance procedures
• Completed training

3.2 Training Program

HYSF Provided:

• 3-day on-site training course
• Hands-on installation practice
• Troubleshooting workshop
• Maintenance procedure review
• Documentation package

Attendees:

• 12 ROV pilots
• 8 maintenance technicians
• 4 operations supervisors
• 2 procurement staff

Training Feedback:

“The training was excellent. Very practical, focused on real-world scenarios. The HYSF engineers clearly understood our operations.”
— Senior ROV Pilot, GOS

3.3 Change Management

Challenges:

1. Pilot Resistance:
2. “If it ain’t broke, don’t fix it” mentality
3. Concern about new supplier reliability

4. Habit with existing connectors

5. Solution:

6. Involved pilots in evaluation process
7. Shared failure data (made problem visible)
8. Quick wins on early installations

9. Recognized early adopters

10. Inventory Management:

11. Had to maintain dual inventory during transition
12. Legacy connector phase-out took 6 months

13. Some obsolete connectors had to be scrapped

14. Solution:

15. Phased approach minimized waste
16. HYSF offered trade-in credit for some legacy parts
17. Used legacy connectors on less critical applications first

Chapter 4: Results

4.1 Reliability Improvement

Connector Failure Rate:

Failure Analysis:

“The water ingress failures basically disappeared,” says Morrison. “The HYSF connectors just don’t leak. That was our biggest problem, and it’s now essentially solved.”

4.2 Downtime Reduction

Downtime Analysis:

*Note: Higher average downtime per failure because remaining failures were more severe (not connector-related)

Operational Impact:

• More available days: 12 additional days per year per ROV
• Higher utilization: ROV fleet utilization increased from 72% to 84%
• Client satisfaction: Client complaints down 90%
• Contract renewals: 3 major contracts renewed (previously at risk)

4.3 Financial Results

Cost Comparison:

ROI Calculation:

“The numbers speak for themselves,” says GOS Finance Director. “We spent an extra $24,000 on connectors and saved over $500,000. That’s the kind of investment decision you make again and again.”

4.4 Qualitative Benefits

Beyond the Numbers:

1. Reputation:
2. Client satisfaction scores improved from 3.2 to 4.7 (out of 5)
3. Won 2 new major contracts based on reliability reputation

4. Invited to bid on projects previously out of reach

5. Employee Morale:

6. ROV pilots more confident in equipment
7. Maintenance team less fire-fighting

8. Operations team less stress on critical projects

9. Strategic:

10. Ability to commit to more aggressive schedules
11. Confidence to bid on deeper, more challenging projects
12. Stronger negotiating position with clients

“Our reputation is worth more than the direct savings,” says Morrison. “We’re now known as the reliable operator. That’s priceless in this business.”
