Participation in the Fleet Solid Support Program for the Royal Navy
Integration of Electric Motorized Valves, Control System and HTS Solutions in an International Naval Program
Within the Fleet Solid Support (FSS) program, developed by Harland & Wolff by Navantia UK for the Royal Navy, FJ participates in the construction of three solid support vessels designed to enhance the operational capability of the British fleet.
This strategic international program involves high technical and integration standards, where system reliability, subsystem coherence and regulatory compliance are essential to ensure operational availability.
FJ’s contribution focuses on supplying electric motorized valves, associated control systems and HTS solutions configured according to the project’s technical architecture.
Technical Scope of Supply
The supply includes electric motorized valves integrated with a control system designed to ensure safe remote operation, continuous status monitoring and effective response under demanding operational conditions.
The solution is complemented by HTS sealing systems for watertight cable transits, ensuring structural integrity of critical compartments and protection against fire or water propagation.
Manufacturing and configuration are carried out in accordance with program technical specifications, ensuring:
- Mechanical and electrical compatibility with the vessel architecture
- Full documentation traceability
- Consistency between valve, actuation and control system
- Functional validation prior to final integration
Delivering the solution under a single technical responsibility reduces critical interfaces and simplifies multidisciplinary coordination.

Engineering and International Integration
The international nature of the FSS program requires technical coordination between UK and Spanish engineering teams to ensure alignment in specifications, quality standards and technical documentation.
System integration includes:
- Functional verification of electric motorized valves
- Control logic validation
- Electrical signal and interface checks
- Coordination with shipyard engineering for platform integration
This approach ensures technical coherence within high-complexity logistical vessels and compliance with the program timeline.
Added Value of the Integrated Approach
The combination of motorized valve, control system and HTS solutions under a unified technical responsibility provides clear advantages in large-scale projects:
- Reduction of risks linked to multiple interfaces
- Greater design coherence
- Simplified future maintenance
- Improved documentation traceability
This model is particularly relevant for logistical platforms that must operate continuously and reliably across different mission profiles.
Participation in the FSS Program strengthens FJ’s international presence in strategic naval programs and demonstrates its capability to deliver integrated solutions in newbuild projects beyond the domestic market.
The project reinforces FJ’s position as a technical supplier capable of operating under demanding international standards and in collaboration with major European shipyards.
