Liquid Replenishment at Sea (RAS) – Fuel & Fluids Transfer Systems
Van Halteren supplies Liquid Replenishment at Sea systems engineered for reliable fuel and fluid transfer between dissimilar platforms in challenging sea states. We focus on safety, repeatability and interoperability with Allied practices and platform constraints.
Capabilities for Fuel & Fluids
- Connected replenishment (CONREP) for marine fuels and other liquids
- Flow control, pressure management and venturi-based arrangements where required
- Options for simultaneous transfer (platform-dependent)
- Integration with ship control & monitoring for accurate metering
Equipment & Interfaces
- Replenishment-at-sea probe, nozzles, high-integrity hoses, breakaway couplings
- Hose saddles, fairleads, tensioners and stowage solutions
- Signals & communications package for approach, transfer and breakaway
- Designs optimised for maintainability and lifecycle support
Procedure & Safety
- Aligns with replenishment at sea procedures and approach signals used by the operating navy
- Emergency disconnect, spill mitigation and clear breakaway routines
- SOPs and crew training support on request
Platforms & Compatibility
- Oilers/auxiliaries, DDG/FFG/LHD receivers; compatible with aircraft carrier interfaces as specified
- Engineering for US Navy / Royal Navy / Canadian Navy–style approaches (requirements-based)
Publications & Compliance (on request)
- Alignment to relevant Allied publications (e.g., ATP-16, NTTP 4-01.4, legacy NWP) as specified

FAQ
Learn about Liquid Replenishment at Sea (Liquid RAS).
What is Liquid Replenishment at Sea (Liquid RAS)?
Liquid RAS is the safe and secure transfer of fuel and other fluids between ships while underway at sea. The primary goal is to resupply vessels without them having to return to port.
What types of liquids are transferred during Liquid RAS?
Mainly marine fuels and other essential fluids are transferred during Liquid RAS. Our systems are designed to guarantee a reliable and safe transfer even in challenging sea states.
What equipment is used for Liquid RAS?
Specialized equipment is used, including replenishment probes, high-integrity hoses, and breakaway couplings. This equipment is designed with a focus on safety, efficiency, and interoperability with Allied navies’ equipment.
