Top 8 Air Lubrication System Providers for Ships

Air Lubrication Systems
Air lubrication systems are becoming a serious efficiency option for owners looking beyond single-point retrofits. By injecting air, creating microbubble layers, or forming controlled air cavities beneath the hull, these systems aim to reduce frictional resistance and lower main-engine load. For owners, the attraction is straightforward: lower fuel burn, lower emissions, stronger CII positioning, and a possible hedge against rising carbon-related costs.
Selection Logic
This list favors providers with meaningful commercial visibility, real vessel activity, shipyard or owner relevance, and technology that appears practical for fleet decision makers. The ALS market is narrower than many other maritime efficiency categories, so the final eight includes a mix of full system suppliers, shipbuilder-led ALS technologies, engineering specialists, and control-system developers that owners may encounter during real projects.
Alfa Laval OceanGlide
Alfa Laval’s OceanGlide gives the air lubrication market a major marine-equipment name with global service reach. The system is built around a controlled air layer beneath the flat bottom of the ship, with a focus on efficiency, integration, and operational practicality. For owners, that matters because air lubrication is not only a hull technology. It also relies on compressors, controls, piping, automation, maintenance access, and confidence that the system will keep delivering savings over time.
Best fit
- Bulk carriers, tankers, and vessels with broad flat-bottom areas
- Owners seeking a supplier with global marine-service depth
- Retrofit and newbuild projects where integration support is a major decision factor
Damen Air Cavity System
Damen’s Air Cavity System takes a different route from traditional microbubble concepts. Instead of simply pushing a bubble layer along the hull, the system is designed around controlled air cavities that reduce wetted surface contact and friction. This makes Damen especially relevant for owners comparing air lubrication formats, because air cavities can be attractive where hull geometry, operating speed, and vessel type make stable air retention possible.
Best fit
- Flat-bottom cargo vessels and short-sea ships
- Owners considering air-cavity design rather than only microbubble systems
- Newbuild or docking projects where hull modifications can be planned cleanly
Foreship Air Lubrication System
Foreship is especially relevant in the passenger-vessel and complex-project side of the ALS market. Its background as a naval architecture and marine engineering firm matters because cruise ships, ferries, and passenger vessels often require more than a standard equipment package. The installation has to work with noise expectations, comfort, hotel load, safety rules, machinery spaces, drydock timing, and highly specific hull geometry.
Best fit
- Cruise ships, ferries, and ro-pax vessels
- Complex conversions and high-spec passenger projects
- Owners needing engineering support rather than only equipment supply
HD Hyundai Marine Solution / HD Hyundai Heavy Industries
HD Hyundai is important because air lubrication adoption often happens through the shipyard channel, especially for LNG carriers and large newbuilds. Hyundai Heavy Industries has been associated with proprietary hull air lubrication technology, while HD Hyundai Marine Solution is relevant for retrofit, lifecycle, and decarbonization upgrades. That combination makes HD Hyundai a serious name for owners already building or upgrading vessels through Korean shipyard programs.
Best fit
- LNG carriers and large newbuilds
- Owners building through Korean shipyards
- Fleet upgrades where ALS is bundled with other decarbonization work
Mitsubishi Heavy Industries MALS
Mitsubishi Heavy Industries is one of the more established names in air lubrication history. Its Mitsubishi Air Lubrication System, commonly known as MALS, has been associated with early commercial deployment and public fuel-saving claims on ferries, passenger vessels, and other ship types. For owners, MALS is significant because it shows that ALS is not only a recent decarbonization concept. It has a longer technical pathway that has been refined through real vessel experience.
Best fit
- Japanese shipbuilding-linked projects
- Ferries, passenger ships, and selected merchant vessels
- Owners comparing newer ALS entrants against long-running technology programs
Pascal Technologies
Pascal Technologies belongs on this list because real-world ALS performance is not just about pumping air under a hull. The control problem is critical. Too little air may limit savings, while too much air can waste compressor energy and reduce the net gain. Pascal’s relevance is in advanced control logic and optimization, especially as owners and yards try to make ALS performance more consistent across speed, draft, weather, and sea-state changes.
Best fit
- Owners evaluating ALS performance optimization
- Yards, designers, and system suppliers needing smarter control layers
- Fleet operators focused on long-term operational tuning after installation
Samsung Heavy Industries SAVER Air
Samsung Heavy Industries’ SAVER Air is another shipbuilder-led ALS pathway that deserves attention. It has been associated with large vessel newbuild programs, including LNG carriers and very large container ships. For owners ordering at Samsung, the key attraction is that the ALS can be treated as part of the vessel design conversation rather than a separate aftermarket retrofit. That can simplify structural planning, layout decisions, and class approval work.
Best fit
- LNG carriers and large containerships
- Newbuild projects at Samsung Heavy Industries
- Owners seeking yard-integrated efficiency technology
Silverstream Technologies
Silverstream Technologies is the most commercially visible standalone air lubrication specialist in the market. Its system releases air through hull-mounted units to create a carpet of microbubbles across the flat bottom of the vessel, reducing friction and lowering propulsion demand. Silverstream has become a benchmark name because it has built a large orderbook, strong shipowner visibility, and relevance across LNG carriers, container ships, ro-ro vessels, cruise ships, and retrofit discussions.
Best fit
- LNG carriers, container ships, ro-ro and ro-pax vessels
- Cruise ships and large commercial vessels with suitable hull geometry
- Owners wanting a specialist supplier with strong commercial visibility
