The worlds first compressor-free, passive air lubrication system offering the vessel owner genuine fuel savings

Armada pod and engineering design

The Armada passive air lubrication system (PALS) uses the ship’s forward motion to create a precise air: water mixture for lubrication. Unlike traditional methods that rely on high-energy compressors, PALS consumes significantly less power, utilizing small capacity water pumps only in sub-optimal conditions. With its performance control system and machine learning, PALS ensures good bubble control and delivery.

Optimal Bubble Distribution
With PALS, each bubble counts. Our cleverly engineered venturi system, partnered with the vessel’s forward motion, naturally forms an optimal bubble spread that ensures thorough lubrication of the hull without using compressors! PALS stands out with its innovative passive air injection mechanism, tailored to adapt bubble production precisely to your ship’s type and current conditions—be it speed, depth, or weather—guaranteeing continuous ‘smooth sailing’ unlike traditional air lubrication systems that struggle with deeper drafts and lower speeds.

Unmatched Versatility Under Varied Conditions
Slow steaming and energy regulations are the new industry normals, and PALS is engineered to excel under such conditions. Utilizing minimal energy, our boost pumps step in under less-than-ideal circumstances to maintain peak performance. That translates to consistent efficiency, even with slow speeds or higher sea states.

Superior Sea State Adaptability
Sea conditions can heavily influence performance—but not so with PALS. Regardless of choppy waters or calmer seas, PALS maintains its drag reduction effectiveness.

Ready to revolutionize your ship’s efficiency and operating costs? 

The cost of PALS varies depending on the ship, but it offers low capital investment and operating costs compared to other hull lubrication technologies. By eliminating compressors and using less power, PALS not only reduces drag but also provides economic benefits to shipowners in a short period of time.

For vessels with short-duration, multi-port routes, PALS still delivers significant fuel savings and CO2 reductions. In fact, it not only reduces fuel consumption for achieving ordered speeds but also enables higher speeds with the same power delivery. This speed increase is especially attractive for liner trades with tight schedules, allowing more time in port and increased financial benefits.

RETROFIT55:  “HYKAT” Testing

  • Results demonstrated a significant drag reducing effect of PALS as a result of a stable, well-engaged, high-quality carpet of aerated water in the boundary layer
  • The Armada team documented a drag reduction ‘sweet spot’ that could be targeted where two identified hydrodynamic phenomena were effectively balanced within each and every operating condition
