Everllence ESAL Promises 6% Vessel Efficiency Gain | Mariner News

Everllence has launched Engine Supported Air Lubrication (ESAL), a new technology that integrates hull air lubrication with air drawn from the vessel’s main engine. This development promises net efficiency gains of up to 6%, directly addressing operational cost pressures and environmental targets by significantly reducing fuel consumption and emissions.

The company highlights that ESAL provides value irrespective of future fuel choices or regulatory developments. This positions the technology as a versatile solution for an industry navigating an uncertain decarbonisation pathway, allowing owners to enhance efficiency without committing to specific alternative fuels or facing evolving carbon pricing schemes.

With multiple onboard trials already conducted across several vessels, ESAL’s ability to reduce fuel consumption translates directly into lower absolute emissions and decreased exposure to volatility in both fuel prices and evolving compliance costs. This offers a clear financial advantage for vessel owners and operators, enhancing asset competitiveness in charter markets.

Per Cato, SVP, Head of Engineering Two-Stroke at Everllence, underscored that improving energy efficiency is a fundamental step in shipping’s transition to net-zero operations. The 6% gain represents a significant contribution to immediate emission reductions, providing a tangible pathway to lower a vessel’s carbon footprint without mandating a shift to alternative fuels.

This technology offers a pragmatic approach to enhancing fleet efficiency and managing operational expenditures in the near term, bridging current operational demands with long-term sustainability goals.
