Wind-Assisted Propulsion Systems (WAPS) offer significant potential for reducing fuel consumption and emissions in the maritime industry. But how can you accurately measure the true benefit? VAF provides the answer with Vento – our advanced system for monitoring wind propulsion effectiveness onboard.

Introducing VAF Vento

VAF has developed the new Vento system to tackle the challenges of measuring wind-assisted propulsion. Vento directly measures the real-time reduction in propeller thrust caused by wind propulsion, delivering clear, verifiable insights into fuel savings and emission reductions.

Vento sets a new standard for transparency in wind propulsion. By continuously tracking propeller performance, it supports:

• Optimization of sail technology and vessel operations

• Accurate attribution of fuel savings to wind propulsion

• Fair cost-benefit sharing between shipowners and charterers

With rising regulatory demands, Vento provides the data-driven confidence needed to comply with key maritime regulations, including:

• IMO Carbon Intensity Indicator (CII)

• FuelEU Maritime

• Global Fuel Standard (GFS)

Why choose VAF Vento?

Vento empowers ship operators and charterers with:

• Accurate, real-time measurement of propeller thrust, torque, and power

• Instant insights into when wind propulsion takes over

• Quantifiable data on fuel savings and emission reduction

• Smart engine load optimization for improved efficiency

• Seamless integration with dashboards and control systems

By delivering high-resolution performance data, Vento builds trust in wind propulsion technologies and drives the maritime sector toward cleaner, more efficient operations.
