Classification society ABS has completed a review of bound4blue's proprietary force matrix methodology, which is used to calculate Pwind values for wind-assisted propulsion systems (WAPS). Pwind represents the propulsive power generated by such systems, like bound4blue's eSAIL suction sails.
The company's methodology integrates computational fluid dynamics (CFD) modeling with wind tunnel-validated tools to create vessel-specific aerodynamic force matrices. This approach allows for accurate assessment of sail-to-sail and ship-to-sail aerodynamic interactions without requiring full-scale physical testing.
For freight forwarders and shippers, this development is significant as it provides a more robust and validated framework for quantifying the environmental and economic benefits of wind propulsion technologies. Increased confidence in these calculations could accelerate the adoption of WAPS, potentially leading to more fuel-efficient vessels in the global fleet. This could, in turn, contribute to lower bunker surcharges and more stable transit times as carriers seek to optimize operational costs and meet decarbonization targets. While direct rate impacts are not immediate, the long-term trend points towards a more sustainable and potentially cost-effective shipping environment.
