DNV has issued Type Approval Design Certification (TADC) to bound4blue for its Model 3-24 eSAIL, which represents the company's largest and most potent suction sail technology. This Model 3 range is specifically engineered for larger maritime vessels, featuring units that vary in height from 24 to 36 meters. The Model 3-24 is the initial design from this series to be deployed, with two units successfully fitted on the MV Baltazar, a newbuild vessel for Klaveness Combination Carriers, in April.
According to bound4blue, the enhanced surface area of the sail and its optimized aerodynamic profile are designed to maximize lift generation. This configuration is expected to lead to greater fuel savings and reduced operational costs for ships. For freight forwarders and operations managers, the wider adoption of such wind-assisted propulsion systems could contribute to more stable and potentially lower bunker surcharges in the long term, as carriers seek to improve vessel efficiency and meet decarbonization targets. While immediate rate impacts might be minimal, it signals a trend towards more sustainable shipping practices that could influence future routing and capacity decisions.
This development underscores the maritime industry's ongoing efforts to integrate innovative technologies to improve environmental performance and operational efficiency. The Type Approval from DNV, a leading classification society, validates the design and safety of the eSAIL system, paving the way for broader implementation across the global fleet.
