Autonomous efficiency The contract, with installation in mid-2025, makes Marflet the first Spanish merchant fleet owner to adopt a WAP system. It marks a further landmark development for bound4blue's fully autonomous 'suction sail' eSAIL® technology, which has recently been selected by other leading industry names including Eastern Pacific Shipping, Louis Dreyfus Company and Odfjell. Working by dragging air across an aerodynamic surface to generate exceptional propulsive efficiency, the unique system is simple, robust, highly efficient and requires zero operational input from crew. Sustainable success "This is a very significant contract for us, not only because Marflet is the first Spanish shipowner to join the wind revolution, but also because with this contract, we consolidate the tanker segment," comments José Miguel Bermúdez, CEO, bound4blue.
