Netherlands-based eConowind, developer of the wind-assist VentiFoil product (see SM, Jan), has been contracted to install two of the devices on a cargo vessel being operated by Holland’s Boomsma Shipping BV.
The twin units have been integrated into a specially designed Flatrack container which can be carried on deck and from which the folding VentiFoils can be deployed.
The wind-assist products are ridged aspirated non-rotating wing profiles that create thrust by means of boundary-layer suction. Because of the additional thrust, the ship’s engine power can be reduced to maintain the same speed, thus providing both fuel savings and emissions reduction.
The wind-assist project is being supported by the Interreg North Sea Europe programme, part of the European Regional Development Fund. JS
