Wind Assisted Ship Propulsion (WASP) based on eConowind-units and VentiFoils enable fuel & emission-reductions in the coming years. In combination with other techniques like CO2-capturing on board or application of Hydrogen as fuel, this can lead to Zero Emission Ocean going shipping for cargo vessels in the future.
In November 2019 the Maritime Innovation Award was awarded to the eConowind-unit. The development and principle of the eConowind-unit and VentiFoils are introduced, based on the “Turbovoile’-principle as developed by Jacques Cousteau. Retrofitting eConowind-units and stand-alone VentiFoils on existing vessels enable those vessels to reduce fuel consumption and CO2 emissions up to levels of 20 % in favorable Bft 5 wind conditions. Actual developments are presented for new Short Sea Shipping designs by Conoship, that can save more than 50% on fuel and CO2 emissions in favorable 5Bft wind conditions.
A new innovative ‘future concept design’ is presented, combining large scale Wind Assisted Ship Propulsion with batteries, FuelCells and Hydrogen: the CONOSHIP 33000 ZE-concept. This General Cargo vessel of Loa = 220 m and 33.000 DWT features ten 30m VentiFoils XL (scheduled development), that can deliver more thrust than required to sail at 11 kn, at favorable wind conditions of Bft 5 and more. The intended operation is to cross the North Atlantic at a speed of 11 kn in 100% Zero Emission mode, using her ‘Large Diameter Propeller’, wind and hydrogen.
An additional method to reduce emissions is the capturing of CO2 in the exhaust on board of LNG-fueled vessels, store it and delivered it ashore for further usage, for example to produce synthetic fuels based on hydrogen & CO2. Conoship International BV preforms research in this subject together with TNO, FME, Meyer Werft and Heerema Marine Contractors and will present results of the initial feasibility study.
The lecture will be given in English.
A short biography:
Name: Guus van der Bles, Director Development of Conoship International BV, graduated in 1986 as a Master of Science at ‘Delft University of Technology’, as a Naval Architect; I gained more than 30 years of experience in the maritime industry, managing an engineering and maritime consulting office and a steel prefabrication plant in the Netherlands.
In 2005 I joined Conoship International BV, the Innovative Ship Design Office; first as leading Naval Architect and since 2007 as Director. The drive to ‘Improve Ship design by customized innovation’, is reflected in various R&D projects and innovative designs, focussing on fuel- and emission reduction, wind-propulsion and LNG, methanol and hydrogen for propulsion.
I worked as Ass. Professor at Delft University of Technology for 1 day/week from 2003 to 2015, were I investigated several methods of Wind Assisted Ship Propulsion. Based on technology developed by Jacques Cousteau we developed at Conoship the VentiFoil and eConowind-unit that were realized from 2016 on by eConowind BV: a powerful modular unit as ease to fit on a vessel as a 40 feet container, using the wind to reduce fuel and emissions for ships at sea.
