Netherlands-based eConowind and Tharsis Sea-River Shipping have announced a collaboration to install two 3x9m eConowind TwinFoil units on the 2,364 DWT diesel- electric general cargo vessel, MV Tharsis.
The wind-assisted solution from eConowind helps to reduce fuel consumption by using the power of the wind to boost propulsion. The TwinFoil is a wing with a flap principle similar to those used by aircraft during landing and take-off. Setting the wings optimally relative to the wind will be done by a small third steering-wing, which is fast and reliable.
The TwinFoil is a further innovation for eConowind next to its previously designed VentiFoils.
The eConowind units are both integrated in a specially designed aluminum Flatrack from which the folding TwinFoil’s can be deployed.
The Netherlands based NG-shipyard will install the system and bring its experience of fabricating aluminum constructions in order to stay under the 2500 kg total weight as needed for the operations on the vessel.
Albert Keizer, CEO of NG-shipyard, commented: “We are very happy to bring our experience in the specific challenges in this project. We specialide in light-weight but durable constructions at sea and focus on high performance ships with sustainable propulsion. This project combines all of that. We can offer the system at reduced costs with the help of the SDS-program of the Dutch Ministry of Economic Affairs and Climate Policy.
“We are delighted to add Tharsis to our customer base and with both river and North Sea routing with varying winds we expect a lot from the TwinFoil. Of particular interest is the combination of this self-adjusting technology in combination with a modern diesel-electric drive, which in theory should give optimal results,” said Frank Nieuwenhuis, CEO of eConowind.
The installation of the system will be the last of five installations under the Wind Assisted Ship Propulsion (WASP) project and it is scheduled for February 2021.
The WASP project is funded by the Interreg North Sea Europe program, part of the European Regional Development Fund (ERDF) and brings together universities and wind-assist technology providers with ship owners to install, research, trial and validate the operational performance of a selection of wind propulsion solutions.
