Tharsis Sea-River Shipping has concluded the installation of two retractable wing sails on its 88m, 2,364 dwt diesel-electric general cargo vessel, M/V Tharsis.
The installation tool place at the Neptune Shipyard in Hardinxveld-Giessendam, near Rotterdam. The work was undertaken at the same time as the vessel was having its air lubrication system upgraded.
The 3m x 9m TwinFoil units are supplied by Netherlands-based eConowind and the units are both integrated in a specially designed aluminium Flatrack from which the folding TwinFoil’s can be deployed. The TwinFoil is a wing with a flap principle similar to those used by aircraft during landing and take-off.
“With this installation operating in both river and North Sea routing with varying winds we are eager to see how the rigs perform, especially with the unique combination of this self-adjusting technology in combination with a modern diesel-electric drive,” said Frank Nieuwenhuis, CEO of eConowind.
“Tharsis Sea-River Shipping was one of the first companies to install a diesel-electric propulsion train on its general cargo vessel with the aim of fuel and emission reduction back in 2012. After installation of a hull air lubrication system in 2020 the installation of the Econowind Twinfoil system is a logical next step towards the companies aim of becoming zero emission,” said Jan Albert Bosma, co-owner of Tharsis Sea-River Shipping
The wind-assist equipment will be carefully monitored and evaluated as part of the WASP (Wind Assisted Ship Propulsion) project, which 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 shipowners to research, trial and validate the operational performance of a selection of wind propulsion solutions.
