Vindskip® a carbon-robust ship concept running on the wind, biogas & LNG

The shipping industry is under increasing pressure to act upon the Paris agreement and reduce greenhouse gas (GHG) emissions.

For many decades, international shipping has been running on heavy fuel oil. This is causing ocean acidification, acid rain and other negative environmental impacts. Exhaust gases from ships are also causing premature death in humans worldwide. Consequently, the use of heavy fuel oil must be reduced.

The UN Maritime Organization (IMO) has therefore implemented a strategy to cut greenhouse gas emissions by at least 50 per cent by 2050. It has also introduced the Sulphur 2020 cap to cut emissions of sulphur oxides (SOx) and nitrogen oxides (NOx).

Vindskip® reduces emission with its award winning design Developed by Lade AS, Vindskip® is the winner of the world-renowned German Design Award 2020 in the category Excellent Product Design – Conceptual Transport.

A perfect match

Car manufacturer offers Sustainable Mobility while Vindskip AS offers Sustainable Ocean Transport

The main KPI to be measured for our customers, is the value of emissions per transported car per 1000 km. Through the novel ship concept Vindskip®, we will achieve this goal and offer the market’s lowest emission for sea transport available in the Deep Sea Car Carrier segment.

Low-emission pure car and truck carrier

The Vindskip® design features a dynamic fuel-saving system using wind, cruise control and weather routing. Together, these can yield an estimated reduction in fuel consumption of up to 60 per cent.

The hull itself acts as a giant sail, harnessing wind energy to create propulsion and reducing drag by up to 75 per cent. The cruise control keeps the vessel cruising at a constant speed, regardless of wind availability. Finally, the highly accurate weather routing module calculates the optimal route for the ship to travel, in terms of fuel economy or ETA.

Vindskip® features a lightweight construction, which further reduces fuel consumption, while a highly stable underwater hull design virtually eliminates the need for ballast water.

Vindskip® is powered by a dual liquefied natural gas (LNG) and liquefied biogas (LBG) propulsion system. The two fuels can be mixed, enabling bunkering of whichever one is available.

The concept has been tested in a wind tunnel and a towing tank under extreme conditions. The complete hull above the waterline has been optimised using computational fluid dynamics. Fuel consumption and route regularity have been well documented by repeated simulations using the weather routing module and historical weather data.

Concrete benefits

Vindskip® is a carbon-robust ship design that will remain competitive in the face of more stringent CO2 regulations in the future. It exceeds current emission requirements and will meet all new regulatory aims through 2050.

Zero emission

To be able to decarbonize the international maritime industry entirely, fuel other than low carbon LNG, will be needed.

Decarbonisation of the maritime shipping sector requires the use of zero/ low carbon fuels and the use of liquified biogases. LNG- fuelled ships can use liquified biogases without major modifications, and a technically mature LNG infrastructure would only need to be scaled up.

The Vindskip®-concept has already taken this into account, with a technology solution that allows the mixing of LNG with liquified biogases, LBM or LSM. This gives freedom also in terms of bunkering where these fuels are commercially available and a pathway to reduce the emission close to zero.

When running on the wind and LNG, estimated total reduction in emission compared to a reference ship running on heavy fuel oil:

WRM-calculated reduction in emission compared to reference ship running on HFO
Emission Reduction in emissions compared to reference ships running on HFO Estimated total reduction compared with reference vessels per year (ton)
CO2 63 % 19 476
NOx 96 % 898
