CHEK

The bulk carrier in the CHEK project uses aerodynamically optimised wing sails to capture the forces of the wind in propelling the ship forward using renewable energy. The resistance of the vessel travelling through the water is reduced by deploying a carpet of microbubbles beneath the hull. This reduces friction, lowering the vessel’s fuel consumption and emissions. The vessels are further optimised using automated vessel routing and weather predictions to minimise energy use and work in synergy with the engine and wind propulsion systems.

Technologies applied on the CHEK’s bulk carrier: solid wing sail, air lubrication system, ultrasound antifouling system, waste heat recovery system, gate rudder, automated route optimization.

Technologies

Air lubrication

Reduces the resistance of the vessels by reducing the frictional resistance on the flat bottom of the hull

Automated route optimization

Route optimisation in use already today leads to significant fuel savings. With the weather-dependent energy saving technologies developed in project CHEK, the importance of automated route optimization is further amplified.

Fuel flexible gas engine

The flexibility of the dual fuel engine will be further enhanced by introducing a control function adapting the combustion control to variations in gas quality.

Gate Rudder

Significantly reduce ship resistance if integrated with an optimised hull shape. Their ability to be integrated with other systems such as wind propulsion systems is essential.

H2 hydrogen

Hydrogen fuel will be used to provide continuous carbon-free power, electricity and heat on demand

Hybrid propulsion

The vessel fuel consumption and emissions will be enhanced by means of batteries and cold ironing orchestrated by a sophisticated energy management system

Scalable power train

With wind assistance increasing the variation in propulsion thrust demand, a more flexible engine power plant is required to avoid compromises

Ultrasound anti-fouling

Keeps the hull clean by preventing the formation of biofilm and thereby minimise drag in the long-term

Waste heat recovery

Maximises the conversion of fuel into useful power by converting waste heat from the engine process, which is low-temperature heat into useful electricity

Waste-to-energy

Feasibility evaluation of different technologies for turning various onboard waste streams into a useful energy source

Wing Sails

Provides a significant reduction in greenhouse gas emissions but requires integration with other technologies for a continuous power
