On the one hand, ZEL will contain the physical hardware of the future engine room. Typical power components are fuels cells, batteries, super capacitors, electric machines, advanced internal combustion engines and a gearbox for hybrid solutions. Supporting components are storage for energy carriers, electrical infrastructure in DC and AC, advanced automation and control systems and integrated cooling and HVAC systems.

Connected to hydrodynamics

On the other hand, the engine room hardware connects to the hydrodynamics through a real propeller in the cavitation tunnel and an additional electric machine which is controlled by sophisticated hydrodynamic algorithms. These simulate the dynamical behaviour including acceleration and deceleration, cavitation and ventilation, behaviour in waves and manoeuvring, etc.

Digital twin

With simulation, monitoring and big data technology, a so-called digital twin of the ZEL has been developed as well. The digital building blocks enables us to build and operate ships in virtual reality. The digital twin accounts for scaling ( effects) and effective system integration.

This concept fits perfectly with our focus on the complete lifecycle of ships and the ambition to make them smarter and cleaner. With the help of these facilities, risk and costs will be substantially reduced.
