EU-PROJECT KITVES
●
Airfoil-based solution for Vessel on-board energy production
destined to traction and auxiliary services
●
Working height: 200m – 1000m
●
Kite is equipped with sensors and independent power supply
●
Actuators and steering in the unit on deck (Kite Steering Unit)
●
Autonomously performed cyclic two-phase manoeuvre:
traction and recovery phase
●
Surface of the Kite: 25 m²
●
Rotation angle around Z-axis: 480°
●
Nominal power: 100 kW
Financed within the 7th Framework of the EU

HARVESTING CYCLES: TRACTION PHASE
Wind
Kite is lifted by the wind

Kite
Elliptic ascent of the kite maximizes the amount of
generated energy
●
Lines unroll
●
Drums are put in rotation
●
Generators produce energy.

HARVESTING CYCLES: RECOVERY PHASE
●
Started by the control when the maximal length of the
lines is reached
●
Lines are pulled in by the motors with a short delay
between the first and the second line
Wing area exposed to the wind is minimized

Kite can be pulled in with a minimal effort, using
only a small fraction of the energy generated in
the traction phase
At minimal length: new traction phase starts

MAIN PROBLEMS
●
Complexity of the KitVes system makes an exhaustive system
analysis rather difficult
●
Different methods have to be applied in a short period
●
Linguistic and professional diversity within the project:
Conceptual understanding of the system and its elements widely
differs

CONCLUSIONS
●
●
DeCoDe+X
● supports a consistent description of complex systems
● fosters a standardized input and output for quality methods
● links quality methods for the demand compliant product development
● relieves the developer
● generates valid data and documents the system modeling in a
comprehensible way
Success of the method strongly depends on the quality of the maintained
data.
Applied methods are significantly improved in their efficiency and
effectiveness.
