- Three or more fluke anchors equally spaced
- Anchoring lines connected to the central, rotatable part of the turret
- Counterweights connected to each anchoring line to increase rough weather stability
- Deep sea anchorage (< 3000 m)
The wind pressure on the large propeller and the damping of the anchoring device greatly stabilizes the unit.
- Pitch and roll amplitudes of 2 degrees are not considered to influence the production.
- The unit has a natural period in pitch of 15 s and
21 s in roll
Is designed as an aerodynamic, balanced fold-down mast for easy access and maintenance of the nacelle and propeller blades.
Hight from sea level = 240 meters
Propeller diameter = 380 Meters
Designed on the well proven Ramform hull, modified for the purpose by the same (Ramform) designer. (Patents exist)
The propeller blade is constructed like an airplane wing fitted with actuators and flaps.
- Dimensioned for fatigue loads
- Placed behind the aerodynamic shaped mast
- Easy access for cleaning and maintenance
Total energy consumption for production, including auxiliary systems is totalling 57 KW/kg
- 46 KW/kg for H2 production
- 7 KW/kg for liquefaction to LH2
- 4 KW/kg for production and ships function auxiliary systems
Wind energy is extracted by a 2-bladed propeller with a diameter of 380 m
- Efficiency of 0,47% at wind speed of 11 m/s, including mechanical and other losses
- Optimised turbines from traditional up to 10m/s to 12 m/s increases theoretical energy harvest with > 40%
- Turbunes to be designed with 5% overload
- Fuel cell backup power systems
