Abstract:
1. A combined offshore system for generating electricity, comprising: an offshore windmill unit with a generator configured to extract power from wind and transfer the extracted power into electricity; an electricity export cable connected to the windmill unit to export produced electricity to offshore or onshore consumers; and at least one offshore wave power unit configured to extract power from waves, electricity produced by the offshore wave power unit being transferred via the same electricity export cable as the electricity generated by the windmill unit, the offshore wave power unit being connected to the windmill unit via a wave power electricity cable that is connected to an electricity converting system of the offshore wave power unit, the electricity converting system converting mechanical energy produced by the wave power unit into electricity exported via the electricity export cable, the electricity converting system being placed within the windmill unit, wherein a horizontal distance between the windmill unit and the offshore wave power unit with respect to the seabed is at least 5 m, and the windmill unit is a structure that is fixed into the seabed.
