SEMI-SUBMERGED MULTIPLE WIND-TURBINE SYSTEM

摘要

The invention relates to a semi-submerged multiple wind-turbine system for use in offshore wind power production implying that it is a floating system with means to maintain a permanent position at sea. The invention increases the technical and economical feasibility of multiple wind-turbine systems most significantly by the reduction and/or control of the loads or forces on to and within the system with derived advantages on structural induced loadings and cost as a consequence. This is achieved by featuring certain relations between the main elements of the system and featuring certain means of control of the system wherein the distribution of buoyancy and weights which is enabled by among other means the use of compartments in the pontoon structures are of a particular benefit to the system.
