Способ выполнения высокой опоры морских ВЭУ с высокими башнями включает изготовление опоры на берегу в благоприятных условиях (в специальном бассейне или доке) с платформой 1 в виде понтона с опорными колоннами 2, состоящими из нижнего 3 и верхнего 4 замкнутых полых герметичных отсеков и направленными вверх, с обеспечением плавучести опоры. Затем после заполнения бассейна или дока водой опора всплывает и ее транспортируют на плаву по морю в таком положении при помощи транспортного средства 5 к месту установки, после чего нижние отсеки 3 опорных колонн 2, расположенных с одной стороны платформы 1, заполняют балластом 6, с поворотом платформы 1 и направлением опорных колонн 2 вниз в сторону морского дна 7, затем заполняют балластом 6 нижние отсеки 3 остальных опорных колонн 2 и выравнивают платформу 1, равномерно заполняют балластом 6 верхние отсеки 4 опорных колонн 2 с опусканием опоры и опиранием ее на морское дно 7, далее заполняют балластом 6 внутреннюю полость 8 понтона. A method for making a high support for offshore wind turbines with high towers includes making a support on the shore in favorable conditions (in a special pool or dock) with a platform 1 in the form of a pontoon with support columns 2, consisting of the lower 3 and upper 4 closed hollow sealed compartments and directed upwards, providing the buoyancy of the support. Then, after filling the pool or dock with water, the support floats up and it is transported afloat by sea in this position using a vehicle 5 to the installation site, after which the lower compartments 3 of the support columns 2 located on one side of the platform 1 are filled with ballast 6, with a turn platform 1 and the direction of the support columns 2 downward towards the seabed 7, then the lower compartments 3 of the remaining support columns 2 are filled with ballast 6 and platform 1 is leveled, the upper compartments 4 of the support columns 2 are evenly filled with ballast 6 with the lowering of the support and its resting on the seabed 7 , then the internal cavity 8 of the pontoon is filled with ballast 6.
Количество опорных колонн 2 может быть три и больше. The number of support columns 2 can be three or more.
Балласт 6 может выполняться из бетона, грунта или др. Ballast 6 can be made of concrete, soil, etc.
После транспортировки опоры на плаву к месту установки при заполнении балластом 6 нижних отсеков 3 опорных колонн 2 (или одной колонны 2), расположенных с одной стороны платформы 1, под действием веса балласта 6 образуется вращающий момент, который поворачивает платформу 1 на угол
около 180° до достижения платформой 1 устойчивого положения с направлением опорных колонн 2 вниз в сторону морского дна 7. After transporting the support afloat to the installation site, when the 6 lower compartments 3 of the support columns 2 (or one column 2) located on one side of the platform 1 are filled with ballast, a torque is generated under the action of the weight of the ballast 6, which turns the platform 1 by an angle about 180 ° until the platform 1 reaches a stable position with the direction of the support columns 2 down towards the seabed 7.
В случае транспортировки в неблагоприятных условиях значительного волнения моря, большой скорости ветра опору с платформой 1 в виде понтона с опорными колоннами 2, состоящими из нижнего 3 и верхнего 4 замкнутых полых герметичных отсеков, изготавливают на берегу в благоприятных условиях в бассейне или доке в горизонтальном положении. После заполнения водой бассейна или дока опора всплывает и ее транспортируют в таком положении на плаву с двумя опорными колоннами 2, направленными горизонтально и частично погруженными в воду, при помощи транспортного средства 5 к месту установки, после чего нижние отсеки 3 этих двух опорных колонн 2, заполняют балластом 6 с поворотом платформы 1 и направлением опорных колонн 2 вниз в сторону морского дна 7, далее, как указано выше, заполняют балластом 6 нижние отсеки 3 остальных опорных колонн 2, равномерно заполняют балластом 6 верхние отсеки 4 всех опорных колонн 2 с опусканием опоры и опиранием ее на морское дно 7, затем заполняют балластом 6 внутреннюю полость 8 понтона. In the case of transportation in unfavorable conditions of significant sea waves, high wind speed, a support with a platform 1 in the form of a pontoon with support columns 2, consisting of lower 3 and upper 4 closed hollow sealed compartments, is made on the shore in favorable conditions in a pool or dock in a horizontal position ... After filling the pool or dock with water, the support floats up and is transported in this position afloat with two support columns 2 directed horizontally and partially submerged in the water, using a vehicle 5 to the installation site, after which the lower compartments 3 of these two support columns 2, filled with ballast 6 with the rotation of the platform 1 and the direction of the support columns 2 downward towards the seabed 7, then, as indicated above, the lower compartments 3 of the remaining support columns 2 are filled with ballast 6, the upper compartments 4 of all support columns 2 are evenly filled with ballast 6 with the lowering of the support and resting it on the seabed 7, then fill the inner cavity 8 of the pontoon with ballast 6.
После транспортировки опоры на плаву к месту установки при заполнении балластом 6 нижних отсеков двух опорных колонн 2 под действием веса балласта 6 образуется вращательный момент, который поворачивает платформу 1 на угол около 90° до достижения платформой 1 устойчивого положения с направлением опорных колонн 2 вниз в сторону морского дна 7.
After transporting the support afloat to the installation site, when the 6 lower compartments of the two support columns 2 are filled with ballast, under the action of the weight of the ballast 6, a torque is generated that turns the platform 1 by an angle of about 90 ° until the platform 1 reaches a stable position with the direction of the supporting columns 2 down to the side seabed 7.

A method of performing a high support for offshore wind power plants (WPP) with high towers, consisting of a platform and support columns installed around the platform perimeter, including the installation of a support in the coastal zone, transportation of the support and its installation on the seabed, characterized in that the support platform is performed in the form of a pontoon with support columns, consisting of the lower and upper closed hollow sealed compartments and directed upwards, the support is transported in this position afloat to the installation site, after which the lower compartments of the support columns located on one side of the platform are filled with ballast with the platform rotation and with the direction of the support columns down to the sides of the seabed, then fill the lower compartments of the remaining support columns with ballast and level the platform, evenly fill the upper compartments of the support columns with ballast with lowering the support and resting it on the seabed, and then fill the inner cavity of the pontoon with ballast.
2. Способ выполнения высокой опоры морских ветроэнергетических установок с высокими башнями по п.1 отличающийся тем, что платформу в виде понтона с опорными колоннами, состоящими из нижнего и верхнего замкнутых полых герметичных отсеков, выполняют в горизонтальном положении, транспортируют опору в таком положении на плаву с двумя опорными колоннами, направленными горизонтально и частично погруженными в воду, к месту установки, после чего нижние отсеки этих двух
опорных колонн заполняют балластом с поворотом платформы и направлением опорных колонн вниз в сторону морского дна.
2. A method of performing a high support for offshore wind power plants with high towers according to claim 1, characterized in that the platform in the form of a pontoon with support columns, consisting of the lower and upper closed hollow sealed compartments, is performed in a horizontal position, the support is transported in this position afloat with two supporting columns directed horizontally and partially submerged in water to the installation site, after which the lower compartments of these two the support columns are filled with ballast with the platform turning and the direction of the support columns downward towards the seabed.
