Abstract
Изобретение относитс к морским гидротехническим сооружени м. Целью изобретени вл етс упрощение монтажа. Ледостойка бурова платформа содержит основание 1, колонну 2, верхнее строение 3 с буровым комплексом, ледорезы-пантоны 4 с катками и выкружками-фиксаторами, стальными канатами, подъемным устройством. Дл упрощени монтажных операций и повышени надежности сооружени при установке балластировкой основани 1 с колоннами 2 на место бурени в качестве понтонов дл повышени устойчивости используют ледорезы-понтоны 4, обладающие собственной плавучестью. Затем ледорезы 4 притапливают дл придавливани основани 1 с колоннами 2 и захода плавсредства между колоннами 2, после чего ледорезы 4 поднимают по колоннам 2 дл посадки и фиксации плавсредства. Плавсредство балластируют или дебалластируют совместно с ледорезами при установке верхнего строени на колонны. Ледорезы-понтоны 4 снабжены стальными канатами с подъемными устрйоствами, установленными на колоннах 2, причем одна из наклонных плоскостей обоих ледорезов-понтонов 4 между колоннами 2 снабжена выкружкой-фиксатором, конгруэнтной днищу плавсредства. 5 ил.The invention relates to marine hydraulic structures. The aim of the invention is to simplify installation. The ice-resistant drilling platform contains a base 1, a column 2, an upper structure 3 with a drilling complex, ice-cutters-pantones 4 with rollers and fillets-clamps, steel ropes, a lifting device. In order to simplify installation operations and increase the reliability of the structure, when installing base 1 with columns 2 at the drilling site, use ice-cutters-pontoons 4 with their own buoyancy as pontoons for increasing stability. Then the ice cutters 4 are embedded to press down the base 1 with the columns 2 and the floating craft enters between the columns 2, after which the ice cutters 4 raise along the columns 2 to land and fix the floating equipment. The watercraft is ballast or deallast together with ice cutters when installing the topsheet on the columns. The ice-cutters-pontoons 4 are equipped with steel ropes with lifting devices mounted on columns 2, and one of the inclined planes of both ice-cutters-pontoons 4 between the columns 2 is provided with a fillet fixer congruent to the bottom of the craft. 5 il.
