Description
Изобретение относитс к морскому нефтегазопромысловому гидротехническому строительству, а именно к проблеме установки на точку бурени опорного морских стационарных платформ, предназначенных дл бурени и эксплуатации MOD- ских иефт ных и газовых скважинThe invention relates to the offshore oil and gas hydraulic engineering construction, in particular to the problem of installation on the drilling point of the fixed offshore stationary platforms intended for drilling and operating MOD oil and gas wells.
Целью изобретени вл етс упрощение способа за счет облегчени условий демонтажа при обеспечении транспортабельности на плаву.The aim of the invention is to simplify the process by facilitating the dismounting conditions while ensuring transportability afloat.

понтонов 3 с помощью лебедок 6 подаетс предварительное нат жение тросам 8. Производитс расстыковка понтонов 3 от опорного блока 1 путем срезки патрубков А и 5. В этот момент понтоны 3, удерживаемые от всплыти тросами 8 и лебедками 6, под действием сил остаточной положительной плавучести из первоначального наклонного положени привод тс в строго вертикальное . Затем к верхним част м понтонов 3 закрепл ютс трос-отт жки 11 от буксиров 10, Всплытие и разворот понтонов 3 в транспортное положение производитс путем стравливани тоосов 8 с одновременным нат жением трос-отт жек 11, св занных с буксирами 10. При этом понтоны 3 привод тс в положение, удобное дл транспортировки , отсоедин ютс тросы 8 от понтонов 3, которые с помощью буксиров 10 транспортируютс на берег дл повторного использовани .the pontoons 3 with the help of winches 6 pre-tension the cables 8. The pontoons 3 are disconnected from the support block 1 by cutting the pipes A and 5. At this moment the pontoons 3, which are kept from ascending by the cables 8 and the winches 6, under the action of residual positive buoyancy forces from the initial tilted position is strictly vertical. Then, the cable delays 11 from the tows 10 are fastened to the tops of the pontoons 3, the pontoons 3 ascend and turn into the transport position by releasing the toos 8 with the simultaneous tension of the cable exits 11 connected to the tugs 10. In this case the pontoons 3 are brought to a position convenient for transportation, the cables 8 are disconnected from the pontoons 3, which are transported by towing towers 10 to the shore for reuse.
Применение способа по изобретению, исключает работы по использованию кранового судна большой грузоподъемности,The use of the method according to the invention, eliminates the work on the use of a crane ship of a large capacity,
