Description

Изобретение относится к области судостроения.The invention relates to the field of shipbuilding.

Известно якорное устройство буровой плаву-. чей установки, содержащее фермы, шарнирно закрепленные на корпусе плавучей установки, клюзы с якорями, причем фермы имеют поплавки и привод перемещения [1].Known anchor device for floating. whose installation, containing trusses pivotally mounted on the body of the floating installation, closures with anchors, and trusses have floats and a displacement drive [1].

Известное якорное устройство требует больших затрат времени на постановку плавучей г установки на точку бурения.Known anchor device requires a lot of time to set the floating g installation at the drilling point.

Целью изобретения является сокращение времени постановки плавучей установки на точку бурения.The aim of the invention is to reduce the time of setting a floating installation at the drilling point.

Цель достигается тем, что в фермах выполнены направляющие, в которых с возможностью^ перемещения установлены клюзы, кинематически связанные с клюзовыми лебедками, и тем, что привод выполнен в виде силового гидроцилиндра.The goal is achieved by the fact that the trusses are made with guides in which, with the possibility of movement, clams are installed kinematically connected with clams winches, and the drive is made in the form of a power hydraulic cylinder.

На фиг. 1 изображена оконечность судна с ,θ якорной установкой, закрепленной по-походному в плане; на фиг. 2 - оконечность судна с якорной установкой с откинутыми связямифермами.In FIG. 1 shows the tip of a vessel with, θ, an anchor unit, fixed in a stowed path in plan; in FIG. 2 - the tip of the ship with the anchor installation with open links farms.

Якорное устройство буровой плавучей установки содержит фермь! 1, шарнирно закрепленные на корпусе плавучей установки 2 и имеют поплавки 3 и привод перемещения, выполненный в виде силового гидроцилиндра 4 для установки ферм в рабочее положение. В фермах выполнены направляющие 5, в которых с возможностью перемещения установлены клюзы 6 с якорями 7 и кинематически связаны с клюзовыми лебедками 8, посредством тросов 9, заведенных за лебедку 8.An anchor device of a floating drilling rig contains a truss! 1, pivotally mounted on the body of the floating installation 2 and have floats 3 and a displacement drive, made in the form of a power hydraulic cylinder 4 for installing the trusses in the working position. In the farms, guides 5 are made, in which the closures 6 with anchors 7 are movably mounted and are kinematically connected with the closure winches 8, through cables 9, wound behind the winch 8.

Устройство работает следующим образом.The device operates as follows.

Перед постановкой на точку бурения поплавки 3 опускаются на воду, ферму 1 откидывают в положение, перпендикулярное диаметральной плоскости судна посредством силового гидроцилиндра 4.Before setting on the drilling point, the floats 3 are lowered into the water, the truss 1 is tilted to a position perpendicular to the diametrical plane of the vessel by means of a power hydraulic cylinder 4.

Якорные клюзы 6 с якорями 7 перемещают по направляющим 5 на конец фермы 1 и травят якорные тросы 9, опуская якоря 7 на грунт, фиксируя буровую установку.Anchor Clues 6 with anchors 7 are moved along the guides 5 to the end of the truss 1 and the anchor cables 9 are etched, lowering the anchors 7 to the ground, fixing the drilling rig.

После этого якорные клюзы возвращают на палубу, и судно дает ход вперед, потравливая якорные тросы.After that, the anchor wrecks are returned to the deck, and the ship moves forward, using the anchor cables.

Аналогично забрасываются якоря с противоположной оконечности судна.Similarly, anchors are thrown from the opposite end of the vessel.

Такое конструктивное решение позволяет увеличивать разнос якорей и длину связей якорей с судном при ограниченной длине жесткой фермы, которые доставляются к месту заякоривания непосредственно буровой установкой.Such a constructive solution allows to increase the spacing of the anchors and the length of the ties of the anchors with the vessel with a limited length of the rigid truss, which are delivered to the anchoring point directly by the drilling rig.

Данное техническое решение позволяет сократить стоимость буровых работ, так как уменьшается время для постановки на точку, ввиду возможности транспортировки жестких связей посредством самой буровой установки.This technical solution allows to reduce the cost of drilling operations, as it reduces the time for setting on a point, due to the possibility of transporting rigid ties through the rig itself.

Claims

This invention relates to the field of shipbuilding. A crusty floating rig installation device containing trusses hinged on the hull of a floating rig is known, clutches with crust, and the trusses have floats and a displacement drive 1. The known crustal device requires a lot of time for setting the floating rig to the drilling point. The aim of the invention is to reduce the time of setting the floating installation to the bfeny point. The goal is achieved by the fact that the trusses are made in the trusses, in which the gateways, kinematically connected with the hawse, are installed with the possibility of movement, and that the drive is made in the form of a power hydraulic cylinder. FIG. 1 shows the tip of a ship with a crustal installation, fixed in a different way in plan; on fng. 2 - the tip of a vessel with a crustal installation with the mifers folded down. The anchor device of the drilling rig contains trusses 1 hinged on the hull of the floating rig 2 and have floats 3 and a displacement drive, made in the form of a power hydraulic header 4 for placing the trusses in the working position. The trusses 5 are made in the trusses, in which the gateways 6 with the bark 7 are mounted and are kinematically connected with the winch 8 by means of the cables 9 wound up for the winch 8. The device operates as follows. Before being drilled at the drilling point, the floats 3 are lowered into the water, the farm 1 is tilted to a position perpendicular to the diametral plane of the vessel by means of a power hydro-cylinder 4. The anchor lugs 6 with the crust 7 are moved along the guides 5 to the end of the truss 1 and the roots cables 9, lowering the core 7 on the ground, fixing the drilling rig. After that, the crutches have returned to the deck, and the vessel gives a turn ahead, corroded cables. 3 Similarly, the core is dropped from the opposite end of the vessel. Such a constructive solution allows one to increase the spacing of the korea and the length of the connections to the rey with the vessel with a limited length of rigid trusses, which are delivered to the site for coring directly by the drilling rig. This technical solution makes it possible to reduce the cost of drilling operations, as the time for putting on point is reduced, due to the possibility of transporting hard links through the drilling rig itself. Claim 1. Anchoring device of a drilling rig, containing trusses hinged 24 on the hull of a floating rig, clutches with bark, the trusses having floats and a displacement drive, characterized in that in order to reduce the time of setting the floating rig to the drilling point , trusses are made in the trusses in which gates, kinematically connected with gates, are installed with the possibility of movement.

2. A device according to claim 1, characterized in that the drive for moving the trusses is made in the form of a hydraulic power cylinder. Sources of information taken into account during the examination 1. USSR Author's Certificate No. 418371, cl. B 63 B 21/50, 1971.
