Abstract

Use: for emergency evacuation of personnel from an offshore facility, such as a drilling platform. SUMMARY OF THE INVENTION: an evacuation system from an offshore object comprises an arrow made of articulated sections, pivotally mounted for rotation in the vertical and horizontal planes, hydraulic actuators for turning the arrows and sections of this arrow relative to each other, and a lifeboat, articulated connected by a detachable member to a boom nose. The boom is made with stops fixed in pairs on sections at each hinge on opposite sides of these sections. When the boom sections are turned to their coaxial position, the stops interact with each other. 4 and / t;

Description

The invention relates to offshore drilling platforms for evacuating personnel from an emergency facility.

The purpose of the invention is to increase safety by maximally removing the boat from an offshore facility and ease of operation by providing the ability to open and fold the articulated boom sections.

In FIG. 1 shows a general view of the system in its initial position; in FIG. 2 - the first intermediate position at the start of the launch operation; in FIG. 3 - second intermediate position; in FIG. 4 - end of the boom sections.

The evacuation system from an offshore facility includes a drilling platform 1, an boom made of a root section 2 pivotally connected to each other, mounted on a platform 1, intermediate sections 3.4 and an end section 5, pivotally connected via a detachable assembly with lifeboat 6. On sections 3.4.5 y

each of the hinge connecting them, stops 7 are installed in pairs, with two stops of each intermediate section 3 and 4 located on opposite sides of its longitudinal axis, and the hydraulic drive of rotation 8 is fixed on the opposite sides. The root section 2 is equipped with a drive of rotation 9 in horizontal and vertical plane x.

In the initial position of the boom section 2,3,4-5 in the folded upright position and the boat 6 in the upper fixed position. When turning on the hydraulic drive 8. the end section 5, connected with the boat b, begins to rotate around the hinge connecting the end section 5 and the intermediate section 4, the boat 6 is removed from the platform 1 and begins to lower.

At the same time, hydraulic actuators 8 are mounted, alternately mounted from different sides at the junction of the sections

boom 2,3,4,5, the boom opens by turning sections around the hinges. If present Interference in the movement of the boat or the need for change. direction of launching the boat, the horizontal boom rotation drive 9 is installed, mounted between the platform 1 and the root section 2, and all boom sections and the boat b are rotated by an angle ensuring safe movement. With full disclosure of the boom sections 2,3,4,5, i.e. turning each section around the hinge by 180 °, the stops 7 are activated, while the boom is locked in the open position.

After opening the boom and lowering the boat b into the water, the boat is separated from the end section 5.

To return the evacuation system to its original position, the boat 6 is fixed to the end sections 5, the hydraulic actuator 8 is turned on and the sections 2,3,4,5 are simultaneously folded by turning around the hinges.

If necessary, the number of collapsible articulated sections can be increased, this will ensure even greater removal of the boat from the object, which is very important in emergency situations at offshore objects.

Claims (1)

Moving the boat to the maximum distance from the platform, quick opening of the boom sections and compact folding of the sections ensures the safety and convenience of the operation of the evacuation system from the offshore facility. Formula of the invention An evacuation system from a marine object comprising an arrow made of articulated root, intermediate and end sections, a hydraulic drive for turning these sections relative to each other, and a lifeboat articulated via a terminal end assembly a section of this boom, the root section of which is connected to the marine object, characterized in that, in order to increase safety and ease of use, the root section is connected to the marine object articulated with rotation in horizontal and vertical planes and is equipped with drives for its rotation in these planes, while the arrow is made with stops fixed in pairs on the sections of each of the hinges connecting them with the possibility of interaction in pairs with the coaxial arrangement of the sections, with two stops each intermediate section is located on different sides from its longitudinal axis.
