Abstract

Device for deploying a plate or cap shaped barrier structure in a body of water, e.g. a covering element having a pyramidal shape for collection of oil spill, or deploying a covering element onto an object on the seabed. The covering means (17) is during deployment connected to three or more guiding lines (14A-D) extending from a surface vessel (12) or a similar floating structure and down to a corresponding number of anchoring locations (38). The covering element (17) is slideably connected to the guiding lines (14A-D) in at least three of its corners by slideable locking means (16A-D), whereas the guiding lines (14A-D) extend freely from the slideable locking means (16A-D) up to the surface vessel (12). The guiding lines (14) are individually or in groups adapted for individual recovery or deployment. At least one of the slideable locking means (16) can be locked to a corresponding guiding line (14). At deployment of the covering element, the locking means of the guiding lines may be released by means of remotely controlled grippers.

Description

Device for deploying a barrier structure in a body of water. : int The invention concerns a device for deploying a barrier structure in a body of water, as stated in the introductory part of patent claim 1, especially a device for deploying a cover means of a clothing material on or adjacent the seabed.
Background
In a number of situations there is a need for deploying a cover means of a clothing material on or adjacent the seabed. This can be done to cover oilspill from a subsea oil well, over a shipwreck or an oil pipe. As a result polluting material can be collected before it emerges to the surface and spreads thereover.
It can also be necessary to situate such a covering means on the seabed as a temporary sealing, or as a basis for laying a sealing substance, e.g. sand.
From US-patent 4.421.436 it it known to use a rigid pyramidal structure which can be guided up and down along four guiding lines extending parallel to each other from a floating platform and down to fixed anchoring points at the seabed level. Such a Hftmg/lowering arrangement in most cases does not give the necessary flexibility in positioning the structure. Besides the rigid pyramidal structure can create problems both at storing and lowering. From French patent publication 2.368.581 it is known to use a pyramidal structure of clothing material for static deployment. To support this pyramidal structure, each of the side edges of the pyramid is anchored in evenly spaced positions to repective supporting backstays. Because the backstays extend together to the top of the pyramid, lateral positioning of the covering element in relation to a collection location at the seabed or above it is not possible, as the weights are situated such that the cover opening will collapse in the middle.
Object of the invention The main object of this invention is to provide a device for deploying a barrier structure in a body of water, making it possible to place a covering element of a clothing material, even when the sea is rough, in a desired location on the seabed without substantial difficulty. It is a particular object to utilize a number of hold- down cables for this positioning, using winch equipment onboard a surface vessel or si-milar for simple deplyment and recovery.
A more particular object is to provide a device which makes it possible to locate such a covering element at an arbitrary location on the seabed, e.g. to serve as co- vering of a polluting object, especially for subsequent coverage by a mass, e.g. sand.
The invention
The invention is described in the characterizing part of patent claim 1.
By such a device it is possible to lower and position a covering element, especially an element having a pyrimidal shape, so that it is located in a desired position relative to a location on the seabed, e.g. over a shipwreck. Further- features of the invention are stated in patent claims 2-10.
Example of the invention The invention will be described in more detail with reference to the drawings, where
Fig. 1 shows a perspective view of a device according to the invention connected to surface vessel, Fig. 2 shows a perspective view of an alternative embodiment having a wave compensator which carries the top of a collecting cover,
Fig. 3 shows a lateral view of a device according to the invention during the stage of lowering the cover element, and
Figs. 4a-4c disclose different operative phases in lateral view of equipment for lowering a covering element and subsequent coverage by a mass. In fig. 1 there is shown an operating vessel 12 which transfers fluid to an assisting vessel 11. The operating vessel 12 is provided with equipment for handling and ∞ntrolling a device according to the invention. This equipment comprises a winch means 13 which can deploy and recover four cables 14A-D, singularily or in groups of two. Four separate winches or one winch having four independent drums may be used. Furthermore, the operating vessel 12 is provided with a deployment bar 15 having rollers for guiding the equipment to be deployed. The equipment corresponds to that which is used for deploying trawls. Each of lines 14A-D is taken to an anchor 38 which is constructed to take hold in the seabed. The anchors 38 can be constructed in a per se known manner and be dropped from the operating vessel 12. The lines 14A-D serve as guides for each weight using rollers 16A-D which, in an appropriate manner, are connected to a corner of a covering element 17 having a pyramidal shape. The covering element 17 can be of a flexible, armed clothing material. At the top it is anchored to a top line 18 extending to winch means 13 on the operating vessel 12. The top line 18 simultanously serves as a support for a sucking hose 19 which extends from the vessel 12 down to the interior of the covering means 17. The sucking hose 19 is connected with the top line 18 using evenly spaced slidable dogs.
The covering means 17 is situated over a ship wreck 20 which contains polluting material, e.g. oil or a different material having a lower specific weight than sea water. By drawing and slacking the guiding lines 14A-D, positioning of the covering means 17 can be controlled over a certain area of the seabed. Advantageously, at least one of the running wheels 16A-D is connected to a gripping mechanism which can be controlled from the surface and can lock the running wheel to the corresponding guiding line 14A-D. The conntection between the guiding wheels 16A-D and the covering means 17 can be arranged in a per se known manner. By reference to Fig. 2, a more detailed example of the embodiment of this part of the equipment will be described. In Fig. 2 there is shown a modified embodiment of the invention, where corresponding parts are given the same reference numerals as in Fig. 1. The covering means 17 is used in connection with a pipeline 21, to catching spillage from a leak in said pipeline. To provide access to the pipeline after positioning of the covering means 17, the upper part of one of the side surfaces is provided with an opening 22 which, via a flexible hose 23, is connected to the lower part to the covering means 17. Diving equipment or other necessary treatment equipment can be taken down to the leaking spot th. rαgh this hose. To each weight-loaded guiding wheel 16A-D, elec-romechanically controlled gripping means 24 are provided, whereby the guiding wheel can be locked to corresponding guiding line 14A-D. To controll the grippers 24, a number of electri- cal cables 25 are taken to each gripper through the sucking hose 19. In this way the covering means 17 can be anchored in a certain position relative to the seabed. At reception or movment, the grippers 24 should be free so that the respective guiding wheels 16A-D can move on the guiding lines. Electrical cables 25 can also transfer 5 video signals from one or more video cameras positioned near the equipment. To keep the covering means 17 in a lifted position, this embodiment uses a floating device 26 which is constructed as a wave compensator. The floating device 26 is a hollow body which via a double hose for pressurized gas 27 from the operat¬ ing vessel 12 the content of water, and hence buoyancy can be regulated. The top 10 line 18 is taken through the floating device, preferably by being taken laterally through a radial and axial slot (not shown). In this manner a wave compensator float¬ ing in the water can be connected to a top line already extending from the operating vessel to the covering means 17. The floating device 26 can be anchored to the top . line 18 using a locking mechanism of a per se known type, for example a pneumatic 15 gripper receiving activating energy through one part of the pneumatic hose 27. In Fig.3 there is shown how the covering means 17 can be taken down along the guiding lines 14A-D in a substansially folded arrangement. As shown the covering means 17 takes the form of a folded umbrella with its lower weight-carrying corners being guided along the guiding lines. 20 At the top of the covering means is situated a manifold 28 which at its lower end communicates with the inner part of the covering means 17 and has a lateral opening for the sucking hose 19 at its upper end. The manifold 28 furthermore serves as a connection for the top line 18. In Figs. 4A-C there is shown an alternative embodiment for using the device to 25 deploy a covering over a polluting or a potentially polluting object on the seabed e.g. a wreck of a nuclear submarine 30. Corresponding parts are in this example also given the same reference numerals as in the example of Fig. 1.
The covering means 17 is constructed in a corresponding manner to the example in Fig. 2, namely having an opening connected to a tubing 23. The free end of a hose 30 19 is taken through this tubing 23, the hose being in this case provided for the supply of a covering material e.g. sand.. The lower part 37 of the hose 19 is connected to a carrying frame 31 which can be guided on the guiding lines 14 using a set of guiding wheels 32 in a manner to covering means 17. The two parts are connected during deployment and the first operating stage. The top line 18 is taken down to a releaseable connection point 33 on the top of the covering means through an upward extending bar 34 connected to the carrying frame 31.
In the first operating stage after deployment, a layer of sand 35 is situated over the nuclear waste 30. Following this the covering means 17 is positioned, lowered and released from the guiding lines 14 so that it falls down onto the sand layer 35 over the nuclear waste 30. This release can be arranged by a releaseable, remotely cont¬ rolled connection between the guiding wheels 16A-D and the guiding lines 14A-D. The covering means 17 will be placed evenly and tight over the sand layer 35 as shown in Fig.4B. In this way the device is ready for the next stage as illustrated in Fig. 4C. In this stage, more sand 36 is provided through the hose 19, and is posi- tioned in a layer over the covering layer of the covering means 17.
The device according to present invention can be further modified and used in different ways. The covering means 17 may, during deployment, be provided with a tight locking element or "waist-belt" (not shown in Fig. 3), serving to keep the struc¬ ture together during deployment. This "waist-belt" may, after deployment has been completed, be released so that the covering means can be extended in pyramidal shape over the operating location.
Deployment and use of the device is not limited to vessels floating on water, as it can equally be effected from platforms, from ice-surfaces and in some cases from floats or landbased plants. Such a device can, for instance, be lowered in a quay basin from a landbased crane.
The shape of the covering means 17 can be constructed for different purposes. It can be made with a long basic shape to c ,er a ship wreck. It can also be made in a shape of a tent with a flat roof and double top lines. The equipment necessary to serve and control the different components of the system, e.g. the controlling equipment of the surface vessel may be based on per * known technology and will therefore not be described in more detail.
