Embodiment Construction

[0041] figure 1 The illustrated vessel 1 is provided with a device 2 for deploying an object 3 . The object 3 is connected to the deployment device by cables 4 and 5 . Cable 4 is a load carrying or hoisting cable, while cable 5 is a data and power control cable. The two cables 4, 5 have different flow curves. Such as figure 1 As shown, the cable is free in water and can move relative to each other. There is therefore a risk of the two cables 4 and 5 becoming entangled. Furthermore, when the two cables 4 and 5 move individually through the water, the control of the movement of the object 3 relative to the vessel 1 is compromised.

[0042] exist figure 2 In , the vessel 1 is deploying the object 3b by means of the deployment device 2 . Such as figure 2 As shown, the first and second cables 4, 5 are bound to each other by the binding means. The device may be in the form of a clamp, as will be described below. figure 2 The object 3b shown may be a ProMaster as describ...

Abstract

The invention relates to an apparatus and a method for deployment of an object in a fluid, e.g. the sea, by means of at least a first and a second cable, to be connected to the object, the apparatus comprising winch means for reeling in and out the cables, in order to allow movement of the object with respect to the apparatus, characterised in that the apparatus is provided with a bundling apparatus for bundling the cables, when reeled out, in order to provide a single cable assembly between the apparatus and the object during deployment. The apparatus and the method according to the present invention is not only adapted for bundling cables when reeling out the cables during deployment, but the apparatus and the method are adapted for removing a bundling element from the cables when reeled in during recovery.

Description

technical field [0001] The present invention relates to a deployment device for deploying an object in a fluid, such as the ocean, by means of at least one first and second cable connected to the object, the device comprising winding up and unwinding the cable so that the object can move relative to the device winch device. Background technique [0002] The apparatus and method of the present invention may be used, for example, to deploy objects from a vessel to the seabed. Typically, several cables are used to connect the object to the hull. The first cable is a load carrying cable and the second cable is a data and power control cable. In the present invention, it is aimed at such hoisting cables and control cables. However, it should be noted that the invention can also be used in cases where objects are deployed using three or more cables by employing the basic structure of the device. [0003] When deploying objects in the ocean, the load-carrying cables and data po...
