Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deployer of a towing system for towing a streamer used for exploration of marine resources in the ocean and the like, and a charging and discharging device of the towing system.

[0002]

2. Description of the Related Art When exploring marine resources in the ocean, it is necessary to arrange a plurality of exploring streamers at predetermined intervals and to carry out a cable to a position not affected by a mother ship such as an exploration ship. However, their cable lengths and streamers can be hundreds of meters.

[0003] Such an observation system is disclosed in JP-A-9-7.
No. 1291 discloses a ship-loading and unloading device and a deployer for a marine vessel, but the cable, deployer, and a plurality of streamers are connected and disconnected on the deck of the ship and suspended on the sea and underwater. ). The conventional procedure is shown below.

[0004] First, at the time of loading, since a plurality of streamers are stored in a series of lengths in a poop drum, the streamers are loaded into the sea or underwater. When the connection between the streamers is inserted up to the deployer section, attach a stopper to the end of the streamer that has been put into the sea or into the water, and remove the connection between the streamers. The stopper is used as a retainer because tension is generated in the streamer by the fluid force during towing. After that, the input streamer is manually connected to the deployer.

The above operation is repeated to connect the next streamer to the expander. After the connection of the expander of the streamer is completed, the cable and the expander are connected, an operation check is performed, the expander is put into the sea or underwater, the cable is fed out to a predetermined position, and the loading operation is completed.

[0006]

However, according to the prior art having the above-mentioned structure, a plurality of streamers connected in series are electrically and mechanically connected to the cable manually after the expansion, which requires a large amount of time. And the need for labor. In addition, each connection requires checking the operation of various built-in sensors.

[0007] Further, there is a problem that there are places where work is manually performed and the work involves danger. In view of the above problems, the present invention has a configuration in which a plurality of streamers are electrically and mechanically connected in parallel to a cable in advance, and a configuration is provided in which these are recovered in a stepwise manner together with the hull. The aim is to eliminate manual work and to significantly reduce the time, effort and danger in the deployment.

[0008]

In the deployer of the present invention, the connection operation on the deck is limited to the connection operation for connecting a cable, a branching portion connecting a plurality of streamers, and a marine vehicle. Therefore, a dangerous connection operation between the cable to which the foregoing tension is applied and the plurality of streamers is eliminated, and the plurality of streamers can be charged and recovered at the same time, so that the time and labor can be significantly reduced. Further, since the cable and the streamer are electrically connected, an electrical check at the time of connection is not required.

Next, a loading / unloading device of the towing system of the present invention corresponding to a plurality of streamers will be described. The winding machine of the loading / unloading device of the conventional towing system has a cable, a first streamer, a second streamer,...

If the deployer of the present invention capable of separating the fork and the hull is accommodated in a conventional winder, the fork and the streamer are wound and stored on the upper layer of the cable. And the connection between the branch and the streamer are easily damaged. Further, the cable and the streamer have flexibility to be wound on the drum, but since the branch portion is a rigid body, the cable and the streamer are easily damaged by the pressing force on the drum caused by tension at the time of winding.

Further, regarding the winding of the streamer, the rigid portion of the branching portion is wound on the drum, so that the drum has an uneven shape. Therefore, it is difficult to wind the streamer in a line, and the harmful effect of the streamer due to random winding. Occurs. In addition, in terms of maintenance, multiple streamers are disturbed and wound, so even if you want to take out one streamer, you need to extend and deploy multiple streamers, and it takes time, labor, and multiple streamers. There are many problems such as securing space.

There has been no example in the past of a winder for accommodating the above-described branch portion of the expander, a cable connected thereto, and a plurality of streamers. The winding machine of the loading / unloading device of the towing system according to the present invention employs a double drum structure, winds a cable around the inner drum, provides a branch holding portion between the outer drum and the inner drum, and fixes the branch. And wind the streamer around the outer drum. Further, the outer drum is provided with a winding frame so that a plurality of streamers can be separated and wound. Therefore, damage to the cable and the streamer due to winding of the branch and damage to the connection with the branch are eliminated. In addition, since a structure in which a plurality of streamers can be divided and wound can be prevented, the streamers can be prevented from being randomly wound and the streamers can be prevented from being damaged. Furthermore, since even one streamer can be taken out from the winding machine, maintainability is improved.

Next, a description will be given of a transversal machine of the loading / unloading device of the towing system according to the present invention, which supports a plurality of streamers. In the conventional loading and unloading device, a cable, a first streamer, a second streamer,..., An n-th streamer are sequentially connected to a winch drum and stored in a winch drum. All I had to do was to guide the machine to the winding line.

In order to guide the expander capable of separating the fork and the hull of the present invention, the cable connected thereto and a plurality of streamers to the prior art winder, the following compact and multifunctional transversal machine is used. Machine developed. The transverse machine of the loading / unloading device of the towing system of the present invention is provided with a cable, a branch, and a roller platform for a cable, a branch, and a plurality of streamers on a horizontal platform that assists in winding a plurality of streamers. ,
By rotating the horizontal advancing table, it is possible to select a roller table to be wound.

[0015] Therefore, although one horizontal machine, the cable,
The branching section and multiple streamers can be guided to the winder,
It has a multifunctional and compact shape.
