1. Steamer handling apparatus for use on a seismic survey vessel, the apparatus comprising guide means adapted to be mounted on the streamer deck of the vessel, adjacent the stern end of the streamer deck, so as to extend transversely over at least a part of the width of the streamer deck, and trolley means movable across the streamer deck, the trolley means being adapted to engage the guide means so as to be guided thereby in its movement across the streamer deck, and including a camping device for gripping the inboard end of part of a streamer whose other end is deployed over the stern end of the streamer deck. 2. Apparatus as claimed in claim 1, comprising two of said trolley means, each movable transversely over substantially the whole of a respective half (port or starboard) of the width of the streamer deck. 3. Apparatus as claimed in claim 1 or claim 2, wherein the guide means comprises, for the or each trolley means, a respective guide rail adapted to be secured to but spaced above the streamer deck, the or each trolley means including at least one guide wheel for engaging the underside of the guide rail. 4. Apparatus as claimed in claim 3, in which the or each trolley means includes two of said guide wheels, which are spaced apart in the direction of movement of the trolley means. 5. Apparatus as claimed in claim 3 or claim 4, in which the or each guide rail is disposed between its trolley means and the stern end of the streamer deck for extending streamers. 6. Apparatus as claimed in any preceding claim, for use where the stern end of the streamer deck is provided with a guard rail extending its whole width, in which the or each trolley means includes at least one guide roller which engages the inboard side of the guard rail. 7. Apparatus as claimed in claim 6, in which the or each trolley means includes two of said guide rollers, which are spaced apart in the direction of movement of the trolley means. 8. Apparatus as claimed in any preceding claim, in which the or each trolley means is provided with at least one support wheel which runs on the streamer deck. 9. Apparatus as claimed in any preceding claim, in which the or each trolley means is motor driven. 10. Apparatus as claimed in any preceding claim, in which the or each trolley means is motor driven by means of a respective hydraulic motor which is fixedly disposed at one end of the guide rail of the trolley means and which drives the trolley means via a chain connected to the trolley means. 11. Apparatus as claimed in any preceding claim, in which the or each trolley means includes storage means for storing tools and the like. 12. Apparatus as claimed in claim 11, wherein the storage means comprises at least one drawer. 13. A seismic survey vessel comprising a streamer handling apparatus as claimed in any preceding claim. |
