Embodiment Construction

[0085] figure 1 A system for handling reels 1 in general and in particular for transporting reels 1 between an auxiliary structure 2 and a laying vessel 3 is shown. More specifically, the system according to the invention is designed to transfer a reel 1 wound with a ribbon 4 for forming a subsea pipeline (not shown in the figure) from an auxiliary structure 2 to a laying vessel 3 and to unwind the The wound reel 1 is transferred from the laying vessel 3 to the auxiliary structure 2 . Reference numeral 1 designates a wound and a fully or partially unwound reel.

[0086] exist figure 1 In the layout of , the auxiliary structure 2 is a floating auxiliary structure, preferably a barge, which is equipped with buffers and is towed on one side next to the quay 5 and on the other side next to the laying vessel 3 .

[0087] The auxiliary structure 2 has a platform 6 supporting a winding station 7 for winding the strip 4 on the reel 1; an assembly line 8 for assembling the strip 4 o...

Abstract

A system for handling reels (1) for laying elongated members on the bed of a body of water, and in particular for transferring reels (1) between an auxiliary structure (2) and a laying vessel (3), has a bridge (13) designed to connect the auxiliary structure (2) and the laying vessel (3); and actuators (14) for moving a reel (1) along and resting on the bridge (13).

Description

technical field [0001] The invention relates to a system for handling reels for laying elongated members on a water bed of a body of water. [0002] More specifically, the invention relates to a system for transporting reels of the above type between an auxiliary structure and a laying vessel next to the auxiliary structure. Background technique [0003] The present invention generally relates to the laying of elongated members on the water bed of a body of water by a laying vessel. The elongated member, in this case a subsea pipeline or cable, consists of strips each wound on a reel and gradually unwound from the reel starting from an unwinding station on the laying vessel around and lay on the water bed of the body of water as the laying vessel moves forward. One of the most critical aspects of this laying technique is feeding the strip to the laying vessel once the reel is unwound. [0004] With the spool installed in a fixed position on the laying vessel and the webbi...
