Embodiment Construction
[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.
[0027] Such as Figure 1-5 As shown, the present invention is an optical cable laying method for in-situ monitoring of submarine pipelines, and the implementation steps include:
[0028] (1) After the pipe-laying ship 12 is in place, place the take-up and pay-off frame wrapped with the optical cable 4 on the rear side of the stern tensioner 14, and place the cable storage reel wrapped with several sections of optical cable sheath 3 on the take-up and pay-off stand Next, the optical cable fixing device 15 is fixed between the tensioner 14 and the stinger 13, and the steel pipe 1 to be laid is inserted into the center hole of the optical cable fixing device 15 after passing through the tensioner 14;
[0029] (2) Start the optical cable fixing device 15, pull the optical cable 4 and place it on the side of the steel pipe 1, then pull the optical cable shea...
