Pushing the sliding bridge 19 out of the support 18 by the ROV to interface with another support 18 as a moving track for the sliding carriage 60; the sliding bridge 19 is located directly below the sea pipe 1. The ROV then inserts a hot stab (hydraulic quick connector) into the interface on the control panel corresponding to the fourth drive mechanism, and the carriage 60 is driven by the fourth drive mechanism to move along the carriage 18 and the sliding bridge 19, and simultaneously moves the lower locking carriage 50 and the lower locking device 4 under the sea pipe 1, so that the position of the lower locking device 4 is aligned with the position of the upper locking device 3. Then the ROV replaces the hot stab with an interface which is inserted into the control panel and corresponds to a first driving mechanism, and the first driving mechanism drives the two pipe clamp brackets 30 to move in opposite directions respectively, so that the pipe clamp body 2 fixed on the first driving mechanism is assembled and covered on the surface of the sea pipe 1, and positioning and mounting of the pipe clamp body 2 on the sea pipe 1 are completed.
After the pipe clamp body 2 is positioned and installed, the ROV continues to replace the hot stab and sequentially inserts the interface corresponding to the second driving mechanism and the interface corresponding to the third driving mechanism on the control panel, the second driving mechanism drives the upper locking support 40 to move downwards to cover the upper end of the pipe clamp body 2, and the third driving mechanism drives the lower locking support 50 to move upwards to cover the lower end of the pipe clamp body 2. Finally, the upper locking device 3 and the lower locking device 4 are locked on the pipe clamp body 2, and the installation device can be recovered after the completion.
When the installation device is recovered, first, the ROV removes the bolts fixed between the pipe clamp body 2 and the pipe clamp bracket 30, the upper locking device 3 and the upper locking bracket 40, and the bolts 18 between the lower locking device 4 and the lower locking bracket 50 using a torque wrench, thereby completing the separation of the installation device and the pipe clamp. The ROV operator control panel then performs the counter-action of the installation action to restore the pipe clamp bracket 30, upper lock bracket 40, lower lock bracket 50, and sliding bracket 60 to the pre-installation state. The ROV then operates the control panel to extend the support legs 12 on the frame 10 to adjust the height of the frame 10 completely away from the lost circulation pipe clamp. And finally, hanging the installation device away from the seabed by a crane to complete recovery.
