Put in the protect-ing frame structure of deep water basal disc handle hole mark, wherein T.N. mark and P.N. mark refer to respectively true north and
Platform north are identified, the direction under water for pointing to deep water basal disc.It is to be appreciated that in the mistake for vacantly slinging ROV
Cheng Zhong, need to carry out spacing, the identification of identification information can be conducive to correctly recognizing the position of deep water basal disc diagonally opposed to ROV,
To protect ROV detection work to be normally carried out.
S44：Control the ROV to complete the operation to the handle hole and peep hole of the deep water basal disc to test.Control ROV complete
The operation test of the handle hole and peep hole of paired deep water basal disc, to simulate ROV to the operation in deep water basal disc installation process, from
And ensure ROV deep water basal disc install under water it is smooth.
As shown in fig. 6, step S44 comprises the following steps：
S441：Control loop wheel machine transfers ROV to ground where deep water basal disc, and control ROV, which is opened, is arranged on deep water basal disc
The cover plate of handle hole and peep hole in protect-ing frame structure, and handle hole and peep hole are identified.Specifically, to ROV behaviour
Make hole and peep hole is identified including being known using ROV cameras to the instruction O/S in valve operation hole and the O/S of indicator hole
Not.
S442：Recover to land, the hydraulic torque wrench of marine valve opening door is assembled to ROV mechanical arm by control ROV
On.
S443：Loop wheel machine slings ROV again, and control ROV goes to the handle hole of deep water basal disc, hydraulic torque wrench is inserted and grasped
Make in hole, and after matching operation is completed, extract hydraulic torque wrench.It is to be appreciated that in this process Lv, by ROV
Picture pick-up device checks peep hole, to control the hydraulic torque wrench on ROV to complete matching operation.
S444:ROV is sling again to be put to land, and control ROV unties hydraulic torque wrench from mechanical arm, completes hydraulic pressure
The de-coordination of torque wrench.
S445:Sling and sling ROV again, go to the protect-ing frame structure top plate of deep water basal disc, control ROV uses mechanical closure arm
The handle hole of deep water basal disc and the cover plate of peep hole, complete ROV operation test.It is to be appreciated that after completing step S45,
The connection of ROV, ROV control room, hydraulic power station, folding and unfolding cable winch and generator is removed, ROV detection devices are reclaimed.
In step S4, deep water basal disc is detected by simulating ROV by land, entity ROV is applied into deep water basal disc
ROV test in, to determine whether ROV interfaces reasonable, underwater operation can be smoothly completed, to ensure that ROV can be applied smoothly
Into deep water basal disc under water installation process, it is to avoid because ROV can not be well on installation to deep water basal disc in practical application, influence sea
Aqueous hydrocarbon development process is smoothed out, and then causes project to continue and cost increase.
It is to be appreciated that by carrying out path testings of the land simulation ROV to deep water basal disc, being grasped to the ROV of deep water basal disc
