A quick sanity check of how the new valve arrangement will fit in the allocated space evacuated by the existing valve, was done through the use of cloud scan. In this simulation walk around in the cloud scan, the existing valve has been removed and the scanned in replacement in the vicinity of candidate area, has been manoeuvred in its please for clash and sanity check and to generate list of design check list to allow for detail design to be formulated. This is done using scanned in component without the needs to do the labour intensive CAD laydown of existing layout and the new valve. For walking in the cloud of the existing system, refer to 3816 Sedco 704 Site Survey for HP Mud Pump Relief Valves Upgrade. For general walk around on site of machinery arrangement, refer to 3816-2 Sedco 704 HP Mud Pump Relieft Valve Change Out Survey Headcam Video. The resultant simulation / sanity check will be used as briefing for designer i.e. reality design and installer ahead of the actual physical works on the rig itself.
