Current arrangement in and around the Moon Pool area on Transocean Leader was captured via 3D panoramic colour scanner for subsequent briefing with project team for updating of the CAD general arrangement of substructure, moon pool area for future Tree intervention works and clash check. This walk around shows the existing equipment and machinery layout, arrangement of walkways, BOP carrier / trolley and storage area. The video footage of walking in the cloud scan can then be used by the project team to visualise the space available, confirm existing as built state, establish clash free functional layout future proposal. For surveyor’s headcam video data, refer also to 3950-2 TRANSOCEAN LEADER MOON POOL SURVEY – HEADCAM VIDEO. All of these survey data consisting of laser scan, video footage and 360 photographs are distributed to Transocean and archived in RE Subsea Data and rig general arrangement for current and future projects associated with Transocean Leader Support.
