This walkthrough video familiarisation footage has been captured during a site visit on board the Transocean Sedco 704 in May 2015. The purpose of this site visit was to glean the as built condition of the BOP wellhead spider frame. The data gathered is intended to be used in the accurate CAD based design process of the future installation of the open water guide cone. Recordings from the Hardhat Mounted Camera provide the viewer with a walkthrough of the wellhead spider frame where the guide cone will connect. This video will also aid the on shore engineering department during the necessary design works. The guide cone previously used on MAERSK Project on sister unit SEDCO 712, will be adapted to suit Sedco 704. For more information relating to this similar implementation of MAERSK guide cone, refer to Video No: 3503-1 SEDCO 712 BOP – MAERSK Components For Assembly Inclusion.
