This walkthrough video familiarisation footage has been captured during a site visit on-board the Paragon MSS1 Semi-Submersible drilling unit, July 2015. The purpose of this site visit was to glean information for the various work scopes planned to be executed during the 2016 Out Of Service period (OOS). This walkthrough video captures the current arrangement of the existing koomey mix tank and its supporting structure. During the 2016 OOS the koomey mix tank is planned to be extended to meet API regulations. This video will also aid the on shore project team and their contractors during project meeting and briefings.
