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 and condition of the seawater overboard dump piping that terminates at the port intermediate column, it is planned to replace and modify this piping run from the main deck level until its termination above the port intermediate column where it connects to a 8” hose. This replacement is required due to leakages in the pipework. This video will also aid the on shore project team and their contractors during project meeting and briefings.
