Site survey headcam video captured on board the Helix Seawell during a site survey in the aft engine room. The purpose of the survey was to glean required information to allow prefabrication of any of the 12 sea water cooling pipe spools between the high sea suction to the heat exchanger. The survey also included two pipe spools for the heat exchanger overboard line. The survey was performed with the use of Rig Engineering’s Leica Total Station and ML Tech’s automet™ software to accurately survey and record the flange and pipe as built dimensions. This survey method will allow for prefabrication of the pipe spools and remove the needs for hot work onsite.
