UCC divers were utilized to place bagged sand/cement under and around an exposed 24 inch concrete coated steel pipeline then covering the area with 12 inch crushed rock to within less than 2 feet of the original sea bed elevation. UCC provided large marine equipment including a barge with a 400 ton ringer crane and deck space for materials, an ocean going tug, live-aboard vessels, and hopper barges for rock.

All work was performed “around the clock” until the required (diver assisted) placement of 860,000 pounds of bagged sand/cement was accomplished. Additional twelve hour shifts were continued for the crane placement of 3,000 tons of crushed rock.
