Giant ‘Pieter Schelte’ Caught on Camera [VIDEO]

Some new video posted to Youtube gives us a rare look at the massive Pieter Schelte, a unique catamaran-like vessel that will soon be used to remove decommissioned oil rigs in the North Sea.

The footage was recently filmed during sea trials near the Daewoo Shipbuilding and Marine Engineering shipyard in Okpo, South Korea, where the ship is being built for the Swiss-based offshore pipe installation and subsea construction company, Allseas Group.

Pieter Schelte is a single-lift platform installation and decommissioning vessel particularly suited for the removal of large steel jacket-based platforms in the North Sea. It will measure 382 meters long by 124 meters wide and features a 58 meter-wide slot at the bow where horizontal lifting beams will be capable of lifting topsides and jackets up to 48,000 tonnes and 25,000 tonnes, respectively. As you can see in the video, the vessel appears to be nearly fully ballasted, but when in use it will have an operating draft ranging from 10 to 25 meters (32 to 82 feet).

DSME has been building the ship for Allseas since 2010, but its concept dates back to 1987 when it was first developed by Allseas founder Edward Heerema, who has described the project as the biggest bet of his career (it has been rumored to cost $3 billion). Allseas is even already planning a second, larger ship with a lifting capacity up to 50% greater.

So far, footage of the giant Pieter Schelte has been rare and this is the first known video of the ship at sea. Later this year, however, it will be moved to Rotterdam where finally assembly will take place, so something tells me we are about to be seeing a lot more of this thing.

Check out the video of the ship is below:

Bloomberg spliced a bit of video together to show how she works, check it out here:
