The above image is not a barge, or a leg-less jack-up rig, but rather the hull of the North Dragon semi-submersible drilling rig under construction at CIMC Raffles. The columns and pontoons have been built separately as the below image shows (shot last October) and were launched in November of last year.
The rig was designed in a joint effort between Global Maritime and CIMC Raffles and will be DNV-GL classed and Singaporean-flagged. CIMC says it was designed in accordance with the North Sea conditions, taking into account the Arctic and Barents Sea conditions with the requirement to withstand a 100-year storm in the North Sea, to meet the Norwegian petroleum authorities, Norwegian Maritime Board and the Norwegian offshore industry standard ( NORSOK ) requirements.
Delivery is planned for 2016.
