Semi Submersible Ship

During my last ship, one of the best thing was to see the installation of new topside platform at the Baronia oilfield but I just can see from afar because no any movement and other operation allowed within 500 meter zone. This operation only can be done by special purposes for the topside operation.  This topside was delivered by Xiang Rui Kou (XRK), semi-submersible vessels from Hyundai Heavy Industries, Korea. The vessel will remove the sea-fastening, de-ballasted and maneuvered in between the jacket (sub-structure) in DP mode. As soon as the vessel is exactly in the correct position, the vessel will ballasts quickly bringing the topside in contact with the jacket and put on top of the jacket. When the topside already on top of the jacket, with sufficient gap between the vessel and topside. Then the vessel will maneuver out of the jacket. Within 7 hours, one new big platform established at this oilfield and it was really amazing.
