Blue Marlin Serves as Floating Drydock for SemiSub

Thursday, February 26, 2004
The first job of the recently jumboized heavy transport vessel Blue Marlin is the transport of the the Dai Hung I semi-submersible production platform of VietsovPetro from an offshore location to Hyundai-Vinashin's yard in Nha Trang, Vietnam, where the Blue Marlin will serve as a dry-dock facility. Dockwise was awarded the contract by Hyundai-Vinashin of Nha Trang in Vietnam for the transport and dry-docking of the 13,200 tons semi-submersible production platform Dai Hung I, as no local dry-docking facilities were available. The Dai Hung I was loaded on January 31, approximately 20 miles offshore Nha Trang and transported to the yard. The unit has a length of 108.2 m, a width of 67.36 m and a height of 80 m. As the Dai Hung I has been tranversely positioned on the 63 m wide deck of the Blue Marlin the pontoons of the Dai Hung I created an overhang of 25.7 m to starboard and 19.5 m to port. After completion of dry-docking the Blue Marlin will redeliver the Dai Hung I to it offshore location, which is expected on February 28, 2004. Although the weight of the Dai Hung I did by far not reach the full capacity of the Blue Marlin with a deadweight capacity of 76.061 tons, it is a new milestone for Dockwise. It was the first time ever that this type (Aker H-3) of semi-submersible has been transported or dry-docked by Dockwise. Because the internal structure of this type of unit needs sufficient footprint, it used to be very difficult to dry-transport. But with the increased width of the Blue Marlin to 63 meters, Dockwise is now able to provide an excellent platform for the Dai Hung I or other Aker H-3 types to be transported or dry-docked.
