Dockwise Vanguard is a semi-submersible heavy transport vessel (SSHTV) built by Hyundai Heavy Industries (HHI) in Ulsan for the Dutch shipping company Dockwise. DOCKWISE VANGUARD is the largest heavy lift vessel in the world.
The vessel has left the yard of Hyundai Heavy Industries ("HHI") on 1. of February 2013 and started its maiden trip. DOCKWISE VANGUARD will sail to the Samsung Heavy Industries ("SHI") yard in Korea to pick up the giant hull of the Jack / St Malo semi-submersible floating production facility for transportation to the US Gulf of Mexico. DOCKWISE VANGUARD was also contracted to transport the GOLIAT FPSO to northern Norway and the AASTA HANSTEEN spar platform to the Norwegian Sea.
DOCKWISE VANGUARD leaves HHI-Shipyard for its maiden voyage
First steel was cut for the giant in September 2011. The keel laying ceremony took place in December 2011. Large pieces of steel were manufactured at the factory and shaped, before being transported to different construction yards for assembly into blocks. The blocks were then shipped to the building dock. The ship was built using 241 blocks and 558 sub-blocks. The first block was placed in the dry-dock at the HHI yard in February 2012. About 50 blocks were placed by March 2012. Winches were supplied by Kraaijeveld. DOCKWISE VANGUARD features a bow-less design developed by Dockwise and Delta Marine. The crew accommodation, including the lifeboats section, is on the starboard side of the vessel. The design allows the flow of water along the entire deck, but prevents the entry of water into the enclosures of the vessel. The ship is equipped with movable casing. A bulwark is also incorporated into the design to ensure the safety of the crew. Machinery exhausts are based on the towers at the port and starboard sides at the stern.
The giant carrier has an overall length of 275m, moulded breadth of 70m, depth of 15.5m and a submerged draft of 31.5m. The deadweight of the vessel is 117,000t. The ship is provided with a free deck space of 275 x 70m. The loading deck extends the entire length of the vessel. She can take loads up to 100,000 t. The ship was classified with a heavy lift vessel notation and categorised as a 'Type 0' vessel. The semi-submersible heavy lift ship can be ballasted down to allow the cargo to be floated aboard. The ballast tanks are then de-ballasted to raise the deck over the water surface for lifting its cargo. DOCKWISE VANGUARD can transport large FPSO vessels, drilling rigs or heavy platforms.
DOCKWISE VANGUARD takes deckloads up to around 100,000t.
DOCKWISE VANGUARD is powered by four Wartsila main engines driving two controllable pitch propellers (CPP). The propulsion system includes two retractable thrusters and one bow thruster for high manoeuvrability. The vessel is also equipped with a reduction gear system. Shipboard power is supplied by one Wartsila 6L20 auxiliary engine. The propulsion system provides a maximum speed of 14kn.
The investment for the vessel reached $240m which is being paid through installments. The project was financed by Dockwise through a rights offering and debt facility. Funding was secured from ABN AMRO, Royal Bank of Scotland (RBS) and the Deutsche Bank.
