on may 22, no. 2 308,000dwt vlcc built by dsic for landbridge group was officially signed and delivered. the representatives of dsic, landbridge group, bnp paribas and cstc signed on the delivery certificate. yao weixin, president of landbridge group, yang zhizhong and zhang yuhuan, leaders of dsic, and directors of relevant departments attended the ceremony. ms ye fang named the ship "landbridge wisdom".
this ship is a new generation of highly competitive brand ship independently developed by dsic. the ship is 332.95 meters long, 60 meters wide, 30 meters deep, and has a maximum carrying capacity of 308,000dwt. it belongs to the ship type of unlimited navigation area, with a range of more than 25,000 nautical miles. at the design draft of 20.5 meters, it can normally carry 2 million barrels of crude oil through malacca strait.
the ship is equipped with a new desulfurization device, which can effectively reduce the discharge of sulfide during the voyage. the rudder blade is equipped with a rudder ball, and the energy-saving cutting guide wheel is installed on the stern tube in front of the propeller. the energy-saving characteristics of this ship are very significant. the excellent hull curve matches with more energy-saving g-type main engines and a new large-diameter high-efficiency propeller, and is equipped with a high-efficiency energy-saving combination device before and after the propeller with independent intellectual property rights. the sea test shows that the ship has a good energy-saving effect, which is superior to the technical indicators required by the design and reduces a lot of operating costs for the shipowner.
during the construction of the ship, dsic has made great progress in construction accuracy and quality index by summarizing the experience of building series of ships, scientific management and lean production constantly. the installation of desulfurization device was successfully completed in just over 60 days, and the regional integrity of the engine room reached a new high.
the engines are in the condition for operation and commissioning, the boilers are in the conditions for ignition and boiling, and the integrity of docking reach a new high for this sery of ships, all of which create favorable conditions for underwater construction.
during the trial voyage, the ship successfully completed the run-in and remote control of main engines, unmanned engine room, power loss test, start of paralyzed ship, anchor dropping test, ballast water treatment and other projects. it is worth mentioning that the ship experimentally measured the speed in deep sea area, during which all the ship's indicators and system operation met the navigation requirements, and was praised by the shipowner.
