Vale Company , the world’s largest iron ore producer, is equipping its VLOC ships with Silver Stream bubble propulsion systems to reduce fuel consumption. Steel Price magazine has dealt with this issue in a specialized way, which we will point out in this report. Please be with Artan Press.
*** A major breakthrough in shipping marine mineral cargo
The first Vale ore carrier equipped with an air lubrication system is scheduled to enter Brazilian waters in August. The world’s second-largest method of transporting heavy iron ore is testing a technique developed by British manufacturer Silverstream in which compressors send air to submarines and form a carpet of bubbles that cause friction between the hull and Reduces water. This will be a major development in the shipping of mineral cargo. Its success must be confirmed. The company expects to reduce its greenhouse gas (GHG) emissions from navigation. This technology, known as air lubrication, was installed in the Victorian Sea with a 325,000 ton Bomax ball.
*** Reduce fuel consumption in the new project of Vale Company
The Vale navigation team estimates that if the test is successful, the technology could be replicated in the rest of the contract fleet dedicated to transporting the company’s ore. “Conservative estimates point to a fuel reduction of about 5 to 8%, with a possible 4.4% drop in the annual emission of iron ore waltz. After the recent events,” said Valerie Navigation Technical Director Rodrigo Bermello. , Miners are stepping up environmental, social and governance efforts.
*** Which countries were involved in the construction of the huge Vale project?
This technology is made by the English manufacturer Silverstream. Vale Mine developed the project in partnership with ITV (Vale Technology Institute) and Korean ship owner Pan Ocean to install the technology on one of the VLOCs (very large ore carriers) dedicated to transporting Vale ore. . The Shanghai Ship Design Research Institute (SDARI) was responsible for designing the ship and integrating it with the bubbles. Chinese shipbuilding company New Times Shipbuilding prepared the ship during construction and installed equipment at the Yiu Lian Dockyards (Shekou) LTD shipyard in Shenzhen, China. The installation took 35 days and the ship was ready on June 28
*** Reduce greenhouse gas emissions in Vale Company project
The approval of air lubrication is part of the Vale´s Eco-shipping program, which is designed to meet the challenge of reducing the company’s carbon emissions, in line with what is being discussed in the field of the International Maritime Organization (IMO). Last year, the company announced plans to increase its direct and indirect emissions (project areas in phases 1 and 2) by 2050, and also reduce emissions by 3% by 2035 by 2035. . From Transportation Because the company contracts ships from third parties to transport its ore. The Vale reduction targets will be met in accordance with the Paris Agreement.
Earlier this month, Vale also signed a MOU with 23 other companies to begin studying the use of ammonia as an alternative marine fuel. In addition, the company is preparing to use alternative fuels. Dozens of second-generation VLOCs in operation are designed for future installation of liquefied natural gas (LNG) systems, including a basement compartment for tank storage. Ecoshipping is developing a multi-fuel tank that will be able to store and consume not only liquefied natural gas (LNG) but also methanol and ammonia in the future.
*** A big change in the future of the mining trade
According to Bermello, the use of low-consumption technologies such as rotating sails and air lubrication will reduce fuel consumption on any ship and adopt low-carbon fuels. A preliminary study of Guybamax ships estimates that emissions could be reduced by up to 40 to 80% if methanol and ammonia are supplied, or up to 23% in the case of LNG. By adopting new technologies and modernizing the Vale fleet, the company has invested heavily in incorporating advanced navigation solutions in terms of efficiency and innovation in the environment.
Since 2018, the company has operated the second generation Valemaxes and since 2019 with Guaibamaxes, with a capacity of 400,000 tons and 325,000 tons, respectively. These vessels are among the most efficient vessels in the world and are able to reduce CO2 emissions by up to 41% compared to the large vessels built in 2011 and weighing 180,000 tons. This could dramatically affect the future of the mining trade. Give.
