MS Ore Brasil, previously known as Vale Brasil, is a very large ore carrier owned by the Brazilian mining company Vale. She is the first of seven 400,000-ton very large ore carriers (VLOC) ordered by Vale from Daewoo Shipbuilding & Marine Engineering in South Korea and twelve from Jiangsu Rongsheng Heavy Industries in China, which are designed to carry iron ore from Brazil to Asia along the Cape route around South Africa. While close to the specifications of Chinamax, these ships are generally referred to as Valemax vessels by Vale. They are the largest bulk carriers ever built.
