The vessel is fitted with two passive roll reducing tanks and features a pneumatic bulk handling system that can simultaneously release two types of dry bulk via two individual discharge lines. The continuous bollard pull capacity of the vessel is 190t and the maximum capacity is 205t.
Environmental features include a sewage treatment plant, an oily water separator with 15ppm monitor, ballast treatment system, and a galley macerator. The stern roller is fitted with a freshwater lubrication system. The centre mud tanks, fitted with agitators, are of free flowing design.
The deadweight of the vessel is 3,350t, gross registered tonnage (GRT) is 4,566t and net registered tonnage (NRT) is 1,370t. Her overall length is 86m and length between perpendiculars is 73.5m. Moulded breadth, depth to main deck and design draft are 19.9m, 8.8m and 6.8m respectively.
The contract for the construction of the vessel was signed in May 2007. The keel was laid in October 2009 and the vessel was launched in March 2010. The naming ceremony was held on 11 March 2011 in Hong Kong.
