The international shipbuilding, repair, and conversion group, Damen Green Solutions, has designed a ballast water management system for the Government of Australia’s next-generation Antarctic Supply and Research Vessel. The company recently announced that its solution will use the London, Ontario-based Trojan Technologies’ Marinex BWT 250 to meet the requirements of Damen Schelde Naval Shipbuilding (DSNS), which is responsible for the design and engineering of the project.
Given the requirements of its role and the highly sensitive nature of the environment in which it will be operating, the vessel needs a ballast water management system with specific operational capabilities. These include the ability to operate effectively in very cold waters, to use no chemicals, to generate no by-products and to be as compact as possible given that space is at a premium on this complex vessel.
Following an assessment of the available options, Damen Green Solutions recommended the Trojan Marinex BWT 250. The Trojan Marinex system suite provides compact solutions that deliver both filtration and UV treatment within a single unit. With no chemical inputs they create no by-products and are not subject to corrosion. They are also easy to maintain, and the BWT 250 requires only 14 kW of power.
An additional benefit of the Trojan Marinex system is its ability to operate at 100% effectiveness in water temperatures down to –2°C. Also important is the low UV transmittance, which is vital in the Southern Ocean.
Construction of the 160-metre vessel began in May. The ballast water management system will be delivered later in 2017. The vessel is expected to be operational in 2020.
