AUSTRALIA’S new Antarctic supply and research vessel is to be outfitted with a state-of-the-art ballast water treatment system to meet exacting standers of Damen Schelde Naval Shipbuilding (DSNS), the vessel’s designer and engineer.
The company settled on the Trojan Marinex BWT 250 to take care of ballast water treatment on the vessel, as the unit provides the capability to both filter water and treat it with UV rays. With no chemical inputs, the unit creates no by-products and it can also operate in water temperatures down to -2°.
The choice of ballast water treatment system is particularly important on such a vessel given the arduous conditions it will operate in and the pristine nature of the ocean and ice shelves surrounding the frozen continent.
Damen design and proposal engineer Stefhan van Esch said the shipbuilder partnered with Canada-based Trojan Trojan Marinex to design a ‘plug-and-play’ installation for the project.
“Together we created a bespoke design that mounts the entire BWMS [ballast water management system] on a 3m by 1m skid that can be easily and quickly fitted into the available footprint in the engine room,” Mr van Esch said.
“Prior to leaving the manufacturing works it will undergo a factory acceptance test, leaving DSNS with the simple matter of connecting up the power and the main pipes once it is aboard the vessel. The Trojan Marinex BWT 250 will then be ready to disinfect and treat up to 250m³ of seawater an hour.”
Construction of the 160-metre Antarctic supply and research vessel began in May at Damen Shipyards, Galati.
The ballast water management system is to be delivered to the yard in August for installation later in 2017. The vessel is expected to be operational in 2020.
