A ballast water management system (BWMS) capable of treating all water qualities at 250 m3/h will serve an Antarctic vessel.

Trojan Marinex’s skid-mounted Trojan Marinex BWT 250 will be fitted on a next-generation Antarctic Supply and Research Vessel (ASRV) to be used by the Australian government.

Damen Green Solutions recommended the BWMS to Damen Schelde Naval Shipbuilding (DSNS), which is responsible for the design and engineering of the project.

Bespoke design

“At Damen Green Solutions, we partnered with Trojan Marinex to design a ‘plug-and-play’ installation for DSNS,” said Stefhan van Esch, design & proposal engineer at Damen. “Together we created a bespoke design that mounts the entire BWMS on a 3m by 1m skid that can be easily and quickly fitted into the available footprint in the engine room.”

The BWMS requires 14kW of power and was picked partly for its low power draw and ability to operate efficiently in extremely cold water, with 100% operational effectiveness in water temperatures down to –2°C.

It doesn’t use chemicals or generate by-products and is designed to be non-corrosive to minimise maintenance.

Low UV transmittance

With a compact design, the BWMS accounts for the limited space onboard the ASRV.

It uses UV lamp technology with low UV transmittance, compact piping design, post-treatment automation and streamlined cable management.

Construction of the 160m ASRV began in May at Damen Shipyards Galati. The BWMS will be delivered to the yard in August for installation later in 2017.

The vessel is expected to be operational in 2020.
