On December 4th 2012, CROSS & Auramarine presented with much success the retrofit case of M/V Birka Express, a Finnish Ro-Ro vessel, with Crystal Ballast BWTS.

Crystal Ballast uses filtration and UV radiation to treat ballast water and has received type approval by DNV.

The project took place during a 9-day dry dock of the vessel in Tallinn, Estonia and extensive engineering work, including a 3D scan of the installation space had to be done in advance in order to keep up with the vessel’s schedule.

The whole project was delivered on a turnkey basis and completed in 4 months, with Auramarine engineers having to work overtime to conclude this project on time. All necessary plans and documentation were made by Auramarine:
