Norway-headquartered Fjord Shipping is to retrofit GEA’s compact UV-based BallastMaster marineX ballast water treatment system to 2010-built, 6,400 dwt oil and chemical tanker Key South
GEA of Germany is one of Europe’s largest suppliers of food processing equipment and has teamed up with Canadian Trojan Technologies to develop the BallastMaster marineX ballast water treatment system. The BallastMaster marineX is designed for a throughput of 150-1,500 m³/hour and is also available in an explosion-proof version. The two-stage system combines mechanical pre-filtration with subsequent treatment of the ballast water by UV-C light.
The BallastMaster marineX system treats the ballast water with a UV transmission value of 44% and does not require chemicals. It is a low power consumption compact design, which requires up to 50% less space than conventional systems, making it suitable for small oil and chemical tankers such as 6,400-dwt Key South.
The BallastMaster marineX uses permanent and self-cleaning 32-μm filtration in the first stage of treatment, followed by a second stage of UV-C radiation from the TrojanUV Solo Lamps. During deballasting, the water bypasses the filtration and is passed through the UV chamber again for treatment. The effective differential pressure controls filter backwash and the integrated, automated cleaning of the quartz cladding tubes enable stable operation and compliance with the IMO-D2 limits.
The GEA BallastMaster marineX has been approved by the International Maritime Organization (IMO) with type-approval G8 and has USCG alternate management system approval for all water qualities: fresh water, brackish water and seawater. The tests were carried out in accordance with the Environmental Technology Verification Ballast Water Protocol of the United States Environmental Protection Agency.
GEA notes that as a supplement to the Ballast Water Management Convention, a series of directives have now been adopted which specify the testing and approval of ballast water treatment plants. At its 71st meeting, the Marine Environment Protection Committee (MEPC) of the IMO adopted transitional rules for the entry into force of the Ballast Water Convention. According to these rules, by 2024 all ships concerned must be equipped with ballast water treatment systems that demonstrably meet the quality standard for treated ballast water D-2 Standard laid down in the Ballast Water Management Convention.
Trojan Technologies owns the Trojan Marinex brand of ballast water treatment systems.
