Saving money with effective ballast water management
Any solid or liquid brought onboard a vessel to increase stability, maintain stress loads or manoeuvrability is a ballast. Water has become a common ballast as, among other advantages, it can be pumped in and out of tanks with relative ease.
Ballast water management involves various processes, from mechanical to biological in nature. These processes seek to minimize the uptake and discharge of pathogens and harmful aquatic organisms within ballast water.
The cost of a ballast water management system tends to be considerable and can be as high as 4.5 million euros per ship. Finding a cost-competitive, effective and environmentally friendly system does not, however, have to be a troublesome endeavour. Bawat, founded in 2011, is a Danish company offering state-of-the art solutions for the maritime industry and is seeking to aid in the protection of the ecological balance of oceans.
Bawat’s technologies offer ship, port and offshore solutions based on pasteurisation. In ships, Bawat’s ballast water management system can exploit waste energy that is available onboard to treat the ballast water during the voyage itself.
At terminals or ports, multiple ships can be serviced so that individual installations on ships can be avoided: which is a lower cost option for the ship owner. Finally, the offshore approach implements a temporary and mobile treatment concept. Benefits of Bawat systems include easy technology, optimal efficiency, green technology and proven marine components.
The technology is furthermore suitable for essentially any ship type and a majority of sizes.
Since financing is often a key point, Bawat can assist with financing at a competitive level. Their systems have a proven and reliable track record. Bawat’s low-cost and green ballast water treatment technology requires no filters, chemicals or UV lamps. Excluding installation costs, prices were denoted to range from about 150,000 to 350,000 euros in 2018.
