Two ballast water management systems win approval from UN eco committee
THE ClearBal ballast water management system (BWMS) submitted by Denmark has been granted "basic" approval at the 70th Session of the International Maritime Organisation's (IMO) Marine Environment Protection Committee (MEPC 70), while final approval was granted for South Korea's ECS-HYCHLORTM system.
The ClearBal system employs a solution of two active substances, which are injected by a dosing pump and a control unit that adjusts the amount of the biocide injected into the ballast system suction pipeline based on the flow rate measurement recorded by a flow meter. Treatment requires a minimum 24-hour holding time in ballast tanks, reported London's Tanker Operator.
The ECS-HYCHLORTM system filters ballast water to remove organisms and suspended matter larger than 75 祄. The filter unit is bypassed during de-ballasting.
The committee also said that four additional BWMS were granted type approval in accordance with the G8 Guidelines for BWMS. This brings the current number of IMO type approved BWMS to 69.
