Japanese shipyard orders 'CleanBallast'
Sumitomo Heavy Industries (SHI-ME) decides for the RWO ballast water
treatment system
received an order for three of its ballast water treatment systems CleanBallast from
the Japanese shipyard Sumitomo Heavy Industries Marine & Engineering Co. Ltd.
(SHI-ME). The shipyard located in Yokosuka, Japan, has built in excess of 1,300
ships. Specialising in medium-sized tankers with high added value SHI-ME has a reputation in the industry as one of the technology leaders. The ballast water treatment
plants of the long-established Bremen company RWO will be installed in 2012 in three
Aframax tankers which will be built for a European shipowner.
The CleanBallast ballast water treatment system, with a maximum capacity of 3,000 m³/h,
will be equipped with several of RWO’s advanced disinfection systems operating in parallel.
This allows the system to cater for differing rates of ballasting and de-ballasting.
"Besides its very low energy consumption, high product quality and simple system configuration, its disinfection performance in low conductivity water without dosing chemicals and
no risk of re-growth of organism during voyage are the reasons SHI-ME decided applying
CleanBallast," says Akihiko Masutani, Project Manager of SHI-ME. “In addition, CleanBallast also works in intermittent operation or even in turbid water and has a number of further positive features" he added. Akihiro Shirai, Deputy General Manager of SHI-ME, says
"RWO's long time experience in the marine water treatment business field and its excellent
technical background will promise us good future and mutually beneficial relationship." The
shipyard has already signed a letter of intent for two further RWO ballast water treatment
plants with discussions for additional ships in the series at an advanced stage.
The fully IMO type-approved CleanBallast technology has been developed by RWO since
2003, technologically refined over the years and extensively tested in real-life conditions.
Even under extreme situations, such as high sediment concentrations, CleanBallast exceeded the IMO test requirements. The design and the testing of the plant under realistic
environmental conditions is an essential prerequisite in order to guarantee a rapid and safe
intake of ballast water and short times in port. In addition, the efficient removal of the sediments considerably lowers tank cleaning costs and prevents the loss of valuable load capacities.
