BALLAST PROJECT GOES FOR ON-BOARD TRIALS

Last week the results of laboratory studies into ballast water treatment techniques were revealed at a meeting of the MARTOB project group. Thermal treatment, de-oxygenation and a hybrid technique involving filtration and UV will now be used for the full scale ship tests.

INTERTANKO participated in a crucial meeting of the MARTOB project group last week in which the results of laboratory studies into ballast water treatment techniques were revealed. Thermal treatment, de-oxygenation and a hybrid technique involving filtration and UV will now be used for the full scale ship tests.

 

The MARTOB ballast water project (MARTOB = On Board Treatment of Ballast Water (Technologies Development and Applications) and Application of Low-sulphur Marine Fuel), funded by the European Commission and directed by the University of Newcastle, has been running for nearly 18 months. The laboratory tests covering treatment of ballast by high temperature (thermal), biological de-oxygenation, ultrasound, ultraviolet, ozone, oxicide and a combination of the aforementioned with filtration were completed in July. Owing to the extensive amount of data received from all these tests it has taken the biologists at Newcastle nearly two months to analyse the results. Although it has been a difficult task with the biological aspects being difficult to illustrate in a clear and statistical manner, the MARTOB group have decided on the three treatment techniques which will be placed on board three trial vessels over the next 10 months.

 

In parallel with the biological testing, INTERTANKO has been involved with the more practical aspects of installing the equipment on board. One crucial factor to consider has been the potential for increased corrosion in the tank and piping system. With input from Environmental Committee members, INTERTANKO has been able to add technical support to the corrosion assessment task. If one of the three solutions proposed for full scale trials fails the corrosion assessment then it will not be deemed viable for testing on board.

 

The project team will be presenting the latest results to the European Commission in Brussels on 21October.
