Operation

Bawat BWTS is operated during voyage with no limitations or disruptions to regular cargo and ballasting operations. Gravity ballasting is still possible. This is a major advantage in itself, but it also allows the possibility of exploiting waste or excess energy, as part of the treatment procedure, resulting in low operational costs. There are additional savings in the fact that the system is comprised of tried-and-true marine components, which means that the system is easily operated and maintained without the need of specialists or training of personnel.



  • Cargo and ballast operation as usual = business as usual
    • Bawat BWTS treats ballast water after cargo operations are completed and does not impact or disrupt activity while the vessel is in port.
    • Facilitates gravity-assisted ballast operations.
    • Time for ballast water treatment depends on vessel's trade pattern, ballast water volume, owner's preferences, etc.

  • Exploits onboard waste energy for lower costs
    • Bawat’s technology requires less power, resulting in lower energy loads to ensure that vessel generators never push their limits.
    • Uses the only BWT technology based on the utilisation of excess heat sources within the treatment process while using very limited electrical power solely to run the system’s circulation pump. 
    • Low overall energy consumption offers a main competitive advantage compared to the competition.
 
  • No chemicals for increased safety
    • Bawat BWTS requires no hazardous materials for handling or storage.
    • The solution is considered a green technology, and to some extent CO2 neutral

  • Cost effective and low operating costs
    • No upgrade of ballast water pumps, pipes or power generators necessary
    • Flexible implementation for almost any type and size engine or pump room
    • Ideal for retrofit applications
    • No consumables.

  • Small foot-print for flexibility
    • With non-skidded components Bawat BWTS is flexible for implementation in almost any type and size of engine or pump room.
    • Ideal for retrofit applications.
    • 3 examples of the estimated total foot print from the bulk and tank segment:
    Bulk Carrier, 25,000 DWT with 10,000 m3 BW capacity: 6 m2
    Oil Tanker, 50,000 DWT with 20,000 m3 BW capacity: 6 m2
    Bulk Carrier, 135,000 DWT with 55,000 m3 BW capacity: 12 m2

  • Use of proven marine components
    • Tried-and-true marine components only, in use for over 50 years.
    • No own production or limited access to system components
    • No 50 µm filters, thus no clogging of filters.
    • No/limited onboard spare part requirements
    • No costly or time-consuming onboard maintenance

  • Corrosion protection of ballast water tanks
    • De-oxygenation of ballast water reduces corrosive process

  • Scalable
    • The Bawat solution is scalable and capable to handle the entire range of    BW capacities independent of ballast pump capacities.
