Ballast Water Treatment System Cost Calculator

Estimate ballast water treatment system cost, BWTS retrofit cost, installation CAPEX, annual operating expense and lifecycle cost. Advanced mode can also estimate required treatment capacity, annual treated ballast volume, power cost, chemicals, service, off-hire and cost per cubic meter treated.

Installed Project Cost
Equipment, engineering, yard work, contingency and off-hire
Annual BWTS OPEX
Power, chemicals, consumables, maintenance, sampling and service
Lifecycle Cost
Present value of installation plus operating cost over remaining vessel life

Simple ballast water treatment system cost estimate

Enter BWTS data
Enter ballast water treatment system equipment, installation and operating costs to calculate installed CAPEX, annual OPEX and lifecycle cost.
Planning estimate only. Actual ballast water treatment system cost depends on vessel layout, ballast-pump arrangement, treatment capacity, technology, available electrical power, piping and cable runs, hazardous-area requirements, shipyard location, steel renewal, class approvals, commissioning, crew training, sampling, consumables, maintenance and discovered retrofit work. Validate treatment capacity and operating cost against the selected system, vessel ballast plan and applicable compliance requirements.
