How does TeamTec’s BWMS achieve the lowest power consumption in the market?
The Senza BWMS, is designed for minimal energy use through several key innovations.
Unlike electrochlorination systems that generate disinfectant onboard (which requires significant power), Senza BWMS uses externally supplied non-proprietary sodium hypochlorite, eliminating the need for energy-intensive and complex electrolysis. UV-based and filtration systems require continuous power for lamps and pumps, whereas Senza BWMS avoids these energy-heavy components. Since the system does not rely on high-pressure filtration or intensive pumping, it reduces strain on ballast pumps and lowers vessel fuel consumption. The system only requires energy for temperature-controlled storing of the biocide, dosing and monitoring, making it one of the most power-efficient BWMS solutions available.
What are the long-term cost benefits of using a low-energy BWMS?
By reducing electrical demand, it indirectly lowers the vessel’s overall fuel usage and cost. With no onboard electrolysis cells, UV lamps, or high-maintenance filters, operating costs and servicing requirements are minimized. The absence of complex power-hungry components means fewer replacements and lower spare parts expenses. Some BWMS require auxiliary power systems to handle their energy demand. Senza BWMS avoids this cost by running on minimal power.
Lower energy usage also contributes to a vessel’s EEXI (Energy Efficiency Existing Ship Index) and CII (Carbon Intensity Indicator) compliance.
How do different water conditions impact energy efficiency in ballast water treatment?
Since Senza BWMS uses pre-supplied non-proprietary sodium hypochlorite, its power consumption remains largely independent of water conditions. However, some factors can influence dosing needs and, indirectly, energy efficiency. More organic matter requires a higher dose of sodium hypochlorite, but the energy demand for dosing remains low compared to filtration-based or UV/electrochlorination systems. Unlike onboard electrochlorination systems, which consume more power in low-salinity or freshwater, Senza BWMS is unaffected, since it relies on externally supplied disinfectant.
UV-based BWMS require more power in turbid waters due to increased lamp intensity. Senza BWMS does not rely on UV, making its energy use stable across varying conditions and flow.
How does an energy-efficient BWMS contribute to meeting IMO and USCG compliance requirements?
Unlike UV-based and filtration systems that face challenges in turbid, fresh, or low-salinity water, Senza BWMS provides stable compliance performance without affecting the operations of the vessel.
What should shipowners look for when evaluating the energy efficiency of a BWMS?
Comparing kWh/m³ helps quantify energy efficiency across different systems. Look for the maximum power consumption or the power consumption in CWQ waters. A system with low pressure loss reduces overall energy consumption as well.
Energy-efficient systems should require minimal operator intervention and integrate smoothly with existing vessel power infrastructure. A BWMS should effectively meet IMO and USCG standards without exceeding vessel power limitations.
