bwms@teamtec.no
Efficient ballast water management system for small vessels. Filter-free design with low energy use and reduced OPEX. The TeamTec Senza BWMS series now offers capacities ranging from 50 to 3,750 m³/h.
Key improvements
Simplified & smaller system with fewer components
Integrated into a single skid for easy installation
Reduced biocide tank size, lowering costs
Easier operation, training, and maintenance
The system operates without filters, eliminating the need for backflushing and reducing maintenance requirements. This ensures simpler operation and improved reliability over time.
Lower maintenance – No filters to clean, replace, or backflush, reducing crew workload and downtime.
Reliable operation in challenging water conditions – Handles high turbidity, sediment, mud, algae, and ice-prone waters without clogging.
Reduced operational complexity – Fewer moving parts and components mean simpler operation and improved reliability.
Lower pressure loss – No inline filter reduces flow resistance and energy consumption.
Compact footprint – Requires less installation space and piping compared to filter-based systems.
Improved uptime – Eliminates common filter-related failures and shutdowns during ballasting operations.
Cost-efficient lifecycle – Lower spare part usage and reduced maintenance costs over time.
Suitable for harsh marine environments – Particularly beneficial for vessels operating in ports with poor water quality or heavy biological load.
The TeamTec Senza Compact BWMS is designed for exceptionally low energy use, making it one of the most power-efficient BWMS solutions available. This reduces onboard energy demand and lowers overall operating costs.
Reduced operating costs – Lower energy use means lower fuel or electricity consumption.
Lower emissions – Helps reduce CO₂ footprint and supports environmental compliance.
Less load on onboard power systems – Frees up electrical capacity for other critical equipment.
Improved energy efficiency – Particularly valuable for vessels operating continuously or with limited power availability.
Lower heat generation – Reduces cooling demand and wear on electrical components.
Supports sustainable vessel operations – Contributes to greener and more future-proof ship design.
Ideal for retrofit projects – Easier integration on vessels with limited available power.
With its compact design and minimal system complexity, the TeamTec Senza Compact BWMS offers a small, configurable footprint that requires minimal changes to existing ballast piping. This enables easy integration in both newbuild and retrofit projects, reduces installation time, and even allows for installation during operation.
The TeamTec Senza BWMS uses a well-established direct biocide injection method to ensure effective and compliant ballast water treatment. Sodium hypochlorite is applied during ballasting, while sodium sulfite is used for neutralization during discharge. The use of standard, non-proprietary chemicals ensures reliable, predictable operation and global availability.

TeamTec holds a professional staff of service engineers ready to assist our customers worldwide.
Follow our guidelines for safe operations
TeamTec service engineers ensure that the new equipment is correctly installed; they also test all functions, alarms and safety devices to ensure reliable and safe operation.
By using one of our highly skilled service engineers, you ensure that the downtime of your equipment is reduced to a minimum.
The purpose of such a ship visit is to plan the installation or replacement of a ballast water management system, including space considerations.
Ensure that your BWMS remains in good working condition and properly maintained by annual service visits from our crew. A service agreement will include required training and updating of the crew who operates the BWMS onboard.
Having the BWMS in good working condition will simplify acceptance by local port authorities and help avoid claims.
TeamTec’s highly qualified and experienced engineers provide comprehensive training worldwide. The focus of the training is to give the operator and supervisory staff the theoretical and practical knowledge they need to operate and maintain your BWMS in the right way.
Chemicals used for Senza BWMS are standard type and available world wide!
Ballasting: Biocide (Sodium hypochlorite) – CAS# 7681-52-9
De-Ballasting: Netralizer (Sodium sulfite anhydrous) – CAS# 7757-83-7
No. You can buy them from any supplier around the world, as long as they guarantee that they can deliver according to the product datasheet.
This makes it very easy for all customers to negotiate their own best price with the supplier.
"Holding time" for brackish and sea water: 4 hrs.
"Holding time" for fresh water: 8 hrs.
No, Senza injects biocide (Sodium Hypochlorite) at 16 ppm. This concentration treats all kind of water and is in compliance with all demands.
As Senza is a filter-free system, there is no reduction in flow rate related to type of water.
Maximum 0,15 b because of the mixing unit.
Yes, Senza components can be installed at any available space!
The injection pump skid should be installed at the same level as the biocide tank or below, to secure a smooth feeding process.
Unlike electrochlorination systems that generate disinfectant onboard (which requires significant power), Senza BWMS uses externally supplied 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.
