The Ultrasound Antifouling Technology “Dynamic Biofilm Protection Intelligent®” prevents marine growth and biofouling on all liquid carrying surfaces. Systems and coatings which release biocides and/or heavy metals into the oceans are not contemporary anymore and can be fully replaced in an environmentally friendly and sustainable way.
This improves the environment rating of the vessel, reduces the maintenance on board, increases operational and reduces operational expenses. As DBPI® at the same time prevents biocorrosion the lifetime of the protected applications on board will be extended.
Biofilm forms by the random settling of microorganisms on surfaces that convey liquids. These multiply and form a kind of protective film, which ensures even better adhesion and at the same time increases resistance to external influences. Further germs establish themselves and promote the growth of the film, which now also begins to spread. By absorbing nutrients (e.g. metals), the gel film can also harden, which further increases its mechanical resistance. Biofilm is the initial base for marine growth and biofouling.
Dynamic Biofilm Protection intelligent®
DBPi® is the next generation of Dynamic Biofilm Protection® of HASYTEC, the German ultrasound technology which has won multiple international awards. DBPi® prevents marine growth, biofouling and biocorrosion on all liquid carrying surfaces even more efficiently and at the same time follows the current and future demands of the shipping industry. Systems and coatings which release biocides and/or heavy metals like copper into the oceans are not contemporary anymore and can be fully replaced in an environmentally safe and friendly way, being sustainable at the same time. This improves the environment rating of the vessel, reduces the maintenance on board, increases operational safety and reduces OPEX. As DB Pi® at the same time prevents biocorrosion, the lifetime of the protected applications on board will be extended.
The combination of artificial intelligence and non-cavitational ultrasound antifouling, used for the first time, enables all affecting environmental parameters to be taken into account.

Propeller | Pod Drives
DBPI® prevents reliable and continuously marine growth and biofouling on all propulsion propellers. The use leads to constant propulsion parameters and provides a positive impact on propeller’s smooth running. According to general opinion, bio fouled propellers, leading to 1 – 3.5% increase in fuel consumption. The use of DBPI® safes this increase in fuel and at the same time safes the cost for underwater propeller cleanings. Available for shaft propellers as well as for pod drives.
Seawater Cooling System
DBPI® prevents marine growth and biofouling on seawater cooling systems. Sea chests, filter housings, strainers, crossover pipes, distributions pipes, plate heat exchangers (high temperature and low temperature) as well as box coolers (high temperature and low temperature) can be protected according to single issues or as a whole system in a reliable and continuously way against marine growth and biofouling. The previous used systems which are mainly based on the working principle of copper anodes can be fully replaced by DBPI®.
DBPI® prevents marine growth and biofouling on all available types. At the same time salt and limestone deposits are prevented. Acid or even physical cleaning is not required any longer. This increases continuously and reliable the operational safety of the freshwater generator. On plate type based freshwater generators the use of DBPI® reduces on top of that the spare part costs for damaged sealings or plates due to frequently required cleanings.
Bow Thruster | Stern Thruster
DBPI® prevents reliable and continuously marine growth and biofouling on bow thrusters and stern thrusters. Herewith the operational safety is increased.
