Testa & Cunhas clean up fishing vessels tanks and engines with XBEE enzymes

The Testa & Cunhas company’s mission is to provide consumers with a natural product of their choice, safe and nutritionally incomparable, respecting the principles of sustainable exploration of the oceans.

It operates a fleet of 14 trawlers, which operate from Portugal’s main fishing ports: Matosinhos, Aveiro, Peniche, Sesimbra, Setùbal, Portimăo. This fishery carried out tests with XBEE to clean diesel oil tanks on its vessels.

After an initial two-year trial – 2007 and 2008 – onboard two vessels, Testa and Cunhas have decided to extend the application of the XBEE enzyme additive. This time, onboard four more units, as the trial proved to be fully satisfactory.

The XBEE biotechnology has allowed the cleaning of diesel tanks, including solving impurity problems in a period of six months, as well as substantially improving the cleanliness of the engines.

In addition, the company confirms the following points:

  • Decrease in engine operating temperature.
  • Reduction of engine oil consumption: from 15 to 30% depending on the type of engine.
  • Decrease in diesel filter consumption.
  • Reduction in fuel consumption.
