Vessel Biosafety Program (VPB )

Clearvac Italia, has developed a control system to assist Vessel’s crews to have a knowledge of the possible biohazard in their air conditioning and water systems with regard to Legionella, viruses, bacteria and mold. The procedure includes an on-board investigation where all possible risks of the various systems are highlighted and recorded. At the end of the investigation, Clearvac releases a detailed report with the initial lab  results, best practices of self-control and possible solutions to reduce or manage the risk of contamination.


Actual demand in the industry requires stricter guidelines to assist the crew, guests, management companies and insurance companies to have greater control over air and water quality on board a vessel.

What we can do:

Clearvac, following the inspection, compiles a check list in which all air conditioning systems, fresh water systems will be detailed and develops a risk assessment, takes air and water samples and sends them to the laboratories, depending on the results of the analysis is also able to provide remediation work through our products, services and collaborations.

An exhaustive report will contain:

– Biological risk assessments of the plants.

– Initial laboratory tests

– Suggested remediation works

– New product/system suggestions to implement both air and water quality and reduce contamination risks.
