Legionella Prevention on Board Ships, Yachts & Offshore Installations
Ensuring safe drinking water on board is essential for maritime operations. Poor water hygiene can lead to the growth of Legionella bacteria, posing serious health risks to crew and passengers and potentially leading to non-compliance with international maritime drinking water regulations.
A proactive and continuous legionella prevention strategy is therefore critical for vessels and offshore installations.
What Is Legionella and Why Is It a Risk On Board?
Legionella is a waterborne bacterium that develops in:
- Stagnant water tanks
- Complex pipe systems
- Warm or fluctuating water temperatures
When inhaled through contaminated water aerosols (e.g. showers or taps), it can cause Legionnaires’ disease, a severe form of pneumonia.
Why Maritime Water Systems Are High Risk
- Long pipe runs and dead legs
- Periods of low or intermittent water use
- Limited access for frequent manual treatment
- High regulatory and inspection pressure
Without continuous treatment, even modern water systems can become a breeding ground for harmful bacteria.
The Importance of Continuous Legionella Prevention
A controlled dosing prevents:
- Biofilm formation
- Bacterial regrowth
- Sudden contamination peaks
This approach supports:
- Compliance with drinking water norms
- Crew and passenger health
- Operational reliability and reduced maintenance
