Professional shipping

We are continuously testing and improving our systems with the help of known partners in the shipping industry.

CIP Applications in the maritime sector include:

  • Protection against bio-fouling of heat exchangers:
    • box coolers
    • tube coolers
    • plate coolers
  • Treatment of sanitary water systems (tanks, pipes, calorifiers)
  • Protection of marine structures against:algae

Year after year the environmental regulations on anti-fouling paints are becoming stricter!

See for example: IMO regulations on anti-fouling

  • Water treatment in pipes, tanks and filters:
  • against lime scaling (calcium carbonate)
    • for reduction of bacteria growth (for example legionella pneumophilia, E. Colli,..)
    • against slime formation and algae
  • Desalination plants:
    • against the formation of a biofilm in the membranes of a reverse osmosis or ultrafiltration system.
  • Tests are ongoing for to help with the treatment of Ballast Water of worldwide seagoing vessels:
    • As per BWM Regulation D-2 (8 sept 2017, now postponed)
    • Limitation of indicator microbes:
      • Toxicogenic Vibrio cholerae (O1 and O139) with less than 1 colony forming unit (cfu) per 100 milliliters or less than 1 cfu per 1 gram (wet weight) zooplankton samples
      • Escherichia coli less than 250 cfu per 100 milliliters;
      • Intestinal Enterococci less than 100 cfu per 100 milliliters.

In general , the ultrasound technology is used to reduce DBPs (disinfection by-products) that are pollutants and are ozon depleting (like bromoform).

The USCG has similar rules in place.

  • Fuel tank and filter treatment against the diesel bacteria. (avoiding slime/sludge formation and clogging)

Some negative effects of bio-fouling include:

  • heat transfer loss (increasing the energy cost)
  • health issues (such as pathogenic bacteria growth)
  • downtime due to equipment failure (increase of operational costs)
  • increase of maintenance cost (labor and material)
  • decrease of equipment MTBF
  • the need to use (mostly aggressive) chemicals
  • increase of fuel consumption due to hull fouling
  • expensive emergency drydocking’s
