Fouling challenge under low activity

• Generally fouling control products are formulated for consistent

antifouling performance under trading conditions.

• Unlikely be as effective in periods of lower activity and

significant static periods.

• Majority of fouling occurs when vessels are below ~5-6 knots and

significant static periods are a major risk.

• Macro fouling (weed and animal fouling) can result in 25% to

80% increase in drag on the vessel1

EXTREME FOULING ENVIRONMENT

Antifouling schemes• Antifouling schemes are related to vessel speed, activity and the intended in service period i.e.

36 months, 60 months etc.

• Not guaranteed to cover prolonged static periods due to the formation of a leached layer (or

depletion layer) at the surface of the antifouling.

• This is a layer from which the biocide has already released into the sea water. During normal

trading, this leached layer polishes / dissolves off with the movement of the sea water exposing

“fresh” antifouling coating.

• However, when static or slow moving, this layer builds up and effectively seals the active

antifouling and prevents the release of enough biocide to stop fouling.

• Foul release systems will also suffer from fouling under static conditions.

Solutions for lower activity / lay upNo silver bullet…..

• Pro-active - solutions at dry dock:• Faster polishing systems are available that are designed to

perform under static / low activity:

o Deviation from the scheme design (increased speed / activity),

risks early polish through.

o Typically high DFT and can be expensive.

o Requires prior knowledge of expected low activity / static.

o Outfitting antifouling's available for NB.

• For long static periods, accept that cleaning will be required and

specify extra DFT to accommodate cleans (biocidal):

o Practicality of cleaning (location and invasive species).

• Selection of products that have shown good performance under

low activity / static conditions:

o Requires independent performance data.6

Solutions for lower activity / lay upNo silver bullet…..

• Re-active - solutions in service:• Regular inspection and cleaning when required (hull grooming):

o DFT loss via cleaning, potential to reduce scheme life.

o Practicality of cleaning (location and invasive species).

o Damage to foul release systems from contact cleaning methods.

o Damage to hull coatings if fouling left to mature before cleaning.

• For longer static periods, particularly in high fouling challenge locations,

a short period of sailing every 1-2 week(s):

o For both biocidal & foul release.

o Typically 10-12 knots for 4-6 hours.

o Practical?

o No guarantee that fouling will be prevented.

o Product guarantee still likely invalid (activity levels).7

Data from Safinah dry dock supervision projects

Summary

• The market is fragmented with 100’s of fouling control products.

• The data suggests that either the current fouling control products are not

performing as planned or the coatings specified are not suitable for how the

vessel eventually traded.

• The key to making informed decisions on fouling control section:

• Understanding of expected vessel trading conditions.

• Independent data analysis of fouling control product performance.

• Performance expectations.
