A new standard in marine coatings testing

摘要

Do ballast water treatments cause long or short term damage to the coatings applied to the ballast tanks of ships? A new specification created for NACE should arm the industry with the information it needs. John Carter, strategic account director for Exova's General Engineering Division explains further Shipowners, yard operators and insurers are asking what effect treated ballast water could have on coatings and corrosion rates. There is evidence available from testing on the effect of some of the typical chemicals used by ballast water treatment manufacturers, but there is still information missing relating to the systems in practice.
