In seawater, higher strength nickel-copper alloys are used as alternatives to copper alloys. These can be susceptible to chloride stress corrosion cracking and hydrogen embrittlement in conditions where cathodic protection is utilized. Copper-Nickel-Tin alloys (CuNiSn) show low corrosion rates in the free and coupled conditions. Resistance to hydrogen embrittlement is demonstrated.
Performance of formulations of antifouling coatings to protect carbon steel from effects of microbiologically influenced corrosion (MIC) and marine biofouling in a tropical harbor seawater was assessed by field and laboratory experiments. • Scanning electron microscopy (SEM). • Energy dispersive spectroscopy (EDS). • X-ray diffraction (XRD). • Seawater immersion.
Chloromethyl-methylisothiazolone (CMIT/MIT) biocide is used for microbial control in industrial water treatment applications. It is effective versus various types of bacteria, algae and fungi. This paper will provide results of planktonic and biofilm efficacy studies with CMIT/MIT biocide versus various strains of Desulfovibrio.
Biofouling Methods provides a “cook book” for both established workers and those new to the field. The methods included in this important new book range from tried and tested techniques to those at the cutting edge, encompassing the full diversity of this multidisciplinary field.

One of the key factors affecting ship performance, particularly fuel consumption and associated GHG (Green House Gas) emissions, is the degree of biofouling on the immersed hull and propeller(s). Rates of biofouling accumulation vary considerably, depending on the suitability, age and physical condition of the coating system(s) applied to the hull, the voyaging, anchoring and lay up patterns of the ship, and the geographical regions where these take place.
