Smar t III John Smar t Consulting Engineer E arlier this year, I was designated a "NACE Maritime Champion" by NACE International's Chief Maritime Officer Buddy Reams. A NACE Maritime Champion is someone who helps to promote awareness and implementation of NACE's strateg y of leveraging its extensive corrosion exper- tise and experience within the maritime industry, and we can be recognized by our lapel pin. The term "maritime" has multiple defi- nitions connected with the sea: commer- cial or military seafaring, living or operat- ing in or near the sea, using the sea, etc. NACE views the maritime industry as encompassing any asset (fixed or move- able) that touches a body of water. This includes commercial, military, and recre- ational ships and boats; shipyards; fixed and f loating navigational aids; offshore wind farms and other subsea energ y proj- ects; subsea pipelines; port infrastructure; and moveable bridges over waterways. Many define the environment around a body of water as a marine environment. Various dictionaries describe the marine environment as comprising oceans, seas, bays, estuaries, other major water bodies, and the air around them. Other sources define it as waters that are saline and affected by tides. The key word here is saline—saline water contains a significant concentration of dissolved salts and is very corrosive to assets. NACE reports that the estimated total cost of marine corrosion worldwide is between US$50 billion to US$80 billion every year. Research on corrosion in marine envi- ronments continues as many industries look for solutions for preventing asset deg- radation. In the Material Matters article on p. 17, results are reported on a study to determine if thermal-sprayed aluminum (TSA) coatings can protect subsea pipe- lines at the high pressures found in deep water. TSA, which is applied as both a pro- tective and sacrificial coating, can be damaged by rocks and other debris hitting pipelines and other structures resting on the sea f loor. A trial galvanic cathodic protection (CP) system developed for the internal walls of offshore wind turbine monopiles in two North Sea windfarms is discussed in the feature article on p. 28. The interiors of these submerged support structures were considered to be sealed environ- ments and not susceptible to corrosion, so corrosion protection systems (i.e., coatings and/or CP) were not used. When corrosion was discovered, a CP retrofit project uti- lized galvanic anode strings inside the monopiles for corrosion protection. While industry generally takes a proac- tive approach to managing corrosion, sometimes corrosion strikes in unex- pected ways. When corrosion led to a gas cylinder explosion on the Emerald Princess cruise vessel in New Zealand, the country's Transport Accident Investigation Com- mission (TAIC) raised questions as to whether current inspection requirements are adequate. A recap of the TAIC's investi- gative report can be found in the Material Matters article on p. 14. The maritime industry will certainly benefit from NACE's commitment to addressing corrosion challenges in marine environments. In addition to recruiting a corps of Maritime Champions, NACE has achieved observer status with the United Nations' International Maritime Organiza- tion and will support that organization's work with corrosion science and engineer- ing expertise. NACE is also sponsoring a Performance Standard for Protective Coatings (PSPC) review among ship own- ers, ship builders, classification societies, and coating inspectors to encourage cor- rosion-related technical discussions between NACE experts and industry stakeholders.
