... In support of Goal I, inspection/maintenance research is needed in the areas of: · determination of performance properties of coatings and other structural presentation techniques; and · determination of corrosion rates for matenais under venous environmental conditions, such as bare steed in the splash zone of seawater ballast tanks filled for 10 continuous days dunug each 40-day voyage. In support of Goal 2, inspection/mainter~ance research is needed in the areas of: · structural monitonug; and blasting and coating application techniques.
