Marine structures are subjected to varying degrees of accelerated weathering. Not only are they immersed in the saline solutions of the sea but in addition they are subjected to severe mechanical abuse which aids the searching sea water attack in uncovering every defect of design and construction. The impinging blows of waves, the repeated wetting and drying of spray, the alternating exposure and covering of surfaces by the tide, the impact of drift impelled by current, the cutting effect of sand, the racking blows of heavy ships-all this mechanical wear and tear aching in conjunction with strong electrolytes of the sea produces a condition where erosion and deterioration is the natural order of things. In fact the destructive effect of the mechanical abuse and the mechanical application of the sea water is so variable that the chemical effect of sea water exposure is largely obscured. The failure to recognize this wide variation in exposure has resulted in confusion in the study of the subject, and to seeming contradictions in the discussion of it.
