Concrete structures located in the marine environment experience many similar types of deterioration that shore structures experience, but the normal mechanisms of deterioration are enhanced and the rate of deterioration is generally accelerated by the presence of oxygen, moisture, and chemicals in the water. In addition, marine structures are subject to external factors such as vessel impact, ice floes, and scour. Mechanisms for concrete deterioration in water include scaling, spalling, cracking, chemical attack and delayed ettringite formation. Comprehensive underwater engineering evaluation programs are essential to ensure the safety of structures located in water, and can reduce long-term costs as part of an asset management plan. Program guidelines should include standard scopes of services; qualifications and technical training for inspectors; inspection frequency in consideration of materials and the local environments; documentation standards; and safety and insurance considerations for work in water.
