Owners and operators of equipment made from Fiber Reinforced Polymer (FRP) have similar needs to know the Fitness For Service status of this equipment as they do for equipment made from metal alloys. Historically, inspection of this equipment has evaluated the appearance compared to the requirements of construction codes and standards. These methods usually do not provide results that can be used in an engineering analysis that can be verified against Fitness For Service criteria. This paper will provide descriptions of damage that occurs to polymeric structures from service conditions - both chemical and stresses. The damage will be expressed in engineering terms, followed by a brief discussion of how the damage is used in engineering analysis to determine the current status of the equipment, remaining life and the urgency of any repairs or remediation. Some comparison to historical inspection will be provided. The paper will then discuss inspection methods that can provide the damage data in forms that can be used for engineering assessment of the equipment.
