This paper describes the diverse corrosion mechanisms observed in tank inspections and illustrates these mechanisms by failures observed in a survey of Aboveground Storage Tanks (AST). It concludes, the majority of tank failures, decommissions and environmental threats could have been prevented by rigorous initial design, proper construction, routine housekeeping and regular inspection, together with, conscientious assessment of data and subsequent monitoring.

Cathodic protection is a proven technology for controlling corrosion on the bottoms of above ground storage tanks. This paper addresses various options for cathodic protection of the external (groundside) surfaces of tank bottoms which are in contact with sand pads or native soil. Advanced application techniques are described for both existing tanks and new construction with secondary containment. BACKGROUND

HDD crossings are now being undertaken in most soil and rock types with crossings up to 2000m in length and pipe diameters up to 48 ". Whilst HDD crossings have a predictable and short construction schedule and in most cases are the least expensive crossing method, proper planning and design are of primary importance to the success of the crossing. The design requirements and considerations for a successful HDD crossing are examined and put into perspective based on the economics involved. Secondary factors such as selection of plant-applied and field-applied external protective coatings also play an important role. Common types of plant-applied anti-abrasion coatings used to protect the anti-corrosion coating and results from the various test methods used to relatively rank these coatings are discussed.
