Acceptance Standards for Nondestructive Test Not Required by Classification (Phase I)

Abstract

Current nondestructive tests and acceptance standards for radiographic and ultrasonic inspection are generally applicable for full penetration welds in locations within the midship 0.6L such as intersections of butts and seams in the sheer strakes, bilge strakes, deck stringer and keel plates, and butts in and about hatch corners in main decks and in the vicinity of breaks in the superstructure. At times a shipyard other locations, for the a contractual agreement. may perform up to 100% nondestructive examination at purpose of internal quality control or to satisfy Acceptance standards to apply to locations, which are beyond classification society requirements, are not well defined. The objective of Phase I of the project was to determine the quality of welds in existing ships that had proven satisfactory in service and use this information as a basis for developing appropriate guidance for nondestructive testing criteria for locations outside classification requirements. The quality of submerged arc (SAW) deck welds in 18 ships built in the 1943 to 1973 period were evaluated by ultrasonic inspections. Their relationship to an existing ABS Rule and a tentative guideline were determined.
