The US Coast Guard is required to conduct inspections of merchant vessels. The structural phase of these inspections consists of an initial screening of the outside of the hull, decks, superstructure, and internal spaces. This is followed by a close-up visual inspection and conventional nondestructive techniques (NDT) of suspect areas. NDT methods are employed at the vessel owner's expense. Structural inspections of tankships are particularly difficult due to large spaces with limited accessibility. Several projects are underway to investigate alternative technologies to improve the effectiveness of tankship structural inspections. A review has been conducted of other industries to identify those techniques which may be adaptable. The focus is on identifying safe, simple, and practical ship inspection methods and technologies that cover the maximum amount of area in the minimum amount of time while providing a complete and accurate picture of the structural condition of the vessel. This paper presents an overview of the projects associated with improving the structural reliability of merchant vessel tankships. Promising technologies that will be of interest to the shipping industry as well as ways to improve the way US Coast Guard marine inspectors conduct their business are presented.
