Materials Trends in Marine Construction
Abstract
The use of materials in high performance structural systems, such as, offshore platforms or habitats, surface ships and submersibles has emphasized the need for engineered materials. The use of metallic materials has the advantage of a large data base on the processing fabrication effects on structural integrity. There is still the need to approach the overall design problem using a synergistic method to account for the interaction of the environment with thermal mechanical processing and weld fabrication aspects. Although not discussed, the need for detailed maintenance and nondestructive evaluation inspection programs can not be under emphasized in order to insure structural integrity. While reinforced and prestressed concrete have been utilized successfully, polymer matrix composites require more realistic specifications for efficient weight and cost large structures. Joining methods for PMC materials must also be examined in much more detail. Keywords: Marine grade steels; Welding; Carbon equivalent; Graville diagram; Weld defects; Weld joints; Titanium alloys; Polymer matrix composites; Marine applications of composites; Marine concrete structures; Engineered materials.
