Abstract

Traditional weight engineering skills and approaches, such as having in-depth knowledge of ship systems, historical data, and adequate manpower for drawing calculations may not be sufficient to produce quick and accurate weight estimates in today's acquisition reform-minded environment. As demand for technological and business innovation is increasing for upcoming designs, 3D-product modeling is expected to become a standard tool for design, manufacturing, and logistical support. Each CAD system offers certain inherent advantages and disadvantages. Therefore, weight engineers must make up for CAD system deficiencies or customize and expand CAD capabilities. They must have a working knowledge of relational databases and information extractions from design files to produce accurate results faster than the traditional labor-intensive approaches. However, since weight control is a time-based projection, starting from feasibility studies till the end of construction, traditional weight estimating methods must be maintained and integrated with product model data to project the mass properties of the ship, as required. The LPD 17 design has been the test case of the implementation of the Navy's CAD system for preliminary and contract designs. This paper describes our initial experiences in the mass properties area and the lessons learned.
