Recent NAVSEA studies of a twin skeg hull form design applied to a T- AO type ship indicated many areas of possible improvement in producibility. This paper reviews the findings of producibility studies and attempts to indicate specific areas in which an improvement in producibility and attendant cost savings for Navy ships are possible without any degradation in ship performance and survivability. Most available studies on producibility have an inherent trait of elaborating on details of shipyard producibility. This paper attempts to confine itself to the producibility aspect of the design phase, ending with the completion of contract design. While it is necessary for the Navy ship designer to know about producibility details of prospective building yards, he must be careful not to incorporate any details that may be restrictive on some of the prospective builders and thereby hinder competition. Although the application of a twin skeg hull form to the ongoing T-AO program was determined by NAVSEA not to be practicable because of the advanced status of the ship acquisition program, it was determined that the concept of the producible, designed-to-build ship was worth further investigation for incorporation into future designs because of potential cost savings. The paper concludes with recommendations for a method of application of producibility to the Navy ship design process for MSC-operated T-Ships. Producibility is defined as the capability to manufacture, build, or assemble goods in a most cost- efficient manner. For this paper, producibility in the pure sense will have to be subdivided as required for the unique characteristics of naval ship design.
