This paper reviews the benefits of the National Shipbuilding Research Program (NSRP) to the shipbuilding industry, and more specifically, its benefits to the Navy and the shipbuilding and ship repair mobilization base. The paper also identifies significant additional benefits that the Navy can gain in the next few years if the NSRP continues not only on its present course of solving productivity problems in building new ships, but also addresses additional targets of opportunity in solving productivity problems in the overhaul, repair and modernization of Navy ships. The labor part here appears to be an even larger budget item than the labor part of new ship construction.

The authors of this most important paper are to be commended on their excellent presentation of a most important topic. The paper carefully identifies areas where research and development have resulted in improved productivity and reduced costs. The incentives to such development are the greatest when they result in the user gaining a competitive edge. In the case of the shipbuilding industry, the Navy's effort to acquire a 600-ship navy has provided such an incentive. As has been pointed out in the paper, the industry has responded with an impressive number of improvements.

Increases In Risk

This paper examines the environment in which improvements in ship construction can occur and looks at the type of planning that must be done to ensure benefits are realized. The Navy is now the major customer of the U.S. shipbuilding industry, and even with the increased emphasis on competitive procurement, by necessity, contracts for a significant amount of sole-source ship construction will exist due to technical or facility constraints. For these contracts, as well as many others, the shipbuilder has a limited incentive to accept the increases in risk inherent in changing his business strategy and existing industrial processes. Recognizing this problem, the Navy began, successfully, to change the environment for aircraft carrier construction. This paper describes the Navy's efforts.

Do So

Zone construction has been proposed as the way for the U.S. shipbuilding industry to improve its productivity and survive the current hard times. Obviously as the production requirements for zone construction are different from traditional ship construction, so are the engineering requirements. While production could perform zone construction from traditionally prepared engineering, it would do so inefficiently and after waiting a long time for most of the engineering to be completed before they could start, thus defeating one of the goals of zone construction. The production department in a shipyard changing to zone construction will probably reorganize into major zone sections. To obtain maximum benefits from zone construction it is necessary for the engineering department to be like-organized and managed. The paper therefore discusses engineering aspects that are influenced by the change to zone construction

Ultimate Objective

Distortions which occur during the assembly of steel panel structures can be removed by flame straightening—a technique that has been used for a number of years in the shipbuilding industry. Correct skill to perform this technique is acquired by many years of experience. The industry is concerned now about the decreasing number of skilled workers. What is needed to improve the situation is to develop a robot capable of not necessarily replacing a human worker, but helping a human worker. This paper discusses results obtained thus far in a research program of which the ultimate objective is to develop an intelligent machine capable of performing flame straightening on a deck of a ship superstructure. Discussions are given on (a) a concept of an algorithm to determine heating conditions, and (£>) sensors needed for "in-process" sensing and controlling the robot movements.

Initial Results

In the mid-eighties, the state-owned shipbuilders of Spain were suffering from many typical shipyard problems, making them uncompetitive. After making a strong reentry in the commercial shipbuilding market, they engaged in a process of reorganization of the entire production system according to modern Japanese practice. The goal was to become competitive with the world's best. The know-how was acquired via cooperative agreements with leading Japanese shipbuilders as well as through the use of American consultants and National Shipbuilding Research Program (NSRP) related literature. A comprehensive technological improvement plan has been launched and the initial results are very promising.

Repair Techniques

Repair by welding is widely used in the shipbuilding industry during ship construction. The effect of the residual stress distribution induced by the welding process on the ship structure is important for the repair effectiveness. This article presents an experimental study of the residual stress distribution induced by repair welding in the plates that are typically used in ships and offshore structures. Different repair techniques are evaluated to identify the best practice associated with residual stress values. Recommendations for repair welding are discussed, and modifications to the present practice are proposed.

Production Techniques

Despite the obvious compromises to efficiency that must be made when producing small quantities, the shipbuilding industry sometimes rules out or fails to consider some of the efficient techniques and methodologies of mass production manufacturing. In this paper a comparison and contrast is made between the methods of mass production and small quantity manufacturing. Also revealed in this paper are the benefits from the use of a mass production process engineering technique and a methods analysis technique during the performance of the National Shipbuilding Research Program SP-8 Panel Task ES-8-21. The use of a mass production process engineering technique is explained as a solution to a methods problem of excessive travel for tools in shipyard equipment installation by outside machinists. The paper concludes with a promotion of this specific application of mass production methodology in shipbuilding and a promotion of the re-evaluation of mass production techniques by shipyards as a vehicle for productivity improvement.

Large manufacturing industries have been able to successfully reduce cost and cycle time through the use of Manufacturing Resource Planning (MRP II) systems and principles to control material flow and the production process. Ship construction cannot be neatly classified as a manufacturing process. The complex relationships involved with the installation and activation of ship's systems more closely resembles a construction operation. Work of this type has traditionally been controlled through an activity based network scheduling system. However, MRP II principles offer numerous benefits for the shipbuilding industry. This paper discusses an approach to planning, scheduling, and management of ship construction which takes advantage of benefits from both approaches. By using both network scheduling and MRP II in an integrated scheduling system, a shipyard will be better able to plan and execute the ship construction process.

The National Shipbuilding Research Program (NSRP) Advanced Shipbuilding Enterprise (ASE) began formally in 1998, with a mission to manage and focus national shipbuilding research and development funding on technologies that will reduce the cost of warships to the US Navy and will establish international shipbuilding competitiveness. A key means for accomplishing this mission was to provide a collaborative forum for improving business, shipbuilding, and ship repair processes. In response to a Navy request, shipyard executives formed Articles of Collaboration, which enabled the execution of a Joint Funding Agreement (JFA) with Naval Sea Systems Command (NAVSEA). Successes from the Defense Advanced Research Projects Agency (DARPA) Maritime Technology (MARITECH) program and the National Shipbuilding Research Program (NSRP) were leveraged to initiate a framework that would enable collaboration and sharing. Leaders of the Ship Production Committee (SPC) panels of the Society of Naval Architects and Marine Engineers (SNAME) also joined the collaborative forum, and the NSRP ASE was formed. Through the new collaborative forum, the strategic investment plan (SIP) was created, outlining consensus priorities in six major initiative (MI) areas and setting a course toward more affordable ships.
