摘要: | The objective of this manual is to develop a set of equipment and distributive system installation standards that result in the lowest possible installed cost. These standards are to be parametric in nature and lend themselves to inclusion into a product modeling system. Traditionally the design of foundations and hangering systems was based on qualitative requirements that have been developed from what is known as the principles of good sound shipbuilding practices. Line organizations in most shipyards have been conditioned over the years to properly implement the specifications. The basis or rationale for much of the specifications has been lost over time. It is difficult to attempt to initiate changes in design to reduce costs when engineers and designers will not risk departing from traditional ways because they are fearful of violating unknown criteria. Guidance on designs provided by engineering management organizations usually instructs the designer/engineer to use designs developed on prior ships as a basis for new designs. In this way previous designs are perpetuated and little or no innovation is permitted in the development of new designs. The present technology for designing manufacturing and installing equipment foundations and systems is labor intensive and is often on the critical path of ship construction. The lowest total installed costs will be achieved through the streamlining or elimination of these labor-intensive tasks. Leapfrog Technology is defined within this project as a holistic cost effective approach to combining and applying innovative yet simple products and processes concurrently throughout various departments including engineering fabrication shops and production stages of construction. By applying leapfrog technology products and processes concurrently throughout all departments within the shipyard significant reduction of man-hours and construction lead times can be achieved in the area of foundations and hangering systems. |
