This paper examines reusable control system technology developed and used on a number of projects, including the Changi Water Reclamation Plant (WRP) in Singapore. Reusable control system components and systems are defined as those that can be reused on other projects. These reusable technologies include control system object models, integrated alarm management, integrated information systems, and data driven integration tools. Each of these technologies will be examined to demonstrate the functional concept and its value.

The driver behind object technology is providing higher client value at a lower cost. The higher client value is derived from an integrated information system that provides the information required to manage operationally complex facilities more efficiently. The reusable technology provides this functionality at a reduced cost.

Operational Benefits

The benefits of using integrated information techniques will be examined as they pertain to the following:

•Providing the data for informed operational decisions

•Reducing ownership cost

•Providing standardization that leads to operational simplicity

Cost-Reduction Benefits

The benefits of using reusable techniques will be examined as they pertain to the following:

•Reduced implementation cost

•Reduced development time

•Standardization

•Reduced startup and debugging time

•Reduced training costs

•Reduced O&M costs

•Reduced support costs on delivered systems

•Reduced maintenance costs
