Design documentation

This section provides a detailed example of flare system specification. This is an example of a formal design document that would be provided by the plant designer to a flare system vendor. The reader should consider this section as an example of the types of information and level of detail needed in specifying the system, however the format and organization might certainly be changed to suit the particular needs of the plant operations. 

GO is suited for many PSA applications with boundary conditions well-defined by. i system schematic and other design documents to quantify the components. 

It is necessary to verify that all the documentation needed to produce and install the product is compatible that you haven t a situation where the design documentation requires one thing and the production documents require another or that details in the... 

As design documents are often produced at various stages in the design process they should be reviewed against the input requirements to verify that no requirements have been overlooked and that the requirements have been satisfied. 

Identify the principal requirements, specifications, drawings, or other design documents that are affected by the change. 

Within the design documentation you will need to provide for the attachment of modification plates on which to denote the modification status of the product. 

Decide on the conventions to be used in identifying the issue status of design documents during development and following design certification. 

Decide on the criteria for judging when design changes should be incorporated into design documentation. 

Do record the design documentation status used in the performance of calculations and analyses. 

The standard requires the supplier to comply/ with all customer requirements for designation, documentation, and control of special characteristics and to supply documentation showing compliance with these requirements. 

In applications where the liquid is used directly by one or more system components, the contribution of these components to the total system head may be difficult to calculate. In some cases, the vendor s manual or the original design documentation will provide this information. If these data are not available, then the friction losses and back pressure need to be measured or an over-capacity pump selected for service based on a conservative estimate. 

All stages of antibiotic manufacture from fermentation through to finished product are governed by the code of good manufacturing practice (GMP), of whieh quality eontrol is one aspect. GMP requires that there should be a eomprehensive system, so designed, documented, implemented and controlled, and so furnished with personnel, equipment and other resourees as to provide assuranee that products will consistently be of a quality appropriate to their intended use. ... 

Safety Requirements Specification The instrumentation and electrical (I E) requirements are developed to meet the intent of any H RA findings and the process requirements. The design documentation should establish a clear connection between each process hazard and the design of its SIFs. I E personnel should meet with the process engineering representative responsible for the process requirements to ensure that the intent is understood. 

Type The designer should know what types of object can be held in a variable—that is, the expected behavior of the object to which it refers. In Self and bare Smalltalk, this is left to the design documentation in C++, Java, and Eiffel, it is exphcit and some aspects are checked by the compiler. Explicit typing is allowed in some research variants of Smalltalk because it makes it possible to compile more-efficient code other compilers try to deduce types by analyzing the code. 

A design document should also explain how the design realizes the specification—that is, how the individual type models of the designed components together realize the specified type model—and how sequences of interactions in the design realize the required external behavior. The details are covered in Chapter 6, Abstraction, Refinement, and Testing. 

Consciously tradeoff performance, reuse, and flexibility optimization against entirely seamless design document a refinement clearly whenever you must stray significantly from a pristine domain model. 

What will happen to the other design documents The design material usually represents more valuable work than the code itself, so you can build a prototype as a throw-... 

In short, if given a complete implemented system—source, design documents, development structure of the project, and running installation—how would you determine whether it conformed to this architectural drawing ...

Company). The product of the FEL process is a design-basis package of customized information used to support the production of detailed engineering design documents. Completion of the FEL design-basis package typically coincides with project AFE (Authorization for Expenditure) or project authorization. Project authorization is that point in the project life cycle where the owner organization commits the majority of the project s capital investment and contracts.
