Equipment location drawings

Describe process legends and foundation, elevation, electrical, and equipment location drawings.

Equipment location drawings show the exact floor plan location of equipment in relationship to the plant s physical boundaries. Figure 7-23 illustrates this layout. Location drawings provide benefits similar to those of elevation drawings. The entire P ID provides a three-dimensional look at the unit. 

Potential accident scenarios and flood locations were identified from plant drawings and tlic RHR system fault tree that identifies the equipment and support needed for RHR system operation. The equipment location was correlated with flood areas with consideration for plant features which may impede or divert the flow. The flood scenarios identify the effect on systems required to prevent core damage. Quantification accounts for the rate of rise of the flood relative to the critical level in each specific plant area. The time available for any recovery action is calculated from tiic volume and the flow rate.

System P IDs, specifications, and equipment locations or layout drawings that are sufficiently developed to show equipment locations and dimensions, nozzle locations, and pressure ratings are needed to develop the piping layout. A completely dimensioned pipe routing from one point of connection to another with all appurtenances and branches as shown on the P ID should be prepared.

At the end of the concept-definition phase, layout drawings that describe the platform in sufficient detail are made available. The EPC contractor performs Coarse analyses of all areas of the platform, i.e. process, utility, drilling and the living quarters. They invite Norskoil s operations personnel to participate in the analyses. The analysis teams concentrate on expected problem areas related to layout, such as manual materials handling, work in open areas, access to equipment, location of noisy equipment, and solitary work. A number of layout changes are introduced as a result of this evaluation. 

Client s Inspector will check, as a minimum, equipment components, dimensions, connection sizes and locations, and quality of workmanship against certified drawings, data sheets, and purchase order documents. 

The FMECA table should be concise, complete, and well organized. This table should identify equipment and relate it to a system drawing or location. This is to prevent confusion when similar equipment is used in different locations. One of tlie limitations of FMECA is tliat the table must include ALL failure modes for each piece of equipment and effects of each failure along witli tlie associated criticality ranking. Table 17.5.3 shows a sample chart tliat can be completed for tlie FMECA table. 

Faucets chosen by the engineering firm were equipped with antisiphoning devices. The laboratory operator had specified their locations but had failed to check whether the local code required the expensive anti-siphoning type. The bench-mounted outlets installed for use with condensers and similar devices, however, were not of the anti-siphoning type, even though in this particular laboratory, the latter would be far more likely to draw water back into the system in case of pressure failure. 

Aseptic BPS machines are subject to steam-in-place sterilization following standard CIP cycles. The SIP cycles are routinely measured by thermocouples located in fixed positions along the product pathway. Validation of SIP cycles should be carried out to demonstrate that consistent sterilization temperatures are achieved throughout the equipment to prove that the system can be effectively sterilized. Validation should also identify suitable positions for routine use, or justify the fixed probe positions already in place. The SIP validation is generally carried out with the help of additional thermocouples and should include the use of biological indicators (appropriate for moist heat sterilization). Test locations should include areas which may be prone to air or condensate entrapment. An accurate engineering line drawing of the system to aid identification of suitable test locations and document test locations selected should be available. 

Where process equipment is provided with fixed-temperature detectors, these should be located as near as possible to the potential fire source for example, above flammable liquid pump seals, immediately over a solvent draw-off point, or mounted above a crude tank mixer stuffing box. As a general rule, fixed-temperature detectors directed at a potential hazard should be considered only for process equipment where specific fire problems are anticipated.

Initial Sketch. Figure 2 shows a process flow diagram for a petrochemical plant (1,2). This drawing shows the feed and products so the designer knows what to allow for these lines in the interunit pipeway routing. The process engineer has indicated with notes which pieces of equipment will be located in elevated structures, such as the overhead condensers, and has also shown which equipment should be located close by other equipment, such as the reboiler next to its column. Primary instrumentation is shown to indicate that room is required for instrument drops to these control valves. All this...
