Equipment floor models

As a preliiniiuiry step to the layout of process equipment, storage facilities, and materials-handling equipment, scale models of the pertinent items were constructed and manipulated until a rational arrangement appeared. It was desired to effect efficient coordination of the units with due regard for economic distribution of water, steam, and power, economic use of floor space, and elimination of predictable hazards. Figure 5-7 depicts the over-all layout of the proposed plant area as finally modified. From it the complete equipment layouts and elevations in the process building should be sketched. 

Another possibility is to ask for a floor model of a particular high-priced piece of equipment. The floor models are often used for demonstration purposes or at conferences. Because they have been slightly used, a vendor can often sell such equipment to the safety and loss prevention professional at a reduced cost. However, you have to ask. 

Suga (40) makes two light stability xenon testers, which are shown in Figure 29. One (A), the XT2-15 is their tabletop unit called the Table Sun model whereas (B), X25 is a stand-alone, floor unit. The Table Sun has a proprietary 1500 W, long-arc, xenon lamp of a unique physical design, as illustrated in (C). The units come equipped with a turntable to rotate samples and help equalize exposure.

All process units and some of the off-plot plants were modeled on the design floor. The models were to scale (3/8" to l -O or 1 33) made out of plastic and showed in detail all equipment, piping, structural steel, instrumentation and most of the electrical items. 

Field measurements were performed in a model room (office) with a surface of 17.3 m and a height of 3.7 m (V = 64 m ). The air exchange rate is = 0.3 Ih" (door and windows closed). The floor is covered with textile carpet and the walls are of gypsum board coated with water-based paint. The room is equipped with desk, chair, bookcase and wooden shelf board. 

The cost of labor, capital equipment and floor area were estimated for each step in the process for the baseline plant. The cost model accoimts for different scales of manufacture and different battery designs by recalculating the costs of each manufacturing step. The general approach to cost estimation of multiplying a known cost by the ratio of processing rates raised to a power has also been applied to the capital cost of individual items of equipment [25], Eqn (6.6). 

The modelling of equipment is typically divided into several categories, as shown in Fig. 3. For components not modelled together with the supporting structure, the input for analysis is the floor response, expressed in terms of either design floor time histories or design response spectra. ... 

Plastics made a brief but successful entry into the area of control pedals in the early 1960s, when several General Motors models were equipped with floor-mounted accelerator pedals in polypropylene mouldings incorporating an integral hinge. These represented a two-thirds cost reduction compared with the steel and rubber equivalent.

Vibratory loads induced by the impact should be evaluated by means of a specific dynamic analysis of structures and equipment, with account taken of the material properties of reinforced concrete subjected to dynamic loads (stiffness and damping). The floor response spectra should be calculated for all the main structural elements of the buildings which house safety related equipment. Appropriate transfer functions should be evaluated for the estimation of the vibratory action transferred to any safety related equipment. The numerical model should be specifically validated for the dynamic transient analysis, so as to guarantee a proper representation of the vibratory field at least in the frequency range in which the power spectrum of the load function has major contributions. 

A detailed model of the PS system could include the secondary system modeled as reported in Fig. 13 (right) PS principal modal shapes are those reported in Fig. 14a. Alternatively equipments can be modeled by means of mass lumped at pertinent position of the floor as reported in Fig. 13 (center) PS principal modal shapes are those reported in Fig. 14b.

This subsection addresses the evaluation of the models and methods used to develop the floor response spectra (FRS) used for piping and equipment seismic qualification and seismic loads acting on structures. All of the systems required for restart are contained in the reactor building, the stack building, the cooling water reservoir (186 Basin), and the process effluent sump structure. 

The results presented here are for a simplified model where capital cost is based on list costs of all equipment under study, published energy consumption, and replacement parts costs. The model doesn t attempt to quantify soft costs involved in equipment setup times, floor space consumption, downtime, etc. which appear to favor a robotic approach. The capital cost comparison is sensitive to the cost of the robot.
