Plot Programme and Equipment System
Foreword
For clarity, every bit on this website the discussion Plant is used, then it refers to a Process plant such as a Chemic plant, Petroleum refinery, Gas Processing institute, Petrochemical, Pharmaceutical, Textile, Paper, Semiconductor and Cryogenic plants and related processing plants and terminals.
Drawings, which are shown on this page, are fictitious, but they have been drawn a functional Plot Plan of a Process Institute.
Over the years, I've seen a lot of Plot Plans of several engineering science companies. All these companies evidence a certain standard in their plans, but the layout and dimensioning is often quite different. Also sometimes customers or authorities wants to have additional information on a Plot Plan. For this reason there is no general rule, for a "final" Plot Plan.
Plot Plan
A Plot Programme is a scale drawing that gives an overview (top view) of the entire institute. All roads, buildings, units, tank farms, employee entrance etc. will be given on a Plot Programme. It also listed the true north and Establish north, port address, sometimes prevailing winds, reference point(s), horizontal references etc..
Yous volition empathise that a whole process plant, unremarkably can non exist given on a readable drawing. Therefore, a distinction is made between a Overall Plot Plan and a Detailed Plot Plan.
Overall Plot Plan
A Overall Plot Plan, sometimes this programme called a Site Programme or a Site Master Plan, y'all can compare with a urban center road map. Important buildings, parks and street names are given, simply non the house numbers or the number of rooms in a building.
With the cartoon in your easily, you should discover a certain procedure tank farm and a specific tank, just non a pump or a plate cooler, or heights of buildings, tanks and then on. That kind of equipment and dimensions are non shown on a Overall Plot Programme.
IMAGINARY OVERALL PLOT PLAN
Right down on the drawing you lot tin encounter the starting point of this imaginary Overall Plot Plan.
North starting with N - 000.000 coordinate and East with Due east - 400.000 coordinate.
Both related to an officially recognized reference point, but in practise, the e coordinates refer often to another reference object, and do not beginning with the coordinates Due east - 000.000.
Right on the meridian nether "Notes" you can see the found northward coordinates and (important !) starting reference elevation of this establish is EL.100000. (run into Reference points)
There are no pipe-bridges, pipelines, pumps or other equipment shown on that drawing, but the program gives a good impression of a overall procedure plant.
Detailed Plot Program
In contrast with a Overall Plot Plan, a Detailed Plot Plan gives a overview (meridian view) of a part of a process plant. Generally it shows a office of a certain area, floor or unit.
Every bit you might have seen on the overall Plot Plan, the process building is largely equipped with a roof, and only some equipment parts are visible from above.

The programme shows the whole quaternary floor on a pinnacle of EL.129200. These meridian are related to the upper role, Acme of Concrete (T.O.C.) of the 4th floor of the FM-AREA, and indicates a elevation of 29200 millimeters from the starting point (EL.100000) of the procedure plant. Furthermore, it shows some equipment, a large pipeline and some smaller, a staircase and the columns of the steel construction of the building.
Sentry out, that all East and North dimensions, starting at the center lines of the columns.
A major advantage of a proper detailed Plot Programme is that you can determine from your role, or a new piece of equipment in a certain area, floor or unit, can be placed. That withal merely applies to the horizontal dimensions, because y'all cannot run into possibly obstructions in the vertical level.
What you also cannot encounter on a Plot Plan, are the elevations of the equipment. That means that yous do not know, or a device on the fourth flooring or may be already on the third floor begins...for this reason, Equipment Arrangements have been considered.
What is a Equipment Arrangement..
Equipment Arrangements are drawings, which show the superlative and side-view of a part of a process institute. The top-view is similar to a detailed Plot Program, except that only equipment is shown.
Both equipment arrangements shows the equipment in a particular area, and sometimes a few details effectually a specific device. With a drawing of a site-view you tin come across the elevations of a certain device, and if the device is going through i, or more floors.

Summary
Plot Plans and equipment arrangements are resources to aid determine relative and specific positioning of equipment on a process plant, related to the plant due north, that on the drawings must be shown.
Both assistance the development of support facilities and are used to make up one's mind the almost cost-effective structure sequence and methods. They are also used for operational needs, such equally grooming and emergency access, and are essential for obtaining permits and determining environmental and personnel safety. They are the primary documents used in assessing fire protection and if necessary, to obtain government permits..
Plot Plans and equipment arrangements are dynamic documents and evolve further during the structure stage and the lifetime of a process institute.
