PLOTPLAN SPACE REQUIREMENTS

Copyright ©2009, Fluor Corporation. All Rights Reserved. Electrical

PURPOSE

This document establishes guidelines to define the space requirements for Electricalequipment during plotplan development by Piping.

SCOPE

The guideline describes the items to be addressed, in order to have an optimal plantlayout, which is based on:

• Health, Safety and Environmental (HSE)• Authority/local requirements• Economics• Ergonomics• Practicality• Cost saving aspects• Specific client requirements

APPLICATION

All projects.

RESPONSIBILITY

The Project Lead Electrical should assign a task force member as originator, who isresponsible to provide the input to Piping with regard to electrical equipment and itemsrequiring space.

GENERAL GUIDELINES

Substation/Transformer Yard

Assess substation/transformer yard dimension, based on equipment information derivedfrom the key single line diagram, and locate facility adjacent and as central as possible tothe plant.

Possible locations are:

• outside the roads surrounding the plant,• Inside the roads surrounding the plant, provided that any impact caused by the

explosion hazardous area classification and fire hazard classification is observed• close to piperacks to easy overhead cable installations

Observe facility location with regard to prevailing wind.

Allow for safety-, working clearance and future facility extension.

Ensure free space around building entry for unloading and access for heavy equipmentthrough ramps, alleys, doors and neighboring structures.

Observe interference of major cable trenches interfacing with the facility or plantequipment.

Buildings General

Allow for safety and easy building access.

Note:

Dimensions of major equipment shall be based on vendor catalogue information andshall be used to define building sizes. Include clearance distances and future space tocome to a preliminary building size. Examples of major equipment and requirements thatmay have major space impacts are:

• MCC/SWGR's/Transformers/UPS/VSDS systems• Allow for safety and operation clearances around equipment• Allow for maintenance areas around equipment were required, include space to open

doors

Equipment in Plant Areas

Assess dimensions of major electrical and control system equipment associated with

process/mechanical equipment, based on vendor catalogue information and outlineestimated space requirement on layout. Examples of major equipment that may havespace impacts are:

• MW drives having auxiliary equipment such as captive or unit transformers, VSDS,local panels, etc.

• Allow for safety, working clearance and maintenance area around equipment,include space to open doors

• Consider adequate space for large size cable bends or sleeves requiring a large radiusto connect MW drives

• Corridors for high tension conductors and its interface / clearance with otherfacilities

• Space for busducts / supports• Requirement of batteries / acid storage rooms• Storage space for spares / warehousing• Operator's room.

Assess underground trench or cable tray dimensions, outline and locate trench corridorsor cable tray space requirements plant wide, based on (preliminary) required number of HV/MV/LV feeders, motor-, and associated control cables. Preferred location of maincable trenches onplot are under pipe racks, offplot along roads.

Asses space for main cable tray riser racks in front of substations.
