1.0 PURPOSE

The purpose of this GI is to protect personnel and high clearance equipment moving under, or operating near,overhead power-lines and to prevent damage to power-lines or unscheduled interruption of the power supplyduring such operations.

2.0 SCOPE

This General Instruction shall apply to all Saudi Aramco proponent departments and contractor companiesmoving high clearance equipment and loads under, or operating equipment near, power-lines, regardless of

power-line location, voltage rating, or the type of equipment involved. This GI does not apply to moving mobilecranes along roadways where overhead power-line crossing heights are posted and/or equipped with telltalesindicating safe overhead clearance.

LINE VOLTAGE ABSOLUTE LIMIT OF APPROACH

Up to 250,000 volts 6.1 meters (20 feet)

Over 250,000 volts 7.6 meters (25 feet)

8.2.3 If the crane operation includes lifting near energized power-lines, it shall be considered a critical lift andrequires an approved Critical Lift Plan as per GI 7.028. The Critical Lift Plan shall be prepared by aRigger-I or rigging competent person with PDD participation and co-signed by the facility proponentdepartment and PDD.

8.2.4 Crane lifts near energized power-lines shall not be performed in wind speeds exceeding 32 km/h (20mph 17.4 knots), unless otherwise specified by the crane manufacturer. No crane lift shall be

performed if the Wet Bulb humidity is above 80%.

8.2.5 Use of a personnel platform (manbasket) near an energized power-line shall be done as a last resort and

shall not to be used, unless all other options (scaffolding, manlifts, etc.) have been explored and foundunacceptable. The use of a personnel platform (manbasket) shall be considered a critical lift andrequires an approved Critical Lift Plan as per GI 7.028. Use shall be approved through PDDs

concurrence on the work permit. (Refer to GI 7.027 and 7.028)

8.2.6 Operation of the crane boom or personnel platform (Manbasket) over power-lines shall be approvedwith PDDs concurrence on the work permit.

8.2.7 Electrical system protective devices that automatically re-energize the circuit after a power-line contactoccurrence shall be blocked or disengaged to inhibit this function.

8.2.8 Load control, when required, shall utilize non-conductive taglines near energized power-lines.

8.2.9 Non-conductive barricades shall be used during the crane lift near an energized power-line to restrictaccess to the crane work area for personnel other than lifting crew. All combustible and flammablematerials shall be removed from the vicinity of the energized power-line.

8.2.10 No one shall be permitted to touch the crane or the load near energized power-lines, unless the Rigger-I or a competent person indicates it is safe to do so.

8.2.11 Use of a crane to move loads near an energized power-line shall be considered as a last resort and theyshall not to be used unless all other options (forklifts, flatbed trucks, skids, etc.) have been explored and

found unacceptable. If a crane must be used, it shall be considered a critical lift and requires anapproved Critical Lift Plan, as per GI 7.028. Use shall be approved through PDDs concurrence on thework permit. (Refer to GI 7.027 and 7.028)

9.0 MOVING OVERSIZED EQUIPMENT

The proponent department shall prepare a Move Plan that shall include drawings, showing the overalldimensions of the equipment mounted on the vehicle and the proposed route to be taken. If the route is to

cross under power-lines, a PDD representative shall be included in the development and approval of theMove Plan. Clearances shall conform to those listed in paragraph 5.1.1. Prior to the move, the proponent

department shall prepare and obtain PDDs concurrence on the Oversized Equipment Pre-Move Checklist(Attachment 2).
