Critical lifts are among the highest-risk operations on any oil and gas project. In Qatar’s Ras Laffan Industrial City and Mesaieed Industrial City — where lifting operations occur daily within live process environments — a thorough critical lift plan is not a bureaucratic requirement. It is what keeps people alive.
This guide outlines the step-by-step process for planning a critical lift on a Qatar oil and gas project, from initial classification through to completion.
| “A well-planned lift is a safe lift. The engineering work done before the crane arrives is what determines whether the operation succeeds.” |
What Classifies a Lift as Critical in Qatar? |
- Load exceeds 75% of the crane’s rated capacity at the required radius
- Two or more cranes are involved in a single lift (tandem lift)
- Lift is conducted over live process equipment or energised systems
- Personnel are required to ride the load or be within the lift zone
- Unusual rigging configurations such as spreader beams or custom lifting frames
- Lifts at extreme radii or with very limited headroom
- QatarEnergy or project HSE plan specifically classifies the lift as critical
The Critical Lift Planning Process |
| 1 | Lift Classification Determine whether the lift meets critical lift criteria. Document the classification decision with supporting calculations. |
| 2 | Scope of Lift Define the load weight, dimensions, centre of gravity, lift height, radius, and pick-up and set-down positions. |
| 3 | Crane Selection
Select the crane based on load chart verification — not estimated capacity. Confirm the crane can safely perform the lift at the required radius. |
| 4 | Engineered Lift Plan A qualified lifting engineer prepares the lift plan including crane configuration, outrigger loads, rigging arrangement, and lift sequence. |
| 5 | Risk Assessment (RAMS)
Identify all hazards — overhead obstructions, ground conditions, weather limits, personnel exclusion zones, and emergency procedures. |
| 6 | Permit to Work
Obtain the required site permit — in Qatar oil and gas environments this is a mandatory step before any crane is mobilised. |
| 7 | Pre-Lift Meeting
Conduct a toolbox talk with all personnel involved — crane operator, riggers, signallers, supervisor, and site safety officer. |
| 8 | Execute and Document
Carry out the lift per the plan. Document any deviations. Complete lift records for project files. |
QatarEnergy and Ras Laffan Specific Requirements |
For lifts within QatarEnergy project environments, the lift plan must typically be reviewed and approved by the project HSE team and in some cases by QatarEnergy’s own lifting authority before work can begin. Third-party verification of the lift plan is often required for critical lifts over certain thresholds. Ensure your crane rental provider has experience working within QatarEnergy environments and can provide the documentation format your project requires.
| TIMELINE | Allow 5 10 working days for critical lift plan preparation, review, and approval in a QatarEnergy project environment. Last-minute critical lift planning is the most common cause of lifting delays at Ras Laffan. |
