Programme overview
Introduction:
Heavy lift engineering decides whether a reactor, column or process module weighing hundreds of tonnes reaches its foundation intact, yet many engineered lifts still rest on misread load charts, rigging chosen by habit and ground bearing checks made after the crane has arrived. This Core Concept course trains engineers and lift supervisors to categorise lifts, select crane configurations, calculate rigging loads, verify ground and wind limits and document the lifting method. Participants produce an Engineered Lift Plan for a case heavy vessel installation.
Course Objectives:
- Classify lifts by weight, utilisation and complexity and decide when an engineered lift plan and independent check are required
- Select crane type, boom length, counterweight and outrigger or crawler configuration from load charts with radius and deduction allowances
- Design rigging arrangements by calculating sling tensions, shackle and lifting beam capacities and load share for asymmetric centres of gravity
- Calculate outrigger and track bearing pressures and specify crane mats and ground preparation against allowable soil capacity
- Assess tandem, multi-crane, tailing and offshore lifts for load transfer, wind limits and dynamic factors
- Compile an engineered lift plan with drawings, calculations, hold points and a communication plan ready for approval
Target Audience:
- Lifting and rigging engineers who calculate and sign engineered lift plans
- Construction and installation engineers who place vessels, modules and structural steel on site
- Lift supervisors and appointed persons who direct critical and multi-crane lifts
- Project engineers who review lifting contractor methods and crane selection proposals
- Heavy transport and logistics engineers who move oversized loads from quay to foundation

Why Attend This Course:
- Return with an Engineered Lift Plan for a case heavy vessel installation, including utilisation, rigging and ground bearing calculations
- Challenge a contractor crane proposal by checking radius, deductions and utilisation against the load chart
- Spot the asymmetric centre of gravity, tilt and upending load changes that overload one sling or one crane
- Compare heavy lift practice with engineers from petrochemical, power, marine and construction projects
Conclusion:
An engineered lift succeeds when crane configuration, rigging geometry, ground support and weather limits are calculated before the load leaves the ground. The course moves from lift categories and crane stability, through load charts and rigging hardware, to sling tension, centre of gravity and ground bearing calculations, then tandem lifts, upending, heavy haul, offshore dynamics and wind. The final day applies these methods to a case heavy vessel and produces an Engineered Lift Plan ready for independent check.
