At first we assessed the HRSG manufacturer’s operations manuals and drawings. The aforementioned concept encompassed to:

Horizontally lift each module with a horizontal lifting device from an SPMT trailer into an uprighting frame. The uprighting frame itself had a deadweight of more than 40 tons and a length of 30m.
Upright each module inside the uprighting frame with three cranes simultaneously, lift and install each module into the HRSG structure with a height of 27m.

• Calculated load distributions of combination of module and uprighting frame for each crane
• Defined the minimum capacities of each crane for the “three crane lift” and their setups on site: These were
  • 600 tons crawler crane, CC2800-1, 72m main boom, Superlift and Superlift counterweight, Vario-SL necessary
  • 400 tons crawler crane, CC2400, 42m main boom
  • 250 tons all terrain crane, AC250, 42m main boom
• Defined the necessary rigging material
• Defined the applicable SPMT trailer length and capacity: 18 axles of Scheuerle SPMT + 1 PPU
• Defined the necessary cherry pickers
• Defined the minimum crane capacity and setup for discharging the modules in the port. This model was:
  • LR 1400-2, 42m main boom, Superlift and Superlift counterweight
• Assessed and framed logistics:
  • Assessed roads to site and the overall logistics situation that was applicable
  • Assessed the total amount of transports that will enter and leave site frequently for crane mobilization and demobilization: 72
  • Developed a logistics scheduling and procedure
• Assessed and framed necessary HSE criteria to be met

• Created a multi-langualge operations manual for logistics and liftings that explained and illustrated each of the relevant operations and preconditions. That documentation entailed all relevant technical specifiations ready of stress calculation for official approval and served our client as applicable foundation for inquiring the incorporated services.
• Agreed with client’s proof engineering, especially in terms of ground bearing pressures in relation to vertical and horizontal pressures affecting subsurface piling
• Created a isometric three dimensional simulation
• Presented the entire concept twice to our client’s client as ordered by our client
• Coordination and supervision of the entire process during execution including all liftings

Worked out without any technical or HSE-relevant or commercial incident. There was not a single negeative deviation from the planning documents that we elaborated. In contrast, we assumed one module lift each day. In fact, we were partially able to lift two modules each day.

Yes indeed. Through sustainable planning there was no deviation. Since we lifted faster than assumed we reduced downtime and costs dramatically. All stakeholders by means of the project’s particapants and especially our client’s client were totally satisfied. Especially three dimensional simulation of the limited space available for crane mobilization and demobilization as well the uprighting and lifting proactively created a sustainble impression at our client’s client. In other words, through our work our client was holistically exempted from any potential obstacles and problems.
