Last week the last major module for the Acid Plant was installed at Wet Gas cleaning Stage 1. Although the installation was delayed by a few days due to unfavourable wind conditions, Module 119 was safely landed last Tuesday morning.
Weighing in at 250.9 tonnes and being 24.1 high by 24.0 long and 16.1 wide, the total lift with rigging was 367.8 tonnes. The complicated lift went well and took 5 hours to place the module on the foundations as it had to be manoeuvred over the top of the wet gas cleaning quench tower and supporting steelwork. At times there was only 60 millimetres clearance between the module and the fibreglass quench tower.
The heavy lift crane will now complete installation of the remaining modules and the roof for the TSL building.
In parallel with these major lifts there will also be a requirement to install structural steel to join the modules as the height of the TSL building increases. This will mean another crane capable of lifting structural steel into position (over the top of the last module) and down into the middle of the building will be required. – note that the height at the top of the last module is 78 metres above ground level.
The new crane will be assembled on site where the 137 metre long boom will be built on the ground between the site medical centre and the southern side of the TSL building. We will also soon see TSL module 84 installed.
