The heaviest item to be installed at BP Zhuhai was the CT232 Dehydration Tower, weighing 655Te and a height of approximately 58.4m. Prior to installation, the Tower was tailed from the horizontal to the vertical using two cranes, TerexDemag CC8800-1 main crane and TerexDemag CC5800 tail crane. Once the Tower reached vertical, the tail crane was released and the main crane, configured with 600Te of superlift counterweight, completed the installation. During the installation, the Tower was required to be carefully manoeuvred above and between existing structures with minimal clearances on 3 sides of the Tower foundations.
Prior to the installation of Silo Cone CF610, weighing 352Te, the Silo Cone was required to be rotated vertically through 180° using two cranes, Sany SCC16000 main crane and TerexDemag CC2800 tail crane. Once rotated to vertical, the tail crane was released and the main crane, configured with 560Te of superlift counterweight, completed the installation into the Silo structure, hoisting the Silo Cone to a height of approximately 98m.
