On December 18, the rotor of Generator No. 1 at Unit 1 of the Tarim Phase II Ethylene Power Plant was installed, as part of the project undertaken by the Tarim Phase II Ethylene Power Plant project team; this marks the completion of the mechanical installation of the plant’s first key piece of equipment. The power station equipment is a crucial system for ensuring the energy supply and operational safety of the Tarim 1.2 million tons/year Phase II ethylene project, and the installation progress of its core equipment – two steam turbine generators with a total generating capacity of 140 megawatts – is under close attention. The equipment consists of components such as bearing housings, cylinder assemblies, as well as the stator and rotor of the generator. The rotor, which is 10.2 meters long, has a maximum diameter of 1 meter, and a lifting weight of 23 tons, extends about 9 meters into the stator; the clearance between it and the stator on one side is only slightly over 10 millimeters. Therefore, extremely high precision in installation and strict control over the installation process are required. To ensure a smooth installation, the project team conducted multiple on-site simulation exercises to analyze the challenges involved in the process and determine the optimal positioning of the rotor. They selected personnel for key roles such as crane operation, hoist control, and gap monitoring, assigning specific individuals to each task, defining clear procedures, and establishing standard commands. On the evening of the 17th, a thorough inspection was carried out on the QHSE protection facilities in the work area, which ensured that the installation could begin smoothly on the 18th. The 15-member installation team worked continuously for 6 hours and completed the rotor installation task 2 days ahead of schedule. It is also reported that for the Tarim Phase II ethylene power plant project, a dedicated team has been assembled to develop specific construction plans for each specialty, based on the remaining work related to the construction of the power plant facilities. Various winter construction measures have been put in place, with a focus on overcoming challenges such as the welding of process pipelines, in order to ensure that all construction milestones are met on schedule.
