WHEE successfully completes PT Indonesia Chengtok Lithium EPC project

In line with China's "Belt and Road Initiative" and WHEE’s commitment to supporting Chinese enterprises in going global, WHEE  entered into an EPC contract for a 2x50TPH boiler island with PT Indonesia Chengtok Lithium Indonesia in 2023.

The construction period of the project  kicked off in November 2023. According to the original plan, Unit #1 was expected to be completed by September 2024, and Unit #2 was supposed to be completed by the end of 2024. Facing various difficulties in design, transportation, construction and other aspects in the post-pandemic period, WHEE responded actively by implementing phased management strategies and successfully completed the entire project, earning high  recognition from the client.

Project Progress Review

Early Stage (November 2023 – March 2024):

Under unfavorable conditions such as the rainy season and overlapping civil works, the project team successfully overcame various challenges such as component transportation obstacles and severe high-altitude welding environments. This was achieved through dynamic adjustment of the lifting sequence, installation of rainproof work tents, and implementation of the cooperation mechanism between the Chinese and Indonesian teams. With these strategies, the main steelstructure for both boilers and their respective hydrostatic tests were successfully completed early, providing a solid foundation for subsequent equipment installation.

Middle Stage Challenges (April 2024 – June 2024):

A prolonged rainy season and delays in civil works led to a one-month setback in the handover of work zones for electrical equipment installation, . This caused obstacles on critical paths such as cable and electrical panel installation. The project team immediately activated the following emergency response mechanisms:

1. Optimization of construction resources: Deploying 6 additional key technical personnel from China, coordinating with local labor companies to recruit 20 more  Indonesian technicians, and implementing a night  shift system to accelerate progress.

2. Reorganization of work sequence: Applying the “squeeze in between” construction method to complete work that does not depend on limited areas, such as the installation of cable trays, cable stands, and electrical distribution panel foundations.

Breakthrough at Critical Points

Through coordination among  the project owner, the main contractor, and the civil engineering team, the schedule delays were successfully mitigated by July

The project owner commended us highly, recognizing our hard work during the construction process. We also proactively cooperated with the main contractor to resolve various project obstacles in a timely manner. The owner gave his appreciation for the efficient implementation of the project at critical points and the high quality of the installation, and especially praised our professionalism in integrating the construction schedule with the target time  despite intense time constraints.
