Project Description

The Louisiana-based Green Ammonia construction project marks a groundbreaking venture as the first-ever green ammonia unit built in the United States. Green ammonia, crucial for sustainable agricultural practices and as a potential clean fuel source, underscores the importance of this innovative project. Initiated in March 2023, the project is slated for completion by the end of 2024 and is currently in the commissioning phase.
EXCEL Fabrication has meticulously fabricated all the installed piping, handling a total of 31,681 linear feet of pipe, 230 tons of steel, 1,373 welds, and 2,060 bolt-ups, with mechanical direct hours totaling 71,611. The job's complexity is heightened by the involvement of Teekus, a German engineering firm, necessitating extensive coordination to address missing items and specialty components that resulted in longer lead times. Successful team collaboration has been pivotal in navigating these challenges and ensuring the client and EXCEL teams find efficient solutions and workarounds.
