Downer Clough awarded ECI contract for CSBP NAAN3 Project

Engineering and construction company Clough Limited (ASX:CLO) today announced that the Downer Clough Joint Venture (DCJV) has been awarded an Early Contractor Involvement (ECI) contract by CSBP Limited for the Ammonium Nitrate/Nitric Acid Plant Number 3 (NAAN3).

DCJV is a 50:50 joint venture between Clough and engineering and infrastructure management services group, Downer EDI Limited (Downer).

The scope of work for the ECI phase involves a detailed review of current engineering and procurement documentation in collaboration with CSBP, to establish an execution plan and budget for the Engineering, Procurement and Construction (EPC) phase of the NAAN3 project which forms part of CSBP’s wider ammonium nitrate expansion proposed for its site in Kwinana, Western Australia.

“Clough has a long history with the Kwinana strip and is pleased to be returning to assist CSBP with the NAAN3 project. Successful completion of the ECI phase of this project will position Downer Clough for the EPC phase, which has an initial estimated value of approximately $200 million. We will work closely with our valued partner Downer to bring the best Australian engineering and project management resources to this important project” said Clough’s Chief Executive Officer John Smith.

The Chief Executive Officer of Downer, Grant Fenn, said Downer had carried out construction works for CSBP on both the Prill Plant and NAAN2 Project at Kwinana.

“We look forward to working closely with our joint venture partner, Clough, and strengthening our relationship with CSBP on this important project,” Mr Fenn said.

The NAAN3 project will be undertaken on the existing CSBP site in Kwinana, Western Australia, and will significantly enhance the ammonium nitrate production capability of the facility, and the ability of CSBP to service the growing resource industry demand for ammonium nitrate in WA.
