Project Background
The new cracker at Shintech's Plaquemine, Louisiana, PVC complex expands Shintech's in-house feedstock output while reducing spot ethylene purchases.The cracker is the last of eight to bring a cumulative 9.74 million mt/year in new ethylene capacity online since 2017.
That total rises to 10.68 million mt/year when including Indorama Ventures' revamped 440,000 mt/year Louisiana cracker and a 500,000 mt/year expansion of Dow Chemical's 1.5 million mt/year cracker in Texas that started up in September 2017.

Outcome
Contracts were awarded for material supply to Mantis Piping in 2018 during the Trump administration's implantation of tariffs on steel. We moved quickly to execute these orders to avoid new tariffs. Materials were ordered six months before being required. Therefore our warehouses in Houston and the UK were utilized to store materials for our client. To streamline the supply, Mantis Piping was awarded a spooling contract which provided one point of contact for our client, allowing us to provide project management value-added services.
