We implement special construction methods with safe designs to last over 100 years

The design considers variables such as impact conditions of a wreck, seismic load, and wave conditions in 1,000-year frequency. Furthermore, we have implemented SCADA (Supervisory Control And Data Acquisition) and ITS (Intelligent Transport Systems) in case of accidents during use.

A 35-month miracle

It is a 35-month construction miracle accomplished through enthusiasm and incredible technology. Due to the lack of time and shortage of supplies, we had to work closely with our team and partners in order to coordinate with each other. Building this petrochemical plant was a great leap forward in Daewoo E&C’s construction growth.
