The storage units, which will increase the terminal’s capacity from 99,100 cubic metres to 231,000 cubic metres, was opened on 4 May, according to Enoc.
The scheme is part of Enoc’s plan to increase activity at the Ulsan port.
The company estimates that petrochemicals imports to northeast Asia will increase from current levels of 25 million cubic metres a year to 40 million cubic metres a year by 2015.
The terminal is connected to the nearby Ulsan petrochemcials complex through 20 separate pipelines.
Enoc acquired 50 per cent in a terminal company owned by the local Taeyoung Industries in 2006 to form Horizon Taeyoung Korea Terminals, the operator of the project.
