Energy plant area focuses on the development of economically feasible and optimal structure systems for LNG / LPG storage tanks, land and offshore plant pipes, pipe structures, and wind support structures.

Energy pipe simulation technology is a technology that predicts changes in physical properties of pipes for different manufacturing methods such as JCO, UOE, roll bending, ERW and spiral. We conduct research to suggest optimal material and piping conditions for our clients.

Offshore plant and wind power sectors have developed cold formed bending technology on AB/EQ70 material (70mm thickness) to manufacture high quality and high precision jack-up rigs. We developed Warren truss jacket and transition piece for offshore wind power generation to reduce weight of steel material, quantity of welding and construction period compared to the conventional X-brace jacket system.
