The shipping company’s engineering team partnered with Austrian steel products manufacturer voestalpine Grobblech to design the LCO2 tank with an optimal storage tank material.

The LCO2 tank, made using voestalpine's 'toughcore' steel, can withstand temperatures down to -80°C, the steel products manufacturer said. With the appropriate combination of thickness and toughness, the material used to build the tank is thermomechanically rolled with heavy plates, it further added.

It is imperative to achieve a balance in pressure and deep temperatures, in order to liquefy CO2 and at the same time prevent dry ice formation in the tank, especially when transporting it by ship, voestalpine Grobblech said.

“The actual designs at medium pressure and temperatures down to -40°C cover capacities up to 7,000 cbm for a single tank,” HB Hunte said. “The overall ship's cargo capacity ranges up to 36,000 cbm,” it further added.
