ABS design review complete

LNG Industry,

ABS Consulting has carried out design review services for an approval in principle of the design of Hyundai Heavy Industries' (HHI) modular liquefied natural gas (LNG) storage tanks.

ABS reviewed the system design for HHI's modular LNG storage tank and its construction with onsite personnel. During the design review process, the company reviewed the design against applicable rules and standards. HHI's design methodology was confirmed as technically equivalent to conventional onshore LNG storage tanks.

HHI is applying spin-off technology and concepts from LNG shipping to onshore storage for the construction and assembly of the modular LNG tanks. As the demand for energy storage grows, in particular in remote and harsh environment areas, innovative approaches are crucial in creating new possibilities for various industries.

The tanks will undergo the majority of the construction phase in the controlled environment of a shipyard, with sections then shipped around the world. This approach allows for a minimal amount of construction effort and time at the final installation site.

Once the sections are onsite, HHI estimates that final assembly can be completed in about six months. In arctic areas where the construction season can be as short as three months, this can result in storage tanks being ready in as few as two building seasons.??

Decreasing construction time

Tom Nolan, Vice President of Global Maritime Services at ABS, said: "We are proud to help HHI with this new approach to LNG storage tank construction. This method may play a significant role in decreasing the time it takes to complete construction in arctic areas where extreme weather conditions limit the timeframe during which construction can take place."

HHI expects that the new modular LNG storage tank will reduce both the EPCC cost and the construction period. "It is to be one of the solutions to overcome excessive investment cost and can also enhance the compatibility of the ground LNG liquefaction plant in the developed markets such as Australia, Canada and the US," said Chun In-soo, COO of HHI's Industrial Plant & Engineering Division.
