  • The Al-Zour LNG terminal

Krybar® in the Al-Zour LNG project in Kuwait

As from 2020, Kuwait will have a new liquefied natural gas (LNG) terminal, located near Kuwait City which will produce approximately 22 million tonnes of natural gas every year. For the construction of this impressive facility, ArcelorMittal Special Rebars & Thread Bars and ArcelorMittal Projects work jointly to supply Krybar®, a special concrete reinforcing steel bar providing safety for cryogenic applications.

A liquefaction capacity of 30 billion m3 per day

The Al-Zour LNG terminal is located in the Al-Zour region, about 90 km south of Kuwait City, close to the border with Saudi Arabia. This project includes the construction of a re-gasification facility, eight storage tanks and marine facilities.

Once completed and fully operational, the Al-Zour LNG terminal will have:

  • a production capacity of 22 million tonnes of natural gas every year
  • a storage capacity of 1.8 million m³ of natural gas
  • and a liquefaction capacity of 30 billion m3 per day

The owner of the project is Kuwait National Petroleum Company (KNPC), a subsidiary of Kuwait Petroleum Corporation, which awarded Hyundai Engineering & Construction Co., Ltd. (HDEC) – a consortium including Hyundai E&C and state-owned Korea Gas Corporation (KOGAS) – for the construction of the terminal.

The biggest supply contract ever booked for Krybar®

ArcelorMittal Special Rebars & Thread Bars teamed up with ArcelorMittal Energy Projects (Oil&Gas) in Singapore to provide Krybar®, a durable reinforcing steel capable to resist low temperatures up to -170°C.

During the early bidding stage in 2015, ArcelorMittal Projects Oil & Gas in both Singapore and Korea followed the project closely. They promoted Krybar® and supported various EPCs, with, amongst others, Hyundai Consortium. In February 2016, Hyundai Consortium was awarded the EPC contract, and their Korean partner, KOGAS, was then entrusted to the design of this major ‘Design & Build’ contract.

After a successful visit of KOGAS’ technical delegation to ArcelorMittal Warszawa (Poland) in 2016, Krybar® was finally approved for the project.

In total 5,520 tonnes of Krybar® 620 (in 20mm, 25mm and 28mm diameters) produced by ArcelorMittal Warszawa will be supplied for the construction of the eight storage tanks, each with a capacity of 225,000 m³. This project represents thebiggest supply contract ever booked by ArcelorMittal Europe – Long Products and ArcelorMittal Projects for Krybar®.

Krybar® in more than 300 tanks worldwide

Krybar® is a special concrete reinforcing steel designed on demand of the LNG industry in order to provide safety for cryogenic applications. Its special composition and rolling process give Krybar® a high ductility even at very low temperature, down to -170°C, making it ideal for the construction of gas tanks (LNG and LPG) and ethylene tanks.

ArcelorMittal offers a wide range of Krybar® grades depending on the design temperature of the tank:

  • Krybar® 50 for LPG tanks with temperature down to -50°C
  • Krybar® 105 for Ethyl tanks with temperature down to -105°C
  • Krybar® 620 & Krybar® 165 for LNG tanks with temperature down to -170°C

ArcelorMittal has been producing Krybar® since 1980. Since July 2014, its production takes place in the new rolling mill of ArcelorMittal Warszawa.
