The Al-Zour LNG Import Terminal is the world’s largest liquefied natural gas (LNG) import terminal, located 90 kilometers southeast of Kuwait’s capital.

The project included the construction of:

• A re-gasification facility
• Eight LNG storage tanks, each with a capacity of 225,000 m³
• Marine facilities, including two marine jetties and berthing facilities for loading
• Other components such as 14 HP pumps, boil-off gas (BOG) and flare facilities

The facility was expected to produce approximately 22 million metric tonnes (MMT) of natural gas per year and have a storage capacity of 1.8 million m³ of LNG. The liquefaction capacity of the terminal was estimated at 30 billion cubic meters per day (bcm/d).

Dextra’s Contribution to the Marine Facilities:
For this project, Dextra supplied:

• 202 tons of Grade 700 marine tie bars, used as anchors between sheet piles or concrete walls
• 166 tons of waling beams, essential for reinforcing the marine infrastructure

The Al-Zour LNG Import Terminal was completed in November 2021 and reached full operations in February 2022. The terminal now plays a critical role in Kuwait’s energy infrastructure, providing the country with a stable gas network to support energy diversification and sustainable energy initiatives.

The Maitree Super Thermal Power Project is a 2×660 MW coal-fired power station being developed by the Bangladesh-India Friendship Power Company (BIFPCL), a 50-50 joint venture between the governments of Bangladesh and India. The power station is located in Rampal, Bangladesh.

For this project, Dextra supplied more than 400 assemblies of Grade 700 Marine Tie Bar systems to connect piles and waling beams for a 1.2 km-long jetty at the coal power plant.
Dextra’s Marine Tie Bar systems consist of steel bars and anchorage accessories, which function as anchorage to tie back seawalls to anchor walls.

Key Features of Dextra’s Marine Tie Bar Systems:

• Available in three carbon steel grades, with yield stress up to 700 MPa.
• Selection of 24 bar diameters, up to M162, ensuring optimal performance for various project requirements.
• Standard range of anchorage components, allowing easy installation and connection to all types of marine walls.

The construction of the Maitree Super Thermal Power Project began in 2017 and was planned for completion by 2022.

The Karimun Yard is located on the small island of Karimun, Indonesia, less than 25 km from Batam and Singapore. Operated by Saipem, the yard offers over 780,000 sqm of fabrication areas with an annual production capacity of 50,000 tons.

Between 2009 and 2010, Dextra manufactured and supplied large Marine Tie Bars for Saipem, which were incorporated into the main quay wall. Additionally, in 2008, Dextra supplied Marine Tie Bars and Waling Beams, connecting the sheet pile walls of the service jetty.

Marine Tie Bar Systems: High-Performance Solutions:
For the main yard, Dextra supplied its Grade 700 Marine Tie Bars, the highest grade in the range.

• Higher tie bar grades allow for high performance while reducing the size and weight of the bars, making transportation and installation easier.
• Grade 700 also enables design optimization, allowing bars to be spaced further apart, thus reducing the total number of bars required for the project.

Connection & Splicing Systems:
To connect the bars to the walls, ball cages were used.

• When used with a bearing plate embedded in the wall, ball cages allow a multidirectional adjustment angle of 10° for greater installation flexibility.
• To splice bar segments, couplers were also used, ensuring a strong and secure connection.

Visakh Refinery Modernisation Project is a brownfield expansion of the Visakh refinery located in Visakhapatnam, India.

The project will expand the refining capacity from 8.3MMTPA (millions of metric tonnes per annum) to 15MMTPA, while enabling the production and distribution of the fuels that comply with Bharat Stage-VI, a new emission standard instituted by the Government of India.

Dextra was involved in the expansion by supplying Unitec bolted couplers for precast beam connections.

Unitec is a bolted splicing system designed for the connection of two rebars with no thread: its screws will lock both bar ends and complete the connection.

The Visakh Refinery Modernisation project is scheduled for completion in 2020.
