Terminal da Refinaria de Jizan

Jizan Refinery Terminal: A Major Oil Infrastructure for Saudi Aramco

The Jizan Refinery & Terminal is a large-scale oil megaproject built for Saudi Aramco in the Jizan Economic Area, located on the Red Sea, on the west coast of Saudi Arabia.

For this project, Dextra engineered and manufactured marine tie bars systems, which were used in the construction of the quays of the marine terminal.

In total, Dextra delivered 412 tie rod sets in size M98. The Grade 500 steel rods were connected to combi walls on both sides using Dextra-designed captive nut accessories, which were cast into the concrete piles. Captive Nuts allow a 5° angle of adjustment in all directions, ensuring flexibility during installation.

Each assembly, measuring up to 36 meters in length, was divided into three main segments and reconnected using couplers and hinge couplers for efficient transport and installation.

Terminal de importação de GNL Al-Zour

Al-Zour LNG Import Terminal: The World’s Largest LNG Import Facility

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.

Projeto de superenergia térmica Maitree

Maitree Super Thermal Power Project: A Bangladesh-India Joint Initiative

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 Sistemas de barras de amarração marítimas 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.

Pátio Karimun

Karimun Yard: A Key Fabrication Facility in Indonesia

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 Barras de gravata marítima 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 Barras de gravata marítima, the highest grade in the range.

  • Mais alto 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.

Caverna de GLP Hyosung

Caverna de GLP de Hyosung: Um Projeto de Armazenamento Petroquímico em Grande Escala

Este projeto multifásico, desenvolvido pelo Hyosung Group, inclui a construção de:

  • Uma planta de produção de desidrogenação de propano (PDH)
  • Uma planta de polipropileno (PP)
  • Um tanque de armazenamento de gás liquefeito de petróleo (GLP)
  • Armazéns para GLP e produtos petroquímicos

Todo o complexo ocupará 60 hectares dentro da Zona Industrial Cai Mep em Ba Ria-Vung Tau, perto da Cidade de Ho Chi Minh, no Vietnã.

A Dextra está apoiando a construção da unidade de armazenamento subterrâneo de GLP de 240.000 toneladas, fornecendo 30.000 unidades de parafusos de rocha de polímero reforçado com fibra de vidro (GFRP). Esses parafusos são usados para consolidar a face rochosa da caverna ao redor da área de escavação de 150 metros de profundidade.

Para prevenir eficazmente o vazamento de petróleo, a água do mar será injetada na rocha circundante, criando uma cortina d'água. Dado o ambiente altamente corrosivo, Parafusos de rocha GFRP são a solução ideal devido à sua resistência à corrosão.

Vantagens do Dextra Parafusos de rocha GFRP:

  • Âncoras de mineração cortáveis baseadas em tendões GFRP totalmente roscados
  • Disponível em sete diâmetros (variando de 20 mm a 40 mm)
  • Entregue com placas e porcas de GFRP
  • Leves, facilitando o manuseio, transporte e instalação dentro do túnel

A expectativa é que as instalações entrem em operação comercial em 2020.

Modernização da Refinaria Visakh

Modernização da Refinaria Visakh

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.
