Fujairah Port: A Key Maritime Hub in the UAE

The Port of Fujairah, located in the emirate of Fujairah on the Gulf of Oman, is the only multi-purpose deep-sea port on the eastern seaboard of the United Arab Emirates (UAE). Strategically positioned 130 km south of the Strait of Hormuz, it serves as a crucial gateway for international trade and energy exports.

Dextra was involved in the expansion of the port between 2007 and 2008.

Oil Terminal 2 (OT2)

For the new Oil Terminal 2 (OT2), Dextra engineered and supplied the Системы морских стяжек used for the anchoring of the Main Quay walls.
More than 1,400 tons of tie bars were provided for this large-scale project.

Южные причалы волнолома

In 2008, Dextra also engineered and supplied Marine Tie Bar systems for the anchoring of the Tugs Jetty, Craft Docks, and Main Quay Wall. Short Морской галстук-бар assemblies were installed between King Pile Walls.
To facilitate transportation and installation, high-performance Grade 700 steel was selected, allowing for a higher level of performance with relatively smaller diameters.

Плотина Чагла

Chaglla Dam is a hydroelectric dam built on the Huallaga River in the Huánuco region of Peru. The dam stands 203 meters high and has a maximum installed capacity of 456 MW.

For this major dam project, Dextra consistently supplied its Rolltec rebar coupler solution to Brazilian contractor Odebrecht from 2012 to 2015.

Rolltec is the most popular rebar splicing solution in Latin America, offering a competitive alternative to lap splices.

Rebar preparation is supported by a unique lightweight machine, which can be operated by a single person. The Rolltec machine is relatively easy to transport and convenient to install, even in remote locations such as dam construction sites.

Beyond just couplers and equipment, Dextra also took charge of machine commissioning and operator training, ensuring the contractor’s team made the most of their rebar coupler solution.

Petronas RAPID: A Strategic Petrochemical Complex in Malaysia

Petronas RAPID (Refinery And Petrochemical Integrated Development) is a large-scale petrochemical complex located in the southernmost part of Johor, Malaysia, across the sea from Singapore.

Commissioned in 2016, the RAPID development aims to increase local production capacity by 300,000 barrels per day, making it a strategic asset for the Malaysian peninsula.

Для этого проекта компания Dextra предоставила свое Бартек system for the construction of precast pipe racks across the site. A total of 30,000 Бартек Бары во главе were used to create horizontal anchoring points for pipe rack beams.

To support the project, a Бартек machine was installed directly on-site and commissioned by the Dextra team, ensuring efficient bar preparation and seamless integration into the construction process.

Cylingas Reservoirs: Industrial Gas Storage in the UAE

The Cylingas gas tanks are part of the industrial complex of Cylingas, located in Al Quoz, United Arab Emirates.

For the installation of new gas tanks, Dextra supplied its tension rods systems, which were used for the cross-bracing of the tank footing structure. Carbon steel rods in Grade 355, with a diameter of 120 mm (thread M123), were selected for this application. The rods were delivered with forks, lock covers, and turnbuckles. A total of 48 sets were installed for this project.

The assemblies were fixed onto the pylons using gusset plates connected to the forks. Turnbuckles were installed in the lower part of the assembly to facilitate installation, allowing for length adjustment and stress control by bringing two bar segments closer together.

For more information on Tension Bars in industrial settings, please download our dedicated introduction brochure.

Jamnagar Refinery Expansion: The World’s Largest Refinery by Production Capacity

Located in Gujarat, western India, the Jamnagar Refinery is the largest refinery in the world by production capacity. Owned by Reliance Industries, it was commissioned in 1998 and spans a vast 50 km² area.

For Phase 3 alone, more than 305,000 tons of steel подкрепление were used in a 36-month project, involving over 100,000 engineers and construction workers.
Dextra has been involved in Jamnagar since the early phases, supplying rebar splicing solutions for Phases 1, 2, and 3 of the project.

Dextra’s Rebar Splicing Solutions for Phase 3:

Three rebar coupler solutions were used in Phase 3:

  • Bartec Solution
    Used for cast-in-situ applications, including bar-to-bar connections in foundations, pile cages, and column cages.
    Also utilized in heavily congested rafts and pile caps to facilitate efficient стыковка арматуры.
  • Groutec Couplers
    Applied to pipe racks, which were constructed from сборный elements in a dedicated сборный factory within the project.
    Positioned in the bottom elements and filled with grout, eliminating the need for in-situ wet суставы and ensuring fast, secure connections between beams and columns.
  • Unitec Couplers
    Used in applications where rebar length was too short to allow traditional overlap connections.

Канал по смягчению последствий наводнения в Джизане

The Канал по смягчению последствий наводнения в Джизане is an ongoing infrastructure project in Jizan Economic City, Saudi Arabia.

Located along the coastline, the city is at risk of flooding due to frequent torrential rainfall. The flood channel plays a crucial role in protecting downstream areas from major flood damage.

As the channel will be exposed to seawater and environmental contaminants that can accelerate steel corrosion, Dextra ASTEC glass fiber-reinforced polymer (GFRP) rebar was chosen as the ideal solution for the project. Nearly 2 million meters of GFRP rebar were supplied.

ASTEC GFRP rebar это corrosion-free, non-metallic reinforcing bar that offers higher tensile strength than steel while being significantly lighter in weight.

Upon completion, this project will be the world’s largest construction using GFRP rebars as concrete reinforcement.

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.

Гидроаккумулирующая электростанция Хатта

Проект гидроаккумулирующей электростанции Хатта расположен недалеко от поселка Хатта в горах Хаджар, в 140 км к юго-востоку от Дубая.

Станция будет использовать воду, хранящуюся в верхнем водохранилище плотины Хатта, применяя технологию гидроаккумулирования с насосами на солнечных батареях из солнечного парка Мохаммеда бин Рашида Аль Мактума.

Проект был присужден консорциуму, в который входят STRABAG Dubai LLC, STRABAG AG, австрийская Andritz Hydro и оманская строительная компания Ozkar. Французская EDF выступает в качестве консультанта проекта.

Он будет включать турбинный вал диаметром около 36 метров и глубиной около 70 метров, предназначенный для размещения двух турбин с общей ожидаемой выходной мощностью 250 МВт. Кроме того, будут вырыты напорный туннель длиной 1,2 км и два автодорожных туннеля длиной около 470 метров и 440 метров.

Компания Dextra участвовала в рытье гидротоннелей, поставив тысячи стальных болтов GEOTEC™, в том числе Самосверлящие анкерные болты, почвенные гвозди, и комбинированные болты, диаметром от 22 до 32 мм, для укрепления скальных массивов и склонов.

Системы стальных анкеров GEOTEC™ компании Dextra подходят для различных грунтовых условий и применяются в таких областях, как строительство дорог, гидроэлектростанций, подземных хранилищ нефти и газа, подводных и канализационных туннелей.

Проект планируется сдать в эксплуатацию в начале 2024 года.

Это часть Стратегии чистой энергии Дубая 2050, цель которой — к 2050 году обеспечить 751 TP3T от общего объема выработки электроэнергии в Дубае за счет чистых источников энергии.
