The Port of Douala is a large seaport located on the Atlantic Ocean, in the Wouri department of Cameroon. It serves as the main port of Cameroon and is the busiest port in Central Africa. Through agreements, it also serves countries like Chad and the Central African Republic, which lack direct access to the sea.

To support the ambitious development plan of Port Autonome de Douala, Dextra collaborated with contractor BESIX for the engineering and supply of the steel structures supporting Douala Pier 51, a 165-meter-long quay wall.

In 2015, Dextra engineered and supplied Marine Tie Bar systems with a diameter of M100 and in Grade 700, the highest in our range. Higher grades offer an improved performance-to-steel ratio compared to grades 355/510 and 500/660, allowing for smaller diameter bars, which ultimately provide steel savings and facilitate logistics and installation.

The long tendons were spliced with turnbuckles and couplers. The rods were anchored into the combi walls using Captive Nuts accessories, which allow a multidirectional rotation angle of 5°, easing the installation process.

Paradip International Cargo Terminal (PICT) is a multipurpose berth located at Paradip Port on India’s eastern coast, designed to handle clean cargo. The berth has a depth of 17.1 meters and a length of 450 meters, allowing it to accommodate cape-sized vessels up to 125,000 DWT. It will handle a range of cargoes including containerized goods, iron and steel products, fertilizer, food grains, and sugar.

Dextra supplied approximately 370 tons of Marine Tie Bar systems, sizes M105 and M76, Grade 500, along with accessories like couplers, turnbuckles, swivel plates, and swivel nuts. These tie bar systems were used to secure the concrete diaphragm walls at both ends of the berth, ensuring the structural integrity of the terminal.

.

With the new berth becoming operational in 2018, Paradip Port now boasts a total of 18 berths, including 13 cargo berths, 2 oil tanker berths, and 3 crude oil tanker berths with a single-point mooring system for handling crude oil tankers. This expansion significantly enhances the port’s capacity to handle a wide range of cargo and oil shipments.

Mugharraq Port, located 240 kilometers from Abu Dhabi, UAE, is undergoing a significant marine development project. The expansion includes extending the quay wall to 480 meters, deepening the facility to 8 meters, and adding six Ro-Ro ramps and additional berths to facilitate heavy lift operations.

Dextra supplied 407 tons of marine tie bars (size M103, grade 700) to connect the sea walls to the anchor walls.

This project aims to enhance the port’s infrastructure and service capabilities, better supporting offshore and mega projects in the oil and gas industry.

Altamira Port, located on the Gulf of Mexico in Tamaulipas, Mexico, is a key hub connecting with 125 ports worldwide. It handles a wide range of cargo, including liquid and dry bulk, petrochemicals, LNG, containers, and general cargo, serving an important industrial and economic region.

As part of its expansion to strengthen Mexico’s position as a global logistics platform, Dextra supplied 174 tons of grade 700 marine tie bars to anchor the sea walls during the project.

Additionally, Сонитек, a sonic tube solution, was used for CSL (crosshole sonic logging) testing of foundation piles in the quay. This technique ensures the structural integrity and homogeneity of concrete in the piles by measuring the speed of ultrasonic pulses.

Порт Сет, расположенный на Средиземном море, является крупнейшим рыболовецким портом на юге Франции, а также обслуживает многочисленные паромные маршруты в Северную Африку, включая Танжер. В рамках своих усилий по увеличению контейнерной мощности порт добавляет новый причал (причал H) глубиной 15 метров, чтобы улучшить как обработку, так и хранение контейнеров.

Для поддержки подрядчика Soletanche-Bachy в строительстве этого нового причала компания Dextra спроектировала и поставила 74 крупных Морской галстук-бар сборки, самые большие в нашем ассортименте на M160. Эти сборки большого диаметра уменьшают количество требуемых наборов за счет увеличения расстояния между каждым стержнем.

Стяжки были закреплены в D-Wall с помощью шариковых сепараторов, которые допускают угол поворота 10° во всех направлениях. После выемки грунта шариковые сепараторы были открыты, чтобы обеспечить повторное соединение резьбовых концов стержней.
