Manila International Container Terminal (MICT) – Berth 7

Manila International Container Terminal (MICT) – Berth 7

In 1988, International Container Terminal Services, Inc. (ICTSI) won the 25+25 year concession to operate the Manila International Container Terminal (MICT), one of the three terminals in the Port of Manila.

Since then, MICT has increased its annual capacity five-fold, becoming the largest and most modern container terminal in the Philippines.

It is now considered at par with the best terminals in the world with its guaranteed efficiencies and modernized operational and administrative systems.

MICT Berth 7 is the expansion project of the existing Berth 6 that will help alleviate congestion at off-dock container yards.

Dextra was involved in the project by supplying 110 sets of Marine Tie Bars, grade 700, bar diameter 85mm as an anchorage to tie back the main concrete wall casted on top of tubular steel piles to a sheet pile anchor wall connected with crane rail beam.

Dextra offers its marine tie bar solution in 3 steel grades, up to a yield stress of 700Mpa and 22 thread diameters, allowing a close match to the performance requirements and an economic use of material.

Aqaba Container Terminal

Aqaba Container Terminal

The Aqaba Container Terminal (ACT) is is located on the northern shores of the Gulf of Aqaba, in the Southern part of Jordan. It is the only container terminal in Jordan, and the second largest on the Red Sea in term of capcity.

Dextra participated to the creation of ACTs new berth between 2011 and 2012, as part of a project which aimed to increase the terminal capacity to 1.2 million TEUs. The expansion started operations in 2013.

For this project, Dextra has been supplying its Marine Tie Rods solutions to BAM International. Rods were supplied in Grade 500 in two different sizes: M105 and M125.

The long tendons were connected to the combi-wall on one side with a Dextra Ball Cage, allowing multidirectional angle of ±10 degrees, which greatly eases the installation process when at the same time addressing possible soil settlement.

On the opposite wall, tie rods were anchored using swivel plate and nuts, set up over waling beams. Dextra swivel accessories also allow a rotation angle of ±7 degrees in every direction.

Port of Douala

Port of Douala

The Port of Douala is a large sea port opened to the Atlantic Ocean, part of the Wouri department in Cameroon. It is the main port of Cameroon and the busiest Central-African Port, with agreements that allow it to serve the countries of Tchad and Central African Republic, which do not benefit from a direct access to sea.

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

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

The rods making the long tendons, up to XXX meters long, were spliced with turnbuckles and couplers. The rods were anchored into the combi walls thanks to the use of Captive Nuts accessories, which allow a multidirectional rotation angle of 5° in order to ease the installation.

Tanger Med 2 Port

Tanger Med 2 Port

Tanger Med 2 is the expansion of Tanger Med, a multipurpose deep-water sea port located in a few kilometers East from Tangier, in Morocco, facing Gibraltar.

The port expansion aims to increase yearly capacity of the port, the largest in Africa, by 5.2 million containers.

For this large infrastructure project, Dextra supporter contractor Bouygues with a rebar splicing solution for the reinforcement of the caissons.

Dextra supplied its Rolltec solution, which is AFCAB-cerfified, a requirement on this project. Two Rolltec machines were installed to support the threading activities: 360,000 threads in total (180,000 Rolltec couplers).

Couplers were use in the reinforcement of the caisson, which were as tall as 20 to 24 meters. Couplers provided:

 

  • Temporary openings to solve congestion issues in the reinforcement within the caisson. Rebar couplers allow to create a safe passage for men and equipment during installation phase.
  • Horizontal wall-to-slab connections (from the inside of the caisson perimeter to slab). For this application, couplers were left pending, allowing the slip form to go up.

Port Autonome de Pointe-Noire

Port Autonome de Pointe-Noire

Port Autonome de Pointe-Noire is a large sea port opened to the Atlantic Ocean and part of the Republic of Congo. The port is connected to the country capital Brazzaville by a 500km rail link.

The seaport plays an important part in the development of the region and contributes to the growth of trade with neighboring countries (Democratic Republic of Congo, Angola, Gabon). More than 600,000 go each year through the port of Pointe-Noire, a figure in constant growth.

To support the ambitious development plan of PAPN, Dextra has been working with contractor SAIPEM for the engineering and supply of the steel structures behind several of Pointe-Noire 16-meters deep quays.

Between 2011 and 2012 for the construction of Quay G, Dextra supplied more approximately 1,000 tons of Marine Tie Rods in Grade 700, the highest in our range. Higher grades offer a higher performance/steel ratio, allowing to pick smaller diameter bar which ultimately provide saving in logistics and installation efforts.

Dextra also supplied the Waling Beams installed onto the Combi Walls. Waling beams act as an interface between the steel walls and the large diameter tie rods. As Waling Beams support the rods, their shape, spacing and installation is very dependent of the tie rods configuration. To guarantee full compatibility and ensure the smooth sequence of installation operation, Dextra always recommend to design and deliver waling beams together with the tie rods assembly.

Later between 2015 and 2016, Dextra participated to a secound round of project delivery for the construction of the Quay D.

MultiRio Container Terminal

MultiRio Container Terminal

The MultiRio Container Terminal is a large container terminal located in the Rio de Janeiro Port. The terminal specializes in the import/export of finished goods.

MultiRio plans to increase its shipping capacity by at least 50% and launch in 2012 an expansion project aiming at adding extra quay length to its infrastructure in order to receive additional port containers.

To support the pier expansion of MultiRio, Dextra has been working with contractor Andrade Gutierrez for the engineering and supply of Marine Tie Rods.

Dextra supplied in 2014, 100 tons of steel rods coming in medium diameters M56 and M59. The rods were anchored to the wall by the use of swivel plates and nuts, which conveniently allow 5° multidirectional adjustment.

Plates are positioned onto the Waling beams, also supplied by Dextra. Waling beams are installed onto the sheet piles. Their design is directly impacted by the Tie Rods solution chosen as for example spacing of the beams will be impacted by the diameter of the bar and angle of the rod.

Sète Port

Sète Port

The Port of Sète is a large sea port opened to the Meditteranean Sea. It is the largest fishing port in the South of France. It also serves many ferry connections towards Tangiers and other destinations in North Africa.

Sète Port and its main sponsor, Region Languedoc Rousillon, wish to increase the container capacity of the port by adding a new quay (Quay H, 15 meters deep) to their existing infrastructure. The new quay will increase both handling and storage capacity of containers.

To support contractor Soletanche-Bachy in the construction of this new structure, Dextra engineered and delivered 74 Marine Tie Rods assemblies. The tie rods systems delivered are the largest currently available in our range: M160.

Large diameter assemblies allow to reduce the number of sets which need to be installed by increasing the spacing between each rod.

The long tie rods assemblies were anchored into the D-Wall by the installation of ball cages, which allow a rotation angle of 10° in all directions.

The Ball Cages were installed into reinforcement of the D-Wall and cast in concrete. After excavation, ball cages were open to allow the reconnection of the threaded ends of the rods.
