The Queensland Curtis LNG (QCLNG) project is located on Curtis Island, Gladstone, in Queensland, Australia, involving conversion of coal seam gas (CSG) reserves into LNG and expansion of exploration and development of CSG reserves in southern and central Queensland.

The gas field, pipeline, LNG plant, swing basin and channel, and shipping operations are all part of the project development. The project’s construction began in late 2010.

Dextra contributed to the project by delivering 307 tons of marine tie bars and accessories in grade 460. The tie bars serve as an anchorage for the marine offloading facility’s anchor walls.

Bang Pakong Power Plant is Thailand’s first power plant using natural gas from the Gulf of Thailand as main fuel.

Located on the left bank of the Bang Pakong River in Chachoengsao Province, it comprises both thermal units and combined cycle blocks, with a total capacity of 2,490 MW*.

The plant is built to compensate for the power-generating capacity that was lost after the 1,050-megawatt Bang Pakong Combined Cycle Power Plant was terminated in 2014.

Dextra supplied a wide range of Bartec rebar couplers from size 12mm to 32mm, for the construction of the plant’s cooling tower and combined cycle blocks. The couplers were used to reinforce and connect precast columns and precast beams.

Moreover, Groutec couplers were installed in precast columns for a fast and easy connection with the foundation at the construction site: once the precast columns are lifted and placed into position, the embedded couplers are injected with grout.

The LNG Dunkirk Terminal is a new natural gas built in the North of France. The project belongs to EDF (France’s main energy company), Fluxys & Total. The new LNG Terminal facilitates the importation of liquid natural gas (LNG), which is transported at low temperature at -163°c. The terminal aims to answer the growing French and Belgian consumption of natural gas, answering 20% of the national consumption of the two European markets. It is the second largest LNG terminal in continental Western Europe.

For this major energy infrastructure project, Dextra collaborated with Bouygues Travaux Public for the supply of Griptec, Dextra’s most advance rebar splicing solutions. Dextra supplied the Griptec sleeves while our local network of fabricators serviced the bar end preparation.

Griptec was used for the three reservoirs external walls in vertical applications. Griptec Headed Bars were also installed in congested areas as substitute to hook bars.

Griptec was also used on various part of the project to create temporary openings, which allow the movement of men and equipment though the reinforcement. For more information about similar application, please refer to Tanger Med 2 Port project, also by Bouygues.

For more information about the availability of Griptec and rebar splicing solutions in Western Europe, please contact our Paris office.

Port of Fujairah, in the emirate of Fujairah and strategically located on the Gulf of Oman, is the only multi-purpose deep sea port on the Eastern seaboard of the United Arab Emirates. It is located just 130 km South from the Strait of Hormuz.

Dextra has been involved in the expansion of the port between 2007 in 2008.

Oil Terminal 2

For the new Oil Terminal 2 (OT2), Dextra engineered and supplied the Marine Tie Bars systems used the the anchoring of the Main Quay walls.

More than 1,400 tons of bars have been provided for this large project.

South Breakwater Berths

In 2008, Dextra also engineered and supplied the Marine Tie Bars systems anchoring Tugs Jetty, Craft Docks & Main Quay Wall. Short Marine Tie Bars assemblies were installed between King Pile Walls. High performance Grade 700, which allow a high level of performance for relatively smaller diameters, was preferred to ease transportation and installation at site.

Petronas RAPID (Refinery And Petrochemical Integrated Development) is a massive petrochemical complex located at the very south of state of Johor, Malaysia, across the sea facing the city-state of Singapore.

The RAPID development, commissioned in 2016, aims to add a 300,000 bbl per day of capacity to the existing local production, making it a strategic development for the Malaysian peninsula.

For this project, Dextra has supplied its Bartec system for the construction of the precast piperacks accross the the project. 30,000 Bartec Headed Bars were used to create horizontal anchoring points for piperacks beams.

The project was supported by a Bartec machine, installed directly at site and commissioned by the Dextra team.

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

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

The assemblies were fixed onto the pilons by the use of gusset plates connected to the forks. Turnbuckles were used for the splicing in the lower part of the assembly, to ease installation. Turnbuckles allow some length adjustment and stressing of the assembly by bringing closer 2 segments of bars.
