Green Duba Integrated Solar Combined Cycle Power Plant

Green Duba Integrated Solar Combined Cycle Power Plant

Duba ISCC Green Power Plant 1 is a large power infrastructure project taking place in the North West of Saudi Arabia, on the Red Sea. The ISCC (Integretad Solar Combined Cycle) technology is adding 50 MW of solar power to the gas & steam turbine generating 500 MW.

For that project, Dextra supplied Double Corrosion Protection Ground Anchors used as a permanent anchoring solution for the excavation works preparing the pumping chamber. A total of 264 anchors (Grade 1080/1230, Ø32 & 40mm) have been supplied and installed on 4 layers.

The Double Corrosion Protection anchors supplied for this project were pre-grouted at Dextra factory (first layer of grout between steel bar and HDPE sleeve). The pre-grouted segments were reconnected at site thanks to couplers. Pre-grouted anchors not only save time and money on site operations, they also allow an overall better anchor quality by performing the first grout layer in a factory-controlled environment.


Installation at site was carried out by foundation contractor BAUER, which performed drilling, lifting, installation, grouting and post-tensioning operations. Dextra offered guidance during the early steps of the installation by sending a team of geotechnical specialists at site.

The general sequence of installation is the following (illustrated in pictures below):

  1. After unpacking from shipping racks, splicing of segments with couplers, covered by heat shrink sleeves.
  2. Transportation of assembled anchor from assembly to site to lifting area (13kg per linear meter).
  3. Wiring cable at the head of anchor to control the descent. Grouting pipe also pre-installed along the anchor.
  4. Inserting the 30 meters anchor into drilled hole together with grouting pipe.
  5. After grouting and stressing, a head cap filled with grease is installed on the anchor head, maintain the anchor fully isolated from the corrosive outside environment.
