The structure, built after completion of engineering, procurement, fabrication and commissioning, was placed on the 7,000-ton Mahdis 1 barge in a ceremony attended by Arsalan Zare, the Bushehr governor general.

The steel structure stands more than 76 meters tall and weighs 2,257 tons. It will be transported to Phase 11 of South Pars, located on the Iran-Qatar maritime border, for offshore installation.

Once fully installed with its wellhead jacket and related equipment, the structure’s weight will reach about 4,100 tons, providing the necessary base for a drilling rig and the start of operations.

For the first time in South Pars offshore development, the jacket was optimized and its weight reduced during design.

The loading and transport operation used heavy-lift equipment and local expertise, marking a key step in the development of the field’s final remaining phase.
