Onshore and offshore pipeline welding company, Serimax (a Vallourec subsidiary) has successfully completed its welding scope for the Trans Anatolian natural gas pipeline (TANAP) project.

For this particularly ambitious project, Serimax deployed 15 stations equipped with a high-tech automated welding solution called Saturnax 05; an orbital welding equipment for pipeline applications. The company also used four Maxiluc re-rounder clamps that facilitate and accelerate spacing, thus optimising welding cycle time to manage steep slopes of up to 25° in remote areas.

The initial challenge during this TANAP project was ensuring that all of the necessary equipment was mobilised and ready to begin onsite qualifications over a tight four week time frame. The following welding of large diameter pipes (56 in.) with large thicknesses (19.5 - 30 mm) took place in a particularly demanding environment, crossing mountains up to a height of 2500 m and facing harsh climatic conditions, such as severe cold of down to -25°C.

Serimax’s expertise, rigorous project management procedures and the extreme reliability of the equipment used assured a quality service. The company successfully welded 25 700 56 in. welds, resulting in approximately 420 km of pipeline in total.

TANAP will transport gas from Azerbaijan's Shah Deniz field (Caspian Sea) to Europe via Turkey. The main pipeline, which travels from east to west through Turkey, extends for a total of 1850 km, with 19 km running under the Sea of Marmara.
