Project Yamal LNG
Purpose SPMT maintenance workshop
Climate Polar
Location Sabetta, Yamal Peninsula Tengiz

Wide span space customized for SPMTs

Yamal LNG commissioned Mammoet to provide a transportation network for their Sabetta Seaport development.

The customer required the hydrocarbon mixture produced from the wells to be sent to the integrated treatment and liquefaction plant prior to further distribution. Production of this size needed non-conventional trailers to assist with operations. Specializing in oversized equipment transportation, Mammoet provided Scheuerle SPMT and Goldhofer self-propelled mounting trolleys. Self-propelled trailers carry loads up to 36 metric tons per axle line.

The Yamal Peninsula (Russia) lays in 24-hour daily darkness throughout most of the winter. It is one of the most northern settlements in the world, and the climatic conditions are quite severe. The temperature often drops to as low as -57ºC.

As part of its service, Mammoet provides ongoing maintenance and repair of the equipment for the lifetime of the project. To meet the HSE regulations for protection of the staff, as well as the material, Mammoet needed an enclosed clear span space for the parking, maintenance, and repair of the self-propelled mounting trolleys.


The severe nature of the climatic conditions in this region makes it almost uninhabitable for humans. The ‘Nenetler’ indigenous tribe of this northernmost tip of the world called this region Sabetta, meaning ‘The End of the World’ because the region is shrouded in darkness for much of the year and temperatures frequently falling to -57ºC.

Having to base out of the port, this made obtaining a building permit impossible due to the governing bodies security regulations. HSE regulations are also highly regulated to ensure that all the staff working in the region is protected and kept safe.

Considering all the above, the inflatable hangar looked to be the most feasible choice over permanent construction for a time-limited project.

Delivered materials and accessories

Aviatech produced three (3) hangars, each with dimensions 20 meters wide and 70 meters long (1400 m²). From conception to availability, Aviatech delivered the structures ahead of schedule in under 80 days.

The Aviatech team organized expedited delivery through standard ground transportation. Each hangar set included LED lighting system (200 LUX), autonomous power back-up systems and diesel-powered heating system to withstand the below freezing temperatures.

Results and execution

The temporary nature of the inflatable hangars granted Mammoet access to the Sabetta Sea Port with their own facilities, as no construction permits were required. It allowed Mammoet to maintain the equipment in warm facilities much more efficiently. Thus, making inflatable hangars one of the vital components of the project.

Upon delivery of the hangars, the Aviatech supervisors held an in-depth training session for 17 of the Mammoet staff. The course included theoretical preparation, deployment and operations training.
