Cutting-edge fleet

The unique pipe-laying barges "MRTS Defender" and "Captain Bulganin" are giant floating platforms equipped with specialized workshops for the production and laying of pipelines, capable of withstanding harsh environmental conditions. On these barges, pipeline sections are continuously welded together and hydro-insulated. They also undergo other necessary calibration work, after which the pipes are laid on the seabed using a stinger.


The unique and unrivalled (not only in Russia) maritime fleet of MRTS JSC has long been a source of special pride for the company.

More than 30 multifunctional vessels comprise our fleet:

  • Pipe-laying barges
  • Ice-class vessels

  • Pipe-laying cranes with a lifting capacity of 90 tons
  • Floating excavators of the Water Master type
  • Tracked cranes with a lifting capacity of up to 550 tons
  • Bulldozers
