FIELD: transport.
SUBSTANCE: invention relates to ship building, particularly, to vessels intended for underwater operations. Claimed two-platform complex comprises ice-going vessel and processing equipment for inspection, construction and repair of sea structures with module for underwater docking and welding of underwater pipelines at oil and gas deposits. This complex comprise another ice-going vessel. The latter features ice breaking hull to operate in working area with underwater docking and welding module arranged thereat.
EFFECT: higher efficiency of underwater operation in ice condition of shallow water area.
