FIELD: offshore working of mineral deposits. SUBSTANCE: lifting means with platform on its lower end is suspended from floating craft. Platform is connected with towed mining outfit. The latter is made up of excavation modules. Each module comprises a working member with protective screen. Working member is connected by pulp conduit with common horizontal pulp duct. Platform is connected with horizontal pulp duct by flexible pulp conduit and winches. Front ends of skids of excavating module are disposed above its pulp duct. Winch ropes are connected with horizontal pulp duct via blocks secured thereon. Horizontal pulp duct carries depth rudders. The relief of sea bed is determined by moving excavating modules. To negotiate an obstacle, the production outfit is lifted above by winches. EFFECT: improved design.
