Abstract

Способ добычи отложений с морского дна с использованием надводного плавсредства (20), не привязанного к морскому дну, и первого и второго всасывающих самоходных агрегатов (27; 30), которые перемещаются по морскому дну для всасывания отложений и каждый из которых соединен с надводным плавсредством соответствующим гибким райзером (26; 29), по которому суспензия из отложений передается с всасывающих самоходных агрегатов на надводное плавсредство. Способ содержит перемещение первого и второго всасывающих самоходных агрегатов взад и вперед по морскому дну в множестве полос движения так, что агрегаты перемещаются, значительно удаляясь от надводного плавсредства, с выполнением поворота или смены направления движения на обратное каждым агрегатом в конце каждой полосы движения таким способом, что полосы движения располагаются смежно друг с другом для разработки отложений, по существу, без промежутков между смежными полосами движения. Только всасывающие самоходные агрегаты опираются на морское дно.A method of extracting sediments from the seabed using a surface floating craft (20), not tied to the seabed, and the first and second self-propelled suction units (27; 30), which move along the seabed to suck up sediments and each of which is connected to the surface watercraft corresponding flexible riser (26; 29), through which the suspension from the sediments is transferred from the self-propelled suction units to the surface floating craft. The method comprises moving the first and second self-propelled suction units back and forth along the seabed in a plurality of lanes so that the units move, significantly away from the surface craft, with each unit turning or changing the direction of movement to the opposite at the end of each lane in this way, that the lanes are located adjacent to each other to develop sediment, essentially without gaps between adjacent lanes. Only self-propelled suction units rest on the seabed.
