摘要:
A system and method for stockpiling material on the seafloor, the system and method using seafloor collection machines, such auxiliary or bulk cutters or collection machines, to capture seafloor material to be stockpiled. The captured seafloor material is carried in slurry form over a flexible transfer pipe to an outlet at a desired seafloor site. In a preferred form the outlet is mounted in a seafloor stockpiling hood that sits on the seafloor at the desired seafloor site and captures and contains slurry from the outlet while allowing egress of water. The captured seafloor material can then be extracted to a surface vessel.

A seafloor nodule concentrating system is disclosed. The seafloor nodule concentrating system has a surface vessel and an undersea steering vehicle secured to the surface vessel. The undersea steering vehicle is adapted to be towed by the surface vessel. The seafloor nodule concentrating system also has a nodule collecting apparatus connected to the undersea steering vehicle. The nodule collecting apparatus is located on the seafloor. The seafloor nodule concentrating system also has a position determination device adapted to determine the position of the nodule collecting apparatus and communicate position information of the nodule collecting apparatus to the undersea steering vehicle and surface vessel.

The invention relates to a vessel comprising a barge loading system (10) for loading a secondary vessel positioned alongside the vessel (1) with a mixture of water and material, comprising a discharge pipe (11) and a discharge head (12). The barge loading system (10) comprising at least two moveable crane arms (20) connected to the discharge head (12). The crane arms (20) being arranged to move the discharge head (12) to an overboard position. The crane arms (20) comprise respective base arm portions (21) rotatably connected to a deck (2) of the vessel (1) and respective remote arm portions (22). The remote arm portions (22) are with one end rotatably connected to respective base arm portions (21) and with another end connected to the discharge head (12). The barge loading system (10) comprises cable systems arranged to move the base arm portions (21) and the remote arm portions (22).
摘要:
The invention relates to a riser system for transporting slurry from a sea bed (4). The riser system comprising a vertical riser pipe (10) and at least one pump (30) provided along the riser pipe (10). The riser pipe (10) comprises a pipe input opening (12). The riser system comprises a frame (40) to which the pump (30) is mounted. The frame (40) comprising a first connection member (41) at a predetermined distance from a pump output opening (32). The riser system comprising a second connection member (15) provided along the riser pipe (10) at the predetermined distance above the pipe input opening (12). The first and second connection member (41, 15) being rotatably connectable allowing the frame (40) to rotate under the influence of gravity to a hanging position in which the pump output opening (32) connects to the pipe input opening (12).

摘要:
The invention relates to a method and a device (1) for dumping dredged material and the like on a bottom (11) present under the water surface (3). The dredged materials or the like are delivered under the water surface by means of a conveyor pipeline (9) comprising a portion extending in the direction of the bottom under said water surface. The part (9, 10) of the conveyor pipeline (9) extending under the water surface is at least partly surrounded by a screen (6) which extends to near the bottom (11). The screen is attached to a floating body (2). Means (7) by which the bottom end of the screen (6) is adjustable for height with respect to the floating body (2) are connected to the bottom end of the screen.
摘要:
A conveyor system for a two-phase flow, such as water containing sand, gravel and the like, comprising at least one conveyor pipeline (1) with means (2) for generating a flow, characterized in that the internal surface of the conveyor line bears guide means (7) for influencing the flow. A pump (2) is accommodated in the conveyor pipeline, and the guide means (7) are situated immediately upstream of the inlet of the pump. In case the pump is a rotary pump, the guide means are designed to impart a preliminary rotation to the flow.
摘要:
Das von einem Schwimmbagger 1 mit Schwimmgreifer 2 geförderte Sand- und Kiesmaterial wird einer Aufbereitungsanlage 3 zugeführt. Die hierbei anfallenden mineralischen Feinststoffe werden über eine schwimmend verlegte Rohrleitung 4 und ein daran angeordnetes schwenkbares Rohr 11 einem Unterwasserdiffusor 5 zugeführt, der das Material zur Abdichtung auf dem Seeboden 12 bzw. der Böschung 13 aufbringt. Der Diffusor 5 ist an einer Schwimmstation 6 angeordnet.
摘要:
Es ist ein Gerät mit mehreren Schwimmkörpern (2) vorhanden, die eine zylindrische odertonnenförmige Grundform aufweisen und bei denen das eine Ende einen Kugelkopf (4) und das andere Ende eine Kugelpfanne (5) bildet, wobei die Schwimmkörper mit kugelgelenkartig ineinandergreifenden Enden durch Seile (1) verbindbar sind, die durch axiale Öffnungen (6) der Schwimmkörper (2) geführt sind. Zwecks Schaffung eines Gerätes, das sich für die verschiedensten Anwendungsfälle, insbesondere als Hochseeölsperre und für den Massengütertransport, eignet, wobei übermäßige Seilbeanspruchungen vermieden werden, sind die Schwimmkörper (2) jeweils zu einzelnen, eine Schlange bildenden Reihen verbindbar und ihre dem Durchzug des Seiles dienenden axialen Öffnungen (6) weisen im Kugelkopf (4) bzw. der Pfanne (5) trichterartige Erweiterungen (7,8) auf, so daß die Spannlänge des Seiles bei jeder Abwinkelung aufeinanderfolgender Schwimmkörper (2) gegeneinander im wesentlichen konstant bleibt.
