摘要： The invention relates to a method for seismic survey by autonomous seismic nodes (1) at a sea floor (2), comprising: —attaching the seismic nodes (1) to a rope (3); —loading the rope (3) with the seismic nodes into a node deployer (4); —lowering the node deployer (4) into the sea (5); —towing the node deployer (4) above the sea floor (2); —deploying the rope (3) with the seismic nodes (1) at the sea floor (2); —collecting seismic data by the seismic nodes (1); —retrieving the rope (3) with the seismic nodes (1) from the sea floor (2), and —unloading seismic data from the seismic nodes (1). The invention also relates to a node deployer (4) for deploying a rope (3) with seismic nodes (1) at the sea floor (2), comprising a magazine (7) for the rope (3) with the seismic nodes (1).

摘要： Apparatus and methods to operationally link (couple/decouple) a plurality of relatively massive, complimentary payload platforms (i.e., suspended machinery and ROV) at relatively deep working depths in an unstable marine environment (water column) while the payload platforms are in-transit. An apparatus includes a suspended machinery, an ROV, a capture collar, an extendable/retractable harpoon, and actuating machinery to controllably effect extension and retraction thereof. A method includes providing an in-transit suspended machinery having a capture collar, providing an in-transit ROV having an extendable/retractable harpoon, approaching the in-transit suspended machinery with the ROV, maneuvering the ROV so as to bring an end of the partially extended harpoon into aligned proximity with the capture collar, and further extending the harpoon so that it securely engages the capture collar.

摘要： Polymetallic nodules are collected by means of a plurality of self-propelled vehicles which move upwards and downwards between the sea floor and a surface platform under the action of excess ballast which is partially and progressively released as the vehicle approaches the bottom. The vehicles are propelled along the sea floor by means of at least two supporting units each having at least one helical propulsion fin, the remainder of the ballast being released in order to return the vehicles upwards for docking, unloading and energy-recharging in the surface platform.

摘要： A submergible, underwater well completion habitat and a method of employing the same in the completion of wells at extended depths. The well completion habitat may be attached to an underwater well platform and maintained at a pressure of sufficient value to expel water from the work chamber and also to maintain it substantially water free so that one or more saturated divers may work within the chamber to complete the well. This abstract of the invention is neither intended to define the scope of the invention, which, of course, is measured by the claims, nor is it intended to limit the invention in any way.

摘要： Diving apparatus which includes a bell assembly normally negatively buoyant and including a bell. There are frame means movable vertically beneath the sea surface. Such frame means are movable between an upper position and a lower position above the subsea surface and at which the frame means can be made temporarily stationary. Bell moving means are connected between the bell assembly and the frame means for moving the bell between a lower position adjacent the subsea surface and an upper position adjacent the frame means.

摘要： A transit capsule for providing operator access to a sub-sea installation part in a capsule on a sea-bed, the two capsules having complementary means to form a conjunction capsule, has means selectively connecting an expansion vessel in the transit capsule to the other two capsules; on connecting the said other two capsules which are water-filled, their pressures are reduced to the atmospheric pressure in the transit capsule with only a small amount of water being ejected to balance the pressure and this small amount can be inspected to determine the state of the said other two capsules by suitable inspection means.

摘要： A clamp engages an object such as a pipe at an undersea location and the clamp is connected by a wire to a surface station. At the upper end of the clamp is a mechanism for operating the clamp and this mechanism is provided with a seat for receiving a clamp arm of a manned submergible chamber. The manned submergible chamber grips the clamp mechanism and working in conjunction with the surface station closes the clamp on the pipe, and then after disengaging the work arm, the clamped pipe is brought to the surface station. The mechanism of this invention is particularly suited to offshore drilling operations as well as salvage operations. In another embodiment a hook is guided by the work arm to an object such as a pad eye and the hook engages the pad eye by the movement of the work arm. Once the pad eye is hooked the wire takes the hooked object to the surface.
