Abstract:
A mobile docking apparatus (100) is disclosed, which comprises a platform (102) arranged to receive at least one floating/transportable object; and a plurality of supporting legs (104) movably coupled to the platform and configurable to be lowered to the seabed to anchor and/or support the apparatus, wherein the platform is operable cooperatively with the lowered supporting legs to be adaptively raised or lowered with reference to a water-level to receive and lift the object. A method of operating the apparatus is also disclosed.
Abstract:
La présente invention concerne les systèmes de mise à l'eau et de récupération d'embarcations sous-marines depuis un navire. Elle consiste principalement en une nacelle de manutention (10) pour la mise à l'eau et la récupération d'un véhicule sous-marin (20), comportant un châssis (11) formant une arête dorsale et réalisant une interface entre des moyens de levage, une grue par exemple, et le véhicule sous-marin. Ce châssis comporte : des moyens (12) pour ajuster la flottabilité d'ensemble; des moyens (13) pour assurer un alignement automatique du véhicule sur l'arête dorsale constituée par le châssis; des moyens (14) pour opérer depuis la surface la préhension du véhicule après alignement du châssis sur le véhicule. Dans un mode de réalisation préféré la nacelle comporte une caméra vidéo embarquée permettant à l'opérateur situé à bord de s'assurer de la bonne réalisation des opérations d'arrimage et de libération du véhicule. L'invention permet avantageusement de procéder de manière automatique à la mise à l'eau et à la récupération du véhicule alors que celui- ci est sous la surface dans une zone où il ne subit pas les effets de la houle.
Abstract:
A method and apparatus for launching and recovering an object by a host vessel while the host vessel is in motion. The recovery system utilizes a tethered capture system for connecting with the object and then directing the object to the host vessel where it is secured. The tethered capture system includes one or more side planers that direct a capture cable away from the host vessel. The capture cable is preferably disposed below the waterline through the use of a diving rig or extended cable struts so that the cable does not foul the propeller of the object to be recovered. The side planer itself may include a ramped surface for loading the object prior to securing to the host vessel. After the capture, the object may be secured by way of a boom attached to the host vessel or by a lifting cradle that selectively extends aft of the host vessel.
Abstract:
A stowage system for stowing a smaller boat on board a larger parent boat is provided. A well sized to receive the smaller boat is formed below the aft cockpit deck of the parent boat adjacent the stern. A movable cover assembly in the nature of a hatch(s) covers the well and sits flush at deck level when in a closed position. The cover assembly is movable to expose the well so that the smaller boat can pass through the opening when the cover is in an open position. Also, a skeg assembly with twin skegs provides an improved tracking capability for a powerboat and provides sufficient space for the small boat stowage system. The twin skegs, which provide support for inboard engine shafts, are symmetrically located on opposite sides of a centerline of the hull near the stern. Water flow tunnels between the skegs.
Abstract:
A barge-carrying vessel (1) comprises an afterpart (2),a forepart (3), and a beam system (4) connecting said afterpart to said forepart, said beam system having fastening means (14) for barges (B), connectible to said beam system and said fore- and afterparts, such that the outwardly facing shell plating portions of the barges substantially coincide with the adjacent shell plating portions (8) of the vessel. The novel matter of the invention resides in that said beam system (4) incorporates a beam (5) of lattice construction, one end of said beam being supported substantially stationary by supporting means (7) on the afterpart (2), and in that the forepart (3) has beam supporting means (9) adapted to permit relative displacement such that said fore- and afterparts (3, 2) can be moved towards and away from one another. If required, barges (C) can be loaded on top of said beam (5) via ramps (36) and sliding members (34) at the deepest trimmed beam end (at the forepart).
Abstract:
A system for conveying a fluid produced from at least one producing subsea well to an existing host facility via a flowline includes a support structure having at least a deck, a mooring system, and a plurality of topsides modules. The mooring system anchors the support structure to a seabed and passively positions the support structure proximate to the at least one producing subsea well. The support structure elevates the deck above a water's surface and is normally unmanned. The plurality of topsides modules are disposed on the deck. The topsides modules include at least: a power generation module; a switchgear module a flowline heating module; a chemical injection module; a water injection module; a subsea control module; and a control module that communicates with a remote command center.
Abstract:
An apparatus for launching, stowing and retrieving of daughter boats (1) from a midships hangar or mission bay on a mother vessel comprises at least one davit assembly positioned atop a stationary cradle (2), located one each near the starboard and port of the mother vessel. The daughter boats (1) are secured on specially designed stationary cradlesalong a plurality of longitudinal tracks (5) and also on at least the two stationary cradles (2) one each near the starboard and port of the mother vessel which are also specially designed and lie along at least one transverse track (6).
Abstract:
The present invention provides a remote-controllable underwater device for manoeuvring a vessel. The device comprising at least one housing, a connection unit provided on the housing for rigidly attaching below the water to the vessel to be manoeuvred, at least one propeller mounted on the housing for moving the device and the vessel attached to the connection unit, an antenna for communication with the device from a remote control unit, at least one sensor for path tracking and positioning of the device and the vessel, and a power source for providing power to the connection unit, the propeller, the antenna, and the sensor.
