Seakeeper’s Super Spinning System Keeps Ships Stable at Sea

This application is a continuation-in-part of application Ser. This invention relates to cargo vessels, and more particularly to cargo vessels having holds which are utilizable both for dry bulk cargoes and general cargoes. The holds of cargo vessels have been designed to haul either bulk cargoes when the hold is free from obstructions, or for general cargoes in holds provided with tween decks to support multiple tiers of cargo, such as palletized cargo or containers of cargo.

Also, some vessels have been adapted for mixed cargoes by providing a conventional tween decks in the upper portion of the hold with the lower portion being left unobstructed for the hauling of dry bulk cargo. However, need exists for a cargo vessel that can be rapidly converted from the handling of dry bulk cargo to the handling of general cargo by the use of mechanisms contained aboard the vessel.

When converted for the hauling of dry bulk cargo, it is desirable that the hold be substantially free of structural supports and other obstructions. Also, it is desirable that the tween deck structure utilized for the storage of general cargo be adjustable so that the height between the tween deck structures can be changed to accommodate various types and sizes of cargo and cargo containers, and that this structure be able to accommodate pallets of the maximum size and weight that can be loaded outside of the vessel and then placed aboard so as to provide high cargo handling efficiency.

Accordingly, a principal object of this invention is to provide a cargo vessel having cargo holds optionally convertible for the handling of dry bulk cargo or general cargo.

Another object of this invention is to provide a cargo handling system for cargo vessels that provides high handling efficiency for general cargo and that can be readily converted to provide an unobstructed hold for the transport of dry bulk cargo.

Still another object of this invention is to provide a tween decks structure for a ship's hold that is adapted for the storage of general cargo of various types and sizes, and which is readily manipulated to convert the cargo hold for the transport of dry bulk cargo. A further object of the invention is to provide a cargo handling system for a cargo vessel that permits efficient handling of general cargo on omnipallets of maximum size and weight, and that is readily converted for the transport of dry bulk cargo.

A yet further object of the invention is to provide a cargo handling mechanism for the efficient handling of general cargo on omnipallets of maximum size and weight and that can be readily converted to provide a substantially unobstructed hold for the transport of dry bulk cargo, and in which all of the component parts of the mechanism are contained aboard the vessel.

Briefly, this invention contemplates a shifting tween deck structure for the hold of a cargo vessel that includes a plurality of parallel beams movably supported between pairs of rails adjustably secured at the sides of the cargo hold. The beams span the hold and are individually movable on the rails to a central position below a cargo hatch to receive omnipallets of cargo which are supported in the hold between adjacent beams.

At least some of the omnipallets are movable on the beams, and the loaded pairs of beams are shiftable to the side of the hold. The unloaded beams are optionally shiftable to the sides of the cargo hold to convert the hold for dry bulk cargo, or the beams can be removed and stowed on deck. The two rails comprising each pair of rails are located at the same vertical level at opposite sides of the hold.

The rails can be located at the sides of the hold or at the transverse bulkheads. New vessels can be designed with holds with a vertical framework frames, web-frames and bulkhead stiffeners to which the rails are attached to support or vertically slide the tween decks. Vessels already in service are provided with horizontal rails attached to the hold framework at either the sides or bulkheads. The system can be incorporated into ship's longitudinal framing, at convenient vertical spacing, or vertical slide rails, or supports fixed on each longitudinal frame can be provided to adjust the vertical spacing between the horizontal rails.

The tween decks are formed by beams or girders having wheels or rollers and, therefore, being ready to roll or slide on the horizontal rails. Preferably, the wheels operate between an upper and a lower rail which avoids the possibility of derailing in heavy seas, or on one rail with a device to prevent derailing. Where the rails are located adjacent to the transverse bulkheads and extend transversely of the vessel, the beams extend longitudinally of the vessel and move from side to side, i.

Where the pairs of rails are placed longitudinally of the vessel, the beams extend across the beam of the vessel and are shifted in a direction lengthwise of the vessel. The beams are vertically spaced to permit rows of boxes, bales, cars, pallets, containers, or goods between each two tween decks.

These vertical spacings can be arranged to suit the cargo either by sliding and fixing the rails at the desired locations, or by bolting the rails at the desired locations. The beams form an open rack tween deck structure which supports a plurality of large pallets called "omnipallets. Each omnipallet consists of a frame adapted to support the cargo, and is provided with at least four wheels or rollers, two being located on each side, and also with fittings for cleats to secure the cargo and with four lift rings which allow the omnipallet to be lifted by a crane or cargo winch.

The size of the omnipallets is limited by the size of the hatch opening and the maximum weight the cargo handling machinery can lift. This makes the omnipallets stowable at high speed. If the cargo is known, each tween deck is vertically spaced according to the height of the cargo. The horizontal separation between two adjacent beams which support the omnipallets and form the tween deck structure is achieved by shifting the beams on the rails by means of any mechanical, hydraulic, or pneumatic mechanism, such as rod or link mechanisms or telescopic cylinders.

These beams may also be placed in their cargo position with the separation being maintained by cables. When the hold is to be converted for the transportation of bulk cargoes, then using any one of these mechanisms, the beams are moved to the sides of the ship, or the bulkheads, as the case may be, and stowed side by side. Optionally, the beams can also be hung under the upper deck, thus leaving the hold unobstructed. This latter system of stowage is used when the beams are vertically adjustable and can be raised to the top of the hold, or can be bolted at different heights.

The system operates at maximum efficiency when each lift has the maximum volume for the hatchway or the maximum weight for the cranes. The omnipallets are placed on the quay and loaded with boxes, bales, cars, or other cargo, which is duly lashed or cleated into place. A pair of the beams are provided with the proper separation and shifted under the hatch.

The omnipallets are placed upon the beams and shifted to the proper location. When a pair of beams is loaded with the maximum number of omnipallets, the next pair of beams are shifted into place and loaded. The various tiers are loaded from the bottom up, unless an opening is left to move more omnipallets vertically in the hold.

The first cargo of omnipallets received is stowed on the bottom tank top, and cleated down. The lowest tween deck beams are then uncleated and rolled on the side tracks until they are adequately spaced to receive the omnipallets. The first pallets with their cargo are secured to them, and loading is carried out covering the space between an end beam and a central beam. The loaded beams are shifted into the storage position. Next, the same operation is carried out in the space formed by the other end beam and the second central beam.

This second pair of loaded beams is then shifted into the storage position. Lastly, the space between the central beams is loaded with more omnipallets. As each omnipallet is placed on the tween deck, it should be fixed or cleated into position. The same process is followed to load the rest of the tween decks.

Preferably sufficient omnipallets are loaded onto the beams to completely cover each tier. The transport of mixed cargo is also possible. For instance, containers and general cargo can be transported in the lower part of the hold and cars on the higher tween decks.

Also, dry bulk cargo can be transported in the lower part of the hold and general cargo in the upper tween decks. When the hold is unloaded of a general cargo and is prepared for a bulk cargo, the tween deck beams are rolled to each side of the hold, or to the end bulkheads, or they may be removed for storage on the upper weather deck, so as to stow the beams in a location where they do not obstruct the hold.

For instance, in the case of light grain cargoes, it is not necessary that the beams be stowed apart. However, the omnipallets are first removed from the hold and stowed on the upper weather deck.

It can be clearly appreciated that the main features of this loading system are: 1 the use of omnipallets for a maximum cargo lift taking into consideration the dimensions of the hatch opening; 2 that the tween decks are comprised of an open structure; 3 that the tween decks structure shifts sideways or endwise so as to leave the hold substantially unobstructed; 4 that at least some of the omnipallets can be shifted on the tween decks; and 5 that the omnipallets can be stowed on top of each other on the upper deck, in the same manner in which the pontoon-type hatch covers are stowed when the ship is in port.

The tween deck structure of this invention and its method of operation will be more readily understood by reference to the following description and the accompanying drawings, wherein like numerals refer to like parts throughout, and in which:.

Referring now to the drawings, the numeral 1 represents a ship's hull such as the hull of a cargo vessel, provided in conventional manner with a double bottom 2, a hatch opening 3 through which cargo is loaded and unloaded, upper ballast tanks 4, and watertight transverse corrugated bulkheads 14 dividing the hull into a plurality of cargo holds.

In the embodiment illustrated in FIGS. The beams 5, 6, 7 and 8 of each tween deck structure are movably supported on a pair of transverse rails 10 secured at the same vertical level at opposite ends of the cargo hold to form a track upon which the beams move. In the illustrated embodiment, each tween deck is comprised of four movable beams excepting for the top tier which is comprised of only two beams 11 and However, it is to be recognized that the tween decks can be formed of any number of beams as required to provide support for the desired number of rows of omnipallets.

In FIG. In this manner, the tween decks can be shifted to positions at the sides of the hold to convert the hold for bulk cargo storage, with the entire cargo hold being substantially unobstructed. With the hold thus converted for the transport of dry bulk cargoes, the omnipallets can be conveniently stored on the weatherdeck in positions 28 illustrated in FIG.

In the embodiment of the invention illustrated in FIG. In this embodiment, rails 34 are positioned adjacent to the sides of the hold and extend longitudinally of the hold. The beams 30, 31, 32 and 33 are positioned across the beam of the vessel so as to span the hold. The beams are movable on the rails in a longitudinal direction, i.

The omnipallets loaded with cargo 35 are placed between adjacent beams such as the pairs of beams 30 and 31, and 32 and Omnipallets are also placed in the central section between beams 31 and The construction of the tween deck and the method of supporting the omnipallets between adjacent beams is illustrated in FIG.

The illustrated portion of the tween deck includes outside beam 40, provided with track 41 and interior beam 42 provided with a pair of tracks 43 and Omnipallet 45 is provided with a pair of wheels on each side, such as the wheels 46 and Omnipallet 45 is movable along the beams and the beams 40 and 42 are movable in a direction normal to their length, limited only by the vertical member 48 which represents a vertical frame member either at the side of the hold or adjacent to the transverse bulkhead.

The beams 40 and 42 can extend longitudinally of the vessel or transversely across the hold as hereinabove more particularly described. Each adjacent pair of movable beams, such as the beams 40 and 42, are provided with means to provide the spacing required to receive the omnipallet. In the embodiment illustrated in FIG. The rods 60 and 61 fold in the horizontal plane so that the beams may be moved into a juxtapositioned relationship, but which limit the separation between the beams.

Thus, the beams are individually movable up to the limit of travel provided by the spacing rods. Beam 50 represents any one of the movable beams forming the tween deck structure, and is provided with a wheel unit at each end, such as the wheel carriage 51 provided with a pair of wheels 52 and Carriage 51 supporting beam 50 travels on horizontal rail 54 provided with track The horizontal rails which support the movable beams are preferably vertically adjustable so that the spacing between the various tween decks can be adjusted to efficiently accommodate cargoes of different heights, thereby permitting maximum utilization of the cargo space.

Although various adjusting mechanisms can be employed, such as ratchet and pawl drives, hydraulic jacks, and the like, it is convenient in many installations to provide means for bolting the beams to the vertical support members at different vertically spaced positions. A pair of spacers 71 and 72 are welded or otherwise secured to member 70, and the beam is provided with a plate 74 which abutts spacer The beam is removably secured to spacer 71 by the bolts 75 and It is apparent that the beams can be readily moved to any one of a plurality of the spacers to adjust the height of the tween decks.

To facilitate rapid loading of the vessel, the cargo, such as a mixed general cargo or cars, is loaded on omnipallets placed on the quay, then duly secured to the omnipallets and left until the vessel is ready for loading. To load the omnipallets onto the vessel, an outer beam and a central beam, such as the beams 5 and 6, are shifted toward the center of the vessel so as to be positioned below hatch 3 and spaced the proper distance apart to receive the omnipallets.

With the cargo jib, aft starboard omnipallet 20 is placed inside the hold and positioned so that it is supported between beams 5 and 6. Omnipallet 20 is then moved toward the aft end of the beams adjacent to the aft bulkhead Then fore starboard omnipallet 23 is placed in the hold on the beams 5 and 6 and moved toward the forward end of the beam adjacent to forward bulkhead Central starboard omnipallets 21 and 22 are placed on the beams 5 and 6 and the entire structure consisting of the beams 5 and 6 and omnipallets 20, 21, 22 and 23 is shifted into the storage position at the starboard side of the hold.

The same procedure is carried out in loading aft port omnipallet 16, fore port omnipallet 19, and central port omnipallets 17 and 18 onto beams 7 and 8. This entire assembly consisting of beams 7 and 8 and omnipallets 16, 17, 18 and 19 is shifted into the storage position at the port side of the vessel.

The sun has burned through the early morning marine layer, and the breeze is gentle and warm enough for me to abandon my hoodie. It looks like a perfect day to head out onto the Pacific Ocean. But as soon as we exit the harbor walls at Marina Del Rey, near Los Angeles, the foot sport-fishing boat starts to heave.

This is where the spacecraft's pilot flies the ship. In fiction it is often the dramatic focus, even though without help from the astrogator, engineer, and ship's captain one will find that the pilot is helpless.
