Abstract
ABSTRACT
A cargo carrying vessel which is provided with an elongated bulbous pressure hull designed to operate in a semi-submerged state. The vessel is provided with one or more rigid wing sails to aid propulsion and solar cell arrays are mounted on each wing sail to generate electrical energy. The electrical energy is used to power an electric motor which drives the vessel in conventional manner. Excess energy may be stored in banks of storage batteries which form part of the internal ballasting of the vessel.

Description
This invention relates to a semi-submerged cargo vessel and more particularly a sail-assisted semi submerged cargo vessel.
Submerged and semi-submerged sea going vessels which are capable of carrying cargo are relatively well known in the art. Many submarines have been developed over the ages using various forms of motive power including diesel and gasoline engines and more recently electric and nuclear engines. Because these vessels are designed to withstand considerable water pressures, special technique~ and equip-ment for operation are required. Semi-submerged vessels, and -in particular flexible bulk gas and oil carriers, have also been designed generally for towing astern of conventional surface vessels.
; Rigid wing sails are also known to the art for ;propulsion of relatively light sport-sail boats (see, for example, U. S. Patent 2,487,687) but, as far as is known, it has not been suggested that a semi-submerged cargo carrying vessel ~hould be provided with wing sails to aid the propulsion thereof.
Solar cells for the production of electrical energy are also known to the art, see, for example, U. S.
Patent 3,410,0B6, particularly in space craft where they are generally deployed on rigid wing-like structures to achieve maximum solar exposure. It has not, however, been suggested that solar cells may be incorporated into wing sails for ship propulsion.
It is an object, therefore, of the present invention to provide a novel semi-submersible cargo carrying vessel which is provided with wing sails to assist propulsion and wherein the rigid wing sails incorporate solar cell - 1 - ~ :
'~:
, :: ~049856 arrays to generate power which is used for additional propulsion needs either directly to an electric tor or via storage batteries.
Thus, by one aspect of this invention there is provided a cargo carrying vessel comprising (a) a hull adapted to float with a ma~or proportion thereof beneath the surface of an aqueous medium; (b) at least one substantially rigld wing sail member plvotally mounted on said hull; (c) solar cell means disposed on said sail member for generating electrical energy; (d) motor means, powered by said electrical energy; and (e) drive means operatively connected to said motor means for propelling said vessel through said aqueous medium.
The invention will be described in more detail hereinafter with reference to the drawings in which:
Fig. 1 is a side elevation of one embodiment of the ssil ship of the present invention;
Fig. 2 is a plan view of the shlp of Fi8. 1;
Pig. 3 i8 a front vlew of the ship of Fig. l; and Fig. 4 is a sectional vlew of an alternative embodiment of the present lnvention, showing an internal ballasting arrangement, resulting in a slightly modified hull shape.
In Fig. 1, there is shown an elongated, bulbous semi-submersible hull 1 designed to float in a substantially submerged position in an aqueous medium, such as sea water, using external (Fig. 3), internal (Fig. 4) ballasting and trim tanks to maintain the centre of gravity at the desired level. The hull is substantially completely enclosed and is designed to withstand considerable pressure, in the manner of a conventional submarine. The superstructure 2 is relatively small compared to the hull, in the manner of a conventional conning-tower of a submarine, and is relatively narrow and high. The sides 3, 4 of the superstructure are inwardly curved in order to tisperse the force of crashing waves. The deck 5 is narrow and relatively high above the water line, thereby avoiding breaking seas in all but the heaviest weather.

- . .
In the embodiments shown, the ship i6 provided with four rigid steel telescopic masts 6, 7, 8 and g, each carrying three substantially rigid wing sails 10, 11, 12, known per se, the upper - sections being de~igned to telescopically retract into the lower section.
The number of masts and sails is not, of course, critical but merely a matter of convenience.
It will be appreciated that sail 12 retracts into ~ail 11 and said 11 retracts into sail 10. In very heavy seas with the sail area reduced by retraction of the upper sections and by moving the wing -sails into a neutral position relative to the ambient wind, the vegsel is practically enabled to lie ahull. The lateral thrust of the masts 6, 7, 8 and 9 and sails 10, 11 and 12 is balanced by a relatively deep ballasted keel 13 (Figs. 1, 2 and 3) or by internal ballasting and a modlfied internal keel form 14 (Fig. 4). Bilge keels lS and a skeg 16 may also be provided, depending upon the particular design characteris-tics required.
The masts, which are preferred but not essential to the invention as the rigid wing 6ails may be mounted in alternative ways, and sails are pivotally unted through the superstructure 2 80 that the sails 10, 11, 12 may be trimmed in conventional manner to provide forward propulsion of the vessel. The 6ails 10, 11 and 12 are also provided with arrays of solar panels 25 which generate electrical power, in a manner known per se, at least during daylight hours when the sun i8 shining.
Power generated thereby is used by an electric motor 26 which drives a - variable-pitch double propeller 17. Any excess power generated may be ;~
stored in storage batteries 18, which form part of the solid internal ballast of the ve~sel, for 6ubsequent use for propulsion or general utility aboard the vessel. It will be appreciated that, for safety considerations, a conventional diesel or similar engine may be installed for emergency propulsion.
As will be seen most clearly in Pig. 4, the bulbous nature of the hull 1 makes docking at a conventional dock relatively difficult and 1~)4985~
recourse i8 best made to the use of a retractable ~etty 19 for access to the top deck 5, or to hydraulic self-docking devices and gangways.
Retractable port holes 20, 21 may be provided in sloping walls 3 and 4 of the superstructure to facilitate cargo handling to the lower decks and holds of the vessel. An elevator 22 may algo be provided for cargo and personnel carrylng as required.
The vessel i8 designed for movement through ~he water ln the semi-submerged position as shown in Fig. 1 and clearly when in ballast will tend to ride high in the water. This tendency may be eliminated by flooding the flood tanks 23, which are located around the hold 24 and form part of the internal ballasting of the vessel.
The vessel of the present lnventlon may, of course, be modlfled in many ways without departing from the scope of the invention, the purpose of which is to provide a structurally safe and smooth mode of transportation and to provide an environmentally acceptable solution to the problem of heavy cargo handling, substantially without the use of expensive fossll fuels.
The present vessel may best be descrlbed as a sail assisted electro-ship which utilizes both wind and solar energy to provide its tive power. It is to be stressed, however, that the vessel of the present invention iB not designed to be operated in the fully submerged mode of a submarine as the centre of gravity 18 always considerably below the centre of buoyancy of the vessel. It will be appreciated that in a conventionally buoyant de, tbe vessel is pressing against the water surface from above, which exposes the vessel to every sort of ~`-hydrodynamic hardship; whereas in the semi-submerged buoyant de, the vessel is pressing against the water surface from below, which reduces the hydrodynamic problems by a factor which may be as high as 50%.
