Description
- The present disclosure relates to a watercraft system.
- In particular it relates to a submarine or a submersible comprising a number of modules that may be assembled and disassembled.
- It is known to alter the configuration of vehicles by disassembling and then reassembling them to include additional or alternative components. For large vehicles which must be water and/or airtight, for example a watercraft, typically this is done by splitting a hull by cutting through it, inserting a section, and then welding the new combination of sections together. Hence typically the joins made between the sections of the hull are permanent, and configured to be made only once and kept that way for the rest of the life of the watercraft.
- Additionally equipment inside a watercraft may need replacing for repair and/or to be upgraded, which is typically done by dismantling the equipment and removing it through existing hatches and doorways. If the equipment is large, it may instead be removed and replaced by cutting a hole in the side of the watercraft which is later closed by attaching a plate with a welding process.
- Such conventional methods take a great deal of time and must be done very carefully to ensure rest of the watercraft is adequately supported while the hull is weakened. Also such conventional methods can only be done a small number of times before the integrity of the watercraft is reduced.
- As such significant work happens rarely in the life of a large vessel, conventional methods are entirely adequate. However where testing of different variants of a watercraft, or frequent changes in operational requirements of a watercraft arise, conventional reconfiguration methods mean that a vessel can only be adapted a small number of times before its configuration cannot be significantly further adjusted, and an alternative vessel must be used.
- Hence a watercraft system which may be re-configured easily and repeatedly is highly desirable.

The watercraft system according to the present disclosure is alternatively or additionally operable to be disassembled so that additional and/or replacement equipment for the operation of the watercraft system, or equipment that requires testing, may be located in the watercraft system. - The
watercraft system 10 is illustrated with reference toFigs. 1 to 5 . Thewatercraft system 10 of the present disclosure may be, as illustrated, a submarine (e.g. a submersible configured to be submerged in water). Thewatercraft system 10 comprises a water/air tightsealable hull 12, for example a pressure hull, having alongitudinal axis 14. Hence thehull 12 defines a pressure vessel. Thewatercraft system 10 and/or thehull 12 extends between anaft end 16 and aforward end 18. Theaft end 16 is spaced apart from theforward end 18 by thelongitudinal axis 14. - As shown in

Thefirst hull module 100 comprises a first interface element 102 (for example flange or other joining interface feature) which defines, bounds and/or extends around a firsthull module opening 106. That is to say, thefirst hull module 100 may have a firsthull module opening 106, which is bounded by thefirst interface element 102. - The
second hull module 200 defines theforward end 18, and hence may be closed at theforward end 18.

That is to say, thesecond hull module 200 may have a secondhull module opening 206, which is bounded by thesecond interface element 202. - Hence each of the

Thefirst interface element 102 andsecond interface element 202 are configured and operable to be uncoupled from one another as shown inFig. 2 . - Hence the
watercraft system 10 according to the present disclosure is operable as a vessel (e.g. submarine or a submersible configured to be submerged in water) with thefirst interface element 102 of thefirst hull module 100 coupled to thesecond interface element 202 of thesecond hull module 200 as shown inFigure 1 . - Additionally the
watercraft system 10 according to the present disclosure is operable as a vessel (e.g. submarine or a submersible configured to be submerged in water) with thefirst hull module 100 and thesecond hull module 200 coupled together by at least one additional module 300 (e.g. a third module 300) provided between thefirst hull module 100 and thesecond hull module 200 as shown infigure 5 . In such an example the at least one additional module (e.g. a third module 300) is configured to be uncoupled from thefirst hull module 100 andsecond hull module 200. - Hence the
hull 12 of thewatercraft system 10 may adapted (e.g. reconfigured, extended) to include thethird hull module 300. In such an example, and as shown inFigs. 3 to 5 , thethird hull module 300 has twoends third hull module 300 may have a third interface element 302 (for example flange or other joining interface feature) at oneend 316 which defines, bounds and/or extends around a third hull module first opening 306, and a fourth interface element 304 (for example flange or other joining interface feature) at theother end 318 which defines, bounds and/or extends around a third hull modulesecond opening 308. That is to say, thethird hull module 300 may have a third hull module first opening 306, which is bounded by thethird interface element 302, and/or a third hull modulesecond opening 308, which is bounded by thefourth interface element 304. - Hence the
third hull module 300 defines a cavity (i.e. a sub-chamber) which is delimited at either end by therespective interface elements third hull module 300 defines a cavity (i.e. a sub-chamber) which hasopenings - In one example, the
first interface element 102 of thefirst hull module 100 is configured and operable to couple (e.g. engage) with thefourth interface element 304 of thethird hull module 300 to form a sealed joint, and thefirst interface element 102 of thefirst hull module 100 is configured to be uncoupled from thefourth interface element 304 of thethird hull module 300.

sub-module opening 226 to its sub-chamber. The second sub-module 230 may have a sixth interface element 232 (for example flange or other joining interface feature) which defines, bounds and/or extends around a secondsub-module opening 236 to its respective sub-chamber. Thefifth interface element 222 of the first sub-module 220 andsixth interface element 232 of the second sub-module 230 may be configured and operable to couple (e.g. engage) with each other to form a sealed joint to link the sub-chambers to form a larger chamber. Additionally, thefifth interface element 222 of the first sub-module 220 andsixth interface element 232 of second sub-module 230 are configured and operable to uncouple (e.g. dis-engage) from each other. - As shown in
Figs. 4 ,5 thefirst hull module 100,third hull module 300 and second hull module first sub-module 220 are provided in series along thelongitudinal axis 14. - As shown in
Figs 1 to 5 the second hull module second sub-module 230 extends from the second hull module first sub-module 220 in a direction perpendicular to thelongitudinal axis 14. - The openings in each module and sub-module are sized according to need. However, they may be at least large enough for a crew member to pass through. At least one of the openings may be substantially the same as the internal diameter of it respective sub-chamber.
- Adjacent interface elements of the hull modules are coupled (e.g. joined together) by a fixing means 400 which extend therebetween. The fixing means 400 may have a first configuration in which the adjacent interface elements are coupled (e.g. engaged) with one another. The fixing means 400 may have a second configuration in which the adjacent interface elements are operable to be un-coupled (e.g. dis-engaged) from one another. Hence the fixing means are configured to join and the hull modules (and sub-modules) together, and also configured and operable to be dis-engageable to allow the hull modules (and sub-modules) to be disconnected from one another.
- The fixing means 400 may be provided as a nut and bolt (or stud), or other appropriate fixing which allows the for engagement and disengagement.

watercraft system 10 according to the present disclosure may comprise the step of providing thethird hull module 300 and coupling thefirst interface element 102 of thefirst hull module 100 with thefourth interface element 304 of thethird hull module 300 to form a sealed joint between thefirst hull module 100 and thethird hull module 300, and coupling thesecond interface element 202 of thesecond hull module 200 with thethird interface element 302 of thethird hull module 300 to form a sealed joint between thesecond hull module 200 and thethird hull module 300. That is to say, the method of operation of thewatercraft system 10 according to the present disclosure may comprise the step of coupling thefirst interface element 102 of thefirst hull module 100 with thefourth interface element 304 of thethird hull module 300 to form a sealed joint between thefirst interface element 102 of thefirst hull module 100 and thefourth interface element 304 of thethird hull module 300, and coupling thesecond interface element 202 of thesecond hull module 200 with thethird interface element 302 of thethird hull module 300 to form a sealed joint between thesecond interface element 202 of thesecond hull module 200 with thethird interface element 302 of thethird hull module 300 to form a sealed (i.e. water/air tight) chamber. - A method of operation of a
watercraft system 10 according to the present disclosure may comprise the step of entering afirst equipment module 500 through one of the watercraft hull module openings and sliding thefirst equipment module 500 along the mountingrail 502 to move in a direction along thelongitudinal axis 14, and securing (e.g. locking) theequipment module 500 in position relative to the respective hull module. - The method may further comprise the step of removing the

That is to say, the hull modules and (where present, sub modules) may be taken apart so they may be packed into another vehicle for transport.
- Hence there is provided a
watercraft system 10 comprising modular (and optionally sub-modular) hull sections which may be coupled and uncoupled when required, many times. - This enables the volumetric size (i.e. capacity) of the
watercraft system 10 to be adjusted. - This also enables equipment inside the
watercraft system 10 to moved, removed, replaced, fitted as required. This has significant maintenance advantages since it means that any equipment which needs to be repaired, reconfigured, updated and/or fixed can be entirely removed from thewatercraft system 10 so that it may be worked on more easily outside of the vehicle. This also means that asubstitute equipment module 500 can be installed in thewatercraft system 10 to get it operational as soon as possible rather than waiting for theformer module 500 to be repaired. - For example, being able to assemble and dissemble the hull modules (for example using nut and bolt (or stud) to fix them together allows the aft end of watercraft to be rapidly removed for the purposes of easy maintenance and replacement of an external motor drive unit and control surface actuation systems, and rapid re-configuration of the aft end of the submarine to investigate improved stern plane and propulsion concepts.
- The ability to increase and reduce the number of whole modules and sub-modules making up the
watercraft system 10 also provides great operational flexibility. Hence awatercraft system 10 may be quickly configured to meet the needs of a particular operational role or test by adapting thewatercraft system 10 to have the required number of hull modules to fit the desired amount of equipment. - Additionally the modular nature of the
watercraft system 10, and that the modules are configured to be coupled and decoupled from one another, means that the watercraft can be transported more easily in a further vehicle, for example anaircraft 600.Figure 6 illustrates an example arrangement in which disassembled modules (thefirst module 100,first sub module 220, bridge fin 240) may be located in, and distributed betweencargo aircraft 600. Hence thewatercraft system 10 can be broken down into the individual hull modules and positioned in one or more transport vehicles. Hence once disassembled thewatercraft system 10 modules, including the hull modules andequipment modules 500, may be transported in an aircraft, by lorry or train or in another water vessel as required, where space in the transport vehicle would otherwise be too limited to accommodate the assembledwatercraft system 10. - Attention is directed to all papers and documents which are filed concurrently with or previous to this specification in connection with this application and which are open to public inspection with this specification, and the contents of all such papers and documents are incorporated herein by reference.
