An ocean going transport vessel 11 having a pair of hulls 13 15, supporting a first deck 17 located above and extending across the hulls 13 15 toward one end, and forming a structural link between the hulls 13 15. Each hull 13 15 includes a further deck 65 67 extending from the first deck 17 to the other end of the hulls 13 15. Ballast tanks allow adjustment of the draft and trim of the vessel 11. A void 115 extends between the further decks 65 67 and associated hulls 13 15 for stowage or suspension of a load, frame, or deck. The further decks 65 67 extend longitudinally beyond the hulls 13 15 as cantilevered decks 95 97 which each include a docking point 207 arranged to support the vessel by the cantilevered decks, by the docking point 207 resting on a structural support.

1. An ocean going transport vessel comprising a pair of longitudinal hulls spaced apart substantially parallel to each other, supporting a first deck portion located above said hulls, said first deck portion extending across said hulls and forming a structural link therebetween, said first deck portion being located toward one end of said hulls, above the normal operating waterline of said vessel; each said hull including a further deck portion extending at least from said first deck portion to the other end of said hulls, said hulls having a plurality of ballast tanks located therealong provided to allow adjustment of the draft and trim of said vessel, said hulls and said deck portions forming a U-shape when viewed from above and below, having a void extending between opposed said further deck portions and associated hulls, said void being provided for stowage or suspension of a load or subassembly in the form of a cradle, a frame, or a deck, wherein said further deck portions extend longitudinally beyond said hulls, supported in cantilever-type fashion as cantilevered deck portions which each include a docking point arranged to support the vessel by the cantilevered deck portions, by said docking point resting on a structural support. 2. An ocean going transport vessel as claimed in claim 1 wherein each said docking point is located on the underside of each said cantilevered deck portion. 3. An ocean going transport vessel as claimed in claim 1 wherein said docking point includes hydraulic height adjustment to adjust the load on the docking point and/or positioning of the cantilevered deck portions in response to vessel movement due to water movement or displacement variations caused by loading or unloading or in response to ballast tank adjustments. 4. An ocean going transport vessel as claimed in claim 3 wherein said docking point includes load monitoring at said docking point, feeding back to said hydraulic height adjustment, and also feeding back to control of ballast tank levels. 5. An ocean going transport vessel as claimed in claim 1 wherein the length of the void is at least two times the length of the first deck portion. 6. An ocean going transport vessel as claimed in claim 1 wherein said hulls each comprise a pontoon, and said first deck portion and said further deck portions are supported off said pontoons by structure extending between said deck portions and said pontoons. 7. An ocean going transport vessel as claimed in claim 6 wherein said structure comprises a plurality of caissons. 8. An ocean going transport vessel as claimed in claim 7 wherein said structure comprises three caissons extending from each said pontoon. 9. An ocean going transport vessel as claimed in claim 1 wherein said first deck portion provides a superstructure forming at least a bridge for said vessel and optionally workspace and accommodation for crew. 10. An ocean going transport vessel as claimed in claim 1 wherein the vessel includes at least one overhead gantry supported on and extending between the further deck portions for supporting hoists, cranes, for performing lifting and loading/unloading functions. 11. An ocean going transport vessel as claimed in claim 10 wherein said first deck portion and said further deck portions are contiguous, to allow said gantry to be run forward onto the first deck portion. 12. A loading system in combination with an ocean going transport vessel as claimed in claim 10, said loading system comprising providing in a wharf or at an open end of a dry dock, a structural support arranged in spaced configuration to support said cantilevered deck portions from underneath, said cantilevered deck portions being able to receive one or both of said gantries for loading and unloading said vessel. 13. A loading system in combination with an ocean going transport vessel as claimed in claim 12 wherein said structural support is arranged in spaced configuration to support said cantilevered deck portions from underneath contacts said docking point. 14. An ocean going transport vessel as claimed in claim 1 wherein the void is configured to removeably accommodate a subassembly which can be raised and lowered to a required height. 15. An ocean going transport vessel as claimed in claim 14 wherein said subassembly is carried in or on vertically extending tracks secured to said vessel located in spaced relation along the longitudinal extent of said void. 16. An ocean going transport vessel as claimed in claim 15 wherein said subassembly can be secured at different heights along said vertically extending tracks. 17. An ocean going transport vessel as claimed in claim 16 wherein said subassembly includes mechanisms arranged to engage with pins which extend in said vertically extending tracks. 18. An ocean going transport vessel as claimed in claim 17 wherein said pins are located recessed within said vertically extending tracks, and said mechanisms engaging with said pins also are locatable recessed within said vertically extending tracks, restraining said sub assembly against fore and aft movement. 19. An ocean going transport vessel as claimed in claim 14 wherein said subassembly includes removeable transverse bracing extending between and securable in opposed said vertically extending tracks. 20. An ocean going transport vessel as claimed in claim 1 wherein said vessel is provided with deck extensions which may be deployed to extend the further deck portions longitudinally beyond the longitudinal extent of said further deck portions (away from said first deck portion).
