Definitions

  • the invention relates to a vessel and a method for building a vessel.
  • DE 1191710 discloses a vessel comprising a floating body, wherein two propulsion units are attached to a hull.
  • the vessel is a push boat and is designed for pushing barges.
  • a side of the vessel is provided with push supports for engaging push supports of a barge to the pushed.
  • One object of the invention is to enable a vessel to be built more cheaply, more simply, lighter, and/or faster compared with conventional building (in one piece). Another object of the invention is to provide freedom in underwater hydrodynamics, deck space, length, width, draught and exploitation possibilities. A further object of the invention is to provide an almost unsinkable vessel.
  • the invention provides a modularly built vessel according to claim 1.
  • the vessel comprises in particular two construction parts, at least, a main strength frame and a floating body.
  • the main strength frame can be manufactured of a first material which is resistant to forces of screw propellers and of the contact sides in one horizontal plane.
  • the vessel further comprises a floating body which has been built separately.
  • the floating body may be manufactured of a second material, different from the first material.
  • To the floating body preferably, no propulsion units are attached.
  • the main strength frame and the floating body are preferably rigidly connected to create one vessel.
  • This modular vessel of which the floating body and the main strength frame have been built separately, can be built more cheaply, more simply, lighter, and/or faster compared with a vessel in one piece. With such vessel, moreover, there is provided freedom in underwater hydrodynamics, deck space, length, width, draught and exploitation possibilities. Furthermore, the modular vessel is almost unsinkable.
  • the floating body serves substantially exclusively to create buoyancy. Because there are preferably no propulsion units attached to the floating body, and because there are no other spaces needed to accommodate tanks, etc., the floating body can have freedom in shape. In other words: the floating body is preferably not provided with such components (such as propulsion units and tanks).
  • the invention comprises various extra advantageous further elaborations.
  • the above-mentioned first material can be, for example, steel.
  • the main strength frame can contain one or more propulsion units.
  • the second material can be at least one of PE, polyester, carbon fibre, steel, aluminium, and any reusable material.
  • the floating body can contain a single-walled and/or double-walled construction.
  • the floating body is built up from at least a series of floating elements.
  • the floating body or the floating elements thereof may be wholly or partly manufactured by moulding, in particular rotational moulding (also: rotomoulding).
  • the floating body or the floating elements therefor can be substantially empty (hollow), in particular, can enclose a hollow interior (floating chamber).
  • the floating body may be filled with a floating material, for example, foam, empty PET bottles or lightweight balls.
  • a floating material for example, foam, empty PET bottles or lightweight balls.
  • the floating bodies or the floating elements can be full, for example, foamed.
  • the main strength frame can contain a wheelhouse and/or accommodation and/or battery storage.
  • the invention further provides a main strength frame, a floating body, and a method for building a vessel.
  • vessel should be understood to mean at least, though not limited to, a push tug, an aid boat, a ship maintenance boat or a boat with which maintenance on waterways, bridges and harbours can be carried out.
  • Such vessels are usually also referred to as workboats.
  • workboats Such vessels are usually also referred to as workboats.
  • other vessels can be implemented according to the invention.
  • the drawings show a modularly built vessel W according to an exemplary embodiment.
  • this is a push tug for push barges and like vessels to be pushed.
  • the vessel W comprises a main strength frame 1 made of a first material which is resistant to forces of screw propellers and of the contact sides in one horizontal plane.
  • the vessel W further comprises a floating body 2 which has been separately built of a second material, which may be different from the first material, while the floating body 2 has no propulsion units 3 attached in it or to it.
  • the main strength frame 1 and the floating body 2 though, may also be built of the same material, or from combinations of materials.
  • the main strength frame 1 and the floating body 2 have been rigidly connected to create one vessel W.
  • main strength frame 1 should be understood to mean at least a construction with which at least forces extending in a substantially horizontal plane can be transmitted, such as, for example, driving forces produced by screw propellers or like drives, and, for example, pushing forces which are transmitted by the vessel to, for example, a flat-bottom craft or like vessel to be pushed.
  • the main strength frame can comprise, for example, as shown in Fig. 6 , a substantially metal construction, including, for example, frame members 4 which support a deck 5, a covering 6 which forms a bow 7, stern 9 and flanks 10, and an underside 11 by which the main strength frame 1 can rest on the floating body 2.
  • Fig. 6 a substantially metal construction, including, for example, frame members 4 which support a deck 5, a covering 6 which forms a bow 7, stern 9 and flanks 10, and an underside 11 by which the main strength frame 1 can rest on the floating body 2.
  • the main strength frame 1 has openings 12 around which the frame members 4 and covering 6 have been arranged.
  • the main strength frame can be implemented relatively still lighter and yet sufficiently strong.
  • the floating body 2 can be accessed through those openings 12, for example for inspection, and be anchored to the main strength frame 1.
  • the frame members 4, of course, can also be manufactured from a different material, for example plastic or composite, while the covering can be made from any suitable material, for example metal and/or plastic.
  • two push supports 13 are provided on the side of the bow 7. These are firmly connected with the main strength frame 1 and, in embodiments, constitute a constructional component thereof. Via the push supports 13, pushing forces on, for example, a flat-bottom craft or barge 14 can be transmitted still better to the main strength frame 1 and vice versa.
  • This modular vessel W of which the floating body 2 and the main strength frame 1 have been built separately, can be built more cheaply, more simply, lighter, and/or faster compared with a vessel in one piece. With this vessel, moreover, there is provided freedom in underwater hydrodynamics, deck space, length, width, draught and exploitation possibilities. Furthermore, the modular vessel W is almost unsinkable.
  • the floating body serves substantially exclusively to create buoyancy. Because there are no propulsion units 3 attached to the floating body 2, and because there are no other spaces needed to accommodate tanks, etc., the floating body 2 can have freedom in shape.
  • driving forces or thrust forces F generated by the propulsion unit or propulsion units are preferably directly transmitted to the main strength frame 1, that is, without intervention of the floating body. If thereupon, for example, a flat-bottom craft or barge or the like is pushed with the vessel W, those thrust forces F are directly transmitted to the flat-bottom craft or barge 14 or the like.
  • the floating body 2 preferably does not play a role here, other than keeping the vessel W floating.
  • the first material can be, for example, steel.
  • the main strength frame 1 can contain, for example, one or more propulsion units 3.
  • the second material can be, for example, a plastic.
  • the second material can be, for example, at least one of PE, polyester, carbon fibre, steel, aluminium, and any reusable material.
  • the floating body 2 can contain, for example, a single-walled and/or double-walled construction.
  • the floating body 2 can be, for example, empty. Thus, buoyancy can be created.
  • the floating body 2 may for example be filled with a floating material, for example foam, empty PET bottles or lightweight balls.
  • the main strength frame 1 can contain a wheelhouse 15 and/or accommodation 16 and/or battery storage 17 and/or another power pack 18.
  • a method for building a vessel W comprises: manufacturing a main strength frame 1 of a first material which is resistant to forces of screw propellers and of the contact sides in one horizontal plane; separately building a floating body 2 of a second material, preferably different from the first material, while no propulsion units 3 are attached to the floating body 2; and rigidly connecting the main strength frame 1 and the floating body 2 to create one vessel W.
  • the propulsion units 3 are preferably at a distance from the floating body 2, for example near a rear side of the vessel W.
  • the propulsion units 3 extend at an underside 11 of the main frame 1.
  • the floating body 2 can comprise, for example, a floating body 2 extending convexly under the underside 11 of the main frame 1.
  • the floating body has, for example, a curved underside 19. It will be clear that the floating body 2 may be shaped in different manners.
  • the main frame 1 in this example has a rectangular shape, but this is not requisite.
  • the floating body 2 can be built up, or provided, as a substantially hollow plastic and/or metal body.
  • the floating body is formed hollow using plastic forming technique, in particular plastic moulding.
  • a floating body 2 is formed with the aid of at least rotational moulding. With this technique, relatively simply, hollow bodies can be formed from plastic, whose shape can be substantially determined by the mould.
  • a floating body may be formed, for example, by glass fibre technique, for example with the aid of polyester, metal sheet or combinations thereof.
  • a floating body 2 of a vessel W can be manufactured as a one-piece entity.
  • Fig. 3A and Fig. 3B schematically show in side view and bottom view a hull of a vessel W in an alternative embodiment.
  • the floating body 2 is built up from a plurality of sub floating bodies 20, which have been separately manufactured and then connected with each other and with the main strength frame 1.
  • the sub floating bodies 20 can be manufactured, for example, by rotational moulding from plastic, or in a different way and/or from different materials as mentioned earlier.
  • the advantage is achieved that the sub floating bodies are simpler to manufacture than a single floating body having the size of the assembled sub floating bodies.
  • a smaller mould and apparatus can be used, which has both production-technical and economic advantages.
  • sub floating bodies 20 in particular inherently closed, waterproof sub floating bodies, can provide the advantage that sufficient buoyancy for the vessel can be preserved if, for example, one of the sub floating bodies were to become leaky.
  • forming a floating body 2 from different sub floating bodies 20 can provide the advantage that a sub floating body 20 can be simply removed individually, for example for maintenance or to be replaced, in some embodiments even while the vessel keeps floating.
  • a further advantage of the use of sub floating bodies 20 may be that the shape and dimensions of a floating body 2 can be relatively simply adapted, for example by adding or removing sub floating bodies 20.
  • a floating body 2 is built up from eight sub floating bodies 20 but it will be clear there may be more or fewer than eight involved.
  • a floating body 2 may also be formed differently, for example as a multi hull floating body, such as, for example, a catamaran or trimaran.
  • one or more sub floating bodies may be omitted, or be replaced with parts of a different form, such as, for example, an open filling part in which, for example, ballast or load can be received.
  • vessels such as workboats are shown in different implementations, where, as for example in Figs. 1-4 , 7A and 7B , the main frame 1 to some extent overhangs the floating body 2 on all sides.
  • the main frame 1 in these embodiments has a substantially rectangular outer shape. Naturally, that shape may also be chosen differently.
  • the overhanging main frame can provide as an advantage that the floating body is thereby protected relatively well, for example from damage when the vessel is being used, for example, for pushing a barge or flat-bottom craft, or the like, or at quays and the like.
  • propulsion units 3 are mounted on the main strength frame 1.
  • two propulsion units 3 are provided.
  • one propulsion unit 3 could also suffice, or, for example, three or more.
  • one propulsion unit 3 could be provided at the bow 7, and two at the stern 9.
  • Use of at least two propulsion units 3, for example next to each other, provides the possibility to use the propulsion units 3 for steering the vessel W, so that, for example, a separate rudder unit can be dispensed with.
  • azimuth propellers are used as propulsion units 3. These can be, for example, well mounted thrusters, deck mounted thrusters, transom thrusters or tunnel thrusters. In advantageous embodiments, as propulsion units 3, electric screws or propellers are used as propulsion units 3. In advantageous embodiments, electric azimuth propellers or thrusters 3 are used, preferably well mounted electric azimuth thrusters. With these, a relatively low energy consumption can be obtained, with a relatively shallow draught and high manoeuvrability.
  • the propulsion units 3 are mounted on the underside 11 of the main frame 1, at the stern 9, adjacent two opposite corners of the main frame 1, in a part 21 thereof projecting beyond the floating body 2.
  • a generator 22 for generating electric energy.
  • a generator 22 can be, for example, a generator driven by a fossil or non-fossil fuel, for example, though not limited to, petrol, gas oil, (bio) diesel, GTL, methanol, LNG, CNG, solar or fuel cell or the like.
  • the power pack 18 is formed by batteries/accumulators, without generator.
  • the generator 22 is coupled on one side via a transmission 23 with the propulsion unit 3 and on the other side with an accumulator/battery storage 17.
  • the battery storage 17 can function as energy storage for later use by the propulsion unit and/or for other electric installations on board of the vessel W and/or externally of the vessel W.
  • the generator 22 may also be connected with the propulsion unit or units via the battery storage 17.
  • the or each power box 18 and/or battery storage 17 is preferably so configured that it can be simply uncoupled from the propulsion unit or units 3, so that the power box 18 and/or the battery storage can be simply exchanged for another power box 18 and/or battery storage 17.
  • a power box can be chosen for which fuel is available or which is most suitable for particular circumstances or because of certain selection criteria, for example on the basis of emission, environmental pollution, energy consumption, legal regulations, preferences of the user or the like.
  • a power box 18 and/or battery storage 17 may be implemented, for example, in or as a container, for example a sea container.
  • the cabins and like deck-superstructure 16 may be wholly or partly exchangeable.
  • a wheelhouse 15 may be arranged in a fixed position or may for example be adjustable in height in a conventional manner.
  • Fig. 8 schematically shows an alternative embodiment of a vessel.
  • the floating body 2 is substantially wholly in line with the outer contour of the main frame 1, so that there is no or substantially no overhang of the main frame 1 beyond the floating body 2.
  • the propulsion units 3 are attached against the rear side 9 of the main frame 1, for example as deck mounted or transom thrusters.
  • a more (semi)permanent deck superstructure 16 may be provided.
  • a wheelhouse 15 is provided which with the aid of supporting arms 25 may be adjusted in height in a conventional manner.
  • the floating body may comprise, for example, a single row of sub floating bodies 20 or more than two rows, or another arrangement of different sub floating bodies 20, for example staggered, for an augmented mutual connection.
  • Other propulsion units may be used, such as, for example, an outboard motor type of drive unit.
  • the main strength frame may be designed differently, for example as a full-foamed frame, and may have a different configuration.
  • a part thereof may be situated higher or lower, for example a stern may be configured such that it is situated partly next to and/or behind the floating body, for example partly under the waterline, while a propelling unit or propelling units may be provided therein under the waterline.
  • the superstructure above the deck may naturally be implemented differently, for example with a fixed superstructure or a different wheelhouse and the like.
