Description

Oppfinnelsen vedrører et skip med i tverrsnittet helt eller tilnærmet sirkulære eller elliptiske lasttanker med glatte innervegger . The invention relates to a ship with completely or nearly circular or elliptical cargo tanks with smooth inner walls in cross-section.

Lasttanker med glatte innervegger og med helt eller tilnærmet sirkulært eller elliptisk tverrsnitt er kjent i mange utfør-elser. Det skal her eksempelvis pekes på de kjente kuletank-skip og på tank/bulkskip med liggende, stort sett sylindriske eller svakt koniske sylindertanker. Felles for disse kjente løsninger er at lasttankene er plassert i et konvensjonelt skipsskrog, og lasttankene inngår ikke i selve skrogkonstruk-sjonen,slik tilfellet er ved konvensjonelle tankskip. Cargo tanks with smooth inner walls and with a completely or nearly circular or elliptical cross-section are known in many designs. Here, for example, reference should be made to the well-known ball tank ships and to tank/bulk ships with horizontal, largely cylindrical or slightly conical cylinder tanks. What these known solutions have in common is that the cargo tanks are placed in a conventional ship's hull, and the cargo tanks are not included in the hull construction itself, as is the case with conventional tankers.

Ifølge oppfinnelsen foreslås det et helt nytt skipsskrogkonsept, hvor skrogets utforming bestemmes med utgangspunkt i lasttankenes utforming, og hvor lasttankene trekkes inn i skroget som konstruksjonselementer i dette. According to the invention, a completely new ship hull concept is proposed, where the design of the hull is determined based on the design of the cargo tanks, and where the cargo tanks are pulled into the hull as structural elements in it.

Ifølge oppfinnelsen foreslås det derfor et skip med i tverrsnittet helt eller tilnærmet sirkulære eller elliptiske lasttanker med glatte innervegger, hvilket skip er kjennetegnet ved at skrogtverrsnittet har sirkulær eller tilnærmet sirkulær eller elliptisk form, med felles tverrskips rammespant mellom hud/dekk og lasttankene, hvilke rammespant lagrer opp langskips stivere mot hud og dekk. According to the invention, a ship is therefore proposed with a completely or nearly circular or elliptical cross-section of cargo tanks with smooth inner walls, which ship is characterized by the hull cross-section having a circular or nearly circular or elliptical shape, with a common cross-ship frame frame between the skin/deck and the cargo tanks, which frame frames stores longship struts against skin and deck.

Lasttankene er fortrinnsvis sylindriske lasttanker, men kan naturligvis også ha avvik fra den rene sylinderform, eksempelvis stumpkonisk form, i tilpassing til skroglinjene. Tankene kan være adskilt fra hverandre eller bestå av flere etter hverandre anordnede og sammenbyggede tanker. Det kan også dreie seg om en tank, med innvendige tverrskott. Disse tverrskott kan være plane eller mer eller mindre kuppelformede eller veivede, og således kan man også tenke seg en eller flere liggende sylindertanker som i realiteten er satt sammen av kuletanker som går delvis over i hverandre. Tankene kan naturligvis også ved The cargo tanks are preferably cylindrical cargo tanks, but can of course also have deviations from the pure cylindrical shape, for example a frustoconical shape, in adaptation to the hull lines. The tanks can be separated from each other or consist of several tanks arranged one behind the other and built together. It can also be a tank, with internal transverse bulkheads. These transverse bulkheads can be flat or more or less dome-shaped or curved, and thus one can also imagine one or more horizontal cylinder tanks which are in reality composed of spherical tanks which partially merge into each other. Of course, the mind can also use wood

behov ha langskipsskott.need to have longship bulkheads.

Lasttankene vil med sine langskips-partier gå i skipets lengde-retning og vil derfor ta aktiv del i skipets langskipsstyrke. The cargo tanks with their long-ship sections will run in the ship's longitudinal direction and will therefore take an active part in the ship's long-ship strength.

Lasttankene kan være bygget opp av plater som er selvstivende, men tankene kan også alternativt eller i tillegg være stivet av med utvendige langskips stivere som igjen lagres opp av de nevnte tverrskips rammespant. The cargo tanks can be built up from plates that are self-stiffening, but the tanks can also alternatively or additionally be stiffened with external longship stiffeners which are in turn held up by the aforementioned transom frame frames.

Med det nye skipsskrogkonsept oppnås en rekke fordeler.With the new ship hull concept, a number of advantages are achieved.

De nevnte lasttanker vil innvendig være fri for stivere, dvs. at tankene innvendig har glatte vegger. The aforementioned cargo tanks will be free of stiffeners on the inside, i.e. the tanks will have smooth walls on the inside.

Lasttankene kan uten videre utføres som trykktanker.The cargo tanks can easily be designed as pressure tanks.

Antall tanker kan reduseres til et minimum, med dertil forenk-let pumpesystem og rørsystem. The number of tanks can be reduced to a minimum, with a simplified pump system and pipe system.

Det nye skipsskrog vil ha god stabilitet i krenget tilstand. The new ship's hull will have good stability in a heeled condition.

Skipsskrogets midtspant har en form som gir gode skroglinjer og liten motstand. Det skal i denne forbindelse vises til norsk patentsøknad 852828 hvor fordelene med en tilsvarende midtspantform er belyst nærmere. The center span of the ship's hull has a shape that gives good hull lines and little resistance. In this connection, reference should be made to Norwegian patent application 852828, where the advantages of a similar mid-span form are explained in more detail.

Rommet eller rommene mellom indre og ytre hud, mellom lasttankens vegg og skroghuden, kan benyttes til ballast, enkle laster eller brensel. The space or spaces between the inner and outer skin, between the cargo tank wall and the hull skin, can be used for ballast, simple cargo or fuel.

Lasttankene kan benyttes til flytende laster, bulklaster, så-som korn, sement, malm etc., og også—-for-f lytendeg j o-rte ..gasser . The cargo tanks can be used for liquid cargoes, bulk cargoes, such as grain, cement, ore etc., and also—-for liquid dough or ..gases.

Påkjenningene på skipsskroget vil bli langt bedre opptatt iThe stresses on the ship's hull will be far better absorbed

Den nye skrogform utnytter stålet langt bedre enn tilfellet er for eksisterende konvensjonelle skrogformer. The new hull shape utilizes the steel far better than is the case for existing conventional hull shapes.

Oppfinnelsen skal forklares nærmere under henvisning til tegningene, hvor: The invention shall be explained in more detail with reference to the drawings, where:

Fig. 1 viser et sentralt tverrsnitt (ved midtspantet) avFig. 1 shows a central cross-section (at the middle frame) of

et eksempel på det nye skipsskrog, ogan example of the new ship's hull, and

fig. 2 viser et tilsvarende snitt gjennom en modifisert ut-førelse, med flere tanker i tverrsnittet. fig. 2 shows a corresponding section through a modified version, with several tanks in the cross section.

På fig. 1 er det vist et typisk tverrsnitt gjennom det nye skipsskrog. En i tverrsnitt sirkulær lasttank er betegnet med 1. Rundt lasttanken ligger det et rammespant 2 og derpå følger skipsskrogets hud 3 og dekk 4. Rammespantet 2 lagrer opp langskips stivere 5 mot hud og dekk (vist bare for venstre halvpart). Det er også antydet langsgående stivere 6 som er lagret opp i rammespantet 2 mot utsiden av lasttanken 1. In fig. 1 shows a typical cross-section through the new ship's hull. A cargo tank that is circular in cross-section is denoted by 1. Around the cargo tank there is a frame frame 2 and on top of that the ship's hull skin 3 and deck 4. The frame frame 2 stores longship struts 5 against the skin and deck (shown only for the left half). Longitudinal struts 6 are also indicated which are stored up in the frame frame 2 towards the outside of the cargo tank 1.

Skipsskroget i fig. 2 er bygget opp på samme prinsippielle måte som skipsskroget i fig. 1. Den eneste forskjell er at i-stedenfor én lasttank i tverrsnittet her forefinnes fire lasttanker 7, 8, 9 og 10. Et rammespant er også her betegnet med 2, og hud og dekk er også her betegnet med 3 og 4. På samme måte som i fig. 1. Det er i fig. 2 også antydet langskips stivere 5 og 6, hvis plassering og funksjon er den samme som beskrevet og vist foran i forbindelse med fig. 1. The ship's hull in fig. 2 is built up in the same principled way as the ship's hull in fig. 1. The only difference is that instead of one cargo tank in the cross-section here, there are four cargo tanks 7, 8, 9 and 10. A frame frame is also here denoted by 2, and the skin and deck are also here denoted by 3 and 4. On the same manner as in fig. 1. It is in fig. 2 also indicated longship struts 5 and 6, the location and function of which is the same as described and shown above in connection with fig. 1.
