Skipskonstruksjon. Ship construction.
Nærværende oppfinnelse vedrorer en skipskonstruksjon og tar The present invention relates to a ship construction and takes
sikte på å tilveiebringe en skrogutformning rn.v. som er særlig egnet for gang i isfarvann. Særlig i den senere tid er det sporsmål fremkommet hvorledes man på en hensiktsmessig måte kan transportere olje fra områder hvor farvannet omkring er mer eller mindre isdekket. Spesialskip utformet som en kombinasjon av tankskip og isbryter har vært forsokt, men slike skip faller meget kostbare såvel i anskaffelse som i drift. Også for annen last kan sporsmålet om transport gjennom isfarvann være aktuell f.eks. malmtransport eller annen bulklast. aim to provide a hull design rn.v. which is particularly suitable for walking in icy waters. Particularly in recent times, clues have emerged as to how oil can be transported in an appropriate manner from areas where the surrounding waters are more or less ice-covered. Special ships designed as a combination of tanker and icebreaker have been attempted, but such ships are very expensive both in acquisition and in operation. Also for other cargo, the track target of transport through icy waters may be relevant, e.g. ore transport or other bulk cargo.
Det kjennes fra tidligere forslag til skip som er således konstruert at hovedskroget er beregnet på å ligge under vannflaten og kun skipets overbygninger rager opp over denne. Hensikten med slike tidligere kjente konstruksjoner med neddykket hoved-skrog har vært å oppnå gunstig stromningsmotstand, eventuelt stillere gang gjennom opprort sjo for passasjerbåter. It is known from previous proposals for ships that are constructed in such a way that the main hull is designed to lie below the surface of the water and only the ship's superstructures protrude above this. The purpose of such previously known constructions with a submerged main hull has been to achieve favorable current resistance, possibly quieter passage through rough seas for passenger boats.
Det kjennes også slike delvis neddykkede skip som er konstruert for gang i isfarvann og hvor f.eks. midler har vært foreslått for å bryte isen og for å forsere skroget gjennom denne. There are also such partially submerged ships that are designed for passage in icy waters and where e.g. means have been proposed to break the ice and to force the hull through it.
Oppfinnelsens hensikt er å tilveiebringe en skipskonstruksjon som er særlig egnet for transport av sværere laster f.eks. olje i isfarvann såvel som i vanlig åpen sjo, som har en hoy manov-reringsevne i isen, som har en gunstig utforming for isbryting under de forskjelligste isforhold og som har en sikker stabili-tet under de ulike trimforhold som vil være nodvendige for å oppnå de onskede isbryter- og manoveregenskaper. The purpose of the invention is to provide a ship structure which is particularly suitable for the transport of heavier loads, e.g. oil in icy waters as well as in normal open seas, which has a high maneuverability in the ice, which has a favorable design for breaking ice under the most diverse ice conditions and which has a secure stability under the various trim conditions that will be necessary to achieve the desired icebreaking and maneuvering characteristics.
Ifolge oppfinnelsen oppnås denne hensikt ved å utforme en skipskonstruksjon av semi-ubåttype, hvor skroget i det vesentlige ligger under vannflaten og kun en mindre del som danner skipets overbygning rager opp over denne, idet det nye og karakteristiske er at overbygningen utgjores av to adskilte deler, en forreste og en akterste overbygning mellom hvilke det i langskipsretningen er et åpent mellomrom; at overgangspartiene mellom hovedskroget og nevnte overbygninger er sterkt innsnevret i en for gang i tykk is beregnet vannlinje; at skipets baug er utformet for isbryting og at overbygningenes over nevnte innsnevrede parti beliggende deler vider seg ut med skrå sideflater og utgjor et vesentlig skrogvolum til oppnåelse av reserveoppdrift og langskipsstabilitet. According to the invention, this purpose is achieved by designing a semi-submarine-type ship construction, where the hull essentially lies below the surface of the water and only a smaller part that forms the ship's superstructure protrudes above it, the new and characteristic feature being that the superstructure is made up of two separate parts , a fore and aft superstructure between which in the longship direction there is an open space; that the transition parts between the main hull and said superstructures are strongly narrowed in a previously calculated waterline in thick ice; that the ship's bow is designed for icebreaking and that the parts of the superstructures located above the aforementioned narrowed part expand with sloping side surfaces and form a significant hull volume to achieve reserve buoyancy and longship stability.
Ifolge et ytterligere trekk er baugen utformet med en rygg som krummer seg oppad og går umiddelbart over i forkanten av den forreste overbygning, hvorved nevnte rygg tjener til å bryte is oppover når skipet er trimmet på nevnte vannlinje, mens skipet når det er trimmet for et mindre dypgående kan bryte is på vanlig måte nedover med baugens nedadvendende partier. Ovennevnte samt en rekke ytterligere trekk ved oppfinnelsen vil fremgå klarere av den efterfolgende beskrivelse av en på tegning-en skjematisk vist utfbrelsesform. Fig. 1 viser et sideoppriss av et lasteskip utformet ifolge oppfinnelsen. According to a further feature, the bow is designed with a ridge that curves upwards and passes immediately into the forward edge of the forward superstructure, whereby said ridge serves to break ice upwards when the ship is trimmed on said waterline, while when the ship is trimmed for a less draft can break ice in the usual way downwards with the downward-facing parts of the bow. The above and a number of further features of the invention will appear more clearly from the following description of an embodiment shown schematically in the drawing. Fig. 1 shows a side elevation of a cargo ship designed according to the invention.
Fig. 2 viser skipet ifolge fig. 1 sett ovenifra. Fig. 2 shows the ship according to fig. 1 set from above.
Fig. 3 viser i storre målestokk et tverrsnitt gjennom et skip ifolge oppfinnelsen. Fig. 1 og 2 viser som nevnt rent skjematisk et eksempel på et fartoy ifolge.oppfinnelsen. Med 1 betegnes selve hovedskroget. Dette er forsynt med to overbygninger 2 og 2', dvs. en nær ski-. pets baug og en nær dets akterende. Disse overbygninger inne-holder da foruten lugarer for besetningens underbringelse også kommandorom samt adkomstforbindelser til hovedskroget, ventila-sjonskanaler, rokuttak m.v. Eventuelt kan én av overbygningene som antydet, være utformet med helikopterlandingsdekk. Disse overbygninger har så vidt store dimensjoner at de gir skipet den onskede reserveoppdrift, slik at skipet som helhet kan flyte med onsket vannlinje altefter fylling og tomming av trimtanker. Fig. 3 shows on a larger scale a cross-section through a ship according to the invention. Fig. 1 and 2 show, as mentioned, purely schematically an example of a vessel according to the invention. 1 denotes the main hull itself. This is provided with two superstructures 2 and 2', i.e. one close to the ski-. pet's bow and one close to its stern. In addition to cabins for the crew's accommodation, these superstructures then also contain command rooms as well as access connections to the main hull, ventilation ducts, row outlets, etc. Alternatively, one of the superstructures, as indicated, could be designed with a helicopter landing deck. These superstructures have such large dimensions that they give the ship the desired reserve buoyancy, so that the ship as a whole can float with the desired waterline after filling and emptying trim tanks.
1 2 1 2
I fig. 1 er antydet to vannlinjeplan VL og VL . In fig. 1, two waterline planes VL and VL are indicated.
Skipet ifolge fig. 1 og 2 er utformet med en spesiell isbryter-baug utformet som en spiss 6. Denne går på oversiden jevnt over i forkanten av den forreste overbygning 2, slik som antydet ved 7. I vannlinjen er begge overbygninger avsmalnet slik dette sees ved 8 i fig. 3, men vider seg så ut oventil slik at man får en gunstig form for gang såvel i is som i sjo. Det avsmalnende overgangsparti bidrar til at skipet lett glir gjennom isbeltet, da bredden her er meget liten. The ship according to fig. 1 and 2 are designed with a special icebreaker bow designed as a point 6. This goes smoothly on the upper side into the leading edge of the forward superstructure 2, as indicated at 7. In the waterline, both superstructures are tapered as can be seen at 8 in fig . 3, but then widens upwards so that you get a favorable shape for walking both in ice and sea. The tapering transition section helps the ship easily slide through the ice belt, as the width here is very small.
Skipet er forsynt med drivmotor 3 beliggende i hovedskroget, ror 4 og propeller 5 på i og for seg kjent måte. The ship is provided with drive motor 3 located in the main hull, rudder 4 and propeller 5 in a manner known per se.
Skrogets tverrsnittsprofil kan med fordel være anordnet noe i likhet med den i fig. 3 viste. Skroget er her forsynt med en dobbeltkledning i form av en ytre kledning 9y og en indre kledning 9i. Mellomrommet mellom disse kledninger utgjor ballasttanker. Denne konstruksjon gir for det forste et meget solid skrog som vil tåle påkjenningene av de ismasser gjennom hvilke skipet forseres. Samtidig vil ballasttankene 9 tjene som sik-kerhet for at olj elast som rommes i selve hovedskroget ikke så lett vil kunne lekke ut til det omgivende vann. Dette er som kjent en betingelse ved oljetankskip at de skal være sikret mot oljespill. Ved denne anordning av tankene kan ikke bare skipets trim tilpasses men også dets krengning, hvis dette skulle være fordelaktig for forsering av et isbelte. The cross-sectional profile of the hull can advantageously be arranged something similar to that in fig. 3 showed. The hull is here provided with a double cladding in the form of an outer cladding 9y and an inner cladding 9i. The space between these linings constitutes ballast tanks. This construction provides, firstly, a very solid hull that will withstand the stresses of the ice masses through which the ship is forced. At the same time, the ballast tanks 9 will serve as security so that oil elast that is housed in the main hull itself will not easily leak out into the surrounding water. As is well known, this is a condition for oil tankers that they must be secured against oil spills. With this arrangement of the tanks, not only the ship's trim can be adjusted but also its heeling, if this should be advantageous for forcing an ice belt.
Når skipet ifolge fig. 1-3 går i den neddykkede tilstand som er vist ved vannlinje VL"<1>", er det egnet for gang gjennom kraf-tigere is som brytes opp av det spisse baugparti, og derpå forseres av overbygningens innsnevrede parti 8. Ved gang i is-fritt farvann eller med tynn is, kan fartoyet bringes til å flyte efter vannlinje VL 2, hvorved baugspissen 6 ligger over vannflaten, og baugen vil få en mere almindelig utformning og gang gjennom sjben. When the ship according to fig. 1-3 goes in the submerged state shown at waterline VL"<1>", it is suitable for going through stronger ice that is broken up by the pointed bow section, and then forced by the superstructure's narrowed section 8. When going in ice-free waters or with thin ice, the vessel can be made to float according to waterline VL 2, whereby the bow tip 6 is above the water surface, and the bow will have a more regular design and walk through the sea.
Overbygningene og/eller skrogets overside kan være forsynt The superstructures and/or the upper side of the hull can be provided
med "isror" (ikke vist) for å lette manovrering gjennom isbe-lagt farvann. with "ice rudder" (not shown) to facilitate maneuvering through ice-covered waters.
Videre kan slik manovrering lettes ved at skipets baug og eventuelt akterparti forsynes med én eller flere tversgående kana-ler, i hvilke på i og for seg kjent måte er anordnet en propell e.l. for å kunne tilveiebringe sidetrykk. Furthermore, such maneuvering can be facilitated by providing the ship's bow and possibly the stern with one or more transverse channels, in which a propeller or the like is arranged in a manner known per se. to be able to provide lateral pressure.
Selv om i det ovenstående er beskrevet og på tegningene vist Although in the above described and in the drawings shown
en foretrukket utfbrelsesform og detaljer ved et skip utformet ifolge oppfinnelsen, vil det umiddelbart forstås at en rekke modifikasjoner lett er tenkelige innenfor oppfinnelsens ramme uten derfor å fravike den hovedidé som omfattes av nærværende fremstilling. a preferred embodiment and details of a ship designed according to the invention, it will immediately be understood that a number of modifications are easily conceivable within the framework of the invention without therefore deviating from the main idea covered by the present embodiment.
