Description

Oppfinnelsen angår et oljeoppsamlingsskip med to med et hengsel umiddelbart med hverandre forbundne skipsskroghalvdeler, oljeoppsugingsanordninger som opptar den av skipsskroghalvdelene i utspilt tilstand sammenskjøvne oljemengde, en låseanordning som holder skipsskroghalvdelene parallelt med skipets lengdeakse i ikke utspilt tilstand, samt drivanordninger for drift og manøvrering av skipet både i lukket og i utspilt tilstand, idet overbygningene i det vesentlige befinner seg på en'skipsskroghalvdel. The invention relates to an oil recovery ship with two ship hull halves immediately connected to each other by a hinge, oil suction devices that absorb the amount of oil pushed together by the ship hull halves in the unfolded state, a locking device that holds the ship hull halves parallel to the longitudinal axis of the ship in the not unfolded state, as well as drive devices for operating and maneuvering the ship both in closed and unfolded condition, as the superstructures are essentially located on a ship's hull half.

Et oljeoppsamlingsskip av denne type er kjent fraAn oil collection vessel of this type is known from

DE 2 744 517, hvor de to skipsskroghalvdeler er umiddelbart forbundet med hverandre ved et ledd i akterstevnen og låse-innretningene er anordnet ved bakkens bakre ende. Leddet er utformet som et hengsel med tilsvarende hengseltapp. DE 2 744 517, where the two ship hull halves are immediately connected to each other at a joint in the stern and the locking devices are arranged at the rear end of the ground. The joint is designed as a hinge with a corresponding hinge pin.

I prinsipp har det kjente oljeoppsamlingsskip vært hensiktsmessig. Det har imidlertid vist seg ønskelig, især ved bygging av større enheter, å forbedre kraftoverføringen mellom skipsskroghalvdelene, idet det må tas hensyn til at det foregår betydelige relative bevegelser i forholdsvis store enheter og relativt høy sjøgang med skipsskroghalvdelene i utspilt tilstand og at disse fører til betydelige kref-ter i hengselområdet. In principle, the known oil collection ship has been appropriate. However, it has proved desirable, especially when building larger units, to improve the power transfer between the ship's hull halves, as it must be taken into account that significant relative movements take place in relatively large units and a relatively high draft with the ship's hull halves in an extended state and that these lead to significant forces in the hinge area.

Oppfinnelsen tar sikte på å forbedre det kjente oljeoppsamlingsskip slik at kraftoverføringen i hengselområdet forbedres. The invention aims to improve the known oil collection vessel so that the power transmission in the hinge area is improved.

Dette mål oppnås ifølge oppfinnelsen ved de i krave-nes karakteriserende deler definerte trekk. According to the invention, this objective is achieved by the features defined in the characterizing parts of the claims.

Ved å anordne et flatt hengsel, ifølge oppfinnelsen, sikres en betydelig forbedret kraftoverføring i hengslets område da kreftene mellom de to skipsskroghalvdeler ikke over-føres bare gjennom hengseltappen, men hvor den flate kontakt mellom de to skipsskroghalvdelers hengselflater også står til rådighet, noe som resulterer i betydelig gunstigere moment-forhold i hengselområdet. Videre kan hengslet ifølge oppfinnelsen på spesielt fordelaktig måte anordnes i skipets baug, idet baugen kan gis en strømningsgunstig form, bortsett fra det lukkede skilleplan. Denne konstruksjonsmåte gir også den ytterligere fordel at det som drivanordning for manøvrering av skipet både i lukket og i utspilt tilstand, er tilstrekke- lig med en manøverpropeller eller lignende i hver skipsskroghalvdels hekk, slik at det ikke nødvendigvis er behov for hjelpedrivanordninger slik tilfellet er ved de kjente skip. Låseinnretningen befinner seg ved denne konstruksjonsmåte naturligvis fortrinnsvis nær skipets hekk. By arranging a flat hinge, according to the invention, a significantly improved force transmission is ensured in the area of the hinge as the forces between the two ship hull halves are not transferred only through the hinge pin, but where the flat contact between the hinge surfaces of the two ship hull halves is also available, which results in significantly more favorable torque conditions in the hinge area. Furthermore, the hinge according to the invention can be arranged in a particularly advantageous manner in the ship's bow, as the bow can be given a flow-friendly shape, apart from the closed dividing plane. This method of construction also gives the further advantage that as a drive device for maneuvering the ship both in closed and in extended state, a maneuvering propeller or similar in the stern of each ship's hull half is sufficient, so that there is not necessarily a need for auxiliary drive devices as is the case with they knew ships. With this construction method, the locking device is of course preferably close to the stern of the ship.

01jeoppsamlingsskipet ifølge oppfinnelsen kan forøvrig benyttes på samme måte for transporter, især også som forsyn-ingsskip til boreanlegg ell., slik tilfellet er med oljeoppsamlingsskipet ifølge DE 2 744 517, også med hensyn til skipets ytterligere hjelpeinnretninger, slik dette er beskrevet i patentskriftet. Incidentally, the oil collection ship according to the invention can be used in the same way for transport, especially also as a supply ship for drilling facilities etc., as is the case with the oil collection ship according to DE 2 744 517, also with regard to the ship's additional auxiliary devices, as described in the patent document.

Ytterligere trekk og fordeler ved oppfinnelsen vil fremgå av den etterfølgende beskrivelse av en utførelse av oppfinnelsen, som vist på tegningen hvor figur 1 viser en ut-førelse av et oljeoppsamlingsskip ifølge oppfinnelsen i side-riss, figur 2 vise oljeoppsamlingsskipet på figur 1 i grunn-riss og figur 3 viser det på figur 1 og 2 viste skip i utspilt tilstand. Further features and advantages of the invention will be apparent from the subsequent description of an embodiment of the invention, as shown in the drawing where Figure 1 shows an embodiment of an oil collection vessel according to the invention in side view, Figure 2 shows the oil collection vessel in Figure 1 in basic drawings and figure 3 show the ship shown in figures 1 and 2 in an unfolded state.

Slik eksemplet på tegningen viser, har oljeoppsamlingsskipet ifølge oppfinnelsen en første skipsskroghalvdel 12 som bærer i det vesentlige alle overbygninger 10, samt en andre skipsskroghalvdel 13. Over et ved skipets baug anordnet heng-selområde 14 griper skipsskroghalvdelen 12, slik det fremgår av tegningen, over hele skipets bredde som dannes av de to skipsskroghalvdelers 12, 13 bredde, over skipsskroghalvdelen 13 som ikke har overbygning idet de to skipsskroghalvdeler har mot hverandre vendende hengselflater 18, 20 som er anordnet horisontalt i et skilleplan 16, hvor skipsskroghalvdelen 12 med overbygninger har en form tilsvarende en sirkelflate hvis diameter er lik den totale skipsbredde. Skipets baug er, slik det fremgår av figur 1 og 2,i det vesentlige lukket bortsett fra det horisontale skilleplan 16 og har sirkelform, idet baugens form i det vesentlige er definert ved hengselområdets 14 form. As the example in the drawing shows, the oil recovery ship according to the invention has a first ship's hull half part 12 which carries essentially all superstructures 10, as well as a second ship's hull half part 13. Over a hinge area 14 arranged at the ship's bow, the ship's hull half part 12, as can be seen from the drawing, grips over the entire width of the ship, which is formed by the width of the two ship hull halves 12, 13, over the ship hull half 13 which has no superstructure as the two ship hull halves have hinge surfaces 18, 20 facing each other which are arranged horizontally in a dividing plane 16, where the ship hull half 12 with superstructures has a shape corresponding to a circular surface whose diameter is equal to the total width of the ship. The ship's bow is, as can be seen from Figures 1 and 2, essentially closed apart from the horizontal dividing plane 16 and has a circular shape, the shape of the bow being essentially defined by the shape of the hinge area 14.

Slik det ses på figur 1, er en manøverpropeller 22 anordnet i hver skipsskroghalvdels akterende. De to manøver-propellere 22 tjener til skipets normalfart, idet begge skipsskroghalvdeler er låst til hverandre med en ikke vist låseinnretning, for drift og manøvrering av skipet. Også i olje- oppsamlingsstillingen som er vist på figur 3, hvor de to skipsskroghalvdeler spriker omtrent 65° i forhold til hverandre, bevirker manøverpropellerne skipets drift og manøvrering. As can be seen in Figure 1, a maneuvering propeller 22 is arranged in the stern of each ship's hull half. The two maneuvering propellers 22 serve for the ship's normal speed, as both ship hull halves are locked to each other with a locking device not shown, for operation and maneuvering of the ship. Also in the oil collection position shown in figure 3, where the two ship hull halves are spread approximately 65° in relation to each other, the maneuvering propellers effect the ship's operation and manoeuvring.

I forskipet er en ytterligere manøverdrift 23 anordnet, i form av en dyse eller lignende. In the foredeck, a further maneuver drive 23 is arranged, in the form of a nozzle or the like.

Den beskrevne utførelse av oljeoppsamlingsskipet kanThe described design of the oil collection vessel can

i lukket tilstand benyttes for generell transport, især også til forsyning av boreinstallasjoner, men også bl.a. som basisskip for dykkere og ved utlegging av tønner (på grunn av den utmerkede stabilitet og mulighet til å skape lé i utspilt tilstand). De oljeoppsamlingsanordninger som naturlig nok er anordnet i de to skipsskroghalvdeler samt de nødvendige opp-samlingstanker, sikrer ved behov oljeoppsamlingsskipets an-vendbarhet, idet det her henvises til DE 2 744 517 for nær-mere beskrivelse av den fulle utnyttelse i denne forbindelse. in the closed state is used for general transport, especially also for the supply of drilling installations, but also i.a. as a base ship for divers and when laying out barrels (due to the excellent stability and possibility of creating shelter in the unfolded state). The oil collection devices which are naturally arranged in the two ship hull halves as well as the necessary collection tanks, ensure the oil collection ship's usability if necessary, as reference is made here to DE 2 744 517 for a more detailed description of the full utilization in this connection.
