Description

1. Fartøj, fortrinsvis til behandling og opbevaring af olie, med lastekapacitet i det væsentlige omfattet af et enkelt skrog (3) med et hoveddæk (1), kendetegnet ved mindst en i det væsentlige vandret pladeformet dæmperindretning (2), der strækker sig ud på hver side af skroget (3) og befinder sig under vandlinien og med en udstrækning fortrinsvis i hele fartøjets længde. 2. Fartøj ifølge krav 1, kendetegnet ved en eller flere lodrette åbninger (22) i dæmperindretningen (2), der er indrettet til at tillade en begrænset, hovedsagelig lodret vandstrøm gennem dæmperindretningen (2) og således føre til yderligere dæmpning af fartøjets bevægelser, hovedsagelig rulle-, hugge- og duvebevægelser. 3. Fartøj ifølge krav 1,kendetegnet ved, at dæmperindretningen (2) er indrettet med sin nedre side i niveau med fartøjets plane ydre bundflade (40). 4. Fartøj ifølge krav 1, kendetegnet ved en progressivt øgende adskillelse mellem den ydre kant (21) af dæmperindretningen (2) og fartøjets centerlinie fra området nær stævnen (33) til i det væsentlige området nær fartøjets hæk (32). 5. Fartøj ifølge krav 1,kendetegnet ved mindst en stående rand (24) hovedsagelig langs dæmperindretningens (2) yderkant (21), hvor randen (24) er indrettet til at begrænse friheden for vandmassernes vandrette strømning indenfor randen i tværskibs retning og at binde vandmasserne for at bidrage til fartøjets rullende inertimoment. 6. Fartøj ifølge krav 1,kendetegnet ved fremspring eller skrogvinger (4) på hver side af skrogets hæk (3) defineret som en progressiv sideværts forøgelse bagud af skrogets (3) tværsnitsbredde i den agterste del af skroget, og omfattende i det væsentlige mellem afstanden mindre end den agterste fjerdedel af skroget (3) og spejlgattet (32), således at tværsnitsbredden af skroget i det væsentlige forøges langs hele fartøjets dybde. 7. Fartøj ifølge krav 1, kendet egn et ved en i det væsentlige vandret udstrakt dæmperindretning (2') under vandlinien af skrogets (3) hæk (32). 8. Fartøj ifølge krav 7, kendetegnet ved, at dæmperindretningen (2') generelt er pladeformet, fortrinsvis med sin nedre side i niveau med fartøjets plane ydre bundflade (40), og at den udgør bunden i en konkav hvælving eller niche åbning (34) i omkring den nedre halvdel af fartøjets spejlgat (32) og befinder sig i det væsentlige mellem fremspringene (4). 9. Fartøj ifølge krav 7 eller 8, kendetegnet ved, at dæmperindretningens (2') bagkant (2Γ) mod havet strækker sig parallelt med og er indrettet i det væsentlige direkte under hoveddækkets (1) mod agter vendende ende og er i plan med fartøjets spejlgat (32). 10. Fartøj ifølge krav 7 eller 8, kendetegnet ved, at dæmperindretningens mod agter vendende kant (21 ') mod havet strækker sig som en hovedsagelig konveks bue (2Γ) ud fra hækken (32) og er indrettet til at afvise fartøjer, som ville komme for tæt på hækken (32).A vessel, preferably for the treatment and storage of oil, having a load capacity substantially comprised of a single hull (3) with a main deck (1), characterized by at least one substantially horizontal plate-shaped damper device (2) extending on each side of the hull (3) and located below the waterline and preferably to an extent throughout the length of the vessel. Vessel according to claim 1, characterized by one or more vertical openings (22) in the damper device (2) arranged to allow a limited, substantially vertical flow of water through the damper device (2), thus leading to further dampening of the vessel's movements, mainly rolling, chopping and pigeon movements. Vessel according to claim 1, characterized in that the damper device (2) is arranged with its lower side in level with the plane outer surface of the vessel (40). Vessel according to claim 1, characterized by a progressively increasing separation between the outer edge (21) of the damper device (2) and the vessel's center line from the area near the bow (33) to substantially the area near the stern (32) of the vessel. Vessel according to claim 1, characterized by at least one standing rim (24) mainly along the outer edge (21) of the damper device (2), wherein the rim (24) is adapted to limit the freedom of the horizontal flow of the water within the rim in the transverse direction and to bind the masses of water to contribute to the rolling moment of inertia of the vessel. Vessel according to claim 1, characterized by projections or hull wings (4) on each side of the hull (3) defined as a progressive lateral increase in the rear of the hull (3) cross-sectional width in the rear part of the hull, and comprising substantially between the distance less than the rear quarter of the hull (3) and the mirror hole (32) so that the cross-sectional width of the hull is substantially increased along the entire depth of the vessel. Vessel according to claim 1, characterized by a dampening device (2 ') substantially extending horizontally below the waterline of the hull (32) of the hull (3). Vessel according to claim 7, characterized in that the damper device (2 ') is generally plate-shaped, preferably with its lower side in level with the plane's outer surface (40), and that it forms the bottom of a concave vault or niche opening (34). ) in about the lower half of the vessel's mirror hole (32) and located substantially between the projections (4). Vessel according to claim 7 or 8, characterized in that the trailing edge (2Γ) of the damper device (2 ') towards the sea extends parallel to and is arranged substantially directly under the end of the main deck (1) towards the end of the vessel. mirror hole (32). Vessel according to claim 7 or 8, characterized in that the attenuating edge (21 ') of the damper towards the sea extends as a substantially convex arc (2Γ) from the stern (32) and is adapted to repel vessels which would get too close to the hedge (32).
