Description

Denne oppfinnelse vedrører en flytende ledning for transport au fluider, omfattende et antall stiv/e rørseksjoner som v/eksler med bøyelige slangeseks joner, hvor huer slangeseksjon forbinder to stive rørseksjoner, og hvor de stive rørsek-sjoner er utstyrt med flottører med tilstrekkelig flyte-evne til å holde ledningen flytende, særlig til bruk ved enkle for-tøyningsbøyer for lasting og lossing av skip. This invention relates to a floating line for the transport of fluids, comprising a number of rigid pipe sections that alternate with flexible hose sections, where each hose section connects two rigid pipe sections, and where the rigid pipe sections are equipped with floats with sufficient floatation ability to keep the line floating, especially for use with simple mooring buoys for loading and unloading ships.

For lasting og lossing av tanksip er det i den senere tid tatt i bruk fortøyningsbøyer som f.eks. beskrevet i britiske patenter 977 451, 1 031 492 og 1 017 894. Disse fortøynings-innretninger er vanligvis utstyrt med lange flytende ledninger for tilveiebringelse av fluidumforbindelse mellom tankeren og fortøyningen, således at lasting og lossing kan finne sted med tankeren fortøyet til bøyen. Mooring buoys such as e.g. described in British patents 977 451, 1 031 492 and 1 017 894. These mooring devices are usually fitted with long floating lines to provide fluid communication between the tanker and the mooring so that loading and unloading can take place with the tanker moored to the buoy.

Disse slanger eller ledninger som er fremstilt av gummi eller lignende bøyelig materiale, er meget lange og har stor diameter, således at de er meget kostbare. Da de dessuten fly-ter permanent på vannflaten, er de særlig utsatt for beskadig-else i tilfelle av dårlig vær. Skader på en slange krever ikke bare utskifting av den kostbare slange, men forårsaker også for-sinkelser ved lasting og lossing av et tankskip. These hoses or wires, which are made of rubber or similar flexible material, are very long and have a large diameter, so that they are very expensive. As they also float permanently on the surface of the water, they are particularly susceptible to damage in the event of bad weather. Damage to a hose not only requires replacement of the expensive hose, but also causes delays when loading and unloading a tanker.

Hensikten med oppfinnelsen er å skaffe en flytende ledning som er billigere og mer motstandsdyktig mot beskadigelser enn de kjente flytende slanger, og dette oppnås ved at hver flottør er utført av et lag skumplastmateriale som er anordnet rundt og integralt med den stive rørseksjon. Den flytende ledning kan derved fremstilles på en billig måte, særlig hvis skumplastmaterialet i henhold til et videre trekk ved oppfinnelsen påføres de stive rørseksjoner ved påsprøyting av polyurethanskum. Laget av skumplastmateriale blir med fordel dob-belt med et beskyttende lag av glassduk impregnert med en epoksyharpiks. The purpose of the invention is to provide a floating line that is cheaper and more resistant to damage than the known floating hoses, and this is achieved by each float being made of a layer of foam plastic material which is arranged around and integral with the rigid pipe section. The floating line can thereby be manufactured in an inexpensive way, especially if the foam plastic material is applied to the rigid pipe sections by spraying polyurethane foam according to a further feature of the invention. The layer of foam plastic material is advantageously doubled with a protective layer of glass cloth impregnated with an epoxy resin.

Oppfinnelsen skal forklares nærmere ved eksempler under henvisning til tegningen, hvis fig. 1 viser et lengdesnitt av en første utførelse av oppfinnelsen, fig. 2 viser et sideriss av oppfinnelsen ifølge fig. 1 og fig. 3 og 4 viser lengdesnitt av en annen henholdsvis tredje utførelse. The invention shall be explained in more detail by means of examples with reference to the drawing, if fig. 1 shows a longitudinal section of a first embodiment of the invention, fig. 2 shows a side view of the invention according to fig. 1 and fig. 3 and 4 show longitudinal sections of a second and third embodiment, respectively.

Tegningen viser stive rør 1 av metall med flenser 2. Ifølge tegningen er hvert av de stive rør 1 utstyrt med en flot-tør som er i ett med røret 1 og består av et lag skumplast 3, såsom polyurethanskum, som er anbragt på røret 1 ved påsprøyt-ing. Skumplastens 3 ytterflate er hensiktsmessig forsynt med et beskyttende lag 4 av glassfibre eller glassdukforsterket epoksyharpiks. Mellom hvert par stive rør 1 er der anordnet en slange 5 som på vanlig vis er utstyrt med metallflenser 6 som er forbundet med flensene 2 ved hjelp av bolter (ikke vist). The drawing shows rigid pipes 1 made of metal with flanges 2. According to the drawing, each of the rigid pipes 1 is equipped with a float that is one with the pipe 1 and consists of a layer of foam plastic 3, such as polyurethane foam, which is placed on the pipe 1 by spraying. The outer surface of the foam 3 is suitably provided with a protective layer 4 of glass fibers or glass cloth reinforced epoxy resin. Between each pair of rigid tubes 1 there is arranged a hose 5 which is normally equipped with metal flanges 6 which are connected to the flanges 2 by means of bolts (not shown).

På fig. 1 og 2 omfatter slangen 5 en vanlig bøyelig ledw-ning, f.eks. av gummi eller et lignende materiale, som er utstyrt med et antall ringformede skumplastflattører 7 som er skjøvet inn på slangen 5. In fig. 1 and 2, the hose 5 comprises a normal flexible joint, e.g. of rubber or a similar material, which is equipped with a number of ring-shaped foam plastic flat ears 7 which are pushed onto the hose 5.

Ved utførelsen ifølge fig. 3 er slangen 5 utstyrt med In the embodiment according to fig. 3, the hose 5 is equipped with

e"t" flytelegeme 8 som er i ett med slangen 5 og består av et lag skumplast eller skumgummi anbragt på slangen 5 i form av særskilte på forhånd fremstilte plater eller ark, eller er ut-ført med et beskyttende lag 9 av slitefast gummi eller poly-urethan. e"t" floating body 8 which is one with the hose 5 and consists of a layer of foam plastic or foam rubber placed on the hose 5 in the form of special pre-made plates or sheets, or is made with a protective layer 9 of wear-resistant rubber or poly-urethane.

Ved utførelsen ifølge fig. 4 er slangen 5 ikke forsynt med noen flytelegemer, idet den nødvendige eller tilstrekke-lige flyte-evne oppnås ved hjelp av flottørene på de stive rør 1. In the embodiment according to fig. 4, the hose 5 is not provided with any floating bodies, as the necessary or sufficient buoyancy is achieved with the help of the floats on the rigid tubes 1.

Polyurethanskummet på metallrørene kan anbringes på metallrørene 1 ved skumming, f.eks. ved påsprøytingsmetoden. The polyurethane foam on the metal pipes can be placed on the metal pipes 1 by foaming, e.g. by the spraying method.

I stedet kan polyurethanskummet bestå av på forhånd fremstilte skåler som anbringes rundt ..metallrørene 1. Instead, the polyurethane foam can consist of pre-made bowls that are placed around the ..metal pipes 1.
