Description

KORT OG SØYLEFORMET ELEMENT SHORT AND COLUMN-FORMED ELEMENT

Oppfinnelsens tekniske område Technical field of the invention

Den foreliggende oppfinnelsen angår tanker for lagring og transportering av fluider slik som hydrokarboner, inkludert lavtemperatur flytende naturgass. Dette inklude-rer tanker for skip og flytende offshore-strukturer utsatt for bølgelaster så vel som tyngdekraftbaserte offshore-strukturer og tanker på land utsatt for jordskjelv. The present invention relates to tanks for storing and transporting fluids such as hydrocarbons, including low-temperature liquefied natural gas. This includes tanks for ships and floating offshore structures exposed to wave loads as well as gravity-based offshore structures and tanks on land exposed to earthquakes.

Bakgrunn for oppfinnelsen Background for the invention

Tanker kan bli utformet i mange forskjellige konfigurasjoner, sånn som kuler, sy-lindre, kjegler og generelt skjellformede, så vel som prisme-former. Den viktigste fordelen med prisme-former er at de ligger nærmere hverandre, noe som minime-rer volumet som slike tanker opptar. Enkle prismatiske tanker er strukturelt mye mindre effektive siden de baserer seg på bøyevirkning for mobilisering av styrke. Skjell utvikler styrke gjennom direkte spenning i planet til skjellet. Dette utvikler høyere styrke med den samme mengden av materiale. Tanks can be designed in many different configurations, such as spheres, cylindrical, cones and generally shell-shaped, as well as prismatic shapes. The most important advantage of prism shapes is that they are closer together, which minimizes the volume that such tanks take up. Simple prismatic tanks are structurally much less efficient since they rely on bending action for the mobilization of strength. Shell develops strength through direct tension in the plane of the shell. This develops higher strength with the same amount of material.

En mer effektiv måte å designe prisme-former er å inkorporere interne stag (spenningsbjelker). Ved å utvikle stag som det viktigste middelet for å begrense den interne lasten eller trykket, er slike prismatisk oppstagede tanker sammenlignbare med skjellformede i strukturell effektivitet. WO 2006/001711 A2 beskriver slike tanker og er herved inkorporert ved referanse. A more efficient way to design prism shapes is to incorporate internal braces (tension beams). By developing struts as the primary means of limiting the internal load or pressure, such prismatic braced tanks are comparable to shell-shaped in structural efficiency. WO 2006/001711 A2 describes such tanks and is hereby incorporated by reference.

Bortsett fra å utvikle strukturell styrke demper staget sloshing, indusert av bølge-bevegelser. De horisontale lastene på spenningsstaget grunnet sloshing blir absor-bert av bjelkene og for å begrense bøying må bjelkene være knyttet sammen ved hvert krysningspunkt. Bjelkene er organisert i vekslende ortogonale lag. Apart from developing structural strength, the brace mitigates sloshing, induced by wave motion. The horizontal loads on the tension strut due to sloshing are absorbed by the beams and to limit bending, the beams must be tied together at each crossing point. The beams are organized in alternating orthogonal layers.

Sloshing-krefter forårsaker vinkelforskyving av stagene i forskjellige lag. Vrid-ningsmomentene indusert i de korte og søyleformede elementene ville vært ekst-remt store i forhold til en praktisk geometri for tverrsnittet av de korte og søyle-formede elementene hvis disse tilveiebringer en rigid sammenholding. For å tilveiebringe vridningsfleksibilitet i kombinasjon med tilstrekkelig skjærstyrke og mot-standsdyktighet for bøying sideveis, blir det anvendt et korsformet tverrsnitt for det korte og søyleformede elementet. Det korsformede tverrsnittet kan være av varia-bel tykkelse og kan også inkorporere spor eller fordypninger for å optimalisere spenningsfordelingen i forhold til styrke og utmatting. Tverrsnittet kan også bli mo-difisert for å inkorporere alt fra tre eller flere plater sentrert i en felles akse. Sloshing forces cause angular displacement of the struts in different layers. The twisting moments induced in the short and columnar elements would be extremely large in relation to a practical geometry for the cross-section of the short and columnar elements if these provide a rigid connection. In order to provide torsional flexibility in combination with sufficient shear strength and resistance to lateral bending, a cross-shaped cross-section is used for the short and columnar element. The cross-shaped cross-section can be of variable thickness and can also incorporate grooves or recesses to optimize stress distribution in relation to strength and fatigue. The cross-section can also be modified to incorporate anything from three or more plates centered on a common axis.

De korte og søyleformede elementene kan være forankret ved å sveise en eller flere baseplater med plass til bolter, sveiser eller andre midler for tilknytning til staget. The short and columnar elements can be anchored by welding one or more base plates with space for bolts, welds or other means of connection to the strut.

Formålet for oppfinnelsen The object of the invention

Formålet for den foreliggende oppfinnelsen er å tilveiebringe en kobling mellom ortogonale kryssende bjelker i vekslende lag. Denne koblingen må være i stand til å absorbere relative vinkelforskyvinger av bjelker i vekslende lag og på same tid forankre bjelkene til de transversale bjelkene over og under. The purpose of the present invention is to provide a connection between orthogonal crossing beams in alternating layers. This connection must be able to absorb relative angular displacements of beams in alternating layers and at the same time anchor the beams to the transverse beams above and below.

Sammendrag av oppfinnelsen Summary of the invention

Formålet for den foreliggende oppfinnelsen blir oppnådd ved å koble sammen transverse stag med flere korte og søyleformede elementer som er fleksible i vrid-ning og rigide i bøying og skjær. Oppfinnelsen ifølge den foreliggende pat-entsøknaden omfatter: En sammenstilling av ortogonale spenningsbjelker i vekslende horisontale lag for anvendelse i en tank, hvori i det minste noen av krysningspunktene mellom de ortogonale spenningsbjelkene er knyttet sammen med hverandre ved hjelp av avstandselementer med bøyestivhet og vridningsfleksibilitet. The purpose of the present invention is achieved by connecting transverse struts with several short and column-shaped elements which are flexible in torsion and rigid in bending and shear. The invention according to the present patent application comprises: An assembly of orthogonal tension beams in alternating horizontal layers for use in a tank, in which at least some of the crossing points between the orthogonal tension beams are connected to each other by means of spacers with bending stiffness and torsional flexibility.

Et avstandselement for anvendelse i en sammenstilling som beskrevet over, hvori nevnte element har to grunnplater knyttet sammen ved hjelp av flere plater kryssende gjennom en felles akse og hvor denne aksen krysser begge av de to grunnplatene. A spacer element for use in an assembly as described above, in which said element has two base plates joined together by means of several plates crossing through a common axis and where this axis crosses both of the two base plates.

Et foretrukket avstandselement er et hvor platene som krysser har et korsformet tverrsnitt og har fortrinnsvis en felles akse vinkelrett i forhold til grunnplatene. A preferred spacing element is one where the plates that cross have a cross-shaped cross-section and preferably have a common axis perpendicular to the base plates.
