Definitions

  • the present invention relates to tanks for storage and transportation of 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 land tanks exposed to earthquakes.
  • Tanks may be designed in many different configurations, such as spheres, cylinders, cones and shells in general, as well as prismatic shapes.
  • the principal advantage of prismatic shapes is that they nest closer to each other, minimising the volume taken up by such tanks.
  • Simple prismatic tanks are far less efficient structurally as they rely on bending action for mobilisation of strength.
  • Shells develop strength through direct tension in the plane of the shell. This develops greater strength for the same amount of material.
  • a more efficient design of prismatic shapes is to incorporate internal stays (tension beams). By developing stays as the main means of restraining the internal load or pressure, such prismatic staid tanks are comparable to shell shapes in structural efficiency.
  • WO 2006/001711 A2 discloses such tanks and is hereby incorporated by reference.
  • the stays dampen sloshing induced by wave motion.
  • the horizontal loads on the tension stays due to sloshing are absorbed by the beams and to limit bending the beams must be connected at each intersection.
  • the beams are organised in alternate orthogonal layers.
  • the object of the present invention is to provide a connection between orthogonally intersecting beams in alternate layers.
  • This connection must be able to absorb relative angular displacement of beams in alternate layers at the same time as anchoring the beams to the transverse beams above and below.
  • a connection should have torsional flexibility in combination with sufficient shear strength and resistance to lateral bending.
  • connection in the form of a stub column having a cruciform cross section In order to provide torsion flexibility in combination with sufficient shear strength and resistance to lateral bending the invention uses a connection in the form of a stub column having a cruciform cross section.
  • the cruciform cross section may be of variable thickness and may also incorporate slots or indentations to optimise the stress distribution with respect to strength and fatigue.
  • the cross section may also be modified to incorporate anything from three or more plates centred into a common axis.
  • the stub columns may be anchored by welding one or more base plates
  • the object of the present invention is obtained by connecting transverse stays by a stack of stub columns flexible in torsion and rigid in flexure and shear.
  • the invention according to the present application comprises:
  • the beams may comprise webs and flanges.
  • the spacer elements are preferably ⁇ connected to the beams by way of bolts, welds or any other suitable fastening means.
  • the spacer elements are preferably connected to the beams by the webs or flanges of the beams.
  • a preferred spacer element is one wherein the plates intersecting are of a cruciform cross section and preferably have a common axis perpendicular to the base plates.
  • Figure 1 shows a perspective view of a cruciform spacer element
  • Figure 2 shows a horizontal cross section including a plan view of the base plate
  • Figure 3 shows some alternative cross sections of a spacer element
  • Figure 4 shows a side view of a cruciform spacer element
  • Figure 5 shows an assembly of cruciform spacer elements and beams anchored by the spacer element.
  • Figure 6 shows a perspective view of the interior of a tank, featuring an assembly of tension beams.
  • Figure 1 shows a perspective view of the spacer element consisting of plates 1 forming a cruciform stub column and two base plates 2 with holes 3 to receive bolts for anchoring the spacer element to the intersecting stays/beams.
  • the spacer element may be manufactured by die forging or fabricated from welded plate, extruded or rolled profiles.
  • Figure 2 shows the spacer element consisting of the cruciform stub column shown in cross section, one of the base plates 2 shown in plane and the bolt holes 3 shown with bolts inserted.
  • Figure 3 show alternative embodiments of the spacer element.
  • Figure 4 shows an elevation of a spacer element with plates 1 forming a cruciform stub column element, two base plates 2 with holes 3 to receive bolts.
  • Figure 5 shows typical details of an assembly of stays/beams 4 shown as I-beams and cruciform spacer elements 5 connected to the webs of the stays/beams 4.
  • Figure 6 shows a perspective view of the interior of a tank, featuring an assembly of tension beams 4 connected by cruciform spacer elements 5 at their intersections.
