Definitions

  • the disclosure provides a riser termination device comprising: (a) substantially internally flat cover plate; and (b) at least one arm extending from the cover plate; wherein no portion of the cover plate extends above any portion of the at least one arm.
  • external components of the riser section 10 may extend above the level of the openings 14.
  • Such external components may include a cap 16 which may be attached to the vessel 1 in order to stabilize and/or secure the riser section 10.
  • the riser cap 16 may be held in place through one or more straps 18.
  • Straps 18 may be connected to either or both of the vessel 1 and the riser cap 16 in a hinged manner permitting longitudinal and radial expansion and contraction.
  • each strap 18 comprises a tubular rod 20 having two open ends into which a metal strip 21 is inserted.
  • Metal strips 21 are preferably sufficiently pliant to allow some flexion upon thermal expansion and contraction of the riser section 10.
