Definitions

  • the plate arrangement may comprise at least one separation plate.
  • a separation plate may be configured to extend downwardly from the plate arrangement.
  • Such a separation plate may be configured to inhibit objects passing through the hatches to adjacent regions at the platform (e.g. adjacent wells). Further, such a separation plate may be configured to come into contact with a deck as the sheath arrangement is lowered, which may reduce or avoid impact of the sheath arrangement on wellheads.
  • Figure 5 is a diagrammatic illustration of a further example of an offshore platform ;
  • the hatches 472 allow operations to be carried out on the other wells 414 through the apertures 473 when the sheath arrangement 434 is above well 414a.
  • the hatches 472 also allow equipment to be passed through the plate arrangement 470 (e.g. when needed).
  • intervention operations e.g. wireline operations
