X-Span

  • Deepwater Freespans <3000m
  • No down lines
  • No prefabricated structures
  • Sets at low temperature in minutes

X-Span revolutionises subsea, deepwater pipeline span rectification. It is a resin based system that addresses the key issues faced by operators of deepwater facilities when trying to implement grouted and prefabricated span support solutions.
X-Span is deployed on a ROV driven subsea skid. It contains a two part resin that once combined, has a density of 2000kg/m3, is mixed at depth at the span and sets in under 10 minutes providing a fully flexible solution.

Subcon’s X-Span Subsea Pumping Skid is an ROV powered, integrated resin batching plant comprising of pressure compensated reservoirs, twin progressive cavity pumps and ROV Class 1-4 Drive.   The spread can be customised to pump various two part resins into subsea applications via a static mixer.  Installation times can be reduced by up to 90% by replacing cementitious grouts with resins.  Resin densities up to 1.96sg can be pumped continuously in water depths up to 3000m.
