The buoyancy pictured is being used to support the installation of an 18" In Line Tee that will be submerged and placed on the seafloor at a depth of 250m. The structure was built for use on one of the most significant oil and gas projects in the world located off the coast of Western Australia.

  • Weighs 103MT in air
  • Provides 150MT of uplift in seawater
  • 12.3m high
  • 6.44m long
