Subsea LNG Cryogenic Pipeline

Subsea LNG Cryogenic Pipeline

Abstract

The Fluor LNG pipeline technology uses a highly-efficient thermal nano-porous insulation in the annular space, between the inner and outer pipes, and this material is kept in an ambient pressure environment. The nano-porous insulation is hydro-phobic, in that the pour spaces are smaller than the molecules of water; therefore, the insulation does not absorb water. In addition, the insulation does not degrade in the presence of water or moisture, an important consideration for thermal efficiency and for operational maintenance. One novelty of the present Fluor LNG pipeline technology is the application of high-strength 9% Ni alloy steel pipe, metallic bulkheads and spaces to cryogenic product pipelines. As a result, the pipeline bundle configuration is a structural element, which addresses the thermal contraction and expansion loads, without resorting to expansion bellows or ultra-low thermal contraction alloys.

Client Benefits

Fluor's subsea LNG pipeline technology focuses on providing the following advantages to Fluor's offshore clients:

  • Lower costs to build
  • Better reliability
  • Resistant to water ingress
  • Better life cycle costs
  • Taking advantage of the inherent cold energy in LNG, while maintaining robust plant operations with minimum impact on the environment
  • Use on offshore, onshore, or terminal applications

Fluor’s LNG technologies make the LNG regasification facility more flexible, competitive and energy efficient, while allowing the facility to meet even the most stringent sales gas specifications using any LNG presently traded in world markets.
