Enhance Offshore Gas Processing With Modular Technology

Offshore gas processing creates unique challenges on fixed platforms and floating vessels. Space and weight constraints demand compact equipment. Vessel motion requires equipment engineered to maintain performance despite constant movement. Limited access means reliability is critical.

Honeywell UOP offers field-tested technologies designed to work together to remove water, contaminants and acid gases from natural gas streams. Our compact, lightweight systems are designed to fit the tight spaces of floating production storage and offloading (FPSO) and floating liquefied natural gas (FLNG) installations. From pretreatment to liquefaction support, our established adsorbents and membrane systems can adapt to demanding offshore conditions.

Compact footprints for space-constrained offshore platforms

Modular designs engineered for space-constrained offshore platforms help reduce equipment footprint while designed to maintain performance.

  • Reduced platform footprint helps reduce space requirements and can help increase usable deck space.
  • Lightweight construction helps minimize structural load.
  • Compact modular units can fit existing layouts.

Frequently Asked Questions About Offshore Gas Processing

Offshore gas processing feasibility depends on the interplay between reservoir characteristics, environmental constraints and economic factors.

Water depth will dictate platform type and installation costs, while feed gas composition determines required treating technologies and complexity. Distance from existing infrastructure influences whether pipeline export or floating LNG makes economic sense. Field size and production profile determine whether capital investment can be recovered over the field lifetime.

Integrating offshore gas processing systems involves balancing multiple competing constraints that don't exist onshore. Platform space is finite and must accommodate drilling, production, living quarters and safety systems alongside gas processing. Structural load limits on floating vessels restrict equipment weight. Power availability determines what can (and cannot) operate simultaneously.

Vessel motion requires stabilized designs that maintain performance despite constant movement. And limited maintenance access and high offshore modification costs drive integration decisions.

Honeywell UOP helps address these challenges with compact, lightweight gas processing systems deployed in offshore environments worldwide.

Offshore platforms face strict limits on power availability, cooling capacity and structural loads. Honeywell UOP gas processing solutions can help operators improve energy efficiency within those constraints.

  • UOP MOLSIV UI-900 adsorbent offers more capacity than standard sieves, helping reduce energy demand.
  • Membrane systems can reduce solvent heating and cooling loads through chemical-free separation.
  • Compact, modular designs can reduce weight while increasing power allocation and heat recovery.
