How it works

Gas in. LNG out. On one hull.

  1. 01

    Gas reception

    Feed gas arrives by subsea pipeline; inlet treatment removes condensate and water.

  2. 02

    Pre-treatment

    Acid gas, water and mercury are removed to protect the cryogenic plant.

  3. 03

    Liquefaction

    A mixed-refrigerant cycle cools the gas to −162 °C, in modular trains.

  4. 04

    Storage & offloading

    Stored on board and offloaded side-by-side to LNG carriers.

Standard design

Scale by trains, not by re-engineering.

About the Nguya project

Product portfolio

SMR

Single mixed refrigerant

Fewer equipment items and a compact, light footprint, for fast-track and space-constrained projects. Proven in floating service.

  1. 0.6MTPAFEED + EPC
  2. 1.2MTPAFEED + EPC
  3. 1.5MTPAFEED
  4. 2.0MTPAFEED

DMR

Dual mixed refrigerant

Two independent refrigerant cycles, staged high and low, for energy-efficient liquefaction at larger scale.

  1. 2.5MTPABaseline
  2. 3.0MTPAScalable
  3. 4.0MTPAScalable
  4. 5.0MTPAScalable
  5. 6.0+MTPAProject-specific

Final configuration is set in FEED, from the gas resource, site conditions and project economics.

Why Wison FLNG

Proven offshore. Standard by design.

  1. 01

    EPCIC turnkey

    Engineering to commissioning, one team — faster first LNG.

  2. 02

    World-first barge FLNG

    Tango FLNG was the first barge-type FLNG in commercial production.

  3. 03

    Proven offshore

    Nguya FLNG delivered its first LNG cargo off the Republic of the Congo in February 2026.

  4. 04

    Standardized & scalable

    Standard hulls from 0.6 to 6.0+ MTPA.

  5. 05

    Add trains to grow

    Capacity grows by adding trains, not redesigning.

  6. 06

    Redeployable

    One floating asset instead of an onshore plant.
