Infrastructure

FSRU, FSU and FLNG Infrastructure

Floating regasification, storage and liquefaction units, and how they differ from trading carriers.

Educational data

What it is

  • Floating units keep the containment technology of carriers but change the operational role to storage, regasification or liquefaction.
  • An FSRU regasifies, an FSU stores, and an FLNG liquefies offshore.

Where it is used

  • Import markets adding capacity, remote gas fields, and projects requiring phased infrastructure.

Key design characteristics

  • Mooring arrangements matched to site conditions.
  • Regasification or liquefaction topsides integrated with cargo systems.
  • Long station-keeping periods with limited or no transit time.

Benefits

  • Capacity can often be added on a different timeline than fixed onshore terminals.
  • Some units retain the ability to trade after conversion back to carrier service.

Operational considerations

  • Send-out capability, mooring and metocean limits are entirely project-specific.
  • Conversions inherit the containment and hull characteristics of the original vessel.
