Optimize FSRU and FLNG projects with APL’s versatile mooring, loading, and offloading solutions

Description

APL has developed cost-effective mooring and gas transfer technologies for both offshore floating storage and regasification unit (FSRU) terminals and floating liquified natural gas (FLNG) production vessels. Based on the proven Submerged Turret Loading (STL™) technology, APL deployed the world's first offshore liquified natural gas (LNG) terminal in 2005 and has since developed a suite of related technologies. Our systems are suitable for shallow and deep-water applications and can moor your floater in water depths ranging from 20 to 3000 m.

Gas import solutions (FSRU)

A number of technologies have been developed to moor an FSRU and transfer gas to powerplants or to gas grids onshore. Our turret mooring systems keep the FSRU on station while receiving LNG from incoming LNG carriers. The systems, which typically replace more costly jetty and breakwater solutions, are designed to accommodate shallow-water applications, providing pipeline capital-expenditure savings and lower installation costs.

LNG loading and offloading features

  • Cost-effective energy import
  • FSRUs faster to deploy versus costly onshore receiving facility
  • No need for jetties
  • Plug and play system allows for easy relocation
  • Reliable in both benign and harsh environments with quick disconnection functions

Gas processing and export solutions (FLNG)

We provide a number of turret mooring technologies suited to moor FLNG units offshore. These are well-proven solutions and suitable for a variety of water depths, metocean data and gas flow/pressure regimes.

FLNG features

  • Enables schedule decoupling of the offshore installation and shipyard work
  • Can be designed for permanent or disconnectable service
  • Proven and reliable in both benign and harsh environments
  • No need for jetties
  • High safety due to its offshore location

Power barges for power/energy transfer

With a high-voltage power swivel included in our turret mooring systems, APL can provide solutions for power barges/floaters, transferring power rather than gas to shore.

Carbon capture and storage

As part of our extended green energy initiative, we have developed turret mooring systems that allow project owners to export and inject CO2 into the reservoir offshore. Our systems will allow transfer of CO2 from a CO2 carrier to a floating or fixed structure (which, in turn, injects the CO2 into the reservoir) as well as direct injection from the CO2 carrier.
