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 can moor your floater in water depths ranging from 66 to 9,843 ft (20 to 3000 m).

Gas import solutions (FSRU)

Ship-to-shore: A number of technologies have been developed to moor an FRSU and transfer gas to powerplants or a gas grid onshore. Our turret mooring systems keeps the FSRU on station while transferring and 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.

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.
Ship-to-ship: On the back of our traditional Stern Discharge System (SDS) for oil, we have developed a tandem offloading system for LNG that connects the bow of a shuttle LNG carrier to the stern of an FLNG production vessel. Tandem mooring of two vessels is a proven solution and is very safe and reliable in harsh weather conditions.

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.

LNG loading and offloading features

  • Cost-effective energy import
  • FSRUs faster to deploy versus costly onshore receiving facility
  • No need for jetties
  • Reliable in both benign and harsh environments
  • Particularly suited for shallow-water applications

Production of FLNG features

  • Enables schedule decoupling between the offshore installation and shipyard work (FLNG unit, conversion, or new build)
  • Designed for disconnect service or for permanent mooring throughout the field life
  • Reliable in both benign and harsh environments
