Excelerate Energy has developed both the Gateway and GasPort offshore regasification solutions for the receipt of LNG.

Gateways

Gateways, such as Excelerate Energy's Gulf Gateway Deepwater Port and Northeast Gateway Deepwater Port, consist of:

  one or more submerged turret loading buoys that connect to the Energy
  Bridge Regasification Vessel (EBRV^®) and serve as both a mooring for the
  vessel and a conduit for the discharge of natural gas;
  chains, wire rope, and anchors used to secure each of the buoys to
  the seabed;
  a flexible riser designed to connect the buoy to a seabed pipeline end
  manifold (PLEM) – allowing tie-in to a subsea pipeline;
  a subsea PLEM that incorporates necessary control instrumentation and
  related valving; and,
  an interconnecting subsea pipeline to tie into downstream delivery
  infrastructure.

In general, a Gateway will be located offshore, typically in excess of 10 miles.

GasPorts

GasPorts, such as Excelerate Energy’s Teesside GasPort, are dockside applications of the Energy Bridge technology. Using the dockside delivery method, an EBRV will arrive at a GasPort and a shore-mounted high-pressure arm will connect to the vessel’s gas manifold. Natural gas vaporized onboard will be delivered from the EBRV at pipeline pressure. Effectively, this allows an EBRV to function as a highly flexible LNG receiving terminal, and the low cost of construction of a GasPort (typically one-tenth that of a conventional LNG receiving terminal) allows for short term or seasonal service, in addition to baseload deliveries.

As an enhancement, a GasPort may be designed to allow for “across-the-dock” transfer of LNG such that a conventional LNG carrier can deliver directly into the EBRV while at the dock to ensure uninterrupted flow of natural gas.
