(LNG Regasification Vessel)

  • LNG-RV for EXMAR
    The World's first LNG-RV built for EXMAR
Dreams Come True...
The LNG RV is a vessel with combined functions of the conventional LNG carrier, which is designed mainly for transporting LNG, offshore mooring turret, and onboard regas facilities which connects regasified natural gas directly to a commercial pipeline trunk offshore, thereby eliminating the need for a land-based LNG receiving and regas facilities. Various technologies have been used for the building of the LNG RV including LNG vessel and terminal building, oil refining, gas FPSO, crude oil offloading and shuttle tanker mooring.

Background of LNG-RV

Removing the burden of massive investment costs and time for building a land-based LNG terminal and environmental destruction
Depending on the size, the construction of an LNG plant requires astronomical investment costs to build onshore receiving terminal and large-scale storage facilities where the massive LNG carrier docks and offlads the LNG.
The American company who became the first client ordering an LNG-RV from us and putting it to use, turned to an LNG-RV as an alternative after the company faced opposition to building an onshore LNG plant which could be environmentally destructive.
Geared up for smaller-scale supply
Excellent alternative to supply LNG on a smaller scale with lower investment costs
Free from the potential risks at onshore plants
The onshore LNG plants are exposed to terror threats and a minor accident which could lead to potentially catastrophic disaster impacts in densely populated areas.
Since LNG-RVs are typically located more than 100 miles away from the nearest land and directly connected to an offshore terminal to offload regasified natural gas, they are inherently safer from these risks.
Shorter construction time for building a LNG plant
It can appease public opinion cut the construction costs and time which could take 5 to 7 years from doing the feasibility study on an onshore LNG plant, convincing environmentalists, customer clearance, planning, and to actual building.

Regasification Procedure of LNG-RV

Regasification Procedure of LNG-RV

Submerged Turret Loading (STL) System

  • STL system equipment
  • The STL system connects the submerged turret in the bow area to an subsea terminal and transports them.

LNG-RV Regasification Facility Located on the Bow

A high pressure pump/vaporizer at the front hull and a water heating system that emits from the hull bottom
  • In LNG RV, 6 sets of high-pressure pumps and vaporizers are installed in the forward portion. The typical LNG regasification capacity of the LNG RV is 500 mmscfd, and 138,000 M3 of LNG can be converted to high pressure natural gas onboard within 5 to 6 days.
  • Water heating system:The heating medium of the vaporization is sea water. In most cases, the heating water is discharged to the open sea through the hull bottom called open mode.
