LNG

LNG Import / Export

CH·IV International provides engineering services to owners and operators of LNG import and export facilities that encompass the entire lifecycle, from concept to operation. 

Small Scale LNG

Roots for the small-scale LNG (SSLNG) industry extend as far back as the 1960’s and 1970’s and includes LNG import, export, LNG liquefaction and Satellite LNG Facilities with capacities less than 1MTPA. CH·IV International provides engineering services to owners and operators of Small Scale LNG (SSLNG) facilities that encompass the entire lifecycle, from concept to operation.

LNG Peak-Shavers

LNG Peak-Shaving is one the most common ways to ensure a reliable and cost-effective supply of natural gas to domestic and power generation users during high demand periods. There are two types of Peak-Shaving facilities. While both types have on-site LNG storage tanks, one has on-site liquefaction facilities and the other lacks on-site liquefaction capabilities. Peak-Shavers with liquefaction facilities are able to take natural gas directly from pipelines, liquefy it, and store it for later use. Peak-Shavers without liquefaction facilities must rely on LNG tanker trucks to refuel their LNG storage tanks.  In either case, the stored LNG can be vaporized and sent-out to natural gas pipelines during high demand periods. CH·IV provides services to owners / operators of existing LNG Peak-Shaving Facilities as well as to owners / operators of proposed greenfield LNG Peak-Shaving facilities encompassing the entire lifecycle, from concept to operation. Since many existing Peak-Shaving facilities were designed in the 1960’s and 1970’s, their current performance may be significantly reduced due to changes in pipeline natural gas.  Therefore, in addition to the range of services listed below, CH·IV has developed a Cold Box Optimization Program that can be used to predict the performance of your plant and in turn increase LNG production, reduce fuel consumption, minimize risk of pipeline surcharges due to extended liquefaction season and feed forward monitoring.

Gas to Power

Many existing LNG Peak-Shaving facilities are being repurposed and several new greenfield LNG production and storage facilities are being developed to ensure a reliable and cost-effective supply of natural gas to the growing portfolio of natural gas fired power generation facilities. CH·IV International provides engineering services to owners and operators of LNG facilities in the Gas to Power market that encompass the entire lifecycle, from concept to operation.

Bunkering

LNG bunkering is the process of transferring liquefied natural gas to a ship for use as fuel.  The key advantage of LNG as a fuel is the significant reduction in pollutants from the more traditional fuels such as heavy fuel oil, marine diesel fuel (MDO) and marine gas oil (MGO). CH·IV International provides engineering services to owners and operators of LNG Bunkering facilities that encompass the entire lifecycle, from concept to operation.

Near Shore Marine, Offshore Marine and Floating Storage and Regasification Facilities (FSRU)

Near-shore LNG facilities include floating production, floating storage (FSO) and floating storage and regasification (FSRU) facilities.  FSO and FSRU facilities provide an opportunity to bring natural gas to market very quickly, including in remote locations or in locations where land-based real estate is limited.  While the FSRU options provides a fully integrated solution to store and vaporize LNG, the FSO option will require land-based (or barge mounted) LNG vaporization facilities. CH·IV International provides engineering services to owners and operators of near shore marine LNG facilities that encompass the entire lifecycle, from concept to operation.

LNG Vehicular Fuel

Natural gas powers an increasing number of vehicles and are a good choice for high-mileage, centrally fueled fleets because they can provide similar fuel range support for applications not involved in long-haul routes where fuel stations can become sparse. Two options are widely used – Liquefied Natural Gas (LNG) and Compressed Natural Gas (CNG).  For vehicles that travel long distances, LNG offers a greater energy density than CNG, meaning the fuel range is more comparable to conventional fuel. The advantages of natural gas as a transportation fuel include its domestic availability, widespread distribution infrastructure, and reduced greenhouse gas emissions over conventional gasoline and diesel fuels. CH·IV International provides engineering services to owners and operators of near shore marine LNG facilities that encompass the entire lifecycle, from concept to operation.
