Natural Gas Supply & Delivery

VOLCO Power works with international gas companies to provide a cost-effective and reliable supply of Natural Gas for short-term or long-term projects. As we recognise that each project is unique, our direct network of international gas companies allows us to custom-design the full supply chain for each project, ensuring the most cost-effective and reliable source of delivery.

Down Stream Gas Supply

  • Processing of Gas from supply source for transportation
  • Transportation (road, rail, pipeline)
  • Delivery to Client
  • Onsite processing in order to receive required specifications (regasification, compression)
  • Industrial conversions from current fuels to Natural Gas

Full Supply Chain “Virtual Pipeline”

Midstream:

  • Shipping
  • Gas terminal
    • Floating Storage & Regasification Unit (FSRU)
    • Floating Storage (Barge)
    • Land Based Storage

Downstream:

  • Processing of Gas from supply source for transportation
  • Transportation (road, rail, pipeline)
  • Delivery to Client
  • Onsite processing in order to receive required specifications (regasification, compression)
  • Industrial conversions from current fuels to Natural Gas

In order to achieve a competitive pricing structure for delivered LNG, each project will require a full end to end solution “Virtual Pipeline” comprising of a competitive FOB gas price from an LNG terminal closest to the project, shipping of the gas to the country and the necessary infrastructure for regasification and offloading of the gas at port or off shore.

Flexible arrangements with international partners and associates allows us to design a “Virtual Pipeline” that extends from gas supply to shipping to regasification and then final delivery.

Our network of international companies that enable us to provide the most cost effective and reliable gas supply chain include:

  • Well head operators
  • Pipeline operators
  • Liquefaction plant owners & operators
  • Private and state owned gas companies
  • Shipping and logistics companies
  • Storage and regasification companies & operators
  • Local & international distribution companies

The Well:

Piped gas will be provided to the LNG terminal. The raw feed gas supply arriving must be clean and dry before liquefaction can take place. It is scrubbed of hydrocarbon liquids and dirt and treated to remove trace amounts of two common natural gas contaminants: hydrogen sulfide and carbon dioxide. Next, the gas is cooled to allow water to condense and then further dehydrated to remove even small amounts of water vapor.

Liquefaction:

The clean and dry gas may then be filtered before liquefaction begins. It is important that the gas consist primarily of methane with only small amounts of light hydrocarbons to ensure an efficient process. Liquefaction takes place through cooling of the gas using heat exchangers. In these vessels, gas circulating through aluminum tube coils is exposed to a compressed hydrocarbon-nitrogen refrigerant. Heat transfer is accomplished as the refrigerant vaporizes, cooling the gas in the tubes before it returns to the compressor. The liquefied natural gas is pumped to an insulated storage tank where it remains until it can be loaded onto a tanker.

Shipping:

LNG from the terminal is loaded onto an LNG vessel that has specialized cryogenic handling equipment and cargo containment systems that enable the vessel to carry Liquefied Natural Gas that is cooled to -161°C. Because LNG occupies about 1/600 the space of methane in its gaseous form, it can be transported in large quantities in efficient, purpose built tanker ships or in portable tanks. Transportation accounts for 10 to 30 percent of the cost of the LNG value chain. Therefore it would make sense that part of the design criteria for each project, the carrier ships are design engineered for each project and contracted by a commercial shipping company to supply a full end to end LNG delivery solution.

Regasification:

There are several different options for Regasification of LNG that can be used and will be project specific. The design engineering for the optimal solution will depend on met ocean conditions at site and consist of the following:

  • Floating Regas and Storage Units (FSRU’s)
  • Land based terminals
  • Floating Barge
  • Off shore storage and regas

Off-Takers:

  • Power generation projects
  • Industrial consumers of Natural Gas
