South Korean shipbuilder Daewoo Shipbuilding Marine Engineering (DSME) completed the construction of the first Arctic LNG carrier, the Christophe de Margerie. 

According to the shipbuilder’s statement, the vessel, named after former Total’s CEO who died in a tragic plane crash at the end of 2014, is scheduled to set out for its sea trials in the Arctic sea to test its icebreaking capabilities during the week, after 30 months of construction.

Following the completion of sea trials, the 172,600-cbm LNG carrier will be delivered to its owner, Sovcomflot, at the end of January.

The Arc7 ice class Christophe de Margerie will be able to navigate in ice fields of up to 2.1 meters thick as its bow and stern are covered with 70 millimeters of steel plates capable of withstanding temperatures of -52°C.

DSME has further 14 Arctic LNG carrier on order, all contracted to serve the Yamal LNG project in Russia.

Christophe de Margerie is the only vessel ordered by Sovcomflot while the remaining 14 vessels are owned by MOL (three) Teekay (six) and Dynagas (five). Deliveries of the remaining newbuilds are scheduled over the next four years.

Liquefied Natural Gas


Natural gas is the most climate friendly of the fossil fuels releasing less CO2 than oil based products such as diesel.

Natural gas is the world’s third most important energy source after oil and coal. It occurs naturally deep underneath the earth’s crust in many places around the world. Natural gas currently represents a quarter of the global energy supply.

Natural gas is used in industry, in power plants, in district heating and in sea and overland transport. Throughout Europe, natural gas has traditionally been regarded as a form of green energy.

There are many reasons to take an interest in natural gas. It has major advantages over other fossil-based energy sources – not least the fact that natural gas gives off fewer undesirable emissions. But also because natural gas is more efficient and kinder to the environment than the other fossil fuels which are currently used in industry, shipping and overland transport.

Natural gas is converted to LNG by harnessing innovative cryogenic technologies that make it available both for worldwide transport as well as for local markets. This conversion can also contribute to increased use of biogas. The conversion of natural gas into liquid is achieved through refrigeration by cooling natural gas to -162°C.

The resulting condensate is known as Liquefied Natural Gas (LNG). Liquefaction reduces the volume by about 600 times, making it more economical to transport between continents in specially designed LNG carriers. Liquefied natural gas, or LNG, is natural gas in its liquid form. It is the cleanest burning fossil fuel as it produces less emissions and pollutants than either coal or oil.

What’s the difference between CNG, LNG, LPG and Hydrogen?


The following is a brief summary highlighting the main differences of these fuels.  Much more comprehensive details of the fuel properties and compositions is available from other web sources and online databases.

Compressed Natural Gas or CNG is stored on the vehicle in high-pressure tanks – 20 to 25 MPa (200 to 250 bar, or 3,000 to 3,600 psi).  Natural gas consists mostly of methane and is drawn from gas wells or in conjunction with crude oil production.  As delivered through the pipeline system, it also contains hydrocarbons such as ethane and propane as well as other gases such as nitrogen, helium, carbon dioxide, sulphur compounds, and water vapour.  A sulphur-based odourant is normally added to CNG to facilitate leak detection.  Natural gas is lighter than air and thus will normally dissipate in the case of a leak, giving it a significant safety advantage over gasoline or LPG.

Liquefied Natural Gas or LNG is natural gas stored as a super-cooled (cryogenic) liquid.  The temperature required to condense natural gas depends on its precise composition, but it is typically between -120 and -170°C (-184 and –274°F).  The advantage of LNG is that it offers an energy density comparable to petrol and diesel fuels, extending range and reducing refuelling frequency.

The disadvantage, however, is the high cost of cryogenic storage on vehicles and the major infrastructure requirement of LNG dispensing stations, production plants and transportation facilities.  LNG has begun to find its place in heavy-duty applications in places like the US, Japan, the UK and some countries in Europe.  For many developing nations, this is currently not a practical option.

Liquefied Petroleum Gas or LPG (also called Autogas) consists mainly of propane, propylene, butane, and butylene in various mixtures.  It is produced as a by-product of natural gas processing and petroleum refining.  The components of LPG are gases at normal temperatures and pressures.  One challenge with LPG is that it can vary widely in composition, leading to variable engine performance and cold starting performance.  At normal temperatures and pressures, LPG will evaporate. Because of this, LPG is stored in pressurised steel bottles.  Unlike natural gas, LPG is heavier than air, and thus will flow along floors and tend to settle in low spots, such as basements.  Such accumulations can cause explosion hazards, and are the reason that LPG fuelled vehicles are prohibited from indoor parkades in many jurisdictions.

Hydrogen or H2 gas is highly flammable and will burn at concentrations as low as 4% H2 in air.  For automotive applications, hydrogen is generally used in two forms: internal combustion or fuel cell conversion.  In combustion, it is essentially burned as conventional gaseous fuels are, whereas a fuel cell uses the hydrogen to generate electricity that in turn is used to power electric motors on the vehicle.  Hydrogen gas must be produced and is therefore is an energy storage medium, not an energy source.  The energy used to produce it usually comes from a more conventional source.  Hydrogen holds the promise of very low vehicle emissions and flexible energy storage; however, many believe the technical challenges required to realize these benefits may delay hydrogen’s widespread implementation for several decades.

Hydrogen can be obtained through various thermochemical methods utilizing methane (natural gas), coal, liquified petroleum gas, or biomass (biomass gasification), from electrolysis of water, or by a process called thermolysis.  Each of these methods poses its own challenges.

vacuum insulated piping -New LNG Refueling Station for Inland Waterway Barges and HD Trucks at Doesburg

LNG Refueling StationCryonorm Systems, a Dutch company specialising in the development, design and manufacture of cryogenic vaporizers, small scale systems and plants for LNG, has completed the building of a Liquefied Natural Gas (LNG) filling station that will be used for the LNG fueling of inland waterway barges and trucks.

The LNG filling station has been built for logistics provider Royal Rotra and is located near the new Rotra container terminal in Doesburg in the eastern Netherlands. Rotra is currently using 9 trucks fueled by liquefied natural gas and they are all fueled at the LNG station.

By opening the station Rotra is stimulating sustainable mobilization of the multimodal transport chain with the use of LNG as an alternative and clean fuel. This innovation is supported by the European Union with funding from the TEN-T Program, the company said in a press release.

LNG Refueling StationThis year Rotra expects to drive more than 1.000.000 kilometers on LNG. The company recently took delivery of four new trucks equipped with Euro 6 engines. They have two stainless steel fuel tanks with a total storage of 350 liters, which are mounted on the Scania P340 tractor chassis, and their reduced noise allows for quieter urban operations.

The construction of the terminal is in its last phase and will be officially opened in April 2016. During that ceremony also the LNG filling station will be officially opened. The station is fitted with two dispensers, one for trucks and one for inland water way vessels. LNG bunkering point for these vessels is installed on the quay connected with vacuum insulated piping.
