DUTCH gas shipping specialist firm Anthony Veder has ordered its first-ever liquefied natural gas tanker.
Managing director of Anthony Veder, Jan Valkier, told Lloyd’s List the vessel will be built by Polish shipyard Remontowa S.A. under an owner-supplier basis.
Mr Valkier said that the 7,500 cu m ship is unique because it will be able to transport other gases as well, including liquefied petroleum gas (LPG) and petrochemical gases.
The LNG will be transported at minus 163 degrees centigrade and the ship will mainly be deployed for regional distribution.

Thanks to our expertise in LNGC production, we have become one of the foremost leaders in the world's shipbuilding industry. Our LNG vessels, with the proven reliability of the GTT membrane containment system, boast low construction costs and less fuel consumption, and operate at the highest speed among ships of the same class. Owners can also take advantage of their exceptional maneuverability and ease of maintenance. Equipped with the in-house-developed Integrated Automation System, operators of our LNG vessels are able to control and monitor a variety of tasks, such as loading and unloading, navigating, and ensuring safety. Also, the LNG simulator can further enhance safety by providing forecasts of navigational risk factors and LNG status. DSME has its own manufacturing shops for cargo tank insulation boxes and INVAR steel processing shops. We take great pride in having independently developed and designed all of the automated LNG production facilities, as we believe it leads to lower construction costs and higher quality.
In 2005, DSME successfully built and delivered the world's first LNG-RV (Regasification Vessel), and became the first shipbuilder to have an annual production capacity of 14 LNGCs. In the same year, DSME's next-generation-210,000 m3 LNGC was selected as the world standard for that class, and the fact that the company won 9 out of the total 16 orders for LNGCs placed worldwide in that year is yet another testimony to its incomparable strength in technology and production.

For gas- and chemical transportation the inert gas needs to be of high purity. For many applications, oxygen levels of 0.5% or even 0.1% are required, in combination with a water dew-point of about -45 °C and sometimes lower
(-65 °C). Also here, the burner is the heart of the system as the inert gas needs to be absolutely soot free in the first place. This is achieved with the Ultramizing® Combustion system. When the gas leaves the generator, it has the right composition, but it is saturated with 100% water and has to be dried. The drying process takes place in two steps. In the first step of the refrigerant cooler, the gas temperature is lowered to 5 °C which results in condensation of a great quantity of water. In the second stage the inert gas is dehumidified further in a double vessel type drying-unit using activated alumina or adsorbent. The whole process operates under a pressure of about 0.3 bar(g).
