Gas Carriers

The vital link in LNG infrastructure

Increasing environmental regulations have brought LNG to the forefront as a clean fuel and a step in the right direction towards reducing CO₂ emissions of shipping. While safety remains first and foremost for gas carriers, a lot of attention is paid to maintaining the balance between environmental efficiency and manageable operation costs, which puts a premium on high-reliability designs. Vessels are being built to accommodate innovative technologies, and the potential for untapped gas resources in the Arctic has prompted a wave of interest in LNG tankers equipped to traverse polar waters.

How we support you

Bureau Veritas has a long history in gas carriers: we were the first classification society to create dedicated Rules for LNG carriers. Our expertise in gas carriers transporting both LPG and LNG, as well as their containment systems allows us to assess vessels of all types and sizes.

Approval of cargo containment systems

Bureau Veritas has in-depth knowledge of gas cargo containment systems, having worked on numerous concept approvals for manufacturers. This expertise makes Bureau Veritas the primary partner for containment systems designers and shipyards.

What is boil-off in gas tankers and how can it be reduced?

LNG carrier transport liquefied natural gas at a temperature close to vaporization (-163°C). This means that, despite tank insulation, even a small amount of heat will result in slight evaporation of the cargo, which is called “boil-off”. Bureau Veritas analyzes and issues approvals for containment systems that minimize boil-off, resulting in improved performance.

ADDRESSING SLOSHING RISK

Sloshing may present a challenge for gas carrying vessels as flexible cargo operations and floating storage regasification projects become more common. Our advanced Hydrofoam and OpenFoam CFD software allow Bureau Veritas to precisely simulate the hydrodynamic behavior of a ship and calculate the liquid motion within the cargo tanks.

Pioneering LNG bunkering

LNG bunkering vessels are crucial to the widespread adoption of LNG as a marine fuel. Bureau Veritas was among the first classification societies to publish dedicated Rules for LNG bunkering, and classed the first-ever dedicated newbuild ship. We are the market leader in LNG bunkering vessels, including ships with a gas carrying capacity of up to 18,600 m³ and containment systems ranging from pressurized tanks to membrane tanks.
