DNV GL has issued approval in principle (AIP ) for a liquefied natural gas (LNG) fuelled very large crude carrier (VLCC) design by China’s Dalian Shipbuilding Industry Company (DSIC).

The dual fuel design complies with the gas fuelled notation as stated in the DNV GL rules for the classification of ships and also the recently adopted IGF Code.

The design is expected to offer greater flexibility in bunkering options, while minimising the emission of particulates, SOx, as well as CO2 emissions.

In gas fuel mode, the design achieves a 30% reduction factor to comply with Phase III of the Energy Efficiency Design Index (Eedi ) regulations, stated DNV GL.

“The LNG fuel tanks will enable the vessel to perform a round-trip from the Middle East to the US without refuelling.”

Featuring type C fuel tanks to minimise the impact on the overall layout, the new design is expected to provide the vessel with the capacity to handle cargo in accordance with conventional designs.

According to the company, the LNG fuel tanks will enable the vessel to perform a round-trip from the Middle East to the US without refuelling.

DNV GL vice-president and regional manager in Greater China Torgeir Sterri said: “This AIP is another step toward the more widespread adoption of LNG as a fuel for shipping.

“The emissions and efficiency benefits of LNG mean it is almost sure to become an important part of the fuel mix over the next few years. We have seen its adoption in many sectors already and now with this AIP, the world’s first for a VLCC, this major shipping sector could see its first LNG-fuelled vessel soon.”

In addition, the classification society also granted AIP for DSIC’s new DSJ-500 jack-up rig design for drilling to 500ft in depth.
