DNV GL stamps Methanol powered Tanker

The worldwide first with Methanol powered vessels will navigate with DNV GL Class the classification society announced recently.

The four 50.000 tdw tanker have been ordered by the Swedish shipping company Marinvest and the Norwegian company Westfal-Larsen at the Korean shipyard Hyundai Mipo Dockyards. The classification follows according the DNV GL regulation for fuels with low flashpoint. The very first tank ship shall be delivered by 2016.
DNV GL says the sulfur free fuel with low flashpoint (Low Flashpoint, LFL) of about twelve degrees Celsius becomes more and more attractive for the maritime industry, because this fuel fulfills the upcoming SOx-limit values in the emission control areas.
The vessels, which will carry the additional DNV GL mark LFL FUELLED, feature a secondary bunker system as well as an automatically leakage warning system with shot-off function and flame protection systems. Further building safety measures include the position of the tanks and fuel pipes.

According to the classification society DNV GL, they are the first who have published regulations for LFL and sees with Methanol an alternative towards common fuel which produce some sulfur and nitrogen emissions. Ship engines can be retrofitted for the use of Methanol fuel.The engines will run on a blend of 95% methanol and 5% diesel fuel.
