DNV presents a new system of rules for LNG


The maritime classification company DNV has developed new class rules and a class notation “gas fuelled LPG” for using liquefied petroleum gas (LPG) as fuel in anticipation of growing industry interest.

 

Except for liquefied natural gas, currently all gases and low-flashpoint fuels are subject to the ‘alternative design approach’, which means that they may be used if the safety, reliability and dependability of the systems can be shown to be equivalent to those achieved by new and comparable conventionally fuelled main and auxiliary machinery.

 

This can be a time-consuming and costly process and may impede the uptake and expansion of lower emission alternative fuels. “With the new rules and class notation, we want to offer owners interested in LPG a straightforward path towards compliance with the alternative design approach mandated by the IGF Code,” said Geir Dugstad, director of ship classification & technical director at DNV GL – maritime.

 

The rules and notation are based on DNV GL’s rules for ships using LNG as fuel but account for the differences in properties and phases between LPG and LNG. (fd)
