US Coast Guard adopts LNG bunker rule based on DNV GL's best practice

THE US Coast Guard (USCG) has published two policy letters on LNG bunkering, personnel training and waterfront facilities based on classification society DNV GL's paper, "Development and Operation of LNG Bunkering Facilities".

Since US ports do not have LNG liquefaction and storage facilities yet, ships will have to rely on small-scale bunkering for the time being, reports the American Journal of Transportation.

In 2013, the class society developed recommended practice for LNG infrastructure while waiting for the appearance of ISO 18683 workgroup documents on systems and installations for supply of LNG as ship fuel.

"DNV GL is already doing everything the USCG could hope for when it comes to LNG as fuel," Ken Smith, general engineer at the USCG Office of Vessels' and Facilities' Operating Standards.

Tony Teo, Technology and Business director North America, explains that simultaneous operations like loading/unloading of cargo or passenger movements at the terminal during bunkering operations require special attention. 

"We recommend carrying out a full quantitative risk assessment to demonstrate that overall safety targets are met, evaluate and select safeguards and risk reducing measures," he said.

Most of the LNG-fuelled ships and a large number of LNG tankers sailing today are built to DNV GL's classification rules.
