DNV GL believes using sensors to measure LNG parameters in real-time will improve price transparency in liquefied natural gas (LNG) bunkering, which has traditionally relied on mass alone rather than mass and energy content.
The international accredited registrar and classification society made the above statement on Wednesday (14 March) when opening a liquefied natural gas (LNG) testing centre in Groningen, the Netherlands.
New sensor technology used at the centre will be able to rapidly identify the composition of LNG, says Johan Holstein, Head of gas testing and analysis at DNV GL – Oil & Gas.
“The current accredited technology, gas chromatography, can take 3-5 minutes to show the composition of LNG,” Holstein explained. “Sensors can give an answer in a second.”
The impact of changing LNG composition on engine performance can also be studied at the Groningen site.
Engine developers can optimise ignition patterns and compression ratios depending on the LNG composition, for example, and the facility will allow OEMs to perform compliance tests ranging from automotive engines of around 10hp to off-road and marine engines of around 500kW.
The facility is the first of its kind with a capacity compatible for the downstream sector. Its capacity is up to 250kg of liquefied gas and boasts a heat exchanger that allows the temperature of the LNG – and therefore its boil-off – to be precisely regulated.
“The 2017 DNV GL Energy Transition Outlook report predicts that LNG and LPG will account for 32% of total shipping energy use in terms of technology and fuel uptake, so I believe DNV GL’s continuing investment in facilities, recommended practices and online tools is timely and builds on our established expertise in downstream LNG,” says Ben Oudman, Regional Manager – Continental Europe, Eurasia, Middle East, India and Africa, DNV GL – Oil & Gas.
“Our aim is to support the industry adoption of LNG in an efficient, reliable and safe way.”
For LNG fuel quality testing, DNV GL has engaged in a strategic partnership with Veritas Petroleum Services (VPS) to further develop procedures and practices to ascertain and monitor LNG quality.
DNV GL and VPS aim to develop a set of validated tools and measurement methods to provide the LNG industry with accurate, reliable and cost-efficient tools to help break down the perceived barriers to LNG adoption.

Fifteen incidents of misappropriation of Shell gasoil worth USD 10,4 million went undetected by Shell between 2016 to 2017 due to Muhammad Ali Bin Muhammad Nor’s involvement, learned Manifold Times.
ISO delegates represented seven countries and were in Singapore to attend a three-day meeting of ISO WG13 to develop two new ISO bunkering standards, learns Singapore bunkering publication Manifold Times.
Cai Zhi Zhong received a total of about USD 1.3m to USD 1.6m, of which he saved a portion and spent the rest, including on property, cars and watches, according to court documents obtained by Manifold Times.
‘MFMs will continue to have a place within the bunkering sector even when the shipping industry continues to adopt new types of marine fuels, such as LNG, biofuel, methanol, ammonia and hydrogen,’ states spokesman.
Current ISO 8217 bunker fuel standard not comprehensive enough for biofuels; National Mirror Committee working with local players to develop more comprehensive biofuels standard for Singapore, says Capt. Rahul.
‘There are some important differences between VLSFO and biofuels, and as a result, parties should consider whether additional changes should be made to biofuel bunker contracts,’ says Paul Collier.
