Classification society DNV GL and Keppel Marine and Deepwater Technology (KMDTech), a subsidiary of Keppel Offshore & Marine (Keppel O&M), on Friday (12 April) announced they have signed a framework agreement to boost the uptake of liquefied natural gas (LNG) as ship fuel.

The agreement covers potential newbuilding projects including LNG bunker vessels, small-scale LNG carriers and floating storage regasification units (FSRUs), as well as LNG related assets employing battery and hybrid technologies.

“The signing of this agreement signifies another milestone in the close partnership between DNV GL as the leading classification society for LNG ships and offshore assets, and Keppel Offshore & Marine, a world leader in conversion projects for Floating Storage Regasification Units (FSRU) and floating liquefied natural gas vessels (FLNGV) as well as for newbuilding of small-scale LNG carriers and LNG bunker vessels,” said Cristina Saenz de Santa Maria, DNV GL’s Regional Manager for South East Asia, Pacific and India.

Abu Bakar Mohd Nor, Managing Director of Keppel O&M for Gas and Specialised Vessels, said: “We are pleased to partner with DNV GL in developing a suite of LNG related vessels that are ready to meet the needs of the market as the adoption of LNG as ship fuel increases.”

“Working with DNV GL enables us to demonstrate the strength of our vessel designs and the viability of LNG for ship owners. We have a strong track record in delivering LNG solutions including the first FLNGV conversion as well as LNG fuelled vessels.”

As the first delivery in the agreement, DNV GL will issue Approval in Principle (AiP) certificates for two LNG bunker vessel designs from KMDTech: 
 

  • a 7,500 cbm small-scale LNG carrier with bunkering capabilities and 
  • a 7,500 cbm small-scale LNG carrier with bunkering capabilities and hybrid battery propulsion.

The LNG carriers are each designed to carry up to 7,500 cubic meters of LNG in Type C-tanks. An optimised deck arrangement for the modular LNG gas supply, filling and safety systems increases the cargo capacity and efficiency of the vessels. They are equipped with engines that can run on both diesel and LNG, and will also have a class notation for bunkering which enables the provision of LNG bunkering services if required.

In light of the upcoming IMO 2020 SOx regulations, LNG as marine fuel is viewed as one of the most viable options for deep-sea shipping. DNV GL’s Maritime Forecast to 2050, part of the research behind the DNV GL Energy Transition Outlook 2018, projects that more than 10 per cent of the world’s shipping fleet will be powered by LNG by 2030, compared to less than 0.3 per cent in 2019. The report anticipates that LNG powered vessels will make up 23 per cent of the world’s fleet by 2050.

In order to support this growth, an upgrade of LNG bunkering infrastructure is needed.

“One of the objectives of our collaboration with Keppel is to facilitate the increased supply of LNG bunkering infrastructure by being future ready through design approvals of different sizes of LNG bunker vessels, and LNG-related assets such as small-scale LNG carriers and FSRU,” said Johan Peter Tutturen, Business Director Gas Carriers in DNV GL.

The collaboration is also intended to further advance asset design by optimising machinery and systems configuration to increase fuel efficiency, using advance simulation tools such as DNV GL’s COSSMOS.

Additionally, the parties will work together to establish round table discussions involving all stakeholders in the LNG-as-fuel value chain, including gas and LNG bunker suppliers, designers, shipbuilders, shipowners and operators, in an effort to increase the uptake in demand for LNG bunkering in Singapore and beyond.

The design and engineering collaborative office will be located at KMDTech Singapore, with Keppel O&M’s yards to undertake the project execution.

Erik Thun takes delivery of LNG dual-fuel tanker “Thun Vettern”

Shipping firm Erik Thun on Monday (24 June) said it has taken delivery of Thun Vettern, a 17,999-dwt vessel, which was built by China Merchants Jinling Shipyard in Yangzhou.

The vessel is an upgraded version of the sister Thun Venern. Thun Vettern is the latest contribution to the “Vinga-series”, all trading within the Gothia Tanker Alliance. The Thun Vettern is the newest and latest edition to the Vinga-series and she has ice class 1A. 

The vessels in the Vinga-series all have dual-fuel capability, run on LNG/LBG or gasoil and are fully equipped for shore power connection when available in ports.

They are designed with a battery hybrid solution and several innovative features that reduce fuel and energy consumption, resulting in extensively lowered emissions of CO2, sulphur oxide, nitrogen oxide and hazardous particles. 

The firm said the ships have scored the best Energy Efficiency Design Index or EEDI value in their segment globally, meaning that they are the most energy efficient vessels according to the International Maritime Organization (IMO). 

The Vinga-series is designed for the intense and demanding trade in the North Sea and Scandinavia, well suited to meet the growing European demand for biofuels and renewable feedstocks.

Erik Thun´s close partner Furetank will technically and commercially manage the new vessel which upon delivery will enter into the Gothia Tanker Alliance network.

“Sustainability work has always been and will be a focus ahead for Erik Thun. To take delivery of a resource efficient, top performing product tanker like Thun Vettern, and further deepen our good and long-term co-operation with Furetank is a great example of our vision to be a sustainable Swedish partner over generations,” said Johan Källsson, Managing Director at Erik Thun AB.

Wärtsilä on LNG bunker fuel: Expert answers to 17 important questions

Firm gives an expert overview on top questions on LNG bunker fuel including if LNG is a future fuel and what does LNG being a transition fuel means.

RESIZED Chris Pagan

Technology group Wärtsilä on Wednesday (19 June) gave an expert overview on top 17 questions related to LNG bunker fuel in this insight article including if LNG is a future fuel: 

Your choice of fuel affects both your profitability and your vessel’s environmental compliance. Liquefied natural gas (LNG) is a safe and cost-effective fuel that reduces greenhouse gas emissions and other harmful pollutants. LNG is playing a key role as a transition fuel and is widely seen as the first step towards decarbonising the maritime industry.

Switching to LNG as fuel for ship propulsion requires investment but can save you fuel costs, increase your profitability and reduce compliance risks. The expert answers to these 17 questions will tell you what you need to know about LNG as an alternative fuel for shipping.

What is LNG?

LNG is natural gas that has been cooled to -162°C (-260°F), turning it into a clear, odourless liquid that is easy to ship and store. LNG is typically 85–95% methane, which contains less carbon than other forms of fossil fuels. It is a compact, efficient form of energy that is ideal for ship propulsion.

What is LNG used for?

LNG is primarily used as a clean-burning energy source. It is used for electricity generation, heating, cooking, and as a transportation fuel. LNG is also used as a raw material for products like fertilisers and plastics.

In the shipping industry, LNG as fuel is used for ship propulsion, auxiliary power generation and other onboard energy needs. LNG as an alternative fuel for shipping has gained wide popularity due to its clean-burning properties and potential to help meet stricter emissions regulations.

What are the sources of LNG as fuel for ships? What is bioLNG?

LNG as fuel for ships is produced from natural gas extracted from underground reserves, including both onshore and offshore gas fields.

BioLNG is LNG produced from biogas, which is generated from organic waste like food scraps, agricultural waste, manure and sewage sludge. BioLNG is considered a renewable fuel and can further reduce the carbon footprint of ships using LNG fuel systems.

 Is LNG just methane?

LNG is primarily methane (typically 85–95%), but it also contains small amounts of ethane, propane and other hydrocarbons. LNG can also contain trace amounts of nitrogen and carbon dioxide. The exact composition of LNG may vary depending on the source of the natural gas and the liquefaction process used.

 LNG fuel vs. fuel oil: is LNG better than diesel?

Compared to diesel fuel oil, LNG offers several advantages. LNG produces significantly lower emissions when burned, including:

  • 20–30% less CO2 
  • 15-25% less total GHG
  • 90% less NOx 
  • 99% less SOx 
  • Almost no particulate matter (PM) 

LNG engines are also quieter. 

However, LNG has a lower energy density than diesel, so using LNG as an alternative fuel for shipping will require more fuel and therefore larger fuel tanks to achieve the same range.

 What are the advantages and disadvantages of LNG fuel?

The key advantages of LNG as fuel include reduced emissions and cost competitiveness. There is also an established and continuously growing global network of LNG bunkering facilities.

The disadvantages of using LNG as fuel for ships include the need for specialised equipment and training and the potential for methane slip.

Methane slip is when unburned methane, a potent greenhouse gas, escapes into the atmosphere. Modern dual-fuel engines will minimise this issue. Depending on engine type and load, you can reduce methane slip by up to 65% by upgrading your ship’s existing engines. Over the last 30 years, Wärtsilä has reduced the methane slip from its engines by around 90%.

 Is LNG environmentally friendly?

LNG is cleaner burning than traditional marine fuels, but it is still a fossil fuel. BioLNG, which is LNG produced from organic waste or biomass, can be considered a more sustainable alternative to fossil-based LNG as it has a lower carbon footprint. However, the production and combustion of bioLNG still emit some greenhouse gases. LNG can be seen as a bridging fuel in the transition to alternative fuels like methanol and ammonia, which aren’t yet widely available at scale.

 Is LNG a future fuel?

LNG both is and isn’t a future fuel. It enables lower greenhouse gas emissions and reduces other harmful air pollutants compared to fuel oil, but it is still a fossil fuel. Sustainable future fuels are crucial for maritime decarbonisation, but the current cost, limited availability and insufficient infrastructure are challenging for operators. This gives LNG an important role to play in the shipping industry’s transition to a zero-carbon future.

As more ports develop LNG bunkering infrastructure and more ships are built with LNG fuel systems, the use of LNG as an alternative fuel for shipping is expected to increase. LNG is considered a stepping stone on the path to decarbonisation as the industry moves closer to using true future fuels such as methanol and ammonia.

ENGINE on Fuel Switch Snapshot: Bunkering gets pricier in Singapore

Once a week, bunker intelligence platform ENGINE will publish a snapshot of alternative and conventional bunker fuel prices in the world’s two biggest bunkering hubs. The following is the latest snapshot:

24 June 2024

Singapore's bunker fuel prices have increased across the board over the past week. Conventional fuel prices have climbed $17-20/mt higher, while bio-bunker blends have gained slightly less, at $12-17/mt. LNG has increased by $14/mt in the port.

The price gap between Rotterdam's LNG and VLSFO grades has narrowed in the past week. LNG is now only $2/mt cheaper than VLSFO in Rotterdam with estimated EU Allowance (EUA) costs for voyages between two EU ports added, down from $15/mt a week earlier. The price difference is wider without EUAs, at $8/mt, and has come down from $21/mt.

The B24-VLSFO premium over pure VLSFO has moved $2/mt lower in Rotterdam and $8/mt lower in Singapore.

VLSFO

Rotterdam’s VLSFO benchmark has increased by $7/mt in the past week. Steady availability of the grade in Rotterdam and the wider ARA region could explain its gains falling short of a $19/mt ($2.62/bbl) jump in front-month Brent futures.

Singapore's VLSFO benchmark has climbed $20/mt in the past week, mirroring Brent's rise.

A sharp tightening of VLSFO availability in the port has supported price gains. Most suppliers indicate lead times of 7-17 days for the grade, a significant increase from 2-11 days the week prior.

Biofuels

Rotterdam’s B24-VLSFO HBE price has been steadier in the past week, with only a $5/mt gain. Availability of bio-blended bunkers remains good in Rotterdam and the ARA hub, a source says. 

Singapore’s B24-VLSFO price has gained $12/mt in the past week. The bio-bunker price has gone up despite a $5/mt drop in the UCOME FOB China benchmark, according to PRIMA Markets.

“Lower offers last week of $960-980/t were still mostly met by limited demand, with other optimistic sellers still offering above $1,000/t in other areas of the country,” PRIMA said.

LNG

A $7/mt decline in Rotterdam’s LNG bunker price can be attributed to a drop in the front-month NYMEX Dutch TTF Natural Gas benchmark amid the abundant gas storage levels in European countries.

In contrast, Singapore’s LNG bunker price has jumped higher by $14/mt in the past week.

The price rise in Singapore is supported by higher prices in the Asian LNG market and the Japan/Korea Marker (JKM) price, as well as an extended outage at Chevron's Wheatstone LNG facility in Australia.
