The Samsung Heavy Industries (SHI) yard in South Korea will be constructing four “next generation” shuttle tankers for marine energy transportation, storage and production company Teekay.

The dual-fuel engines of these shuttle tankers are not only able to operate on liquefied natural gas (LNG) as the primary fuel, but also consume a mixture of LNG and recovered volatile organic compounds (VOC) as an energy source.

VOC is the gas evaporating from the oil cargo tanks during loading; by utilising the recovered VOC as fuel rather than venting it to the atmosphere the harmful emissions will be eliminated and the ships’ bunker needs will be significantly reduced, says Wartsila.

The concept means nitrogen oxide (NOx) emissions from the engines’ exhaust will be reduced by more than 80%, sulphur oxide (SOx) emissions will be almost entirely eliminated, while particulate emissions will be reduced by more than 95%.

It is also expected to produce a significant reduction in fuel consumption compared to conventional solutions. 

“Together with Teekay, we have developed a concept that takes the shuttle tanker sector into a new era, and which is further evidence of Wärtsilä’s ability to transform shipping by developing and utilising the very latest technologies,” says Roger Holm, President, Wärtsilä Marine Solutions.

“These ships will have tremendous operational flexibility with unmatched manoeuvring capability, and will achieve what all operators are striving for today, namely optimal economic and environmental performance.”

“This new shuttle tanker design will set new standards for both fuel consumption and CO2 emissions,” adds Terje Rusdal, Project Manager at Teekay.

2050 Marine Energy Owner Adrian Tolson to discuss global MFM adoption in webinar

International shipping association BIMCO will be organising a 15+15 webinar featuring 2050 Marine Energy Owner Adrian Tolson on Wednesday (12 June).

Early in 2024, Tolson published a White Paper arguing for the global adoption of calibrated mass flow meters (MFMs) in the bunkering industry. 

He argued that this progress will bring much-needed transparency to bunkering by generating accurate, real-time data for all stakeholders along the marine fuel supply chain. 

Describing the problems for the industry caused by inaccurate quantity measurement he sets out a number of remedial actions.

The paper recognises the success of Singapore’s MFM based bunker licensing system and proposes this as a template for regulators in other regions across the world. 

It calls on all supply chain participants to actively support MFM-based deliveries, promote transparency and encourage digitalisation in the long-term interests of the bunker industry and to help further the decarbonisation goals of the shipping industry. 

“This 15+15 will explore these ideas and assess if there is a chance for real progress,” BIMCO said on its website.

The 30-minute webinar, titled Getting what you pay for – a novel concept in bunkering? begins at 12:00 UTC.

The 15+15 weekly webinars are a 30-minute webinar which includes a 15-minute presentation followed by a 15-minute Q&A.

RESIZED ExxonMobil

ExxonMobil on Friday (7 June) said its advanced 40BN cylinder oil, Mobilgard™ 540 AC, has been validated by WinGD for use in its dual fuel marine engines with conventional fuels, including methanol, and now LNG. 

The high performance cylinder oil, which also has an approval from MAN ES for use in its two-stroke engines, was developed for use in slow-speed, two-stroke marine engines operating on fuels with up to 0.50% sulphur content, LNG, ethane, methanol and LPG.

Mobilgard 540 AC has demonstrated an excellent ability to keep the engine clean while running in gas mode at optimised low feed rates. The oil is also suitable for methanol operation and with other liquid fuels up to 1.5% sulphur levels. 

This comes in addition to the existing MAN ES Category II approval, positioning the oil as a supreme oil in the two stroke marine engine space.

“Vessel operators need reliable, high performance solutions, now more than ever,” explained Yannis Chatzakis, Global Technology Program Manager at ExxonMobil. 

“This double validation underscores ExxonMobil’s commitment to delivering both. As with all our cylinder oils, Mobilgard 540 AC has been developed using our balanced formulation approach. This helps ensure outstanding protection at optimum feed rates, supporting the peace of mind our customers need.”

Used in conjunction with a next generation scrape-down oil analysis service, such as Mobil℠ Cylinder Condition Monitoring, the cylinder oil can help:

  • Deliver exceptional cleanliness with low-sulphur fuel due to high level of detergenc
  • Combat deposits and scuffing-related engine wear associated with low-sulphur fuels
  • Ensure performance even in severe operating conditions as a result of excellent thermal and oxidative stability

The firm added Mobilgard 540 AC has demonstrated the ability to deliver these benefits while optimising cylinder oil feed-rates and effectively managing acid neutralisation in a range of engines and fuel applications. 

The cylinder oil has already been granted Category II status by MAN ES for use in its two stroke marine diesel engines; the addition of the dual fuel validation from WinGD positions the oil as one of the highest performing in the market.

“ExxonMobil continues to work with stakeholders, including engine OEMs, from across the marine industry as we believe that this offers the best results for our customers and the wider maritime sector,” said Chatzakis.

“The next few years are likely to throw up new challenges as we collectively pursue a lower emissions future. Our commitment to innovation will help achieve that goal.”

Note: Mobilgard 540 AC is available in all major ports. Full details can be found in its Ports & Services Guide - www.exxonmobilportsandservices.com

DNV explores present state of onboard carbon capture in new white paper

Onboard carbon capture (OCC) is attracting interest within the shipping industry, providing shipowners with the opportunity to continue operating on conventional fuels while reducing emissions, said classification society DNV on Wednesday (5 June).

However, according to DNV’s latest whitepaper The potential of onboard carbon capture in shipping, its success depends on collaboration between regulators, policy makers, industry stakeholders, class, and suppliers.  

With decarbonization targets rapidly approaching, demand for cost-efficient solutions for emission reduction is increasing. DNV’s latest whitepaper explored OCC as a decarbonization solution for shipping by looking at its technical, economic, operational, and regulatory challenges, as well as its integration into the carbon capture, utilization, and storage (CCUS) value chain.

CCUS is the process of capturing CO2 and recycling it for future use or permanently storing it in deep underground geological formations. The maritime industry is exploring its application onboard ships, which will require an onboard system to capture, process and store the CO2, and a network of offloading which is integrated into wider CCUS infrastructure.

Chara Georgopoulou, Head of Maritime R&D and Advisory Greece, said: “OCC is expected to be part of a range of future options which will help shipping achieve its decarbonization goals. However, further collaboration and testing is required to verify its performance.”

“The commercial attractiveness of OCC will depend on the terms under which regulations can credit the removal of carbon emissions, and how smoothly it can be integrated into the growing CCUS value chain.” 

For OCC to be relevant for wider application it must be economically viable and competitive with other decarbonization alternatives. If successfully deployed, OCC can become a key way for shipowners to comply with decarbonization regulations, while also helping to reduce the demand for alternative fuels.

The EU ETS is the only regulatory framework currently providing commercial incentives for OCC. To encourage shipowners to adopt the technology, future environmental and greenhouse gas (GHG) emissions regulations must also provide credit for captured CO2.

“If we are to achieve IMO decarbonization targets, we must leave no stone unturned in continuing to investigate OCC and other potential technologies that can accelerate shipping’s decarbonization journey,” Georgopoulou said.
