Classification society DNV on Thursday (23 June) said it has awarded an Approval in Principle (AiP) to Korea Shipbuilding & Offshore Engineering (KSOE) and its subsidiary Hyundai Heavy Industries (HHI) for their newly developed waste heat-derived LNG fuel supply system Hi-eGAS (Hyundai High Efficient Gas Supply System) for 300K VLCC.

Currently, LNG fuel propulsion ships have used boilers to make hot steam, which has converted LNG into a gas at room temperature to supply a ship’s engine. However, this process has the disadvantage of increasing fuel costs and carbon emissions.

The concept of the waste heat of engine cooling water as a heat source for LNG-fuelled ships has been trialled previously, but commercialization was not successful due to concerns that engine performance could be negatively affected, said DNV. 

Hi-eGAS consists of a safety system in which the engine will continue running normally in the event of an incident to the LNG fuel system, such as forcing vaporizer leakage or failure of the JCW booster pump, temp and pressure control valves.

The system utilizes a new heat exchanger with low freezing risk, which KSOE and HHI developed in cooperation with domestic equipment companies.

Korea Shipbuilding & Offshore Engineering successfully completed a 24-hour demonstration test last year at the LNG Cryogenic Mechanical Testing Certification Center at the Korea Institute of Machinery and Materials under the same conditions as the maximum fuel supply for large ships.

“KSOE and HHI are leading the development of reducing carbon emissions and high-efficiency ship technology that increases the competitiveness of LNG fuel propulsion ships. I believe that AIP of this technology, proven by DNV, can provide more confidence in stakeholders' choices and support shipping industries to lower fuel price and CO2 emissions,” said Byeongyong Yoo, Vice president of KSOE.

As the International Maritime Organization's environmental regulations, especially on ships’ carbon emissions, are tightened, LNG is expected to become a primary fuel for ships. In total, 805 LNG-fuelled vessels are on order or in operation, with a further 229 LNG-ready vessels, according to DNV’s Alternative Fuels Insight (AFI) platform. In 2022 alone, more than 150 vessels were ordered with LNG as ship fuel.

“DNV aims to support the transition of the shipping and shipbuilding industries to a cleaner, green future. Our role is to ensure the new technology will offer better solutions to the maritime industry in a continually evolving fuel landscape,” said Vidar Dolonen, Regional Manager DNV Maritime Korea & Japan.

Malaysia: MMEA detains tanker for illegal anchoring in East Johor waters

The Malaysian Maritime Enforcement Agency (MMEA) on Tuesday (28 November) said a Panama-registered tanker has been detained for illegally anchoring in East Johor waters on 27 November.

MMEA Tanjung Sedili Zone acting director Maritime Cmdr Mohd Najib Sam said the tanker was detained by a patrol boat at 11am at 15.8 nautical miles northeast of Tanjung Penawar.

The captain of the vessel failed to produce any documents that permission had been obtained to anchor in Malaysian waters.

DNV paper outlines bunkering of alternative marine fuels for boxships

Classification society DNV recently released the third edition of its paper series Alternative fuels for containerships, focused on LNG, methanol and ammonia as alternative bunker fuel options for containerships.

In its updated paper series, DNV examined the different alternative marine fuel options and provided an overview of the most important technical and commercial considerations for the containership sector.

It explored the bunkering technology for LNG, bunkering infrastructure for methanol, and availability and infrastructure of ammonia. 

Building on the foundation laid in the second edition, which focused on the most important aspects of methanol as a fuel, this latest third edition delves deeper  – exploring the technical intricacies and commercial considerations associated with adopting methanol as an alternative fuel for containerships.

Furthermore, it provides an overview of crucial aspects related to ammonia and discusses its potential as an alternative fuel for containerships.

Amongst others, the new edition of the paper looks at the following aspects:

  • Technical design considerations for methanol
  • Commercial implications of adopting methanol as an alternative fuel
  • Ammonia's potential as an alternative fuel
  • Availability, infrastructure and ship fuel technology for ammonia
  • Major updates based on the latest IMO GHG strategy decisions at the MEPC 80 meeting

EDF, LR and Arup launch tool scoring ports’ potential to produce and bunker electrofuels

Lloyd’s Register (LR) Maritime Decarbonisation Hub and Environmental Defense Fund (EDF), in collaboration with Arup, on Tuesday (28 November) introduced the Sustainable First Movers Initiative Identification Tool, a system to help shipping stakeholders align investment decisions that support the maritime energy transition away from fossil fuels.

The tool, which is presented in a preliminary findings report – The Potential of Ports in Developing Sustainable First Movers Initiatives – scores a port’s potential to produce and bunker electrofuels while delivering local environmental and community benefits in alignment with the global temperature target of 1.5 degrees Celsius set by the Paris Agreement.

“Ports can play an important role in kickstarting shipping’s decarbonisation process even before global policies are established,” said Marie Cabbia Hubatova, Director, Global Shipping at Environmental Defense Fund.

“By considering the impact sustainable first mover initiatives can have on port-side communities, climate, environment and economies, resources can be better directed to locations where these initiatives will make the biggest difference.”

With close to two billion people living near coastal zones globally, the role of, and impacts on local port communities must be intentionally considered as the sector decarbonises globally. Ports can play a crucial role in ensuring shipping decarbonisation efforts are done in a way that has positive impacts on port communities.

The preliminary phase of the Sustainable First Movers Initiative Identification Tool analyses 108 ports in the Indo-Pacific region according to five criteria including land suitability, air quality, renewable energy surplus, economic resilience and ship traffic.

It is also applied to three different port scenarios, including ports exploring fuel production and bunkering, ports exploring fuel exports, and ports exploring fuel imports and bunkering. The combined criteria and scenario evaluation determines which ports have the greatest potential (high potential) for sustainable first mover initiatives to lead to significant emissions reductions and positive impacts in nearby communities, such as improved air quality and economic resilience.

“The transition to clean energy supply for shipping can be achieved only if stakeholders act together. Identifying potential port locations is the first step in this process,” said Dr Carlo Raucci, Consultant at Lloyd’s Register Maritime Decarbonisation Hub. “This approach sets the base for a regional sustainable transition that considers the impacts on port-side communities and the need to avoid regions in the Global South lagging behind.”

Regions in the Global South are fundamental in driving the decarbonisation of shipping. To make this transition effective, the rate at which different countries adopt and scale up electrofuels must be proportional to the difference in capital resources globally to avoid additional costs being passed on to local communities. Sustainable first mover initiatives can play an important role in making this happen by ensuring the sector’s decarbonisation is inclusive of all regions and by engaging all shipping stakeholders, including port-side communities.

“There’s a huge opportunity for early adopter shipping decarbonisation initiatives to unlock benefits for people and planet – shaping the way for a more equitable transition in the 2030s,” said Mark Button, Associate, Arup. “Our collective approach shows that taking a holistic view of shipping traffic, fuel production potential and port communities could help prioritise action at ports with the greatest near-term potential.”

The tool can be customised according to stakeholders’ needs and goals and is dependent on scenario desirability. The next phase of this work will include the selection and detailed assessment of 10 ports to help better understand local needs and maximise the value offered by sustainable first mover initiatives. 

LR and EDF carried out a joint study on ammonia as shipping fuel, and LR and Arup have collaborated on The Resilience Shift study focused on fuel demand for early adopters in green corridors, ports, and energy systems, amongst many other projects.
