Vessels berthing at Singapore DNV

Classification society DNV has been selected to lead an ammonia bunkering safety study by the Global Centre for Maritime Decarbonisation (GCMD) in Singapore, it said on Wednesday (26 January).

The pioneering study aims to define a robust set of safety guidelines and operational envelopes that will establish the basis of a regulatory sandbox for ammonia bunkering trials at two local sites.

To that end, DNV will team up with Singapore’s leading infrastructure developer Surbana Jurong and the Singapore Maritime Academy (SMA).

DNV’s work scope will comprise ammonia demand forecasting, bunkering site recommendations, the development of conceptual designs of bunkering modes like truck to ship or ship to ship, HAZID/HAZOP/QRA studies, as well as drafting of technical and operational guidelines.

While ammonia is one the most promising fuels to decarbonize shipping, DNV research shows that a number of safety gaps hold the potential to disrupt the speed and success of the transition.

“The safe handling of ammonia is one such gap which urgently needs to be closed, given the threat it poses to seafarers and ships unless properly managed. We are therefore thrilled to partner with Surbana Jurong and the Singapore Maritime Academy on this pioneering initiative, which we hope will lay the foundations for robust ammonia bunkering safety guidelines with industry wide applicability”, said Knut Ørbeck-Nilssen, CEO of DNV Maritime.

In response to the growing industry interest for ammonia fuelled and ammonia ready ship designs, DNV has undertaken many trailblazing projects in the development of ammonia as a viable future marine fuel.

DNV’s “Fuel ready” notation was launched as an industry first in April 2021 by Höegh Autoliners in their new series of car carriers. The notation verifies that a vessel complies with the safety and operational requirements for future ammonia fuelled operations, and that the main engine can be converted or operate on the fuel.

For shipowners looking to move towards a full zero-carbon fuel option with their next newbuilding, DNV’s new “Gas fuelled ammonia” rules provide a practical path. Further adding to this work, DNV has awarded several Approvals in Principle for ammonia fuelled ship designs, while also cooperating with engine maker MAN Energy Solutions on the safe development of a 2-stroke ammonia engine intended to be market-ready in 2024.

“Next to our broad practical experience, our research detailed in the ‘Ammonia as a marine fuel’ white paper shows that we are well equipped to undertake this groundbreaking ammonia bunkering study”, comments Cristina Saenz de Santa Maria, DNV Maritime’s Regional Manager South East Asia, Pacific and India.

“We highly welcome that Singapore as the world’s leading bunkering port is exploring ammonia as a viable ship fuel and are very happy to be selected to contribute to the pilot. Safety is the prerequisite for the successful and timely introduction of new fuels such as ammonia, hence joint research and development, testing and setting standards is crucial at this point”, she adds.

According to its recent Maritime Forecast to 2050, DNV expects there will be demonstration projects for onboard use of ammonia by 2025, paving the way for zero-carbon ships ready for commercial use by 2030. While the future fuel mix will be broad, DNV predicts that both ammonia and bio-based methanol are the most promising carbon-neutral fuels in the long run.

GCMD concludes its final biofuel blend supply chain trial with Hapag-Lloyd

The Global Centre for Maritime Decarbonisation (GCMD) on Thursday (18 July) said it has successfully completed its final supply chain trial for biofuel blended with very low sulphur fuel oil (VLSFO). 

This marks the end of a series of trials initiated in July 2022 as part of a larger pilot to develop a framework to provide quality, quantity and GHG abatement assurances for drop-in fuels.

In this final trial, bp provided the B30 biofuel blend to the TIHAMA, a 19,870 twenty-foot equivalent unit (TEU) container vessel operated by Hapag-Lloyd.

The biofuel component used is certified to the International Sustainability & Carbon Certification (ISCC) standard – a multistakeholder certification scheme for biobased materials. The biofuel component comprised neat Fatty Acid Methyl Ester (FAME) produced from food waste.

Authentix, a tracer solutions provider, supplied and dosed the FAME with an organic-based tracer at the storage terminal outside the Netherlands. The dosed FAME was then transported to the Port of Rotterdam for blending with VLSFO to achieve a B30 blend, before the blend was bunkered onboard the TIHAMA.

Similar to previous trials, GCMD engaged fuel testing company Veritas Petroleum Services (VPS) to witness the operations at all stages – from biofuel cargo transfer to bunkering. VPS also collected and conducted extensive laboratory tests on samples of the biofuel and biofuel blend collected at pre-determined points along the supply chain to assess quality per Standards EN 14214 and ISO 8217.

With well-to-wake emissions of 13.74 gCO2e/MJ, the neat FAME presented a 85.4% emissions reduction compared to the emissions of the fossil marine fuel. The reduced emissions complies with the MEPC 80, which requires a minimum emissions reduction of 65% in order for biofuels to be classified as sustainable.

GCMD and Hapag-Lloyd determined that consumption of the 4,500 MT B30 blend of FAME and VLSFO resulted in 27.9% emissions reduction compared to sailing on VLSFO.

A newly developed tracer deployed with this supply chain

GCMD collaborated with Authentix to develop and deploy a new organic-based tracer to authenticate the origin and verify the amount of FAME present in the blend. The proprietary tracer blended homogeneously with FAME and was detected at expected concentrations at all sampling points along the supply chain.

This trial marks the first deployment of this tracer in a marine fuel supply chain. Previously, similar tracers were used to authenticate and quantify biofuels in road transport and LPG supply chains.

Development of a comprehensive biofuels assurance framework underway

With the completion of this trial, GCMD has deployed a diverse range of tracer technologies, including synthetic DNA and element-based tracers, in addition to the organic-based tracer used in this trial. The trials have also included the development of a chemical fingerprinting methodology and the evaluation of lock-and-seal and automatic identification systems (AIS) as additional solutions to ensure the integrity of the biofuels supply chain.

Learnings on tracer limitations and benefits will be incorporated into a framework that recommends appropriate use to ensure consistent and robust performance. This effort will complement existing ISCC by providing additional supply chain assurance through physical traceability.

The insights from these trials will be shared in a series of reports covering issues, such as traceability, biofuel degradation, supply chain optimisation and abatement costs. These findings will culminate in a comprehensive assurance framework to provide guidance on biofuels use, slated for release in the fourth quarter of 2024.
