VTT to research on increasing propulsion efficiency of vessels to lower fuel consumption

By designing ships’ propellers and hulls differently, it can lead to lowered fuel consumption regardless of fuel type, says the Finland-based research group.

Finland-based research group VTT is teaming up with industry partners on the UltraPropulsor Co-Innovation project to study increasing propulsion efficiency by developing new propulsion concepts and improving hull design to significantly reduce fuel consumption, shipping emissions and underwater noise.

VTT said currently the propulsive efficiency of ships, meaning how much of the power delivered to the propeller can be used for propelling the ship, is about 70 %. 

This can be significantly improved by developing new propulsor and hull form innovations. This kind of improvement is also not dependent on the fuel type used and leads always to lowered fuel consumption, it added. 

Besides the GHG emissions, underwater radiated noise has been recognised as a major environmental issue in the shipping industry. 

“VTT is tackling this challenge with industry partners and is developing new methods to model the underwater noise and propeller cavitation phenomena. By better understanding the sources for the underwater noise, it can be mitigated more effectively,” said the research group. 

“The main goal of the research project is to significantly increase the propulsive efficiency of ships by developing new propulsion concepts. Increase in propulsive efficiency leads directly to lower fuel consumption and lower emissions. Concurrently we are looking for solutions to lower the underwater radiated noise of ships”, said research scientist Ilkka Perälä who is leading the project at VTT.

VTT received a USD 1.21 million funding from Business Finland for UltraPropulsor Co-Innovation project. The project develops future solutions for zero-emission shipping. Total budget of the co-innovation project is USD 4.5 million including the industry partner budgets. 

VTT contributes to the project with strong hydrodynamics and materials science expertise to minimise ship energy consumption and enabling the development of novel low emission solutions and concepts. 

Industrial partners in the project are ABB, Foreship, ATA Gears and Composite Solutions and Innovations. VTT acts as a research partner supporting the research needs of the industry partners. The consortium brings together strong expertise from different domains of the maritime sector. 

Main topics of the research project include hydrodynamic research to demonstrate the feasibility of novel solutions by numerical modelling and experiments, and material research to develop methods for strength assessment of propeller blades.

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.

Classification society ClassNK on Thursday (18 July) said it signed a Memorandum of Understanding (MoU) with ITOCHU Corporation, Nihon Shipyard Co., Ltd., and Maritime and Port Authority of Singapore (MPA) regarding a joint study for the design and safety specifications of ammonia-fuelled ships which are under development by ITOCHU and partners.

“The discussion for a specification of ammonia-fuelled ships with a governmental body related to their operation is essential for a social implementation of ammonia-fuelled ships,” ClassNK said. 

“As one of parties of the MoU, MPA, a government agency overseeing the world’s busiest bunkering hub, will review and provide their views to the designs of the ammonia-fuelled ships to ensure their safe operations.”

The MoU is based on the premise that 200,000 deadweight ton class bulk carriers will be built by Nihon Shipyard with an ammonia dual-fuelled engine.

“The necessary clarifications of the specification for the ammonia-fueled ship to carry out ammonia bunkering in Singapore will be conducted among parties of this MoU, for the commercialisation of ammonia-fuelled ships,” ClassNK added.

“K” Line to use biofuel on three Gram Car Carriers-chartered vessels in Singapore

Norwegian transportation firm Gram Car Carriers (GCC) on Thursday (18 July) said Kawasaki Kisen Kaisha (“K” LINE) will use biofuel on three vessels chartered from GCC from July onwards. 

“The biofuel will be supplied to the sister vessels Viking Ocean, Viking Diamond and Viking Coral while bunkering in Singapore, an Asian hub for marine biofuels,” GCC said on its social media. 

“The use of biofuel is a key environmental initiative to reduce emissions across the entire value chain (well-to-exhaust) and an effective way of transitioning to low-carbon marine fuels amid globally tightening environmental regulations.”

“We support the green mobility shift. This means that GCC commit to supporting the transition of both vehicles and their logistic chain towards a zero-emission future in close cooperation with leading customers such as K-Line,” said Georg A. Whist, CEO of GCC.
