Importantes actores de la industria marítima se han unido en un esfuerzo de colaboración para implementar la innovadora solución de reducción de metano SlipPureTM de Daphne Technology en el buque de GNL Maran Gas Chios del Grupo Angelicoussis.
Con Daphne Technology SA como proveedor de tecnología, el proyecto implica la integración de su innovador sistema SlipPure™ en un transportador de gas natural licuado (GNL), lo que representa una importante iniciativa piloto.
Los actores clave de la industria marítima, incluidos Lloyd’s Register (LR) como auditor independiente, Maran Gas Maritime Inc. como operador de buques, Wärtsilä como proveedor de motores, Shell International Trading and Shipping Company Limited (Shell) como fletador de El buque y el coordinador del proyecto, y DNV, que proporciona las aprobaciones de clase pertinentes para la modernización, se han embarcado en este esfuerzo conjunto para reducir las emisiones de metano.
La solución SlipPure™ de Daphne Technology, que el año pasado obtuvo la aprobación en principio de LR y DNV, es un sistema de postratamiento que reduce las emisiones de metano de los motores alimentados con GNL, el llamado deslizamiento de metano. El deslizamiento de metano provoca un aumento de las emisiones de gases de efecto invernadero (GEI) y del ozono a nivel del suelo.
El deslizamiento de metano se ha reducido significativamente en los motores modernos gracias al desarrollo continuo de las tecnologías de combustión, pero sigue siendo un desafío en los buques propulsados por GNL que utilizan tecnologías de motores más antiguas.
La tecnología SlipPure™ de Daphne permite una mayor reducción del metano en los gases de escape hasta niveles insignificantes[1] y es complementaria a las tecnologías y desarrollos de Wärtsilä.
This trial, which will see Daphne Technology’s system retrofitted to one of the Wärtsilä 34DF auxiliary engines on board the LNG carrier Maran Gas Chios, will facilitate the technical assessment and system feasibility analysis on SlipPure™ technology, supporting maritime stakeholders involved in the gas sector to de-risk their assets. For the SlipPure™ solution, HAZID and HAZOP workshops have been completed by LR as part of LR’s Risk-Based Certification process.
Daphne Technology’s PureMetrics™ solution will also be installed onboard the Maran Gas Chios throughout the trial period, and LR will handle the dissemination of the data as an independent third-party verifier. PureMetrics™ is an advanced system that directly measures and reports real-time GHG emissions, eliminating the reliance on fuel consumption estimates and ensuring compliance with European Union Monitoring, Reporting and Verification (EU MRV) and International Maritime Organisation Data Collection System (IMO DCS ) regulations. PureMetrics™ was awarded approval in principle from LR in June 2023 at Nor-Shipping.
Panos Mitrou, Global Gas Segment Director, Lloyd’s Register, said: “LR is pleased to work alongside industry leaders on this joint development project as the maritime industry raises critical challenges in addressing methane emissions from shipping. LR’s AiP has enabled this technology to proceed to a milestone pilot application, and the learnings from this trial will support gas industry partners in de-risking their gas assets.”
Andreas Spertos, Technical Director at Maran Gas Maritime Inc., said: “Maran Gas sees LNG as a readily available and mature fuel which offers substantial GHG reduction compared to the standard fuels used in shipping. At the same time, we are aware that the reduction of methane slip from dual-fuel marine engines to levels that are technically achievable is a key aim for the sustainability of LNG as fuel. Operating a very large fleet of LNG Carriers of different propulsion technologies, Maran Gas believes that addressing methane slip will help release all the potential of LNG as a low GHG emissions fuel.
Joining this project together with Shell, LR, Daphne and Wartsila and deciding to install the Daphne SlipPureTM methane abatement solution on one of our ships shows our commitment to work jointly with high-profile partners towards exploring solutions to handle the methane slip. We look forward to seeing the results of the SlipPureTM trial installed onboard our ship .”
Steve Brown, Technology Manager at Shell, emphasises: “Reducing methane emissions is a top priority for the maritime industry, and this trial of innovative technology on an operational ship marks an important milestone. LNG is the lowest-carbon marine fuel available at scale today, and this project, combined with efforts to reduce upstream methane emissions, will help to enhance LNG’s decarbonisation potential even further.”
Grant Gassner, Director, lntegrated Systems & Solutions, Power Supply – Wärtsilä, says: “Investing in methane slip reduction technologies forms a very important part of our wider strategy, ensuring we can continually improve the environmental and economic performance of our customers. Cross-collaboration with stakeholders across the maritime industry is key to this, with projects such as this playing a pivotal role in developing potential solutions towards eliminating methane slip across the maritime industry. Wärtsilä is grateful for the opportunity to contribute to this initiative, and we look forward to the outcome of the project.”
Martin Cartwright, Global Business Director, Gas Carriers and FSRUs DNV: “I am happy to see industry leaders collaborating on this trial of Daphne Technology’s SlipPure™ system. This initiative aligns with DNV’s commitment to facilitating the maritime industry’s transition towards decarbonisation. Methane slip can be a challenge in operating LNG-powered vessels, and solutions like SlipPure™, which has received approval in principle from DNV, are important in reducing these emissions. This trial represents a step forward in our collective efforts to mitigate greenhouse gas emissions and increase the sustainability of the maritime sector. We look forward to the insights this trial will provide.”
Daphne Technology, CEO & Founder Dr Mario Michan ended by saying: “We are thrilled to see this pilot project taking shape together with industry leaders to address methane emissions with our SlipPure™ solution. By retrofitting our technology onto an LNG carrier, we aim to showcase its effectiveness in reducing methane slip, contributing to a more sustainable and environmentally responsible maritime industry. This collaboration with Lloyd’s Register, Maran
Gas, Shell, DNV and Wartsila demonstrates the collective commitment to tackling greenhouse gas emissions and marks a significant step forward in our journey to decarbonise hard-to-abate industries.”
