In a collaborative industry effort, key maritime players are joining forces to test Daphne Technology’s cutting-edge Slip- Pure™ methane abatement system on Angelicoussis Group’s LNG carrier, Maran Gas Chios. Daphne Technology SA serves as the technology supplier for this notable pilot project, which integrates their SlipPure™ technology into a liquefied natural gas (LNG) vessel.
Among the stakeholders are Lloyd’s Register (LR), responsible for independent auditing; Maran Gas Maritime Inc., the ship operator; Wärtsilä, the engine provider; Shell International Trading and Shipping Company Limited (Shell), serving as the vessel charterer and project coordinator; and DNV, handling class approvals for retrofitting.
Daphne’s SlipPure™ system, which earned prior approval from LR and DNV, is an after-treatment solution designed to minimize methane slip, a contributor to increased greenhouse gas (GHG) emissions and ground-level ozone. While advancements in combustion technologies have already reduced methane slip in modern engines, challenges persist in older LNG-fueled vessels. The Slip- Pure™ technology aims to further reduce methane emissions to negligible levels and complements existing Wärtsilä technologies.
The trial will retrofit Daphne’s system to a Wärtsilä 34DF auxiliary engine on Maran Gas Chios. It aims to provide a thorough technical assessment of Slip- Pure™ technology, assisting gas sector stakeholders in risk mitigation. To facilitate risk assessment, LR has conducted HAZID and HAZOP workshops as part of their Risk-Based Certification process.
Additionally, Daphne’s PureMetrics™ will be installed on Maran Gas Chios during the trial. LR will oversee data dissemination as an independent third-party verifier. PureMetrics™ offers real-time GHG emissions monitoring and complies with European Union Monitoring, Reporting and Verification (EU MRV) and International Maritime Organisation Data Collection System (IMO DCS) regulations. The system received approval from LR in June 2023.
Panos Mitrou, Global Gas Segment Director at Lloyd’s Register, said, “We’re excited to work with industry leaders on this development project. Our AiP has paved the way for this pilot, which will offer valuable insights for gas industry stakeholders.”
Andreas Spertos, Technical Director at Maran Gas Maritime Inc., stated, “We view LNG as a mature fuel offering substantial GHG reduction. Addressing methane slip is essential for LNG’s role as a low GHG emissions fuel. Joining this project shows our commitment to seeking solutions for methane slip. We look forward to the trial results.”
