Dual Fuel Vessel Management: Advancing Maritime Decarbonisation
For some time now, the maritime sector has been undergoing a pivotal shift toward cleaner propulsion systems, and dual fuel technology sits at the heart of this transformation. Designed to operate on both traditional marine fuels and alternatives such as Liquefied Natural Gas (LNG), dual fuel vessels represent a crucial step in meeting the industry’s regulatory and sustainability imperatives.
To dual fuel vessel management Synergy Marine Group brings deep technical expertise, operational discipline and a proven record of execution, and our integrated services support shipowners through the full lifecycle of alternative fuel adoption—from project inception to operational readiness and beyond.
Integrated Dual Fuel Management Services
Our approach has four core pillars, ensuring safe, compliant and future-ready dual fuel operations:
- Technical Management and Project Delivery
Synergy offers full-scope technical management for LNG-fuelled and dual fuel vessels, encompassing:
- Fuel System Oversight: Management of LNG supply systems, vaporizers, BOG compressors, glycol circulation units and safety interlocks;
- Life cycle Engineering Support: From newbuild specification reviews and plan approvals to gas trials and operational optimisation;
- Asset-Specific Experience: Notable references include the fully refrigerated LPG carrier MIRAI, capable of transporting LNG, ammonia and VCM; SG HORIZON, an LNG dual–fuel Newcastlemax bulk carrier delivered from Namura Shipyard’s Imari facility and equipped with a dual–fuel main engine, Type-C LNG fuel tank and advanced energy-saving technologies; the dual–fuel Aframax tanker PACIFIC EMERALD, Singapore’s first oil tanker to be bunkered via the LNG vessel FUELNG BELLINA; and the ARCTIC TERN, a Synergy-managed dual–fuel container vessel operating on bio-methane-ready LNG that recently received Green Ship Status from the Maritime and Port Authority of Singapore.
Also, our experience in managing multiple sister vessels of the PACIFIC EMERALD includes compatibility studies and LNG bunkering operations across the US Gulf, Singapore, Rotterdam, Gothenburg and other key locations.
- LNG Bunkering and Global Fuel Readiness
By early 2025 Synergy had supported over 100 LNG bunkering operations globally, providing services which include:
- Bunkering Compatibility Studies: Assessment of LNG barge and terminal compatibility at key supply points;
- Port Readiness Planning: Guidance on port infrastructure and regulatory requirements;
- Operational Supervision: On-site management of bunkering activities to ensure adherence to safety protocols and minimisation of downtime.
- Crew Training and Operational Familiarisation
Operating dual fuel vessels demands advanced crew competencies. At our dedicated Marine Advanced Simulation and Training Centres, Synergy offers:
- Scenario-based Training Modules: Covering LNG bunkering, fuel gas supply system operation and emergency procedures;
- Engine Room Simulation: Live model-based simulation of dual fuel engines and auxiliaries;
- Certifications and Competency Mapping: Crew readiness is verified through structured assessments aligned with international standards.
- Decarbonisation Strategy and Future Fuels Advisory
Our role extends beyond technical execution—we also support shipowners in long-term energy transition planning:
- Fuel Transition Roadmaps: Guidance on switching pathways, such as from LNG to bio-LNG or e-methane;
- Vessel Design Input: Optimisation for future retrofits and multi-fuel adaptability;
- Partnerships and Policy Alignment: Active participation in the Society for Gas as a Marine Fuel (SGMF) and other decarbonisation forums.
Synergy is currently engaged in collaborative projects involving biofuels, methanol and green ammonia, including frontier trials on vessels like the MONAX and the IRON PHOENIX.
Operational Track Record: From Trial to Transition
Our technical teams have delivered real-world projects that demonstrate fuel flexibility and emission reduction across diverse vessel types.
- MIRAI: End-to-end project management for construction and technical handover, capable of carrying LNG, ammonia and VCM.
- SG HORIZON: Delivered from Namura Shipyard’s Imari facility, this LNG dual–fuel Newcastlemax bulk carrier represents a forward leap in clean-fuel propulsion for the dry bulk segment. Equipped with a dual–fuel main engine, Type-C LNG fuel tank and advanced energy-saving technologies, SG HORIZON enables substantial reductions in CO₂, SOₓ and NOₓ emissions—fully aligned with the IMO’s decarbonisation targets and NYK Line’s NYK GREEN EARTH sustainability programme.
The vessel also deepens Synergy Marine Group’s long-standing collaboration with NYK Line, highlighting our shared commitment to safe, reliable and environmentally responsible operations. Through our expanding pool of officers and crew trained in dual–fuel and Japanese-flag operations, we continue to advance operational excellence in next-generation shipping. - PACIFIC EMERALD: Oversight of a complete LNG-capable propulsion system, including ME-GI engines, auxiliary boilers and dual-mode generators, with LNG bunkering operations across the US Gulf, Singapore, Rotterdam and Gothenburg.
- MONAX and IRON PHOENIX: Biofuel voyages demonstrating measurable emission reductions and supporting ongoing trials involving methanol and green ammonia.
These projects collectively demonstrate Synergy’s ability to manage dual–fuel and alternative-fuel vessels across the full lifecycle—from design review and commissioning to safe, efficient operation—reinforcing our position as a trusted partner in the energy transition.
