Gas Carriers
ABOUT
Gas Carriers
Gas carriers are specialised vessels designed to transport liquefied gases such as ammonia and LPG under controlled pressure and temperature. They play a critical role in global energy and chemical supply chains and are today the primary means of transporting ammonia at scale. As demand for ammonia grows, both as an industrial product and as a zero-carbon energy carrier, gas carriers represent a natural and practical starting point for the transition to ammonia as marine fuel.
ABOUT
Navigator Amon Shipping
Amon Maritime views ammonia-fuelled gas carriers as a foundational part of the upstream ammonia value chain. They enable large-scale distribution and logistics, support market development and help establish fuel availability for ammonia-powered shipping. Through Navigator Amon Shipping AS, a joint venture established in 2025 with Navigator Gas, Amon Maritime is developing gas carriers that set a global benchmark for decarbonisation across commercial shipping
The joint venture has contracted two 51,350 cubic metre midsize gas carriers, purpose-built for the transportation of ammonia and LPG, with ammonia as the primary fuel. The shipbuilding contract has been signed with CIMC Sinopacific Offshore and Engineering in China, with deliveries scheduled for June and October 2028. The project was awarded a NOK 180 million investment grant from Enova in 2024.
Each vessel is secured by a long-term charter agreement with Yara, anchoring the project in established industrial ammonia trade while enabling early deployment of ammonia as marine fuel at scale. Beyond their role as transport assets, the gas carriers serve as a strategic enabler for Amon Maritime’s broader portfolio of ammonia-fuelled vessels. By distributing ammonia at scale, they support fuel availability for downstream ship projects, including bulk carriers and other ammonia-powered tonnage developed by Amon Maritime. In this way, the gas carrier segment forms a critical link between ammonia production, distribution, and end use, strengthening the overall value chain.
The vessels feature an ammonia-capable dual-fuel main engine and one ammonia-capable dual-fuel auxiliary engine. This configuration enables exceptionally low tank-to-wake greenhouse gas emissions when operating on low-carbon or carbon-free ammonia. Dedicated ammonia fuel tanks are located on deck, enhancing safety, inspection accessibility, and operational robustness. The vessels will be built to Ice Class 1A, allowing reliable operation in ice-affected waters.
When transporting LPG, the vessels can operate on ammonia fuel for extended periods without bunkering. In ammonia trade, fuel can be drawn directly from cargo, effectively removing dependence on early-stage bunkering infrastructure and addressing a key barrier to adoption.
