Ocean Network Express (ONE) has celebrated the maiden voyage of its new S-series vessel, ONE Solidarity, a methanol- and ammonia-ready container ship that recently made its inaugural port call in Shekou. Deployed on the Mediterranean Pacific South 2 (MS2) service, the next-generation vessel expands global transit capacity while advancing the carrier’s long-term commitment to maritime decarbonization.
Singapore | July 2, 2026 – Ocean Network Express (ONE) has officially marked the maiden voyage of its latest next-generation container vessel, the ONE Solidarity, following its inaugural arrival at the Port of Shekou. The deployment represents a strategic double-down by the world’s sixth-largest liner on both the booming Mediterranean-Pacific trade lanes and its long-term decarbonization roadmap.
The arrival in South China, captured in cooperation with the China Merchants Port (South China) Management Center, highlights the carrier’s ongoing fleet modernization strategy under Chief Executive Officer Till Ole Barrelet.
Dual-Fuel Readiness Meets Transpacific Capacity
The ONE Solidarity enters service as part of ONE’s “S-Series,” a class of ultra-large container vessels meticulously engineered for future-fuel flexibility. Amid tightening global maritime emissions regulations, the vessel boasts methanol and ammonia-ready capabilities, allowing the carrier to seamlessly transition to zero- or net-zero carbon fuels as the global bunkering supply chain matures.
The vessel follows in the wake of its sister ship, the ONE Singapore, and is slated for immediate deployment on the Mediterranean Pacific South 2 (MS2) service.
According to regional trade analysts, adding a vessel of this scale to the MS2 loop does more than just inject raw TEU capacity into the market. It optimizes slot efficiency and transit reliability across highly volatile global trade corridors, connecting key Asian manufacturing hubs directly to Mediterranean and European gateways.
“The deployment of ONE Solidarity will boost our service capacity, ensuring faster, more reliable, and highly efficient shipping offerings across key global trade lanes,” ONE stated in a briefing, positioning the vessel as a primary vehicle for businesses looking to scope down their Scope 3 supply chain emissions.
Scaled for Global Logistics
The vessel’s integration into the network underscores the massive operational scale ONE has achieved since its establishment in July 2017 as a joint venture of Japan’s major liners.
| Metric | Operational Scale |
| Global Fleet Size | Over 280 Vessels |
| Total Carrying Capacity | Approximately 2.2 Million TEU |
| Network Reach | 165+ Shipping Services / 120 Countries |
| Global Workforce | 9,000+ Employees across 50+ Countries |
Operating from its global headquarters at Marina One East Tower in Singapore, ONE’s current business domain spans worldwide container operations and international terminal investments, excluding domestic operations in Japan.
Technical Profile
As a sister vessel to the ONE Sparkle, ONE Sapphire, ONE Sincerity, ONE Singapore, and ONE Satisfaction, the ONE solidarity follows a blueprint of extreme energy efficiency. For maritime professionals and technical managers, the vessel’s specs highlight a significant reduction in fuel demand per TEU:
- Capacity: 13,800 TEU with specialized high-capacity reefer plugs.
- Propulsion: Powered by a MAN B&W 7G95ME-C10.6 main engine, renowned for its low fuel-oil consumption and adaptability to dual-fuel retrofits.
- Environmental Tech: The vessel is equipped with a hybrid Exhaust Gas Cleaning System (EGCS) (scrubber) and Exhaust Gas Recirculation (EGR) for NOx Tier III compliance.
Navigating the Energy Transition
The maiden voyage of the ONE Solidarity comes at a critical juncture for the maritime industry, as carriers race to meet the International Maritime Organization’s (IMO) stringent greenhouse gas reduction targets.
By investing heavily in alternative-fuel-ready hardware like the S-Series, ONE is mitigating the risk of stranded assets. Should green methanol or ammonia production achieve commercial scale later this decade, the ONE Solidarity can be retrofitted with minimal friction compared to legacy heavy fuel oil (HFO) assets.
Guided by their corporate ethos, “As ONE, We Can,” the carrier is banking on these next-generation vessels to not only capture market share from sustainability-conscious BCOs (Beneficial Cargo Owners) but to fundamentally redefine their operational carbon footprint on the high seas.
About Ocean Network Express (ONE)
Established in July 2017 through the high-profile consolidation of Japan’s legacy liners, “K” Line, MOL, and NYK, Ocean Network Express (ONE) has rapidly evolved into the world’s sixth-largest container shipping carrier. Headquartered in Singapore and led by CEO Till Ole Barrelet, the company operates an expansive international logistics network featuring a fleet of over 280 vessels, a total carrying capacity of approximately 2.2 million TEUs, and more than 165 shipping services traversing 120 countries.
As part of its “ONE2030” strategic vision, the carrier is leveraging its massive scale to champion maritime decarbonization amid tightening global emissions mandates. By aggressively integrating dual-fuel asset designs, such as its newly deployed, methanol- and ammonia-ready S-series container ships, and testing sustainable marine biofuels, ONE is actively modernizing its fleet to provide eco-efficient, future-proofed supply chain solutions for the global energy and logistics sectors.
