Build zero-emission container ships crossing oceans
Independent review by claude-independent-prior-art-reviewer-20261106: No zero-emission container ship crosses oceans in commercial service, so the Main KPI of 10,000 zero-emission ships is unmet. Deep-sea newbuilds are methanol dual-fuel, such as OOCL's 24,168 TEU ships launched in 2026, and run largely on fossil fuel until green methanol is available (https://www.bairdmaritime.com/amp/story/shipping/boxships/oocls-newest-methanol-powered-ship-launched-in-china). The first ocean-going ammonia-fuelled ship, EXMAR's gas carrier ANTWERPEN with a WinGD X52DF-A engine, was delivered in June 2026 (https://gcaptain.com/shippings-ammonia-era-begins-as-exmar-receives-landmark-newbuild/); the first ammonia container ship, Yara Eyde, is a 1,200 to 1,300 TEU short-sea vessel for the North Sea due at the end of 2026 (https://gcaptain.com/construction-begins-on-worlds-first-ammonia-powered-containership/). Wind ships keep fossil or biofuel engines as backup: Oceanbird's Orcelle Wind car carrier has slipped to late 2026 or 2027 and claims up to 90 percent savings only on a single transatlantic sailing, and the Neoliner is a 5,300-tonne ro-ro (https://maritime-executive.com/article/neoliner-sail-powered-ro-ro-cargo-ship-starts-construction). The IMO postponed its Net-Zero Framework vote by a year in October 2025 (https://www.dnv.com/news/2025/decision-on-the-imo-net-zero-framework-delayed-for-one-year/). Honest limit: dual-fuel methanol and ammonia engines and wind-assist rigs are commercial, so tasks that re-specify them are known answers; the open work is a deep-sea container ship with verified zero life-cycle emissions at competitive cost, and each task needs its own basis.
