Overview
Prairial was a supertanker, built in 1979 by Chantiers de l'Atlantique at Saint-Nazaire for Compagnie Nationale de Navigation. Prairial, which was the fourth and final vessel of Batillus-class supertankers (the other three were Batillus, Bellamya and Pierre Guillaumat). She was the only ship of that class to have a career longer than ten years, sailing until 2003, although under different names: Sea Brilliance (1985), Hellas Fos (1986) and Sea Giant (1997). She is also distinguished as the third biggest ship ever constructed, surpassed in size only by Seawise Giant (later Jahre Viking, Happy Giant, Knock Nevis, and finally Mont) built in 1976 and subsequently lengthened, and her sister ship Pierre Guillaumat. The vessel was completed and commissioned in 1979. As other ships of Batillus class, she was laid up, arriving at Vestnes, Norway on April 5, 1983, but was sold and recommissioned in 1985. She was in service under different names and owners until 2003, when she arrived at Gadani ship-breaking yard in order to be scrapped.
Composite Risk
Multiple adverse factors, or a hard ship-specific signal, lift this hull above the fleet norm.
A coverage-weighted blend of the single component we could read for this hull; the weights renormalise over only the components present, so a thin read is never inflated and a hull is never credited a “safe 0” for a signal it has no row for. This headline is flagged low-confidence (a thin or structural-only read) and should not be treated as a verdict. Higher means riskier. Derived in-house from government-open port-State-control, flag, sanctions and our own vessel data; weight it by the coverage above.
Commercial
