Overview
RV Corella (LT767) was a fisheries research vessel that was operated by the Ministry of Agriculture, Fisheries and Food (United Kingdom) - Directorate of Fisheries, now known as the Centre for Environment, Fisheries and Aquaculture Science (Cefas) between 1967 and 1983. She was constructed by Brooke Marine in Lowestoft, and subsequently operated out of the port of Lowestoft. In 1983 the RV Corella was sold to Warbler Shipping and renamed MV Dawn Sky. In 1985 she was converted into an offshore supply vessel and one of her two distinctive A-frame winches was removed. Between 1986 and 1988 the Dawn Sky was re-chartered for government fisheries survey work, both by the Department of Agriculture and Fisheries (Scotland) and the Ministry of Agriculture, Fisheries and Food (United Kingdom). Warbler Shipping was bought by Putford Enterprises (of Great Yarmouth) in 1994, subsequently part of the American supply ship operators Seacor Holdings. The MV Dawn Sky was renamed MV Putford Sky and was used by BP on the Amethyst gas field off Yorkshire. She was sold to Fornæs Shipbreaking for scrapping in Denmark, leaving Great Yarmouth 6 April 2012 on her final voyage to Grenaa, 45 years after she had been constructed.
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
