Overview
RV Clione (LT421) 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 1961 and 1988. She was constructed by Cochrane Shipbuilders Ltd., of Selby (Yorkshire) in 1961 and operated out of the port of Lowestoft. In early 1988 the RV Clione was sold to Putford Enterprises of Great Yarmouth, and converted into an offshore oil rig stand-by ship. However, she was re-hired by the Ministry of Agriculture, Fisheries and Food (United Kingdom) in December when the Ministry's new survey vessel RV Corystes was taken out of service at short notice, requiring a change of propeller. The RV Clione was renamed as the MV Putford Petrel on 3 May 1991. In 2000 the MV Putford Petrel was sold again and converted to a motor yacht. She was renamed as the Lynn G and is currently listed as being owned by the Dutch Film Unit – Lettele, Netherlands, although her whereabouts are unknown.
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
Price it in the Route Planner between any two commercial ports: ballast and laden legs, two fuels at live bunker prices, port and canal costs, the weather on the way, and the TCE set against the market.
