Technical Specifications
Overview
USS Merrimack (AO-179) was the third ship of the Cimarron-class of fleet oilers of the United States Navy. Merrimack was built at the Avondale Shipyards in New Orleans, Louisiana starting in 1978 and was commissioned in 1981 for service in the Atlantic Fleet. Total cost for the ship was $107.1 million. She was last homeported at Norfolk, Virginia. Between 1989 and 1991 Merrimack was "jumboized", meaning that, after cutting the ship into two sections after about a third from the bow, a 35.7 m long section was added to increase the fuel load. Merrimack was decommissioned on 18 December 1998 and struck from the Naval Vessel Register on the same day. Her title was transferred to the Maritime Administration. She was scrapped in Brownsville on 5 June 2013.
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.
