Overview
RFA Wave Ruler is a Wave-class fast fleet tanker of the Royal Fleet Auxiliary (RFA) of the United Kingdom tasked with providing fuel, food, fresh water, ammunition and other supplies to Royal Navy vessels around the world. Wave Ruler was built by Kvaerner Govan (after 1999, BAE Systems Marine) and launched in 2001. She was accepted into service in 2003 and is the second ship to bear this name in RFA service. Wave Ruler and her sister Wave Knight, were designed to replace Olna and Olwen, two 36,000-ton Ol-class fast fleet tankers which were built at Swan Hunter and Hawthorn Leslie in the 1960s. Wave Ruler was the last tanker commissioned into the RFA until RFA Tidespring became operational in late 2017.
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.
