Overview
The Sovereign is a large sea-going tugboat owned and operated by Royal Boskalis Westminster N.V. The vessel is powered by conventional propulsion and was built as a multi-purpose anchor handling tug supply vessel. It was christened on 27 August 2003 as Anglian Sovereign. The vessel was part of the fleet of Emergency Towing Vessels that operated on behalf of the UK's Maritime and Coastguard Agency. On 3 September 2005, Union Sovereign ran aground off Oxna island in the Scalloway Islands while conducting hydrographic surveys. No injuries occurred but the vessel lost approximately 84 tonnes of gas oil and was severely damaged. A 2006 official report found that the shipmaster's consumption of alcohol and several other negligences on board had been the cause of the incident. In 2007, ownership transferred to JP Knight, which purchased the initial owner, Klyne Tugs of Lowestoft.
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.
