Composite Risk
Risk Score
Some elevated factors — typically age or a lower-graded flag — but no acute ship-specific flag.
A coverage-weighted blend of the 2 components 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.

Overview
About This Vessel
BOKA Vanguard (formerly Dockwise Vanguard) is a semisubmersible heavy-lift ship owned and operated by Dockwise B.V. Dockwise Vanguard is the largest vessel of her type ever built, and is able to carry cargoes up to 110,000 tonnes. Dockwise Vanguard was designed to move offshore oil and gas facilities, but can also carry other ships and act as an offshore dry-dock facility. As offshore oil and gas facilities have grown in size, Dockwise saw a market for a ship that could carry the largest floating oil rigs to their destinations, reducing time and costs of transportation and allowing rigs to be built economically in a shipyard. In conjunction with Finland-based Deltamarin, they designed a ship called the "type-O heavy-lift vessel", later renamed Dockwise Vanguard following an in-house competition won by Gerry Sarlis and Anthony van Ginkel. In 2014, Dockwise started a feasibility study into a larger successor to Dockwise Vanguard.
