The RightShip Qi platform uses predictive analytics – a technology that learns from experience to predict future behaviour – to provide customers with the ability to better manage marine risk.

In Qi’s predictive model, which has been independently verified, vast quantities of ever-changing data are analysed by sophisticated algorithms to spot patterns and draw conclusions from data sets too large, diverse and dynamic for analysis with previous technology.

RightShip receive real-time data from over 50 sources, clean it up, master, and remove any duplicates to create our ‘golden record’, which predicts the likelihood that a vessel will have an incident in the next 12 months.

A vessel’s predictive risk rating in Qi takes into account up to nine key risk factors, which interrelate in a unique way in each individual circumstance. Up to six of the most significant risk factors will be considered in a vessel’s rating (including regulator risk, casualties risk, PSC performance, builder risk, size, age, type, DOC PSC performance & continuity risk) together with any of the four positive adjustment factors (an audit, classification, association or a RightShip Dry inspection) that are external to the predictive model.

We’re constantly testing the system predictions against real world outcomes. Incident rates from 2014 and 2015 show that a one-star vessel was up to 20 times more likely to have an incident than a 5 star vessel.


As is the case with all predictive models, RightShip Qi undergoes an adjustment every once in a while, known as a ‘retrain’.

Retraining is a ‘business as usual’ process which helps to preserve the desirable features of the original model, increase performance, and remedy any shortcomings that have been identified while it’s been in use.

A retrain generally occurs every 4-6 months, when the model needs to adapt to changes in input data since the previous training. We don’t do it too often, as we want to ensure that the Qi model is stable, rather than constantly changing; however we do it frequently enough to ensure that the model is up-to-date and accurately reflects the data associated with the current fleet.

RightShip’s focus remains firmly on improving maritime safety standards, and Qi increasingly helps us target those vessels with a high likelihood of having an incident over the next 12 months. While retraining the model assists with this, the practical outcome of a retrain is that a minority of vessel star ratings may move (either up or down): however the vast majority will stay the same.

The following animation provides an overview of the retrain process. If you have specific questions relating to the retrain or changes to your vessel ratings, please contact
