It is no surprise that most small claims are caused by small human errors. You might expect, therefore, that most really large claims would result from major human errors. They do not! They, too, are caused by minor errors. I was impressed by the depth of analysis in this year’s UK P&I Club Analysis of Major Claims and note this finding above all others: there is no discernible difference between the origins of small and large claims. It follows that the only reliable way of avoiding catastrophic loss is to operate in a way that minimises the risk of any kind of loss. Nautical Institute studies on accident prevention certainly confirm this.
