Imagine an engineer on a ship who is faced with a not-uncommon decision.

The load on the vessel’s auxiliary engines has dropped to a point at which one can be taken offline, reducing fuel consumption, but it is also coffee time.

Will she grab a cup of coffee or take the engine offline?

The engineer’s decision is one that technology start-up Signol, whose software brings behavioural science to shipping, believes it can influence, helping crews implement strategies to optimise fuel consumption and reduce emissions.
