Reduced use of diesel through an optimisation of the water injection pumps. This is one of several actions from a multi-year project to reduce use of diesel. It consists mainly of utilising the water injection pumps periodically when the generators are running on gas. The water injection pumps are stopped when diesel is used. This action was the largest contributor to the reduction of diesel use. The main effect is reduced diesel procurement, but it also leads to significant reduction in NOx emissions and it is a permanent action.

Repsol has implemented this improvement opportunity on some of their installations in 2014.
