The total order book at the end of the review period amounted to EUR 6,166 million (5,100), an increase of 21%. The Services order book totalled EUR 1,878 million (1,220), which is 54% higher than at the same time last year thanks to the increased demand for exhaust gas cleaning retrofit projects and continued interest in long-term service agreements. For service agreements, only the expected net sales for the next 24 months are included in the Services order book. The Energy Solutions order book was stable at EUR 1,871 million (1,871), while the Marine Solutions order book increased by 20% to EUR 2,417 million (2,009).
