375 technical crew have contributed; 217 chief engineers, 80 second engineers, 21 third engineers and 41 ETO/AVIT. Overall, many more engineers are on rotation than captains. We see that 56% of chief engineers, 65% of second engineer and 57% of third engineers are rotational along with 83% of ETO/AVIT engineers which is by far the highest proportion in the technical team. It can be seen perhaps surprisingly that salaries for ETO/AVIT remain relatively constant irrespective of the size of the vessel. To compensate, perhaps, they are the category that most benefit from rotation.
