So, they would have a crew report to base A, and then turn over at another base with team B? So, the ship is deployed, but not all of the crew?
Is that correct?
Sort of, but there are 2 full crews, one designated "Blue", the other "Gold". They deploy with a full crew, then swap crews during an inport period, during which they perform maintenance. While the Blue crew is underway, working 12-16 hour days, 7 days a week, the Gold crew is getting some time off, doing shore based training and generally living a pretty normal life.
