Isnt the derrick supposed to be straight then?
Straight relative to the ship—not always relative to the sea when the ship is underway.
Here is JOIDES Resolution in Barbados, preparing to leave on ODP leg 207 to drill into cretaceous time in order to measure the climate back then.
As I recall, the ugly ship on the left is Star Princess.
#2 is an older picture of JR. Between the helipad and the derrick is the pipe rack. Forward of the derrick are the labs.
#3 is a picture of the ship’s officers…er, no…they are the drilling crew from the Philippines.
#4 is the scientific party—29 members from nine nations.
