Crane castle

Ed Dever, OSU

For OOI Endurance mooring operations, the team relies on the excellent lifting equipment offered by the R/V Sikuliaq.  Here a recovered surface buoy (about 20 ft tall and 10,000 lbs) is being repositioned using the red starboard crane while science party and deck crew keep things under control with tag lines controlled by air tuggers.  You can see why the crane’s home is nicknamed the castle.
