A-FRAMES	Two heavy-duty hydraulically-actuated A-Frames are located on the stern, one facing aft over the stern and the other over the starboard quarter. They are both rated at 15 tons.
CRANES	A Nautilus fully-articulated hydraulic crane is situated on the port side of the fantail. It has 360 degree rotation, and a 2.5 tons capacity at the full extension of 36′.
WINCHES	The coring winch is an electric/hydraulic Northernline Model 3355 EHHOW, located on the main deck aft for stern or starboard quarter heavy-duty operations. Wire length is about 4,000m of half-inch three strand torque balanced wire with a SWL of 6 tons. At mid-range, the drum has 30,000 lbs of line pull at 60m/minute (low range), or 8000 lbs of line pull at 200m/minute (Low range).
	Two CTD/”hydro” winches are located on the starboard side, amidships, on the upper deck. They lead overboard through paired hydraulic-powered gallows, and are used for medium-duty operations. One is a modified Northernline model 3353 EHLOW, SCR/DC drive, spooling 23,000′ of 5/16″ conductor cable (SWL 2 tons). At bare-drum it pulls 3,500lbs at 500ft/minute. The other is a Markey model DESH-5, SCR/DC drive, spooling 30,000′ of 5/16″ conductor cable. It has two speed ranges; at mid-drum on low speed, it pulls 7,000lbs at 298ft/minute; on high speed, it pulls 5,000lbs at 419ft/minute.
