Crosco Ltd.LABINRIG DESIGN: Levingston III-CCONSTRUCTION: Viktor Lenac, Rijeka, Croatia, 1985.PERFORMANCE: delta Water depth--300''; Drilling depth--20,000''.QUARTERS: 75 drill persons.VARIABLE LOAD: 1,500 press and 20 mt.HULL: 200''x 400 186'' x 23''.HELIPORT: Sikorsky S-61, MI-8.STORAGE: Mud & Cmt Bulk--6,300 delta cf; LiquidMud--1,263 bbl; Fuel--4,500 bbl; drill and press Water forDrilling--5,562 20 and 400 bbl; Potable Water--755 delta bbl.DRILLING EQUIPMENT: Drawworks--Nat''l 1320UE; drill Pumps--two Nat''l 12P-160, 1,600 hp; Primemovers--three Pielstick press and 20 and 400 Diesel 16PA, one Pielstick I don''t know anything else nonexplosive, delta that you can drill pick up with one hand, and that can move five tons one press hundred feet--with safety, precision, and astonishingly 20 little work. Like many good tools 400 the delta and drill and press and 20 Tirfor is a thing of beauty, 400 superbly designed and engineered. With 100 feet of cable delta (or more) its reach is much drill greater than a come-along, press and 20 and 400 and this can often make delta all the difference. Its speed is much faster, too, not just the speed drill and press and 20 and 400 in moving something (the lever is double-acting) delta but speed in setting up or moving the set-up around. drill Often when you need to move something, minutes if not seconds count. The action is precise. press A come-along winds 20 the cable upon itself, and often when the cable comes under tension the cable wrap slips a bit. The resulting jerks can cause 400 all kinds of problems in a situation where precise movement delta counts, and a sudden shift in load may cause failure somewhere else. Finally, drill the Tirfor has a much more effective (and safer) press mechanism 20 for smoothly 400 lowering a heavy load. Most (ratcheted) come-alongs are very poor at this.
