10 Rig components Mast and substructure ZPEC designs and manufactures different kind of masts and substructures, the erections are synchronously erected, continuously erected, dual erected, encasement type, self-erected, vertically erected, packaged type, and the tower type for offshore purpose. Synchronously erected type: Mast legs root on a base with drawwowks installed on rear floor. At low level, mast and substructure are inclined forward. The first section of mast and top right and left of substructure are connected with horizontal beam. At the time of mast rising, the connection joints of top right and left drive substructure to rise. All erection sequence need no change of wireline and non-stop, thus save erection time. 20Zhongman Petroleum and Natural Gas Group Co., Ltd., Zhongman Petroleum and Natural Gas Group Co., Ltd., 21

11 Continuously erected type: Mast legs root on a base with drawwowks installed on floor. At low level, top side inclines backward, top of substructure connected with base by 8 pins. Mast rises to its position through wireline driven by drawworks. When it is on its position the 8 pins disassembled between substructure top and base, and no change of wireline the whole rig is erected. Vertically erected type: Mast legs root on substructure base and drawwowks is used to raise mast. The substructure is raised vertically and driven by drawworks or independent hydraulic system. When it is erected to its position the A frame is to be connected with mast legs. This erection system can meet the requirement of height adjustment to adjust BOP stack at different formation. This also meets the requirement of moving with full strings on it. Dual erected type: Mast legs root on a base with drawwowks installed on floor. At low level, top side inclines backward. Dual erected type uses two wirelines to raise, respectively, the mast and substructure. Firstly, one wireline is used to raise mast to its position and then disassembling the wireline from the mast and thread it to substructure wiring system to raise substructure. As the substructure is raised after mast being erected, it is regarded as revolving erection type. Tower type: This type is suitable for jack-up platform. It has working height of 49 to 52 meters. The mast is supported with H beam structured tower. The area is square with whole rig being as pyramid interspaces. Main parts consist of four sheets of spread out frames constructed with high strength alloy steel connected with locked bolts. The oblique plane on drawworks side is constant from floor up to crown blocks and the other sides changed at monkey board in order for arrange strings. Two guiding tracks are equipped for top drive and for client option equipped with pipe conveyor, string racking system, dead line clamps. Jacks are fixed at the ends of mast legs for leveling and adjustment. All members on steel structure are hot zinc soaked treatment to meet corrosion prevention requirement at marine condition. 22Zhongman Petroleum and Natural Gas Group Co., Ltd., Zhongman Petroleum and Natural Gas Group Co., Ltd., 23
