TZ301-1自升式钻井平台 平台用途及适用范围 Purpose and Applicability of Platform 本平台是一座海上石油天然气勘探开发作业的钢质非自航自升式钻井平台，适用于泥砂质或淤泥质海床作业，最大工作水深可达122m（400ft），钻机能力9000m（30000 ft），具备深井探井和大位移丛式井/水平井钻井功能及试油辅助功能。 This platform is a non-self-propelled self-elevating drilling rig used for offshore oil and natural gas exploitation and development operation, with the max. operating water depth 122m (400 ft), the drill capacity of 9000m (30000 ft), provided with such functions as exploring of deep well/ cluster well/ horizontal well cementation and auxiliary oil test, etc. 总体描述 General Description 平台船体近似为三角形箱型结构，主尺度：型长×型宽×型深=70.27 ×72.0× 9.5（m）。 The hull of the platform is triangle box-type structure. The main dimension of the hull is 70.27m long, 72.0m wide, and 9.5m deep. 平台艏艉设有三个三角形桁架式桩腿，桩腿下端带有桩靴。 The platform is arranged with three triangle truss work legs, each fitted with a spud can at its lower end. 船体结构分为主甲板、中间甲板、机械甲板、和底板四层，主龙骨摆布呈2纵5横型式。纵横舱壁将船体分为若干个舱室：船体周边舱室设为压载舱、钻井水舱、盐水舱、基油舱等；舱内机械甲板和中间甲板上布置有主发电机组、主配电间、泥浆泵、泥浆池及其它辅助机械设备；双层底布置有燃油舱、钻井水舱、淡水舱、舱底水舱等。 Hull structure is divided into three parts with four decks: main deck, intermediate deck, machinery deck, and bottom plate. Longitudinal and transversal bulkheads divide the hull into several spaces. The ballast tanks, drill water tanks，brine tank, base oil tank are arranged at the space of the surrounding of triangle hull; main engine room, main switchboard room, mud pump room, mud pit and other auxiliary machineries, etc. are arranged on the mechinery deck and tween deck; fuel oil tank, potable water tank, bilge water tank, etc. are arranged in the double bottom. 主甲板按功能分为艏部生活区、艉部作业区、中间堆场区三部分。悬臂梁坐落在主甲板上，安装在纵向主龙骨舱壁顶部；悬臂梁顶部中前部铺设有钻杆堆场，艉部架设有钻台底座横向移动导轨架，钻台底座安装在横向轨道上部；悬臂梁和钻台可实现纵、横方向移动，平台在一个位置可钻多口井。 The main deck is divided into three parts: living quarters at foreship, working area at aft-ship, and stack area at mid-ship. Cantilever is located on the main deck; drilling pipe rack and the guide rail for drill floor foundation transverse moving are arranged
