Description

钢板和混凝土复合结构的单元罐、 单元组罐及海上平台
技术领域
本发明涉及一种钢板和混凝土复合罐壁的储罐 (单元罐、 单元组罐) , 用于在水 下储存工业液态产品, 如原油、 成品油、 LNG、 LPG等, 及以所述复合罐壁的储罐为基础 的海上储液、 钻井和生产设施。 背景技术 针对申请人先前两个 PCT发明专利申请: "液体储存、 装卸装置及以其为基础的海 上钻井和生产设施" (申请号: PCT/CN2009/000320 ) 和 "压载海水与液化天然气或液 化石油气的等质量流率置换流程和多功能海上基地" (申请号: PCT/CN2009/001008 ) 存在的不足, 本发明公开了一种钢板和混凝土复合结构的储罐, 并及以其为基础, 改进 了上述两个专利申请所涉及的海上平台等海上设施。
为了解决现行水下湿式储油和干式储油污染环境、 操作重量变化大等缺点, 本申请 人在先前 PCT发明申请 "液体储存、装卸装置及以其为基础的海上钻井和生产设施"(申 请号: PCT/CN2009/000320 ) 中, 披露了一种新型水下储液流程, 即 "密闭气压连通式 压载海水和储液等质量流率置换流程"。 该流程的储液舱和海水压载舱密闭, 两舱液体 的上部预充一定压力的氮气, 氮气通过两舱顶部的管道和闽门连通成为同一个压力系 统; 两舱中任何一舱的液体排出, 另一舱必有等质量的另一种液体流入, 以保证储液在 装卸的过程中系统的操作重量不变。 密闭带压氮气的功能一是作为液体上方的覆盖气, 二是在两种液体间实现压力能的传递。氮气在系统装卸的过程中既不需要补充, 也没有 对外排放。 流程的等质量流率置换通常通过相关的装载泵和外输泵联动来实现, 其中压 载海水或储液首先是依靠舱内氮气的压力能被压送至外输泵的进口。该专利申请还披露 了与上述流程配套的组合式储液罐, 以及以该储液罐为基础的海上浮式和固定式平台, 用于海上油田的钻井、 生产和原油的储存, 但不涉及液化天然气 (英文缩写: LNG ) 等 的生产和储存。 该申请所涉及的固定式设施均采用 "小水下重量坐底"技术, 即该设施 的操作重量等于或略大于设计高水位时的浮力 (排水量) , 该设施海床坐底固定, 依靠 长桩或吸力桩抗滑移、 抗倾覆。 该申请的组合式储液罐在多数工况下为内压容器, 采用 现有的混凝土技术设计建造。 为了解决 LNG在水下储存的难题, 本申请人在先前 PCT发明专利申请 "压载海水与 液化天然气或液化石油气的等质量流率置换流程和多功能海上基地" (申请号: PCT/CN2009/001008 )中, 披露了一种新型水下储存 LNG和液化石油气(英文缩写: LPG) 流程。该流程的储罐中的海水压载舱的海水和 LNG或 LPG储罐中的 LNG或 LPG在装卸过 程中实现等质量流率置换, 以保证系统操作重量不变。 流程的等质量流率置换通常是通 过相关的装载泵和外输泵联动来实现的。 在装卸的过程中, LNG或 LPG储罐内液体上方 的饱和气体来自或返回多功能基地上部设施流程的不同位置,海水压载舱内部海水上方 的气体来自或返回多功能基地上部设施流程上游的不同位位置。该专利申请还披露了与 上述流程配套的卧式长圆筒形组合式储液罐, 以及以该储液罐为基础的海上浮式和固定 式设施, 用于海上气田的钻井、 生产、 天然气液化和储存, 但没有涉及原油的储存。 该 申请卧式长圆筒形组合式储液罐采用现有的混凝土技术设计建造。
然而众所周知, 混凝土结构的特点是抗压强度远远大于抗拉强度; 因此混凝土储罐 适合承受外压而非内压。 目前, 采用混凝土建造的内压储罐的技术方案主要有两种: 预 应力钢筋混凝土结构和双钢板混凝土 (BI-STEEL ) 结构。 从纯理论角度而言, 现有的两 种方案用于内压容器不存在技术问题;但是,为了承受内压引起的作用于罐壁的拉应力, 必须采取很多特殊的技术措施, 使得混凝土储罐的设计和建造都面临了许多挑战, 大大 增加了施工建造的难度和复杂性, 延长了工期, 增加了造价。 上述两个申请无疑均存在 按现有技术建造混凝土内压容器的缺点。
上述第一个申请 (申请号: PCT/CN2009/000320 ) 还存在以下不足: 1.该申请垂直 "上下罐"式和水平 "左右罐"式组合罐的储液舱的筒壁外部为大海, 一旦筒壁破损, 储液将造成污染。 2.该申请固定式组合罐及其应用 -—固定式平台和固定式人工岛均采 用小水下重量坐底加桩基础抗滑移和抗倾覆, 排除了重力式基础; 其中长桩需要打桩, 没有提出可行的 "自安装"方案。 3.该申请的浮式平台和浮式人工岛的组合罐结构形式 和尺度对于浮体水动力性能影响极大, 该申请对于这些因素, 如浮式平台组合罐相关主 要尺度之间的优化关系, 部分构造优化设计, 均没有提出建议。 此外, 该申请对于组合 罐和平台如何在轻载状态尽可能减小吃水, 以便平台能够采用坞深 7〜9米干坞建造, 没有予以充分的关注。
上述第二个申请(申请号: PCT/CN2009/001008 ) 同样存在上述第 1和第 2项不足, 同时还存在以下不足: 由于卧式长圆筒形组合罐由多个首尾相接的多个组合罐组成的, 每个组合罐因内压造成的轴向伸长叠加后的总伸长是决不能忽视的, 该申请没有针对水 平卧式组合罐的特点提出结构连接优化方案。 发明内容

请参考图 1至图 4, 分别为本发明钢板和混凝土复合结构的单元罐的结构示意图; 图 1的 A-A向的剖面图;图 1的 B部分的局部放大图;以及图 1的 C部分的局部放大图。 如图所示, 本发明的钢板和混凝土复合结构的单元罐 1, 包括:
混凝土刚性整体外罐 (以下简称 "混凝土外罐 2 " ) , 该混凝土外罐 2包括混凝土 外罐筒体(以下简称 "外筒体 3 " ), 设置在外筒体两端的混凝土结构或钢结构或混合结 构的封头和连接结构 4; 封头包括拱形封头和平板封头 (如图 3和图 4所示) 。 本发明 所述混凝土结构包括一切以混凝土为主要建筑材料的结构, 如钢筋混凝土结构、 预应力 混凝土结构、 钢骨混凝土结构、 钢板混凝土结构 (BI-STEEL)、 纤维增强混凝土结构等。
钢制内罐 5, 位于混凝土外罐 2的内部, 包括圆筒形钢制容器 (以下简称 "内筒体
6 " ) , 设置在内筒体 6两端的外延结构, 内筒体 6通过外延结构与外筒体 3相连接形 成一个整体结构。 在一个可选的实施例中, 外延结构为内筒体 6直接向两端延伸形成的 圆筒形外延结构 7 (如图 3和图 4所示) , 在另一可选的实施例中, 外延结构为内筒体
6向两端延伸出的支腿外延结构 8 (如图 5所示) 。
由钢制内罐 5与混凝土外罐 2之间的空隙(包括内筒体和外筒体之间的空隙和钢制 内罐 5的封头与混凝土外罐 2的封头之间的空隙) 构成的隔离层 9, 在隔离层 9内填充 有隔离介质, 如图 3、 图 4所示。 隔离介质为惰性气体或液体或惰性气体加柔性固体材 料或液体加柔性固体材料,其主要功能为避免或降低钢制内罐 5与混凝土外罐 2之间因 内外压力造成的罐壁应变和应力相互直接传递的可能性。
本发明所采用的钢板和混凝土复合结构的单元罐, 用于在水中储存工业液态产品, 如原油、 成品油、 LNG、 LPG等; 本发明的单元罐充分利用混凝土材料抗压性强, 钢材抗 拉性强的物理特性, 使单元罐的钢制内罐的钢板罐壁和混凝土外罐的混凝土罐壁, 分别 承受拉应力和压应力, 从而大幅度提高了单元罐的结构强度, 并且具有施工建造的难度 低和复杂性小, 工期短, 造价低、 维护简单等优点。
作为本发明的钢制内罐 5与混凝土外罐 2的连接方式的一种可选的实施例,钢制内 罐 5的外延结构 7的一端固定连接于混凝土外罐 2—端的连接结构 4上, 形成固定式连 接结构 20 (如图 3所示); 外延结构 7的另一端滑动连接于混凝土外罐 2另一端的连接 结构 4上, 形成滑移式连接结构 21 (如图 4所示) , 使钢制内罐 5能在混凝土外罐 2 内沿中心轴线滑移, 为此需要在混凝土外罐的连接结构 4内设置滑移式结构预留膨胀空 隙 22,其目的主要是避免约束钢制内罐因内压而产生的轴向伸长。通过固定式连接结构
20和滑移式连接结构 21使得混凝土外罐 2、 钢制内罐 5和隔离层 9形成一个刚性整体 结构。
作为本发明的钢制内罐 5的一种可选的实施例,钢制内罐 5包含至少一组结构对称 的储液舱 10和海水压载舱 11的组合式储液罐 (以下简称 "组合罐" ) 。 组合罐在储液 装卸的过程中借助压载海水的调载, 可实现操作重量的调整、 乃至实现操作重量不变。 每组储液舱 10和海水压载舱 11有三种排列形式:垂直上下式、水平左右式和罐中罐式。
垂直上下式, 即钢制内罐 5的内筒体 6的内部被一个封头上下一分为二, 形成两个 舱, 一个为储液舱, 另一个为海水压载舱; 或者如图 1所示, 内筒体 6的内部被两个封 头上下一分为三, 形成三个舱, 一个大舱为储液舱, 通常在中部, 另两个为海水压载舱, 通常在上下两端, 两个海水压载舱通过管道连通在一起 (图 1中没有示明) , 形成实质 的一个海水压载舱。
水平左右式, 即水平卧式钢制内罐 5的内筒体 6的内部被两个封头左右一分为三, 形成三个舱, 一个中部大舱为储液舱, 左右两端两个小舱为海水压载舱, 通过管道连通 在一起、 形成实质的一个海水压载舱。
罐中罐式, 即储液舱 10位于海水压载舱 11的内部, 二者具有同一条中心轴线。 作为本发明的钢制内罐 5的一种可选的实施例, 钢制内罐 5内不设海水压载舱, 钢 制内罐 5即是储液舱。 为了防止钢罐的腐蚀, 单元罐 1内的钢制内罐 5与带腐蚀性的液体, 如海水等接触 的表面均涂有保护性的涂层。
本发明的钢制内罐 5, 其中的储液舱 10用于储存各种工业液体, 如原油、 成品油、 LPG、 LNG等。 进一步的, 储液舱 10的舱壁为钢制单舱壁或复合舱壁, 以适应不同工业 液体储存的特点。例如,储存低温液体如 LNG的储液舱的罐壁从外到内通常为: a、 16MnR 钢罐壁, b、 低温隔热材料, 如注氮气正压珠光砂等, c、 耐超低温的钢材, 如耐低温的 奥氏体不锈钢 0Cr l8Ni9制成的内罐壁。 内外筒之间的支撑采用耐低温且隔热性能较好 的环氧玻璃钢与 0Cr l8Ni9钢板组合结构。 储存带有较高温度储液, 如热原油的储液舱 的舱壁可加设保温层。
如前所述, 隔离层 9的主要功能是避免钢制内罐 5因内应力造成的表面应变和应力 直接接触传递至刚性整体混凝土外罐 2上。隔离层 9的系统压力是可调整大小的和可安 全释放的。 该系统压力可根据需要, 按照混凝土外罐 2所受外部海水静压力和钢制内罐 5所受内部压力进行设定,目的在于降低作用于混凝土外罐 2和钢制内罐 5的压力载荷。 当隔离层 9的系统压力与单元罐外部海水的压力相等(可用多种方法来实现, 其中最简 单的方法是将隔离层与外部海水连通)时, 单元罐的混凝土外罐所承受内部和外部的压 力平衡, 这对于处于深水的储罐的结构设计具有十分重要的意义。 以一个罐底位于水下 1000米深、 储存原油的单元罐为例, 单元罐内部的钢制内罐高 40米, 需要借助钢制内 罐内部压缩氮气的压力将原油送至水面以上 20米高处,压缩氮气的最小压力为 1020米 高的油柱, 据此可设定氮气压力为 102个大气压, 单元罐的隔离层与外部海水连通, 最 大的外部静水压位于罐底, 约为 100个大气压, 最小的外部静水压位于罐顶, 约为 96 个大气压,则钢制内罐可按内压约为(102-96 ) =6个大气压而非 106个大气压进行设计, 混凝土外罐内外压力相等, 不需要按压力容器进行设计。 深水储液舱和海水压载舱的储 液和海水不用泵而依靠气体的压力能实现外排, 可避免采用深水水下泵, 降低投资和操 作维修费用, 这是本发明单元罐的优点之一。
对于带有海水压载舱和和储液舱的单元罐,储液在装卸的过程中需要与压载海水实 现等质量流率或不等质量流率置换。 对于等质量流率置换的普通储液, 本发明优先采用 "密闭气压连通式压载海水和储液等质量流率置换流程" 。 对于等质量流率置换的 LPG 和 LNG,本发明优先采用"压载海水与液化天然气或液化石油气的等质量流率置换流程"。 如图 7、 图 8, 分别为本发明的正方形蜂窝状排列的立式单体组罐的立面图和图 7 的 G-G剖面图。 本发明还提出了一种海上储存工业液体的单体组罐 12, 该单体组罐 12 由至少两个上述单元罐 1 依次通过连接结构 4 的并联或首尾串联固定连接成为一个整 体, 形成了浮式或固定式海上储存工业液体的单体组罐 12。 当然单体组罐 12也可以由 一个单元管 1单独构成。 单体组罐 12内的单元罐 1呈竖立设置形成立式单体组罐, 或 者单体组罐 12内的单元罐 1呈平卧设置形成卧式单体组罐。单体组罐 12的顶部潜没在 水下或伸出水面。 单体组罐 12根据在海水中的定位状态分为浮式单体组罐和固定式单 体组罐, 浮式单体组罐通过系泊腿锚泊固定在海床上, 固定式单体组罐通过吸力桩或长 桩或重力基础固定在海床上, 或采用桩和重力基础结合的方法固定在海床上。
进一步的,至少两个上述单元罐 1通过连接结构 4并联且呈竖立设置构成立式并联 单体组罐。 如图 7、 8所示, 立式并联单体组罐包括主体 24和连接在主体 24下部的裙 边底舱 25, 主体 24由 9个 (代表两个以上) 单元罐 1紧密并联成矩形蜂窝状, 或其它 形状, 如六边形、 多层同心圆形等, 通过各单元罐 1上下两端的混凝土外罐的封头和连 接结构 4连接为一个整体结构。 同时, 单元罐混凝土壳的外筒体 3之间也进行辅助性的 连接。 图 7中 9个单元罐上下两端的混凝土外罐的封头和连接结构 4连接形成了矩形扁 平柱形连接结构 13。主体 24的根部两侧为分列式裙边底舱 25。请一并参考图 9和图 10, 图 9所示的海上平台的单体组罐 12也为并联立式单体组罐, 同样包含 6个单元罐组成 的主体 24和环绕式裙边底舱 18;二者可以直接连接成一体,也可以如图 9和图 10所示 存在径向间隙, 环绕式裙边底舱形成为一个独立的 "环" , 通过连接构件 19相连接, 专用于浮式设施。 如图 10所示, 环状裙边底舱 18为圆环形裙边底舱, 也可为正多边环 形裙边底舱。正多边环形裙边底舱是由多个长度相等的长条形裙边底舱按正多边形连接 在一起, 长条形建造难度低于圆弧形。 如图 7和图 9所示, 裙边底舱的截面通常为矩形 或多边形, 底部与主体的底部齐平, 高度远小于主体的高度, 在位状态 (IN-PLACE) 时 顶部潜没在水下。 裙边底舱内部空间可根据需要设置储液舱、 海水压载舱、 固定压载舱 之中的一种或多种。 裙边底舱的功能在于为建造和拖航增加浮力、 调整重心的位置并增 加重量, 为浮式单体组罐增加附加质量和阻尼、 改善水动力性能, 为固定式单体组罐改 善海底冲刷状况。
将上述立式并联单体组罐的主体 24水平放置, 即形成卧式并联单体组罐。
如图 11〜图 16所示, 卧式单体组罐的多个单元罐 1的混凝土外罐的筒体 3首尾相 接形成一个单一的水平长圆筒形卧式单体组罐。每个单元罐 1内部的钢制内罐 5两端均 为圆筒形外延结构。 当串联相邻的两个单元罐的连接端均为固定式连接结构 20时 (参 见图 11、 12 ),所述两个单元罐钢制内罐的圆筒形外延结构可焊接为一体(参见图 12 ), 再与混凝土壳的连接结构 20固定 (参见图 11 ) ; 当串联相邻的两个单元罐的连接端均 为滑移式连接结构时(参见图 13、 14) , 或一个为滑移式连接结构、 另一个为固定式连 接结构时(参见图 14、 15 ) , 两个钢制内罐 5圆筒形外延结构的一个筒体可插入另一个 筒体内, 再同时分别与混凝土壳的连接结构 21实现滑移 (参见图 14、 16 ) 或固定连接 20 (参见图 16 ), 使得每个滑移式外延结构可同时在混凝土壳的连接结构和另一个外延 结构的筒体内 (或筒体外) 滑移 (参见图 13、 14和图 15、 16 ) 。
将上述卧式串联单体组罐垂直放置, 即形成立式串联单体组罐。
进一步的, 如图 6所示, 为本发明的密闭式钢管桩结构图。 固定式单体组罐的长桩 基础为密闭式钢管桩 26,密闭式钢管桩 26包括圆钢管 31及其顶部焊接密闭的封头 30、 封头 30上安装放气闽 28、 进气闽 29和进水闽 27。 钢管桩 26在单体组罐拖航前插入单 体组罐的桩套筒内并临时固定,海上压桩时借助单体组罐加水压载后的重力将桩压入海 床。 安装步骤为: 1 ) 单体组罐漂浮拖航、 至油田现场后就位和定位, 打开放气闽 28, 解除桩 26的临时固定、 靠自重下放密闭式钢管桩入泥; 2 ) 将密闭式钢管桩 26与单体 组罐 12再次临时固定, 加压载水至单体组罐内使之下沉压桩, 根据对每根桩的压桩力 的计算结果, 按对称的两根桩为一组, 决定每次压桩的数量, 同时注意根据压桩过程中 单体组罐的水平度, 及时调整不同方位的单元罐的压载海水量; 3 ) 罐底下沉至海床后 再次解除桩的临时固定, 排水使单体组罐上浮; 4)重复上述压桩-上浮-再压桩的步骤, 当桩到达设计入泥深度后让罐体海床坐底、 再将桩与罐体正式固定; 5 ) 打开进水闽 27 排气注水、 水满后关闭排气闽 28和进水闽 27, 这样做法的目的是压桩完成后土塞的下 端均能够承载, 排出单体组罐 12内多余的压载水, 完成海上压桩。
现有桩基固定的海上设施需要搬迁或拆除时, 必须解除基础长桩对设施的固定, 通 常需要将桩进行切割。 本发明采用上述密闭式钢管桩 26的桩基固定式单体组罐, 其中 密闭式钢管桩 26可依靠单体组罐 12排水上浮实现拔桩, 再将单体组罐湿拖撤离。 拔桩 的步骤为: 1 )排除单体组罐 12内的液体和固定压载、 打开放气闽 28、 实现单体组罐上 浮和初始拔桩; 2 ) 单体组罐 12浮至水面、 向密闭式钢管桩 26内注满水后关闭注水闽 27和放气闽 28、解除桩的固定,密闭式钢管桩 26内的水柱可保证长桩不会因自重下沉; 3 ) 向单体组罐 12内加压载水使之再次下沉坐底, 将密闭式钢管桩 26与罐体 12临时固 定; 4) 重复上述排载上浮拔桩 -桩内注水防下沉、 解除桩的固定-压载坐底并临时固定 长桩-再次排载上浮拔桩直至桩完全拔出; 在桩拔至海床浅表层时, 还可通过进气闽 29 注气, 靠气压和排水增加的浮力将桩拔出并提升至所需的位置; 5 ) 将桩与罐体固定, 完成拔桩作业。
这样, 在海上压桩和海上拔桩时, 借助所述单体组罐加水压载后的重力, 通过控制 所述放气闽、 进气闽和进水闽的启闭, 使得所述钢管桩压入海床和拔桩作业。 本发明还提出了一种海上平台,用于海上油气田的开发、钻井、石油和天然气生产、 天然气液化, 液体储存, 包括浮式和固定式两种形式。 如图 9所示, 这两种形式的海上 平台均由三部分组成: 1 ) 水下储罐, 它是一个或多个漂浮在海上或固定在海床上的如 上所述的单体组罐 12, 用于储存平台的产出液体, 如原油、 LPG和 LNG、 海上天然气转 化为液体(GTL) 的产品如甲醇等; 单体组罐 12的顶部潜没在水下或伸出水面; 对于包 含钻井或平台井口设施的海上平台,海上平台的单体组罐 12设有上下通透的月池 14; 2 ) 上部设施 15, 位于所述单体组罐 12上方的水面以上, 通过支腿结构 16与单体组罐 12 相连接, 上部设施 15包括钻井设备、油气生产和储运设备、公用系统和生活设施等; 3 ) 使海上平台漂浮定位在海上的定位系统, 包括系泊腿系统、 动力定位系统或二者的组合 (图 9没有示明) ; 或使海上平台固定在海床上的基础结构, 包括桩式基础, 即长桩基 础或吸力桩基础、 重力式基础或桩式基础和重力式基础的组合。
海上平台可以有多种结构形式,作为本发明的海上平台的一种实施例,如图 9所示, 海上平台为海上浮式人工岛, 其特点是浮式单体组罐 12的罐顶高出水面一定高度。 如 果浮式单体组罐 12的罐顶潜没在水下一定深度, 支腿结构 16具有足够的水线面面积, 以保证浮式平台的稳性, 则形成了带水下储罐的浮式平台。 如果单体组罐 12坐落并固 定在海床上, 当单体组罐 12 的顶部高出水面一定高度, 该海上平台即成为固定式人工 岛; 当单体组罐 12 的顶部潜没在水下一定深度, 该海上平台即成为带海底储罐的固定 式平台。
海上平台的储液和压载海水可采用外输泵, 如泵舱泵或深井泵或外置的水下泵, 直 接外输; 或依靠不含氧气的压缩气体, 如氮气、 天然气的压力能外排至水面以上的外输 泵的入口, 再由外输泵接力外输。 前者的优点是储液舱和海水压载舱内部压力小, 舱壁 钢材用量少、 造价低, 缺点是舱内系统复杂, 维修工作量大, 泵的造价和操作费用高。 后者正相反, 舱内压力高、舱壁钢板厚, 接力的外输泵可采用常规的离心泵, 系统简单、 维修工作量小。 本发明推荐采用气体压力能加外输泵的方案。 储液外输的过程中可根据 需要, 与压载海水进行等质量流率或非等质量流率置换, 或不与压载海水进行置换。 等 质量流率置换优选采用背景技术部分提及的"密闭气压连通式压载海水和储液等质量流 率置换流程"和 "压载海水与液化天然气或液化石油气的等质量流率置换流程"。 等质 量流率置换流程可保证储液在装卸的过程中平台的操作重量不变,保证浮式平台的吃水 深度不变, 这对于安装了干式井口的浮式平台十分重要。 对于不需要安装干式井口的浮 式平台, 储液外输的过程中可采用与压载海水进行非等质量流率置换, 或不与压载海水 进行置换, 依靠浮式平台装载量-吃水自动调节机制实现装载和浮力的平衡, 其优点是 大大增加钢制内罐 5的储液舱 10的容积, 以增加平台的储液量。
如图 9, 图 10所示, 海上浮式平台的水下储罐为立式并联单体组罐 12, 按单层或 多层同心圆紧密排, 同心圆的圆心处可设置或不设中心单元罐 (图 10所显示的是 6个 单元罐按圆形紧密排列所形成的单体组罐, 不设中心单元罐) , 上下两端混凝土壳的连 接结构连接并扩展为一个扁平圆柱 13,其直径等于外层单元罐投影外切圆的直径,所述 不设中心单元罐的立式单体组罐的上下扁平圆柱式连接结构的中心为圆孔洞,所述圆孔 洞的直径等于空缺的中心单元罐筒体的外径, 形成带上下通透月池 14的立式单体组罐; 所述立式单体组罐 13的底部受波浪影响很小的深度。
进一步的,海上浮式平台的立式并联单体组罐 12,其中上端和下端的扁平圆柱连接 结构 13的底部和顶部平面分别向下和向上隆起形成圆锥面 17, 与立式单体组罐外层单 元罐筒体相交形成相贯线, 其目的在于降低波浪水质点向下和向上绕射所产生的波浪 力; 锥面的圆锥角不大于 45度 (参见图 9 ) 。
进一步的, 浮式海上平台的立式并联单体组罐的主体 24下端的环绕式裙边底舱 18 为圆形或正多边形环状裙边底舱, 所述环状裙边底舱 18底部与所述立式单体组罐的下 端扁平圆柱式连接结构 13 的底部齐平, 圆形或正多边形环状裙边底舱的径向截面为矩 形, 截面宽度不小于所述扁平圆柱式连接结构半径的 0. 3倍, 截面高度与宽度之比不小 于 0. 35,裙边底舱通过多个均布的连接构件 19固定连接在所述扁平圆柱式连接结构 13 上。 请注意, 图 9所示连接构件 19仅为示意性, 实际应用时该构件应通过设计和计算 确定其形式和结构。 环状裙边底舱与扁平圆柱的径向最小间隙不小于 0. 3米, 裙边底舱 顶部处于受波浪影响很小的深度, 这一深度在南中国海通常不小于 30米。 裙边底舱内 的空间可根据需要设置储液舱、海水压载舱、 固定压载舱(为了简化, 图 9没有示明)。 对于系泊腿的导缆器位于环形裙边底舱 18上方的浮式平台,在圆环形裙边底舱 18内径 系泊腿穿过的部位开有缺口, 即系泊腿通道 22, 以确保阻系泊腿在运动的过程中不会碰 撞裙边底舱; 或将圆环形裙边底舱 18在缺口处完全断开成为断口, 形成多个均布的裙 边底舱。裙边底舱有三个重要的功能: 一是通过加注固定压载,调整平台的重心的位置。 二是增加所述浮式海上平台的附加质量和阻尼, 改善水动力性能。 三是在建造和拖航过 程中提供足够的浮力和水线面面积, 以保证平台建造完成后能够以较小的吃水深度(如
7〜9米) 起浮, 以及拖航时浮性和稳性的要求。 裙边底舱 18和裙边底舱连接构件 19 用钢结构或钢筋混凝土结构或混合结构建造。
与申请人先前 PCT/CN2009/000320发明专利相比, 经过以上优化, 本发明浮式平台 具有 "本质稳定 (INTRINSIC STABILITY) " 的特性, 即在恶劣海况条件下浮体的运动 响应非常小; 这是由于其固有周期加大, 例如垂荡周期已从大于 20秒增至大于 30秒, 横摇和纵摇的回转半径加大、 运动阻尼增加、 而波浪荷载并未因此增加多少, 使得本发 明浮式平台的水动力性能优于现行的 SPAR平台。
进一步的, 浮式海上平台的水下储罐为两个潜没在水下、 平行、 且保持一定距离的 卧式串联单体组罐,通过位于单体组罐两端的水平连接板和中间部位的多个水平连接杆 连接成为一个整体。两排多个支腿连接所述卧式单体组罐的多个单元罐的混凝土外罐的 筒体连接形成一个单一的水平长圆筒, 形成长圆筒形卧式单体组罐。 长圆筒形卧式单体 组罐内部的钢制内罐两端均为圆筒形外延结构。当相邻两个钢制筒体的外延结构均为固 定式外延结构时, 所述两个圆筒形外延结构可焊接为一体, 再与混凝土壳的连接结构固 定(参见图 11、 12 ) ; 当相邻两个钢制筒体的外延结构均为滑移式外延结构时, 或一个 为滑移式外延结构, 另一个为固定式外延结构时, 所述两个外延结构的一个筒体可插入 另一个筒体内, 再同时分别与混凝土壳的连接结构实现滑移或固定连接, 使得每个滑移 式外延结构可同时在混凝土壳的连接结构和另一个外延结构的筒体内 (或筒体外)滑移 (参见图 13、 14和图 15、 16 ) 。
