大吨位上部组块连续提升系统的试验装置Test device for continuous hoisting system of large tonnage upper block

技术领域technical field

本发明涉及试验装置，尤其涉及一种用于大吨位上部组块连续提升系统的试验装置。属于海洋工程技术领域。The invention relates to a test device, in particular to a test device for a large-tonnage upper block continuous lifting system. It belongs to the field of marine engineering technology.

背景技术Background technique

海洋油气资源的开发需在海上布置一定数量的海洋石油平台。海洋石油平台主要有两种类型：固定平台、浮式平台。The development of offshore oil and gas resources requires a certain number of offshore oil platforms. There are two main types of offshore oil platforms: fixed platforms and floating platforms.

海洋石油固定平台一般包括：上部组块和水下固定支撑结构。此类海洋石油平台一般是将上部组块和水下固定支撑结构在陆地单独建造，并采用浮托法进行海上安装作业。在大型上部组块的船运过程中通常需要在其下部和船舶甲板之间布置下部支撑结构。对于浮式平台，其一般由上部组块和下部浮体组成，在其下水之前，通常需在场地或船坞完成其上部组块和下部浮体的组对工作。A fixed offshore oil platform generally includes: an upper module and an underwater fixed support structure. This type of offshore oil platform is generally built separately on land with the upper module and the underwater fixed support structure, and adopts the float-over method for offshore installation operations. During the shipping of large topside modules it is often necessary to arrange a substructure between its lower part and the deck of the ship. For a floating platform, it generally consists of an upper block and a lower floating body. Before launching, it is usually necessary to complete the assembly of the upper block and the lower floating body at the site or dock.

对于海洋石油平台的建造，传统工艺一般是先将下部支撑结构、下部浮体等下部结构预制完成，然后，再继续进行上部组块的建造。建造过程中，上部组块需要先提升一定的高度，以便使下部支撑结构、下部浮体等下部结构能够顺利的插入或运输至上部组块的底部。因此，上部组块的提升是整个海洋石油平台组装过程中的重要一环，直接影响到海洋石油平台的建造周期及生产成本。For the construction of offshore oil platforms, the traditional process is generally to prefabricate the lower structures such as the lower support structure and the lower floating body first, and then continue to construct the upper modules. During the construction process, the upper block needs to be raised to a certain height first, so that the lower supporting structure, the lower floating body and other substructures can be smoothly inserted or transported to the bottom of the upper block. Therefore, the lifting of the upper block is an important part of the assembly process of the entire offshore oil platform, which directly affects the construction period and production cost of the offshore oil platform.

目前，大吨位上部组块连续提升系统的提升能力已达到35000吨，提升高度为60米。由于上部组块的吨位较大，提升高度较高，作业时间较长，因此对上部组块提升系统的工作性能可靠性要求极高。如果直接进行提升作业，提升系统作业的存在潜在的风险不易发现，这就要求在提升系统实际作业之前，需对其工作性能进行检验，以测试其工作指标是否达到要求。At present, the lifting capacity of the large-tonnage upper block continuous lifting system has reached 35,000 tons, and the lifting height is 60 meters. Due to the large tonnage of the upper block, high lifting height and long operating time, the requirements for the reliability of the working performance of the upper block lifting system are extremely high. If the lifting operation is carried out directly, the potential risks of the lifting system operation are not easy to find. This requires that before the actual operation of the lifting system, its working performance needs to be inspected to test whether its working indicators meet the requirements.
