摘要： A subsea Christmas tree coupling having a radially outer connection, for example a tree surface and a conductor housing, adapted to make a rigid joint with a conductor casing. A radially inner connection, for example a depending skirt of the subsea Christmas tree, is adapted to make a sealed joint directly with a casing hanger assembly of a mudline suspension system. The invention thus substantially eliminates the use of additional hangers besides those of the mudline suspension system, simplifying the coupling assembly, and providing the possibility of reduced stackup heights. The relatively compact and simple coupling results in shorter installation times and lower costs. The rigid joint between the coupling and the conductor casing ensures that any external loading is transferred to the conductor casing.

摘要： A subsea system comprises a central template that is piled into the seabed and carried wing modules that are connected to the template by hinges. This allows the template to be deployed and the wing modules attached subsequently or for the wing modules to be folded upwardly into a collapsed disposition as the template is deployed. In either case, the template can be deployed through the moonpool of a vessel and does not require a heavy lifting barge. An example of a module usable with the template is a hinge-over guidebase which can allow the commencement of drilling of a well while a manifold and christmas tree are being constructed for subsequent attachment. Thus, installation of the system is easy and drilling of the well can commence quickly.
摘要翻译：一个海底系统包括一个中心模板，该中心模板堆放在海床中，并带有翼模块，通过铰链连接到模板上。这允许模板被部署，并且随着模板被部署，随后的翼模块或翼模块向上折叠成折叠的配置。在任一情况下，模板可以通过船只的月球进行部署，不需要重型起重驳船。可与模板一起使用的模块的示例是铰链引导基座，其可以允许开始钻井，同时构建歧管和圣诞树用于随后的附接。因此，系统的安装容易，井的钻井可以快速开始。
