摘要： A floating, offshore drilling and/or production platform is equipped with a rail-mounted transport system that can be positioned at a plurality of selected positions over the well bay of the vessel. The transport system can move a drilling riser with a drilling riser tensioner system and a blowout preventer from one drilling location to another without removing them from the well bay of the vessel. Using the transport system, the drilling riser is lifted just clear of a first well head and positioned over an adjacent, second well head using guidelines. The transport system may then move the upper end of the drilling riser (together with its attached tensioner and BOP) to a second drilling location. A dummy wellhead may be provided on the seafloor in order to secure the lower end of the drilling riser without removing it from the sea while production risers are being installed.
摘要翻译： 浮动的海上钻井和/或生产平台配备有轨道安装的运输系统，其可以位于容器的井口的多个选定位置。 运输系统可以将钻井提升管与钻井立管张紧器系统和防喷器从一个钻井位置移动到另一个钻井位置，而不必将其从容器的井口中取出。 使用运输系统，钻井提升器刚好从第一个井口清除，并使用指南定位在相邻的第二井井。 然后，运输系统可以将钻井立管的上端（连同其附接的张紧器和BOP）移动到第二钻孔位置。 可以在海底上设置虚拟井口，以便在安装生产立管时将钻井立管的下端固定而不从海洋中移除。
