摘要： A top-tensioned riser system comprises a substantially vertical riser extending upward from the seafloor; a conductor surrounding an upper portion of the riser in spaced-apart relation; a coaxial keel guide surrounding a lower portion of the conductor; a tensioner attached to the conductor and the riser; a keel guide support structure attached to the keel guide and connected to the keel of a dry-tree, semi-submersible vessel; and, a keel joint centralizer attached to the riser proximate the keel guide and sized to prevent radial movement of the riser relative to the conductor. Side loads on the riser (such as those arising from displacement of the vessel from its nominal position or currents acting on the riser) are reacted from the riser to the conductor via the keel joint centralizer and then to the keel of the vessel via the keel guide.

摘要： A hawser system between a tension leg platform (TLP) and another vessel employs two lines, oriented in a V-shape, to restrict the vertical motion of a hawser near the bow of the other vessel which may be a semi-submersible tender assisted drilling vessel (TAD). Drilling operations may be performed from the TLP while the semi-submersible provides the supporting services for the drilling operation, e.g. drilling fluid and drill pipe storage. The restricted vertical motion of the hawsers significantly reduces the possibility of the hawsers contacting each other. A hawser system according to the invention couples the semi-submersible TAD vessel to the TLP and may be implemented without passing the hawsers through sheaves.

摘要： A system comprising a semisubmersible, at least two offloading terminals and shuttle tankers in optional combination with an FSO may be deployed in deep water harsh environments where riser performance (either SCR or LWSCR) is a key performance parameter. The semisubmersible is used to support the risers because of its favorable motion characteristics under harsh conditions. The semisubmersible supports the entire process train and provides well maintenance, which may include water and/or gas injection. The semisubmersible may provide work-over capabilities for well intervention. The produced hydrocarbons are exported through flexible pipes to at least two off-loading buoys. A FSO or shuttle tanker receives the produced hydrocarbons. Two or more off-loading buoys may be employed to allow for uninterrupted production when a shuttle-tanker-only embodiment is utilized.
摘要翻译： 包括半浸泡，至少两个卸载端子和与FSO可选组合的穿梭油罐的系统可以部署在其中提升管性能（SCR或LWSCR）是关键性能参数的深水恶劣环境中。 由于在恶劣的条件下它具有良好的运动特性，所以半浸泡器用于支撑立管。 半潜式船支持整个过程列车，并提供良好的维护，其中可能包括水和/或气体注入。 半潜式人员可以为井下干预提供工作能力。 生产的碳氢化合物通过柔性管输出至少两个卸载浮标。 FSO或穿梭油轮接收生产的碳氢化合物。 可以使用两个或更多个卸载浮标来允许在仅使用穿梭式罐车实施例时不间断地生产。

摘要： A tendon is assembled in a horizontal orientation using connectors or by welding at a weld station on a barge or other vessel located at or near the installation site of a tension leg platform. During assembly, the tendon is pulled away from the assembly vessel and tensioned by a tug or offshore work vessel. When fully assembled, the tendon may be up-ended in a manner similar to a wet-towed tendon, and then either pre-installed using floats or passed over to a TLP which is on-site and ready to receive tendons.

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.
