摘要： A method of handling a discrete elongate subsea element of determinate length, such as a spool of rigid pipe is disclosed. The method includes shortening a tensile chord system acting on longitudinally-spaced locations on the element to apply longitudinally-compressive forces to the element. The compressive forces bend the element along its length against elastic recovery force to shorten the span of the element. One end of the element is anchored at a first anchorage before or after the element is bent. The other end of the element is anchored at a second anchorage, after the element is bent and while the element remains bent. The method is apt to be used during installation of the element, where the anchorages are both underwater, and during transportation of the element, where the anchorages are hang-off platforms of a surface vessel.

摘要翻译： 公开了一种处理具有确定长度的离散细长海底元件的方法，例如刚性管的卷轴。 该方法包括缩短作用在元件上的纵向间隔位置上的拉伸弦系统，以向元件施加纵向压缩力。 压缩力沿着其长度抵抗弹性恢复力弯曲元件以缩短元件的跨度。 元件的一端在元件弯曲之前或之后锚固在第一锚固处。 元件的另一端锚固在第二个锚固处，在元件弯曲之后并且元件保持弯曲。 该方法易于在元件的安装期间使用，其中锚固件都在水下，并且在元件的运输期间，锚固件是表面容器的悬挂平台。
