What Is a Guide Frame?

The guide frame is a component of the guide device of the marine drilling underwater device. There are four main pillars around the guide frame, and four guide ropes are tied to it to guide the underwater equipment such as the BOP group in place. The catheter head for the first drilling was hung on the wellhead disk and connected to the guide frame. A short central tube in the center of the guide frame is connected to the catheter head so that the casing and the casing head are in place. ^[1]

Brackets that allow only unidirectional displacement of the pipe. It can limit the displacement direction of the pipeline on the vertical pipeline and prevent the

In general, the structural design calculation of the guide frame needs to consider two basic variables, one is the structural

When the floating production, storage and handling system (FPSO) is operating at sea, a single-point anchoring system is generally used for mooring for the stability of the floating ship. The single-point anchoring system needs to drive independent steel piles underwater, and link the steel piles and the pontoon with anchor chains to stabilize the hull. When the underwater independent steel pile is inserted at sea, the underwater independent steel pile guide frame (hereinafter referred to as the guide frame) is required to guide and straighten the pile to meet the installation accuracy requirements of the underwater independent steel pile. Since such steel piles vary from one stratum to another, there is no ready-made product for the guide frame. ^[5]
