Abstract

The invention discloses a mounting tool for an underwater horizontal connector. The mounting tool comprises a positioning plate, a drive plate and an aligning plate all in inverted U shapes. The positioning plate, the drive plate and the aligning plate are all sequentially and fixedly fixed on two parallel guide bars. The positioning plate, the drive plate and the aligning plate can be sleeved on the horizontal connector to be mounted. The mounting tool is provided with a radial locking mechanism capable of preventing the horizontal connector from moving radially along the radial locking mechanism. The radial locking mechanism comprises a rotating device and a retainer plate connected with each other. The drive plate can move along the guide bars. When moving along the guide bars, the drive plate can drive a drive ring of the horizontal connector to move; a power mechanism arranged on the aligning plate can drive the horizontal connector to axially move. According to the unique connector-separated lifting scheme design, a connector body is lowered and roughly positioned first before the mounting tool is lowered and precisely positioned; the stepwise implementation helps reduce loss caused by misoperation.

Description

technical field

[0001] The invention relates to an installation tool for an underwater horizontal connector, which belongs to the field of offshore oil engineering. Background technique

[0002] At present, the development of deep-water gas fields is a new field of energy industry with high investment, high risk and high-tech intensive. Among them, the subsea manifold is an important equipment in the development process of deep-water gas fields, and the connection mode of the manifold is very complicated. The connection method of the traditional land manifold is difficult to meet the needs of deep water operations, so the underwater manifold connector has a new structure and operation form, and the subsequent connector's lowering and installation tools also play an important role in the field of deep water pipe laying. status.
