Submarine Pipeline Carrier

Abstract

The invention discloses a submarine pipeline transporting and loading boat which comprises a submersible carrier formed by two symmetric streamline singletons, the two streamline singletons are connected to each other through a connecting frame; a longitudinal propeller is installed at the stern of each of the two streamline singletons; two vertical propellers are installed on the connecting frame and are arranged between the two streamline singletons in the transverse direction; telescopic inclined supporting mechanisms are fixedly installed on opposite sides of the two streamline singletons respectively and used for bearing a pipeline; a longitudinal guide rail is fixedly connected with the connecting frame and is provided with two walking frames which can longitudinally move; a transverse guide rail is fixedly arranged on the walking frames and is provided with a crane frame which can transversely move; a winch is installed on the crane frame and is wound by an armored cable; and the free end of the armored cable is fixedly connected with a lifting hook which is used for being separated from or connected with a shackle on the pipeline. According to the submarine pipeline transporting and loading boat, underwater transfer of the pipeline and accurate laying of the pipeline in the state of hovering above the underwater installation position can be realized, and operation is reliable.

Description

technical field [0001] The invention relates to the technical field of a submarine pipeline laying device, in particular to a submarine pipeline transport boat for laying pipelines to the seabed. Background technique [0002] In order to develop offshore oil and gas resources, it is necessary to set up various drilling, oil production platforms and transportation tools for oil and gas resources on the sea. At present, countries around the world generally use submarine pipelines as the main transportation method for offshore oil and gas resources. With the development of offshore oil and gas exploration and development, the problem of oil and gas gathering and transportation has become one of the important topics in the development and research of offshore oil and gas fields. However, no matter what kind of gathering and transportation form is selected, the submarine pipeline is an important part of it, and the construction of deepwater submarine pipeline is a key technology...

AI Technical Summary

Problems solved by technology

[0003] Due to the influence of sea surface wind and waves, traditional submarine pipeline construction operation ships must suspend operations when encountering severe weather such as typhoons, which affects the progress of submarine pipeline laying operations, and due to the influence of sea surface waves, the pipeline cannot be accurately laid to the designated location. The installation accuracy is low, especially for deep-sea pipelines. Due to the depth difference of several thousand meters from the water surface to the seabed, the positioning accuracy of the submarine pipelines is greatly reduced due to the influence of ocean currents. When laying pipelines in deep sea, when the pipeline is close to the installation position Observation and auxiliary operations are usually carried out by underwater robots, which not only increases the operating cost, but on the other hand, the umbilical cables of underwater robots are easily entangled with suspension ropes, which greatly reduces the operational reliability of submarine pipeline laying operations
