Abstract

The invention discloses an ocean flexible pipe protection device, which mainly consists of an iron chain, a hanging connector, pull rods, a protection net, middle connectors, a centralizing connectorand a centralizing rubber ring, and is characterized in that the upper end of the iron chain is hung on a lifting lug of a boat body; the lower end of the iron chain is connected with the hanging connector; the hanging connector is connected with the upper end of the pull rod through screw threads; the pull rod and the other pull rods are connected through the middle connectors; the centralizing connector is connected with the lower end of the pull rod through screw threads; the centralizing rubber ring and the centralizing connector are fixedly connected through a vulcanization process; the protection net is fixedly connected with the pull rods; each cross section of the ocean flexible pipe protection device is provided with 4 to 8 pull rods connected in parallel; the pull rods are uniformly distributed along the peripheral direction; the structure formed by the pull rods and the protection net is in a tubular shape; a flexible pipe penetrates through the tubular ocean flexible pipe protection device. The ocean flexible pipe protection device has the advantages that the structure is simple; the installation is convenient; the influence of crushed ice or floating objects on the flexible pipe arranged under a deck can be effectively reduced.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a protective device for a flexible pipe used in offshore oil exploration and development, and belongs to the technical field of mechanical engineering. Background technique [0002] At present, the exploration and development of offshore oil and gas resources is shifting from shallow sea to deep sea. The steps of offshore oil and gas resource development mainly include: exploration, drilling and completion, production, storage and transportation, and refining. How to move the offshore oil and gas obtained from drilling from the wellhead to the land, such as transporting the oil and gas in the underwater production system or floating production system to the land, is a key issue in the development of offshore oil and gas. Due to its unique composite structure, flexible pipes have incomparable bending resistance to conventional steel pipes, and are currently being rapidly developed and appli...
