Expansion type offshore oil and gas platform anchoring pile bolt device

Abstract

An expansion type offshore oil and gas platform anchoring pile bolt device comprises an anchoring pile bolt and a piling tool. The anchoring pile bolt is provided with a fixed mooring rope, a steel rod positioning hole, a pile body, a pile claw and a pile head, one end of the fixed mooring rope is connected with the offshore oil and gas platform, the other end of the fixed mooring rope is connected with the pile body of the anchoring pile bolt, and the periphery, close to the upper end side, of the pile body is provided with an annular groove where the fixed mooring rope is wound; the pile body is composed of a circular steel structure, a surface structure is arranged on the outer circumferential surface of the pile body, and the firmness degree of the pile body when the pile body is installed on the seabed is improved through the surface structure on the outer circumferential surface; the upper part of the piling tool is provided with a heavy hammer, the heavy hammer can be an iron block, and the lower end surface of the heavy hammer is provided with a plurality of grooves along the radial direction; moreover, one end of the piling tool is flexibly connected with the sling, the other end of the piling tool is rigidly connected with the positioning steel rod, one end of the sling is connected with a winch on the ship, and the other end of the sling is connected to a heavy hammer of the piling tool.

Description

technical field [0001] The invention belongs to the technical field of marine energy, and relates to a large-scale offshore oil and gas platform mooring pile and tie device, in particular to an expandable offshore oil and gas platform mooring pile and tie device. Background technique [0002] The rapid development of the world economy has brought about a large amount of energy consumption, and oil and natural gas are still the main energy sources at present. However, the world's oil and gas reserves are rapidly decreasing, and the shortage of onshore oil resources has become increasingly prominent. The ocean is not only the living space for human beings, but also an important natural resource and means of production in the production of human society. The development of human society cannot be separated from the development and utilization of marine resources. Therefore, we must march to the sea and vigorously develop offshore oil and gas resources. [0003] The ocean is r...

Problems solved by technology

This technical invention, in view of the outstanding problems mentioned above, proposes an inflatable offshore oil and gas platform mooring pile device, which not only solves the anchoring force requirements of large oil and gas exploration platforms, but also solves the problem that the mooring chain must be tangent to the seabed The problem of too long anchor chain also has the characteristics of detailed facilities, convenient operation, large working water depth and flexible movement, which can better meet the needs of offshore oil and gas platforms in the direction of deep water and large-scale development
