An offshore platform bulkhead structure with anti-explosion, fire prevention, insulation and noise reduction

Abstract

The invention provides an explosion-resistant, fireproof, insulating and noise-reducing bulkhead structure of an offshore platform, which includes a pair of sandwich panels arranged in parallel up and down and an impact-resistant structure. The impact-resistant structure consists of three leaf springs respectively. The upper and lower trapezoidal groups, damping material is arranged between the upper and lower trapezoidal groups, the adjacent upper and lower trapezoidal groups are connected by shock-absorbing springs, and the interior of the upper and lower trapezoidal groups is filled with the first filler; the sandwich panel includes a pair of upper and lower skins arranged in parallel The outer surface of the skin board is coated with an insulating layer, a sandwich board is sandwiched between two skin boards, and the gap between the sandwich board and the skin board is filled with a second filler. The invention has the advantages of anti-explosion, fire prevention, insulation, noise reduction, simple structure, easy coating construction and quality inspection, short construction time and is suitable for rapid repair and the like.

Description

technical field [0001] The invention belongs to the field of ocean engineering, in particular to a bulkhead structure of an ocean platform. Background technique [0002] With the development of the world economy, onshore oil and gas resources are basically exhausted, while oceans are rich in oil and gas resources, and the focus of human resource development has shifted to the ocean. Offshore oil and gas exploitation must rely on offshore platforms. As we all know, offshore oil and gas development has the characteristics of high investment, complex technology, difficult construction, harsh operating environment and many random factors. As the infrastructure for the development of offshore oil and gas resources, offshore platforms have been in complex and harsh marine environments for a long time. In addition to normal working loads and environmental loads, they are often affected by risk loads (explosions, fires, collisions, etc.). The risks mainly come from the defects of ...

AI Technical Summary

Problems solved by technology

Although this method can effectively prevent the deformation and damage of the bulkhead caused by the explosion, when an accident occurs, the bulkhead does not have a good buffer area and cannot achieve a good shock absorption effect, and it cannot meet the requirements of explosion resistance and fire protection during daily service. , insulation, noise reduction and other multiple functions

The existing bulkheads have deficiencies in explosion resistance, fire prevention, insulation, noise reduction, and shock absorption during high-energy impacts, which need to be further improved.
