Fireproof anti-detonation self-escape multifunctional cabin

Abstract

The invention discloses a multifunctional cabin for an ocean platform, belongs to the technical field of safety of cabins for crews, and particularly relates to a fireproof anti-detonation self-escape multifunctional cabin. The multifunctional cabin comprises a cabin body comprising a spring vibration isolator at the bottom of the cabin and a cabin restraint device. The enclosure walls at the periphery and the top plates of the cabin are composite sandwich panels; the bottom of the cabin is connected with a platform deck by using the spring vibration isolator; and the cabin is daily restricted and released when in danger by using a restraint clamping plate and a gear transmission mechanism. Compared with the prior art, the multifunctional cabin can enable the staffs in the cabin to be in a fireproof anti-detonation safety protection state around the clock, and can be automatically separated from a main deck platform under the action of a buoyancy force when the platform collapses and enters into water to achieve the life-saving effect, thereby having a good application prospect.

Description

technical field [0001] The invention relates to a fireproof and anti-explosion self-escape multifunctional cabin, which belongs to the technical field of crew cabin safety. Background technique [0002] With the continuous development of marine resources development, the number of offshore platforms is increasing, and the safety accidents of offshore platforms are also increasing year by year. safety is immediately threatened. As offshore equipment for drilling oil and gas resources, offshore platforms have two main types of safety accidents: one is platform explosion or fire caused by accidental oil and gas leakage; the other is offshore platform collapse due to harsh sea conditions or ship collisions. [0003] At present, most of the working and living cabins of offshore platform personnel are steel cabins with ordinary frame structure. This type of cabin has the following three shortcomings in terms of safety: (1) Poor fire prevention ability. The design is mainly to co...

Problems solved by technology

[0003] At present, most of the working and living cabins of offshore platform personnel are steel cabins with ordinary frame structure. This type of cabin has the following three shortcomings in terms of safety: (1) Poor fire prevention ability. The design is mainly to coat a layer of fire-resistant paint on the surface of the steel plate, but due to the ductility and strong thermal conductivity of the steel, it is highly sensitive to temperature. In the event of a fire, the temperature of the steel will rise sharply and the deformation will increase. , the fire retardant coating will fall off quickly, and it is easy to cause the items in the cabin to reach the ignition point and cause a fire

(2) Insufficient anti-explosion and impact resistance. The surrounding walls of offshore platform cabins are generally ordinary plate frame structures, and the bottom is directly welded on the deck of the offshore platform, with high rigidity. Once an oil-gas explosion occurs in the oil-gas-intensive area outside the cabin, On the one hand, the shock wave load can directly destroy the cabin wall and damage the cabin; on the other hand, the severe vibration of the deck of the offshore platform caused by the explosion will cause damage to the equipment or personnel in the cabin through the bottom of the cabin.

(3) The cabin has no self-escape ability, and the offshore platform mainly relies on the equipped lifeboat to achieve the purpose of escape. When the offshore platform is in danger and needs to abandon the platform, it is necessary for personnel to enter the lifeboat from various cabins through the platform deck, which inevitably causes a period of time for personnel. Exposure to the platform deck for a long time, if the explosion or fire on the deck continues at this time, there is still a threat to the safety of personnel
