Reciprocating type insulating and fireproof cabin penetrating structure of floating production, storage and offloading (FPSO) device ship

Abstract

The invention discloses a floating production, storage and unloading device ship reciprocating insulating and fire-proof penetration structure, which comprises a support plate (1), a positioning plate (2), a pressure plate (5), a fixing bolt (7), and a first web (8), the second web (9) and the cylinder (10), the support plate (1) is fixed on one side of the cylinder (10), the positioning plate (2) is fixed on the support plate ( 1), the first web (8), the second web (9) and the cylinder (10) are welded and fixed on the bulkhead (11), the pressure plate (5), the first web (8), the second The two webs (9) and the cylinder (10) together form a stuffing box chamber. The fire-proof cabin penetration structure of the present invention can meet the outlet pipeline connection problem caused by pump vibration after use, and can meet the fire-proof insulation requirements of cabin A60. It is simple and reliable to install, easy to maintain, and convenient to replace the fire-proof insulation layer, so as to reduce construction difficulty and improve safety. Support, increase production and operation efficiency, and reduce costs.

Description

technical field [0001] The invention relates to the field of FPSO [floating production, storage and unloading device] ship deck fire-fighting pipeline system engineering field, in particular to a floating production, storage and unloading device ship reciprocating insulating fire-proof penetration structure. Background technique [0002] With the gradual development of deep-sea oil fields in the world, the demand for FPSO ships in the international market is increasing. The safety processing device is an integrated device for industries such as petroleum and ships. FPSO is a key facility for the development of offshore oil, which is both technology-intensive and capital-intensive. The design, construction and installation technology of FPSO fully reflect the industrial manufacturing level and offshore oil production level of a country. Develop comprehensive capabilities. [0003] The main deck fire protection system is involved in the design and construction of Petrobras' "...

AI Technical Summary

Problems solved by technology

[0003] The main deck fire protection system is involved in the design and construction of Petrobras' "MV26" project. This system is the most important fire safety guarantee for the whole ship and the upper oil and gas production and processing equipment. The core power device of the main deck fire protection system is at the bow / stern A large main fire pump is placed in the fire pump room. Because the power of the main fire pump is driven by a medium-speed diesel engine, the high-frequency vibration amplitude before and after the outlet pipeline is severe during operation, and the vibration amplitude of the pipe with a diameter of 700mm can reach 20 mm. Ordinary pipeline penetration structures are generally welded and fixed. Once the position is welded and fixed, the force of the pipeline amplitude will directly press the outlet pipeline, and the expansion joint of the outlet pipeline cannot withstand such a large vibration pressure, which will lead to The expansion joint at the outlet of the pump body is quickly damaged, and in severe cases, the pump body may even be shattered, making the fire pump unable to operate safely, resulting in huge safety hazards and high maintenance costs
