Abstract

The invention provides a local secondary screen bulkhead applied to a B type independent cabin and a ship or an ocean structure. The local secondary screen bulkhead is completely separated from a B type independent liquid cargo cabin shell and attached to a ship inner shell, and an airtight space is formed outside the B type independent liquid cargo cabin shell. An insulation layer attached to the ship inner shell has the insulation function, a splash-proof film ensuring the airtightness is fixed to the ship inner shell through a fixing device, the B type independent cabin is supported through pressure bearing wood, the bottom of a ship is designed to be a strengthening film and used for bearing a small amount of leaked cargo load. The airtight space between the B type cabin shell and the splash-proof film can serve as a construction space and an overhaul space, and the B type cabin shell and the splash-proof film are detected. According to the technical scheme, the structure is simple, installation is convenient, the construction cost of a ship factory can be saved, and the construction period is shortened.

Description

technical field [0001] The present invention relates to a ship cabin structure for transporting and storing liquefied gas, more precisely, relates to a partial secondary screen applied to a B-type independent liquid cargo tank designed according to the requirements of the "International Code for Carriers Carrying Liquefied Gases in Bulk" (IGC code) wall system. Background technique [0002] Generally, for ships used to transport and store liquefied gases below -55°C, such as methane, ethane, ethylene, etc., the cargo containment system can use three types of B-type independent tanks, C-type independent tanks or membrane-type liquid cargo tanks. type. [0003] According to the requirements of the IGC code, the membrane-type containment system requires a complete primary barrier and a complete secondary barrier, in the form of a complete secondary barrier attached to the hull, a complete primary barrier attached to the secondary barrier, and a primary barrier. Walls and seco...
