Cargo compartment section division design method and cargo compartment sections of 80,000-cubic-level film type LNG (Liquefied Natural Gas) ship

Abstract

The invention relates to a cargo compartment sectioning design method for a 80,000-cubic-level film type LNG (liquefied natural gas) ship, a cargo compartment is divided into four compartments including a bottom and bilge section, a side section, a bulkhead and a deck section. The method comprises a cargo compartment bottom and bilge section dividing form, a cargo compartment side section dividing form, a cargo compartment bottom and bilge section dividing form, a cargo compartment bottom and bilge section dividing form, a cargo compartment side section dividing form, a cargo compartment bottom and bilge section dividing form and a cargo compartment bottom and bilge section dividing form. A cargo compartment division form and a cargo compartment deck subsection division form are adopted, each of the four cabins is longitudinally divided into three ring sections. Meanwhile, it is guaranteed that the full-width block of the deck is complete, a low-temperature pipe system on the deck is installed in the total assembly stage in advance, and meanwhile ship body key nodes W4 on the inner wall of the cargo compartment are divided into subsection internal nodes; the invention further relates to a cargo compartment section designed and built based on the method. According to the method disclosed by the invention, the cargo compartment is divided and designed in sections, so that high efficiency and high quality of ship construction are ensured, the construction is completed on schedule, Meanwhile, the construction period is shortened and the coating PSPC standard is met.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a design method for section division of a cargo compartment of an 80,000-cubic-class membrane-type LNG ship. Background technique [0002] LNG (liquefied natural gas) ship is a world-recognized three-high ship with high technology, high added value and high reliability requirements, and is the jewel in the crown of the world's civil shipbuilding. The liquefied natural gas ship needs to be able to guarantee the ability to transport liquefied natural gas at a low temperature of -163°C. The segmental division design during ship construction is the top-level planning of the ship construction plan. Whether the segmental division is reasonable or not will directly affect the fulfillment rate of various technical and economic indicators such as shipyard equipment, product quality, cost and labor productivity. The overall cycle of ship construction and the control of construction cost. [0...

Problems solved by technology

In order not only to meet the installation requirements of the maintenance system, but also to improve loading efficiency, to ensure rapid installation of outfitting parts at the most suitable stage, to minimize damage to the paint during the general assembly or loading stage, thereby improving the integrity of the ship's launching and shortening the wharf cycle, it is necessary Divide the bottom cargo tank and deck into full-width general sections to reduce the number of hoisting and increase the pre-outfitting rate of the total section, while there is no such requirement for the division of conventional tankers
